Perseus X and Gearloose File System Manager

100th POST .Bells and whistles

I was gonna release the Arkas 1.6 but stalled it for a reason.

Arkas 1.6 was going to be Perseus X on JFS .

There is a reason behind it .

Recently Odin Bricks and Failures are on a rise .

I did isolate the stock ROM without the bootloader last week to minimise the Bootloader related errors .

Now Enigma takes a step further to more freedom from Odin .

Ordinarily A regular Odin flash takes 3 minutes ,thats 180 seconds of nervous 216 Heartbeats .

The major chunk of Odin Flash is the system.rfs flash .

Now we have eliminated the requirement for system.rfs Flash

That leaves us with 10-12 second Odin Flash which is much much more safer

Perseus X doesnt use the Normal Flash Method .

PERSEUS X IS A GINGERBREAD ROM >YOU WILL REQUIRE THE GB BOOTLOADER PREINSTALLED WHICH MEANS I5510XWKP5

STOCK ROM SHOULD BE PREINSTALLED .PERSEUS 2 AND ARKAS 1.2GANYMEDE 3 USERS NEED NOT WORRY ABOUT REINSTALLING STOCK ROM AGAIN

IF YOU PLAN ON SPEED READING THIS POST THEN PLEASE NOTE I AM NOT RESPONSIBLE FOR WHATEVER ERRORS YOU MAY ENCOUNTER.

Installing Perseus X is way different .

I am counting on guys like Aelton Lagao(Brazil-orkut ) and didy (Indonesia ) to help your fellow users translate this method .

THIS ROM CAN BE ONLY INSTALLED IF YOU CAN GO TO RECOVERY MODE WITH T + Power

The contents of the file

1.)PerseusX1.tar : (Kernel and Recovery )To be installed with Odin

2.)GearlooseFL.7z : Gearloose File system manager

3.)PerseusX.zip : System to be installed with recovery

Step A .Kernel and the Recovery

Flash PerseusX.tar with One Package Odin Flash.It has the kernel

AND OUR VERY OWN TRISKELLION MOD RECOVERY .

It’s the work of kraka23 and pinkflozd .It’s a full rooted bash recovery with busybox 19.2 with multi FS support .It’s kickass if you know how to use it .

Very powerful .

Kernel is a unique kind .

Very Unique

Theoretically It supports 8 types of File systems ,6 types of /system ,6 types of /data ,6 types of /cache ,8 types of second SD card partition

vfat

ext2/3/4

ReiserFS

JFS

XFS

BTRFS

XFS and BTRFS are not supported for anything below 256 MB so it only works on Second SD card partition .

Usually any kernel can support at most 2 FS .

Pinkflozd’s State of art optimization makes the kernel support almost every FS.rfs may or may not work

More about File system and their effects later .

Step B : Recovery and Gearloose File System manager .

You will need to change the File system partition

Go to recovery .

Connect the phone with USB cable .

Unzip GearlooseFL.7z and run backup.bat.

Yes it is modified Gearloose Backup manager

Press Option 3 which is the Backup Manager

And the required number ahead to change the File system

Format /system to JFS ,ext2 or ReiserFS to be safe

Format /data to ext2 to be on safer side .

Format /cache to ext2 to be on a safer side

Step C : SD card Copy

Copy PerseusX.zip to SD card .

Use the update from SD card option and select PerseusX.zip

Wait

And reboot system .

There PerseusX installed .

The method looks simple but is supremely confusing

The File Systems

Bloat File Systems

Vfat :- It’s slow dated and I never checked it’s working

rfs :- same with this one

ext4 :It’s a jounalled FS and has marginal improvement over rfs .Battery Thirsty

ext3 :Pretty much dated and useless

Fast Action File Systems

ext2 :Non journalled ,Very Fast and responsive .Perseus X works like a charm on ext2

reiserfs : Journalled FS ,this FS is faster than ext2 and the fastest system OS . It’s very fast ,very responsive and smooth.

JFS : It is a bit faster than ext2 . But It has the least cpu foot print in all FS evah. JFS system is 25 p.c more battery efficient than ext4

Power FS

btrfs :It’s fast Second SD card partition FS .Very fast ,a tad battery hog

XFS :It is almost equivalent or faster to btrfs .It consumes a little less CPU than btrfs .

