CyanogenMod 10 'Jellaxy'

Original thread here:

Project discontinued because there are by far better CM10.1 releases by Wayland_Ace and others.
Despite that, i got a new device and my good ol' SGA is now in hands of my wife. I hope, i could give something to the community. Thanx for everything..

Most credits go to 'TheWhisp'. So if you want to thank someone, Say thanks to him. He made most of this possible.
Another 'special' credit and a very warm 'Thank you' goes to 'erikcas' who helped me a lot in creating this release.

- Due to the fact that in this latest release cooper device sources did not change, it has ONLY been tested for boot up. No further tests (wifi, bluetooth, etc..) were made.
- Some people report performance increases of UI by removing '' from /system/lib/hw. This has not been tested by me. But you can try and report back here, if it really works. (As always: Don't forget to do a CWM backup first)
- As long as there are no significant changes in CM sources or improvements in device sources, there will be no new CM10 release after this one because focusing on CM10.1 from now on.

Notes about 'Google Now'

Google Now seems to be a general problem in many ROM's. For more information see this thread: If someone wants to do something for this ROM, she/he can check out this thread if there's a solution for us.


Some people asked me, what i recommend to make Jellaxy more reponsible and faster. So here are my personal recommendations for tweaking.

Some words on Tweaking.

During the last weeks, i've read a lot of 'my rom is laggy' posts in general thread and here. I think some words should be said on this.
First of all, be aware that all those 'Turbo' scripts floating around do more or less ALL the same. They all manipulate system and kernel settings by writing values to special 'device files'. Most effective results are/were achieved by writing new OOM values to '/sys/module/lowmemorykiller/parameters/adj' and '/sys/module/lowmemorykiller/parameters/minfree'. Since ICS, writing to this device files via init.d scripts doesn't work anymore, because since ICS those values are overwritten with default values later during boot up. This is why i added code to Jellaxy which makes it possible to set this values in 'build.prop' (See here: This is also, why Supercharger needs a patched 'services.jar' to work in ICS and JB. In the latest release of CM10, i already changed OOM values (based on OOM Calculator by zeppelinox) and lowered the max. number of hidden apps to 10 (See build.prop). I don't think that any script will make things 'revolutionary' better. However, you should always have in mind that:
  • 278Mb stays 278Mb, whatever you do. No script in this world can change this
  • We are on JB and not an GB anymore. JB was never meant to run on devices with just 278 Mb of memory
So i recommend to try to run Jellaxy CM10 without any tweaking script first. Let it settle down and wait a day. Additionally try to limit max. number of Background processes to 4 in 'Developer Settings'.

Try to use swapping, if it makes things better for you or not.

If you want to try out a tweaking script, make a CWM backup first. So you can always revert back if something goes wrong. And always try only one script at a time and DO NOT flash all scripts that promise to give you 'the ultimate fastest machine on the planet'.


Most of you will probably have noticed that for some reason most available scripts have an impact on performance. I recommend to use 'Link2sd' from Playstore. It's the only one i've found so far, which pushes apps, dalvik and system libs to SD without breaking performance.

Have a lot of fun with Jellaxy

[B]Special Remark for Galaxy Ace: Unfortunately Galaxy Ace is the only device where camera driver in kernel is not working yet. We're working hard to solve this problem.

FIT has that problem to :P strange isnt it FIT and ACE have 5MP camera and they dont work. GIO and MINI 3MP work lol... Some camera apps work on FIT so i think they will work on ACE NightVisionCam, twisted camera.

I think problem could be that camera isnt properly recognized all camera apps think that camera is 3MP and we cant put 5MP
