v2.3.5a
- 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
- Deleted line in build.prop that disables JIT compiler. If anyone need it can always add it again.

- Fixed ideaFriend messages grouping. In order to activate the fix, you need to remove all current message threads, then go to Settings -> Apps -> ideaFriend -> Delete Cache and restart phone. 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)
| Hidden-text |

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

a very good and smooth rom, no google calender(my MAIN concern), thans so much!
There is a google calendar. Its lable is just Calendar.
There is a google calendar. Its label is just Calendar.
can u tell me how to load this rom using TWRP recovery??
there is a problem with the bluetooth pairing/
the device reconize my car bluetooth headset but it didn't succsieded to connect to it- it whasn't like that on my previus rom (based on samsung one…) i have the latest virsion you uploaded.
It works for me, but I've tried with another phone only.
Did you try the other ROM before formatting the whole nand flash or after that?
before.
I think your bluetooth address/configuration is wrong, just like it is with IMEI 1, IMEI 2 and MAC address for the Wi-Fi adapter. Maybe the car bluetooth headset remembers the old bluetooth address? I really don't know how conenction between a phone and a headset is done, but both adapters have addresses for sure. You can probably make a backup of your current system through cwm and try the other ROM again?
When you did a full nand flash format you destroyed the clean boot nvram block, so after installing a new rom or a factory reset you're going to get the same errors again, even if you repaired some of them – changes are temporary.
If you have a backup which was done before the format, I can guide you through permanent restore of all these things, but you need to have this backup, otherwise I don't know how to see the original values. It took me many hours to find a permanent solution, but I had the backup. You can probably find part of it in some forums, but not everything in one place, so I did it almost on my own.
i dont have a backup- but i wnow someone how has it.
can you direct me to the file i need?
i deleted the old adress.
that the model- "motorola bluetooth car kit ihf1000"
i posted on an other forom if anyone have this rom & he will tel me could you gaide me where to get to and what file i need?
I fyou manage to find your backup, contact me from the Contact form in the right part of this page. I will try to help you.
anyone have problem with non rotating screen for example in messages ??
I have got as present LENOVO A820E from Chinese guys. It has only chinese applications and has no PLAY MARKET. As far as I understand this one as specifically done for Asian market only.
I was trying to connect it without battery – it doesn't show anything in device manager.
If I start it with VD+P then it shows ANDROID as device. If I start it usual way with loading it shows A820 as device but neither drivers can be installed. Any ideas?
Don't try to install this ROM on any other device, except A820. It most probably won't work on E and it's not compatible with T. You may end up in the same situation like me – broken touchscreen.
You can only try to root it with some tools, then install google apps. Search for MTK auto root.
Infrared – so what shall I do…? It has no market, there is chinese market inside but all in chinese..
will look for mtk auto root then…
Check this thread http://droidchina.com/forum/Th.....-One-click-root . If you manage to root the deviec, then you can install e.g. mobileuncletools and change the recovery, then install google apps for JB 4.1.2, if tthe phone has this Android version.
it has 4.1.2 version
Ok, then that's the gapps pakage you need https://code.google.com/p/lu4n.....n=2&q=from
I guess my recovery might work for A820E, but not completely sure. If you root the phone, place recovery.img on the sdcard and install it frommobileuncle. Then install gapps package from recovery.
can't install usb drivers… from http://droidchina.com/forum/Th.....-One-click-root. pdanet simply waiting on connection for the phone although debugging is enabled.
Have yiu tried other methods for drivers installation? For example this one: http://droidchina.com/forum/Th.....er-on-Windows-7
Thing is that in devices it shows only A820E – not MT65XX.
Somehow from here http://droidchina.com/forum/Th.....ver-For-Windows managed to get connected PDA net is connecting. BUT my XP anyway shows unknown device A820E, SU is installed but it does not have binary so it does not work. Can't install recovery either…