The kernel

Perseus X is powered by the Vigor Kernel 2.0(1.0 was in Perseus 7).It is stable at 806 Mhz . Upto 844 Mhz is unlocked but 806 is max stable for folks .

Below the 600 Mhz the Ram is underclocked for battery safe purposes .

Over 600 Mhz Ram speed is overclocked to give a significant Boost .

It has hundred of patches .BFQ works like a charm for higher CPU range while sio works cool for the lower end of spectrum.

The system :

It’s a regular system with init.d scripts making your life easier and some very cool stuff under the hood with SU 3.0 and busybox 1.19.2 .

It is a Zip file so you can manipulate which system app can be installed .

Currently 10MB is remaining in /system minimum

File System Mismash

It was practically impossible to test every combination o even rationalize every File system combination .The two beta tester did give some results but still it was not enough .

Of all the working combinations in system/data/cache/Sd

ext2/ext2/ext2/ext2 is the most stable one

reiserfs/reiserfs/reiserfs/xfs is the most speedy ROM

JFS/JFS/JFS/XFS is speed + a whooping 25 p.c increase in battery (lagfree-bfq-691)

Reiser/ext2/ext2/ext2 is a relatively safe combnation plus a hevay bump in speed

Problematic FS :ext3 and ext4 act up and 90 p.c of times wont work

JFS is moody FS .6 out of 10 times it will install perfectly .Sometime /data will give you a nightmare ,sometimes the /system wont persist .

Prerequisites : adb logcat knowledge to know .You are screwed .

The Enigma File Systems

Mine is Dual JFS with ext2 cache on XFS SD card second partition

Flozd has Tri JFS on btrfs SD card second partition

Also he has Tri Reiser fs and Tri NonJournalled ext4 btrfs for performance

Tiago has all quad ext2

kraka 23 has tri reisrfs with ext3 and tri rfs ext3 sometimes

File system commands in case of utmost emergency in recovery shell .

/dev/stl12 :- for system

/dev/stl13:for data

/dev/stl14:for cache

System commands have been listed the data and cache are similar

mkfs.jfs /dev/stl12 :for JFS

mkfs.ext2 -b 4096 /dev/stl12 : for ext2

mkfs.ext3 /dev/stl12: for ext3

mkfs.ext4 /dev/stl12: for ext4

mkfs.reiserfs /dev/stl12:for reiserfs

mkfs.xfs /dev/block/mmcblk0p2 :for XFS (sd card second partition only)

mkfs.btrfs /dev/block/mmcblk0p2:for btrfs (SD card second partition only)

Yep ,it’s confusing to install and a bit complicated .You will soft brick it many time and will require assistance from adb logcat .

Arkas 1.6

So it is upto you to decide whether you want a simple Odin ROM for the newer Arkas or should we move forward with the system zip installation .,

Your choice .

Troubleshooting Guide :

If phone doesnt go beyond the log
reboot to recovery and format /data
If phone doesnt boot even after 5 minutes
reboot to recovery and format /data
APPs crashing .Reinstall app .If that doesnt help
reboot to recovery and format /data with another FS
Multiple APK crash
reboot to recovery and format /data and /system to another FS
blocked /data
reboot to recovery and format /data with other FS
I am scared to hell ,WTF is this all mumbo jumbo .
Install Stock ROM .
By Format I mean use mkfs not “Wipe Data and Cache” Partition

I am pickled at the moment .So Long folks .This is a very short tutorial actually.Ask Didy about the problems encountered with Perseus 7 🙂 .

Man………loooonnng storyline…..!!!!!…..specs seem awesome….definitely will give it a try wid help frm my folks……n btw…….by any chance ….will it hav the same graphic bug????I am asking coz this one’s kernel is different…..thumbs up dude..!

1. skilledchaos
  
  October 20, 2011
  
  It’s the longest ROM post . But the tutorial is more a trial and error sort .I dont know abut the graphics bug since I didnt have it .I cant cross test it. It is a heavily patched kernel but I cant promise anything .
  I heard some dude flashed KD4–>DDJK4–>KP1 and the graphic bug vainished . 🙂 .

