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.

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.

V2.2 (CWM/TWRP)
| Hidden-text |
SelectShow |
- 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
- Fixed ID3 tags of ringtones, now displayed in English

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

Please help. I have ROM V1, how to upgrade to V2.2.1. Thx.
It's very hard
SP Flash Tool for ROM v1
CWM for ROM v2
SoCr@Te, yes. Second zip I uploaded is the right one. The first one was missing a folder.
Thanks!
I'm in Kenya. Chinese cities do keep coming back even after deleting all contacts, call logs and messages. I deleted them and imported them back from Google Contacts. They still appeared, decided to enter one by one after transferring them to excel. Still they indicate "unknown city" and others in Chinese language.
Kindly help and thanks for the good work.
Hmm, it works for me. Did you install 2.2.1 patch?
If yes and you made all these steps, then go to /data/data/com.lenovo.ideafriend/files/ and delete phone_city.bin. Delete contacts and clear cache from recovery mode. Then import contacts again. Not sure how contacts are stored on Google servers.
Hope it helps.
what can i do if i formated my a820
Do you have a full backup made via recovery? If yes, then it will be easier.
In any case, you need to flash a full firmware via FlashTools. You can use my V1 or any official version you find. Then restore your backup from advanced recovery (stock recovery won't work).
If you don't have a full backup, then you will need to restore your IMEI and mac address. There are various methods, I personally use MTKDroidTools, search for a guide on google. You have the IMEI written in the battery department of your phone.
Problem is there should be 2 IMEI numbers, but I can't tell you what is the other one. Normally it would be the next one, e.g. IMEI1 + 1.
MAC address (for Wi-Fi adapter) – you can restore it if you have it logged somewhere in your wireless router logs. Search for other guides on google how to restore it.
You need to do these steps only if you don't have a backup and if the phone says your IMEI is invalid after you flash a full firmware.
Aaaargh. Every time I restore back previous version, Ideafriend updates to new version and restores chinese characters and city to dialer…
Oh, I see where the problem is. I have DroidWall app and have allowed internet connection for few apps only. IdeaFriend is not allowed to use Wi-Fi or data connection, that's why it doesn't update, I guess.
Let it update, remove contacts and go to /data/data/com.lenovo.ideafriend/files/ then delete phone_city.bin. Hopefully they didin't add something else. Clear cache just in case and import your contacts again. I will see what I can do for permanent solution, but this would mean app won't receive any updates in the future.
Or remove all permissions. Haven't tried that, but it might work.
When I add new contact from phone google account show error. Don't sync. In my gmail account don't appear the new contact. Also, if I try force sync I get error.
I think that it's a bug.
Sorry buddy, but my hands are tied until I recive the new touchscreen
.
There's no way I can test any change in the code. I caon only use an emulator, which is useful for interface testing only.
I have next problem. Some apps doesn't work because ads is blocking. How I can remove blocking ads?
Thank you friend, no problem! I wait.
Please, when you solve this, you can see a problem of m3u lists? When I add a list of mp3 files with names with special chars this songs don't load in nothing player (I try google music, playerpro, poweramp, winamp…)
Please, see also the problem of gps. I say it in a comment before.
Thank you boss!!!!
I've seen that when I add a new contact with native app contacts the program sync ok. But when I add a new contact with another app (such as go contacts), in this case, I get sync error.
I say it for if this information help you to solve it.
hey guys,
where is it located in the settings menu the tethering/hot spot option? Is it present or we have to wait other release? Could be a lack of this kind of model (even if in the specifics is clearly written)?
thank you
In the main menu there is a "personal hotspot" item.
