ART is not working, so it is disabled. Could not solve this problem.
For full kernel changelog, visit my github repo: https://github.com/infraredbg/Lenovo_A820_kernel_kk
GPU overclock (works on some A820):
Currently it is only supported via init.d script
Go to /system/etc/init.d and open 00proton with a text editor
Uncomment and change desired value (all values are explained in the script)
Save and make sure the file has correct permissions
Reboot device
You can verify if the GPU frequency have changed in /proc/gpufreq/gpufreq_var_dump
Installation:
If you're currently using one of my DEV roms, it is recommended to do a clean install
It is recommended to use my TWRP 2.8.4.0 recovery (install via Rashr from PlayStore on phone or from FlashTools on PC)
Copy zip on sdcard and optional GApps package and reboot to recovery
Do a full backup of your current ROM including nvram block (IMPORTANT)
Wipe system, data and cache from TWRP. The script does not do automatic format.
Install ROM zip and GApps (optional)
Reboot system (first boot takes time)

Привет, у меня датчик приближения не держит дисплей выключен во время разговора, он срабатывает, отключает дисплей и через секунду дисплей снова включается. И еще не помешало бы покрутить настройки звука, а то громкость входящего звонка и громкость громкоговорителя при разговоре очень тихие.
Go to Settings -> Proton -> MTK Engineer Mode -> Hardware Testing -> Sensor -> Light/Proximity Sensor -> PS Calibration -> Change Threshold
Then change Low value (second value) to a greater number, like 220, 230. Test and report back if some value works for you. Thanks.
infrared, try 220 or 230 but i get error “invalid value”
My bad. You need to enter values in both boxes. Enter 180/220 or 180/230 and test.
Standard values in kernel are 180/210.
problem with storage internal storage of 2.15 not used it uses mounted sdcard how do i change this?
What happens if you change it from Settings -> Storage?
nothing happens it is still saving in sd card even after reset
Tell me what do you expect to happen. For example, which app you want to save there?
Because when I set Phone storage as primary storage in Settings and restart the phone, then test with Camera, the image is saved in internal sdcard and not on the external.
Otherwise you might need to edit boot.img ramdisk and swithc the places of both cards, but most of the people want external card as primary storage.
infrared, try 180/220 or 180/230, restart phon, but nothing has changed, the problem is still.
I can't tell you the exact values. Try different combinations, 180/220 was just an example.
And restart is not required.
Hello. Very good rom.
After wiping I have this error http://i.imgur.com/OewlhiU.png
Is this something dangerous?
Nope. You can disable MTP mode in Mount -> Disable MTP.
But this setting will be restored if you wipe internal card. And all other TWRP settings too (like brightness, vibration, etc.).
Nothing to worry about.
Ok, guys. I have a working method (with minimal possible effort) for restoring nvram backup and also for safe repartitioning.
I will write a guide tomorrow.
Hi,any chance to add swedish lang?
Hi Infrared,
Many thanks for your effort on A820 !
Hope the guys, who flashed Infrared's Proton KK ASOP without data lost problem of IMEI, Wifi mac and BT address , can share your experience to us too.
Thank you.
! a guide on how to safely repartition will be great
I flashed w/o any problem. I had 4.1 version s138 by linerty
My steps was:
1. Install TWRP 2.8.4.0
2. Repartition memory by Petro1990 method from 4pda.ru
3. Install A820-PROTON.KK.V1.0
4. Install Proton-GApps-Mini-4.4.x-20150716
5. Correct ACCDET.kl and mtk-kpd.kl for proper work of headset
Now everything works perfectly. Thanks to Infrared again.
Thanks for the guide.
The question is – if someone has already repartitioned with meteos than should he revert to default partition setting and repartition again in step 2?
