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.

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.