    Will surely try that sequence shortly…….but I am getting d feeling this rom is gonna b worth all d effort……
    
    N….since so many formats may b required…..can I use a spare sd card…..n den transfer d files wen everything is sorted out…???or maybe on a new sd card…which doesn’t hav any app files, songs n all…….gonna do dat….coz me goin to buy a 16 gb card. Shortly…..hurray!!!!
  2. skilledchaos
    
    October 21, 2011
    
    Sd card has very less relation .you have to format thrice.people rarely format the second partition.mostly it is ext2. Xfs is for the extra nerdy folks
  3. skilledchaos
    
    October 21, 2011
    
    Format is related to the nand inside your phone,I.e place where you flash rom using odin.
    Anyway this is a very unique rom in the android ecosystem .I have never even hear of a kernel supporting more than 3 file system/data/cache mounts.

Hi skilled,
Does this require Stock gingerbread to be installed? im still leviathon 😐
I am thinking of trying this on sunday if i get time.

1. skilledchaos
  
  October 20, 2011
  
  Yep
  Stock Gingerbread is a Pre requisite
  I forgot to mention that 🙂
  Editing Now
  Arkas 0.6 ‘s almost GB successor .
  I may upload the 0.6 since many Froyo users are here .
  The beauty of this ROM is ,if some how you mess it the system up
  with recovery you get Stock PerseusX installed in a jiffy 🙂 .
  This is a long read .

hey can u give us the simple odin one?this maynot work in mine because t+power willnot work for me

1. didy
  
  October 20, 2011
  
  I think Power+T for entering recovery mode didn’t work only for some froyo stock like DXJK5 (South East Asia) and it will work after upgrading to XWKP5 gingerbread stock.

my phone stucks at the log, and i already did the /data reset.. what should i do?

1. skilledchaos
  
  October 20, 2011
  
  No.data format is mkfs format.like
  mkfs.ext2 /dev/stl13
  In recovery shell.
  
  1. fael
    
    October 20, 2011
    
    it’s working now, i just flashed the cache in step B and its working fine now… very great rom, stable and fast !

October 20, 2011

can i just flash this kernel in odin and keep using ur previous GB rom????

1. skilledchaos
  
  October 20, 2011
  
  No .rfs is probably incompatible.there is a 20 p.c chance it may work or it may not.
  if was built for jfs or reiserfs in mind .rfs is just too slow.
  
  1. Aashish
    
    October 21, 2011
    
    i ll go for the ODIN flash ROM coz the only way i can enter recovery is through Widgetsoid Restart widget… and not through T+power thing…

October 21, 2011

didn’t work 😦 (551 india running gany3)
flashed perseusX over gany3 it gave me a std. linux like booting with all those text running
tried manually putting the FS with bb commands & mkfs. 😦
couldnt get into using the zip file as kbd arrows not working in recovery mode
back in stock gb

PS: if I get into recovery shell an ls returns some gibberish characters instead of / (slash)

Hope this helps someone

  File system used ?
  Most errors are due to FS mismatches .
  format the /data using Gearloose FS manager .

  Finish install first. Accept the google terms .when you see the launcher you will get all functions including lockscreen and power menu

hey i am getting this message at the start.UID’s on the system are inconsistent,you need to wipe your data partition or your system will be unstable.and my phone is booting into stock GB even though i installed all the files properly!!!

1. skilledchaos
  
  October 21, 2011
  
  Please mention the file system you are using on /system,/data and /cache. Differnt combinations have different errors.
  UID errors is probably related to reiser system and JFS /data .format /data to ext2 and try again.
  I don’t have time to perform cosmetic changes to Perseus so check the build version and tell me what is it .
  Paste the result of command in root in terminal or adb
  #mount

    what is the advantage over odin? i dont see any plus aside from individuel filesystem?
    
    keep up the good work
  2. skilledchaos
    
    October 21, 2011
    
    A.)you can choose what file system you want .the ext2 based rom is what known as god mode.jfs and reiser are above the god mode.file systems play major role in the speed of rom.willing magics cm is ext2 rom and its very fast as you know
    B.)if you are a rooted user and you somehow mess up system ,you have to use odin to restore the system.here you can just use update.zip option which acts as true system restore (think nandroid) quite unlike the pathetic factory reset which just formats data and cache.
    C.)instead of being dependant on integrity of usb cable and usb port,this method depends on integrity of your sd card .the cable an usb port is major source of odin bricks or failures.odin is only used for kernel and recovery flash .
    D.) It’s a brilliant rom
    
    I can go on and on but by the looks of it I will just create a system.rfs based rom for arkas 1.6 .
    This method is too much of a hassle .

