Hi guys, I promised I'd report back.... The so-called ausdim kernel is flashable and works on 4.2.2 samsung roms such as omega and Djembey. In his words "this is a kernel compiled from GT-I9505G sources and packed with MF8 initramfs....Is not something special, is a stock kernel i compile because i see some diffs between I9505 & I9505G sources.." It's main pros are that you can overclock, limit the CPU frequency, undervolt, switch governors and schedulers etc. You do this using the https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod&hl=en Trickster mod app from play store. You can download the kernel here: http://forum.xda-developers.com/showthread.php?t=2342298, although the latest "test" version, version 12, is rock stable and appears slightly better, available here: http://forum.xda-developers.com/showthread.php?p=43970516. Simply download zip and flash thru your custom recovery. Features: Updated Linux kernel to latest 3.4.54. Reworked from scratch CPU OC - UC - VD. (Many thanks to @ktoonsez)) All cores runs at frequencie you set. (That is very important and you can chek it with kernel tuner app from playstore) All cores runs on ondemand governor. (That is also very important and you can again chek it with kernel tuner app from playstore) Added faux sound control (Thanks to @faux123 for his work) Added kthermal and auto_hotplug. "mpdecision is not works because auto_hotplug take his place if you whant to completly remove mpdecision you can rename /system/bin/mpdecision to mpdecision.back but if you change to other kernel do not forget to rename the file". (Thanks again to @ktoonsez)) Max CPU OC @ 2160000. (I dont need more) GPU OC steps 128/200/320/450/600 (Disable some frequencies because of the new method ktoonsez use to OC, all apps exept his app doesnt whant to set anything). Added Fading-led mod and it is working with everything, Missed call-sms user apps etc... Disabled Gentle Fair Sleepers. Enable Fat/MSdos/Vfat and Ntfs(as module) Filesystems (Thanks to @ktoonsez)) Added CIFS as module. Ioschedulers: row-bfq-noop-deadline-fiops-sio-vr-zen-fifo-cfq. Added fast charge. Verdict Had on for several days, have limited CPU and undervolted. Rock stable and all apps on phone working glitch free, no fc's. Doesn't make a huge difference as stock kernel already very good indeed, but slightly better battery for me. Great if you want to squeeze every drop of battery out of your phone, or experiment with overclocking and performance.
