I have a Prestigio PMP5080B and i put on it Oma's CM10.1 1.2.4 released today, with kernel from Neox8. Everything is working except rotation. Now I see that you have put a message that we can use xteam kernel, so i flashed it instead of Neox8. Android went in a bootloop and so i decided to flash the rom entirely. Now i can't even boot, because immediately after starting device shows random color lines on screen - this usually happens when i don't use appropriate kernel... but i used xteam earlier and this kernel worked...

Thanks in advance !

Sorry about that. Maybe I did something wrong. Kernel is from here: http://x--t-e-a-m.blogspot.de/

And the Xeo X8 kernel works entirely on the PMP5080B?

On Neox8 kernel, rotation doesn't work, and creaking is heard when headphones are plugged in and there's no sound that's playing (this occurs even in Prestigio stock ROM)

No sound on the headphones? Did you try the sensor fixes?

No, i meant when i plug in the headphones and no app is playing any sound, i hear cracking and creaking in headphones, but this sound is very quiet, so i can't upload it here...

Rotation - i tried all fixes, but none of them worked... Androsensor says "waiting for event" and when i press on the question mark it says "MMA8452Q 3-axis accelerometer, Freescale Semiconductor", so i think it isn't correct

Do the sensor fixes work, when you run the stock kernel: http://crewrktablets.arctablet.com/?wpfb_dl=138

I tried that kernel you posted, but that didn't work either... i guess the kernel you posted is from prestigio ICS ROM 2.0.2. i tried it, but then tried also with kernel from 2.0.3, and rotation worked there, but rotated in wrong directions.

So i mounted system.img from stock ROM and copied sensors.goldfish.so and sensors.rk29board.so to device. Now it is incorrect for 90 degrees. But could you point me to the right fix, maybe i used the wrong ones ?

Thanks for your effort and answers !

Ok, event is there with stock kernel.

Let us see how the sensor is fitted: http://forum.xda-developers.com/showpost.php?p=46398111&postcount=135

The bootloop with Xteam Kernel is due to a BatteriFix present in the oma 1.2.4 (also in 1.2.3). the Batteryservice.smali in services.jar has the fix that is not compatible with the Xteam Kernel because the kernel has the fix inside !

I made a service.jar with the batteryservice from the Oma 1.2.2 and CM10.1 1.2.4 boots...

Rotation didn't work with that file (everything was at ~ 0), but this fix worked for me - "CrewRKTablets CM10.1 Sensor X=Y Y=-X Z=Z Sensitivity 1000000"

Thank you all very much for help !