  i might have found a potential workaround for wifi tether in infrastructure mode.
  
  you will need
  android-wifi-tether 3.1b6
  http://code.google.com/p/android-wifi-tether/downloads/detail?name=wifi_tether_v3_1-beta6.apk
  
  wireless tether for root users
  https://market.android.com/details?id=android.tether
  
  1. install both apps
  2. open android-wifi-tether (yellow icon)
  3. go to Settings and change the values of
  a. Change Device-Profile “auto”
  b. Change Setup-Method “WEXT (adhoc)”
  c. back to Change Device-Profile “HTC Hero (GSM)”
  d. Encryption setup method “Auto”
  e. check “Enable WiFi-Encryption”
  leave the rest of the settings alone
  4. close settings and activate tether
  note: tethering will activate but will report errors, this is part of the process
  5. after activating, turn off tether and close app
  6. open Wireless Tether for Root Users (green icon)
  7. activate tethering
  note: this will also again give an error, this is normal.
  8. do not turn off tether yet. go to Settings and toggle “Enable WiFi-Encryption”
  9. tethering will restart and now works as infrastructure mode.
  
  to see if this has been done correctly, check its log, you should see an entry with
  loading ar6000.ko module…
  if you see this, this is correct and tethering will now not crash even with mobile data on. unfortunately, this procedure does not last across reboots. the good thing is that you do not have to redo all the steps. you will only need to start from step 4.
  
  long and winding but i think it works when infrastructure mode is necessary

i tested this now for a little
-installtion is a little bit spongy. i got some problems with other filesystems than jfs however i got it wotking after a while
-it seems there are some wlan problems…i had to reboot sometime after wlan socket crashed (same as in persus before for me)
-quadrant get me a score of 1451…pretty well
-the hole rom dont work total stable with jfs filesystems…will try others
-apps and boot up are very fast and all work with charm…
-a swap partition gives me a great boost. more than i ever had in these roms
-battery drain like all persus but i think all these features get battery a lot to do…logcat allways shows huge number of actions every second

result: everybody who like persus before will love this one.

1. skilledchaos
  
  October 21, 2011
  
  For wlan do
  #rmmod ar6000.ko
  #insmod ar6000.ko
  
  It is equivalent to rebooting WiFi .

Sorry for spam, but i can’t see lockscreen and power menu
I flash the stock ROM, then I have done the step A: Flash PerseusX.tar with One Package Odin Flash
Then I reboot my device, It have no lockscreen and power menu
And
It don’t have “lockscreen and power menu” too when I do step C complete
I think that’s a problem with the boot.img and recovery.img
Please help me skilledchaos

1. skilledchaos
  
  October 21, 2011
  
  Then you reboot to recovery with T+ Power ?
  Format the system partition with gearloose file manager
  apply
  Why will there be a problem with boot.img when the lockscreen lies in the /system i.e PerseusX.zip
  Try to format /system to ext2 and data to ext2 ,update the system with PerseusX.zip and try again .Use gearloose file manager to format .
  There have been many failed installs but there are also clear installs .
  I always check my ROM thrice before uploading it .But I am one human .
  
  I will just create a Odin only ROM for Arkas .
  Perseus X has Ridiculous performance btw .It runs smoothly on 245-480 Mhz lagfree which is less than Froyo 245-667 Mhz . It very fast.

and this is what happen:
Boot log….very long..30sec…the screen off (not off, it black but still shine)
And it stop at that black screen

I’d tried format system with JFS ,ext2 or ReiserFS and data with ext2
I’d tried wipe data at recovery mode
But it not work at all

So…Skilledchaos…This Rom is not compatible with my phone, is it???

but when i check file system .. it shows whatever i format with eg. ext 2 or riesfs..

is this normal?

i seem to be have same “stuck at batt stat” in log boot…
cant proceed forth

1. skilledchaos
  
  October 21, 2011
  
  yes
  because the filesystem check mount the fs
  ext2 /data should do the trick or reiser /data .
  Also flash /cache to ext2 to be safe

See if this steps are right, okay?

First: Use Odin to install PerseusX1.tar with One Package.
Second: Use T+Power, connect usb cable and use backup.bat to format /data with ext2 and /system with RaiserFS ( my choice).
Third: With the PerseusX.zip in sd card, use T+Power to “update from sd card”.

Say if it works, and sure, sorry by my bad and terrible english.

