- Some of the Google apps/framework files seem to be broken somehow. Replaced them with older version that seem to work. Update from GooglePlay if you need. Will try to update them in the rom, but for now this should be fine.
————————————-
- Updated Russian, Polish and Hungarian (approx 95%) – new version of IdeaFriend is not translated
- Updated Italian, Spanish, German and Portuguese here and there
- Updated GoogleApps and GravityBox
- Update kernel to S150
- Optimized png files in almost all apps
- Revised scripts and replaced sqlite3 binary with faster one
- Scrolling in lists and animations should be smoother

Then you can try to restore the messages from the backup and see if it will still work (not tested with restore).

Update Lambda v2.2.1 to v2.3.1 (CWM/TWRP)

Due to several request, this flashable CWM zip updates v2.2.1 to v.2.3.1.
User settings and installed aps should stay in tact, but keep in mind there might be some mistakes. I tried to include all changes.
Tested with clean installation 2.2 -> 2.2.1 -> 2.3.1, so there's always possibilty it doesn't work for you with all installed apps.
As always make a full nandroid backup first!

V2.2 (CWM/TWRP)
| Hidden-text |

- Fixed issue with Lenovo Browser, it's now there
- Added raw multilanguage support, but translations vary from language to language and from app to app. Translated many apps. Supported languages/locales – af am ar bg bn ca cs da de el en_GB es es_US fa fi fr hi hr hu in it iw ja ko lt lv ms nb nl pl pt pt_PT ro ru sk sl sr sv sw th tl tr uk vi zu

Update from V2.2 to 2.2.1 (Patch)
- Fixed* callerId matching issues, however it's adjusted for Bulgarian GSM numbers, so it might not work in your country. Credits to C3C076 from xda!
- Chinese city names removed from contacts and call logs – not displayed anymore
- Fixed problem with initialization of Sony Clear Audio in config files
- Standard launcher modified, theme is removed. All needed icons/styles are encapsulated in the launcher.
- Added two additional and helpful options in power menu – Reboot and Recovery
- Boot/shutdown animations changed to Lenovo
* You will need to manually remove all contacts and import them again in order to activate the fix. Also remove all message threads. After that new ones will be grouped correctly
Update script tries to keep all user settings, so your launcher screens and wallpaper should be preserved. However, if you flash the update over a fresh V2.2, you will still need to remove the lotus and missing widgets from launcher screens, then change the background if you want. As always, make a full backup, just in case. Script wipes cache partition and dalvik-cache, so first boot will take time. I will address other issues in future version, but it might take longer time to release it. So far updates were very frequent, but as the ROM gets mature enough, it doesn't require many changes. Please report any problems you encounter, they are taken into account.

LenovoSystemUI-mod-CWM (CWM/TWRP)
- Updates SystemUI with 1% battery mod
- Updates to empty SIM display mechanism. Indicators for unpopulated slots are now hidden. Credits to C3C076 from xda.

Install ROM:
V2 and up
Download desired zip and copy on sdcard.
You need a modified recovery to install the firmware and updates. If you have it already, proceed to step 3. If you don't have, follow these steps:
1. Download Lenovo drivers, unzip the archive. Turn off the phone and remove battery. Open device manager and connect the phone to PC. Watch for new devices. It will be displayed as МТ65хх Preloader. You need to be quick, because it will dissapear in some second. Click on it with the right button and select update driver. Point the wizard to the driver folder, it will install the correct driver automatically.
If it doesn't work with removed battery you can try to power on the phone and turn on developer options in settings or enter meta mode – hold Volume Down and Power buttons. Then connect the phone to PC again.
2. Download and extract Recovery zip and Flash tools. Run Flash Tools, click on DL DA All With Check Sum, load the scatter file located in Recovery folder, uncheck Preloader and hit Download (F6). Remove battery from phone and connect it to PC. When done, a green circle will appear.
3. Enter recovery mode – hold Volume Up, Volume Down and Power buttons until you see the logo. Make a backup of your current system first. Install new zip.
※Please make a backup of your device before installing or updating ROM

Hi pawelp,
I use 2.4.1 for months without any refreshing and everything works stable, including FM radio that I use every day (outdoor with headphones because of weak signal without hp). Gave up testing another roms because (after customization: launcher, gravitybox, gps etc.) this one seems perfect. Base is clean instalation. Did radio work after install? You may clear app data. Not wishing you a hardware problem.
You may also want to check signal strenght in engeneer mode – connectivity – FM receiver
i also install 2.4.1 update
my antutu 5.3 score is 15809
Hi, infrared. I installed your test version A820_signed_112414_222106.zip, and I found that I don't have the problem of camera but proximity sensor not working. That's fine, but I wanna know what's the feature of this rom?
Yes, it seems proximity sensor does not work on some phones.
It works on mine, but it is from the first batches when the model was just released.
I will try to update drivers in the custom kernel. You can flash the standard kernel (it is in the same folder as the test rom) and proximity will work fine, but you're loosing all the tweaks in the custom kernel, which I think will never be fully functional
Wish Lenovo provided the latest kernel source and not some initial pre-6589T stuff…
I will need some volunteers to test the custom kernel when I make some changes regarding proximity sensor drivers.
It is not possible to test it on my device. The previous problem with touchscreen/LCD was fixed thanks to the numerous tests with old panels and new panels (I had both and was changing them after each test), but there's no way I can change the sensor…
It would be good if someone with that problem provides me a screenshot from the app "Sensor Box) -> proximity and light sensors screens with details opened (button on the left bottom corner).
After flashing A820_4.2_stock_kernel+uboot.zip, everything works fine now!
I found that my A820's chipest is MT6589M, it is different from initial pre-6589T to MT6589M….
And if you need some Chinese information, I'll try to help you everything you need
Almost forgot, I changed touchscreen/LCD, too. Maybe it is the problem from other phones because of the flat cable on the panels??
No, the LCD/touchscreen problem was in the drivers – the ones in the source from Lenovo were old and did not support newer LCD/touchscreens properly.
When I got a new lcd, it had the same problem with my custom kernel, but luckily my old one was still working even if it was cracked, so I could use both and fix the problem, while I can't do that in the case with the sensor, because mine is an old revision and works fine with the old drivers.
Here's the details of sensor
Thanks for the screens. It's the same sensor as mine and it detects the same version too. Maybe it's just a different revision.
Install again Proton – it's great rom! In my phone all works fine execept camera, as you described – in center color spot.
P.S. All sensors works fine too (as i understand i have the same vertion of hardware as you)
Protonz kernel works fine but don’t like that purple spot in my pictures.
It seems that Lenovo is not going to provide us with proper kernel sources and
the camera problem can’t be fixed.
What can go wrong if that proximity sensor not working? I install this rom A820_signed_112414_222106.zip and everything is perfect, only that sensor is not working. Don't have problem whit camera. Only before install i delete few aplications from rom that i not use (Xposed, Adaway, Email, notebook, pico tts, file manager,few google apk, wallpapers….). And for now is working good. Test whit Antutu 5.3 and result is 16200
When you calling, you'll not able to light up the screen unless you press the power button.