  October 22, 2011
  
  Step 2 :Format /data with reiserfs or ext2
  Format /system with reiserfs or ext2
  Fomat /cache with reiserfs or ext2

very cool custom rom but some details:

– adobe flash is not working
– very slow to turn on
– UMTS network is not working, so I will revert to 0.564

HHHHHHEEEEEEELLLPP!!
i readed the guide,downloaded perseusX,installed it with odin,entered in recovery,used gearloose and formatted everything to ext2,reboot my phone,again recovery mode,installed the update.zip,then restarted,he sad a thing with battery,i flashed to 2.3.4 again but it dont started.now i reflashed again to 2.3.4 and the same thing.he starts,is loading,he restarts,is loading etc

  Perseus ROMs are always a bit different and tad experimental stuff .
  Arkas are usually stable .
  Both come with equal share of bugs and stuff
  I need to check that out .
  Code 32 you say .
  When does it give error
  Odin or USB tethering
  Install the Perseus X JFS if you are having problems with gearloose .
  USB tethering has problems .

    Try changing to another USB port .Tread with caution . You definitely dont want a brick . Odin and USB errors is the reason for creating Perseus X originally .Still kernel needs to flashed with Odin .No Alternative as of now .

fix for missing google apps:
if you have a previous backup (from Titanium) of google apps, you can use that. tested this on google maps. as for updates, don’t know yet. i’ll upload one if anyone’s asking for a copy.
—-

this one’s great! seems to have solved one of the music playback issues i encountered. guess it really was the kernel. though some seem to be unsolvable as samsung themselves have screwed up some aspects of the music player (broken tags and he-aac v2 playback are some).

stable so far. as for battery life, can’t comment on it so far since i left my data on for some time.

system: ext2
cache: ext2
data: ext2
sdpart2: ext2
going to try ext4 with journaling disabled when i find out how.

camera has a little problem though. when in preview mode in camera, there seems to be flickers where there is a section of the screen that is brighter than the rest. also shows up in video mode (and the subsequent video file).

though a boot animation is nice, i love this (does it count as one?) bootscreen! is there a way to enable this even after you get the bootanimation working?

still testing out some aspects of the firmware. aside from the camera problem, so far so good! mine overclocks up to 825 before rebooting. will see if 825 is max (though at this performance, 806 might be more than enough)

1. skilledchaos
  
  October 23, 2011
  
  Try JFS or reiserFS .They are journaled and much faster than ext2
  
  1. g.jie
    
    October 23, 2011
    
    but journaling is bad for flash
  2. skilledchaos
    
    October 23, 2011
    
    True .non-journelling is bad for a operating system and applications .
    Technically ext2 and non journelled ext4 will bring almost equal results .
    on /system ,it doesnt matter .
    on /data it matters heavily .
    the point is using Dual partition SD cards is the best thing reducing the /data usage minimally .SD cards are replaceable .
    I am using XFS on the second partition and it is quite fast .
    Anyway ,nands should last for almost 5 years ,do whatever you want .and you are not going to keep a phone for five years .
    So I will rather go for the fastest (reiserfs/)(xfs/btrfs on SD card) or the CPU light (JFS) and be journelled to protect the integrity than go for ext2 which i had troubles in past (Perseus 1.1 ) .
    It’s a choice alright . Anybody can do whatever he wants .

I can’t use the factory reset function nor wipe data in recovery mode, my user apps are not dissapear.
Although, I flash my phone back to froyo (all user apps are cleaned) then flash to stock GB rom (no user apps). After that, i flash the perseus X Rom, I see my user apps that I installed before, I don’t understand
Please help

1. skilledchaos
  
  October 23, 2011
  
  If you have a second sd card partition .then user apps are directly stored there by Perseus 2 and X
  even if you flash anything all apps are safe in second sd card partition
  After reinstalling Perseus X the apps in second sd card partition are relinked .
  The problem however is lib files are not linked so you need to reinstall problematic apps .

seems that there is a correlation with tethering errors and mobile data. wifi tether works fine WHEN mobile data is off. when mobile data is on mobile ap throws and error. to confirm that mobile data iis causing, i first turned off mobile data and turned on mobile ap and left it to run for a few seconds. all good. while mobile ap is on, turn on mobile data. mobile ap mode immediately throws an error. it does both ways using the switch from settings and apndroid.
will get a logcat later as i’m not home.

the problem is i might have flashed firmware for its CDMA variant (wasn’t marked as such and i’m suprised that there is!) so even if this recovers i’m not sure if the imei is still intact. if not, crap.
and the firmware was taken from samfirmware. XXJK5.

  Check the Enigma forums for basic installation instructions .

  Attempting Perseus X which is very un-orthodox on many fronts on a brand new phone is a hara-kiri
  Install Stock ROM to gain confidence ,
  install ARkas Froyo like Arkas 0.4 Original Ganymede and Arkas 0.564 Leviathan and test them for a few days
  
  Install Stock GB and maybe Arkas 1.2 Ganymede 3 and actually see how much power you will need .
  
  Then if you require power in exchange for the stability ,go for the Perseus .
  Stock GB/Arkas1.2 is more than enough for regular needs .
  Perseus is more of enthusiast/geek ROM

How do I move dex files? I dont seem to be getting that also I have the latest version of Link2SD from Market!

Raman Venmarathoor

November 3, 2011

after my half a dozen rounds with stock-to-perseus, am back in perseus. The main reason for my switching back to stock was FCs with multiple apps.

I believe the reason was Link2SD and app2sd conflict. I had actually forgot abt the app2sd is built-in perseus. This time I didnt try linking. So my assumptions are Link2SD was link already app2sd-d files. which was the reason for multiple FCs.

Also when phone restarts it losses timezone. it switches back to GMT rather than GMT+5:30. Selecting Auto from Network doesn’t help.

There was one more issue I wanted to write here but forgot!

currently perseus JFS for /system and /data, ext2 for /cache and sdcard 2nd partition

thanks
Raam

1. g.jie
  
  November 3, 2011
  
  yes, jfs gives problems to the timezone for some strange reason. that also happens on i9000 units. try using ext2 or ext4.
  
2. Raman Venmarathoor
  
  November 8, 2011
  
  Got the second issue I forgot about.
  
  Its battery usage. I actually got better battery when I flashed OnePackage. But now I’m very bad battery life.
  I mean very bad since it drains battery within minutes if I use something on phone EVEN WHEN CONNECTED TO POWER!. If I use 3g in a good reception area battery drains superfast less than an hour I think.
  
  I dont use any widgets except for power control. I only switch on networks mobile/wifi when needed. Auto-Sync is almost always off
  
  3g network drains more than WiFi. So I mostly browse with EDGE when I’m outside or travelling.
  
  Flashing Perseus X OnePackage will reply later
  
  PS: Outofstation will reply in couple of days

    November 8, 2011
    
    A quadrant benchmark (Free Version, Full Benchmark) and subsequent connection to internet on 3G (good reception, all bars on) for checking with quadrant site drained 5% of battery. From 100% to 95%.
    
    3G was switched ON just after quadrant finished. And switched OFF when quadrant showed the result.
    Total data transfer 5KB!

Hello skilled congrats for the new ROM and its really a kick ass one
i installed it ( i had some problems at first but i did it at last ) and it’s awesome
but i have to ask for some things
1. why the boot screen is changed to these words looks like logcat i guess
2. when i unlock the phone these words appears in a flash and it’s a bit annoying
3. also working on 800 MHZ is always goes to a reboot or a freeze why ???
4. i will send you an e-mail with some modifications that i make and i wish you to tell me if it’s good

thank you for the great work and the good ROM
also i know it’s Perseus so it’s Experimental and i wish to be helping

  If you are using ext4 based perseus – then I suggest moving to xt4 .
  Perseus X jfs has dmesg enabled .(the process thingy)
  Some like it ,some don’t .jfs is meant to save battery and has lowest cpu load . Two hours extra over any rom .
  
  In fact you can run it on 480 mhz without any hassles . It was my rom of choice but recently I am just lazy to flash back from xt4 .

I’ve tried many stock and custom roms but Perseus X is the best and more stable for my device. The only bad note is about the mp3 player. I use Meridian Player, but the “bug” came out also with the pre-installed media player. During the reproduction of the music, if I use the device (expecially if I flip down the notification bar) the sound became very bad, sounds like the cpu is overcharged and the reproduction became irregular, with some “jumps” in the track. I know, the cpu is not really fast and isn’t good for multitasking, but with the stock rom I’ve never heard this kind of problem, the reproduction was always smooth. However, the rom is perfect but this little “bug”.
