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.

    So far I really like your ROM! IT is very sleek and fast…..

    There are only a few problems that I have encountered: No matter what I do the calender app crashes quite often (others do as well, but not so frequently) and the A820 just doesn´t see the app and wont sync the calender. This is really bad since this is one of the most used features of my androids.

    Do you know of any workarounds for this??

      After a few tries I now get an errormessage in Jorte when I try to import from googlecalendar that says: Googlaccount not set"

      Since all of my other services work as expected there seems to be something really broken.

    I have problem. When i'm trying to flash with other than official ROM there is something wrong with screen. Everything is flashing and it's unreadeable :( Please HELP !

    I'm not using the calendar sync and google sync services, so I might have made few mistakes. I'm preparing an update, started it from the beginning and it should be better than the first one.

    Lokacz, I don't quite understand what the problem is. The ROM is a complete dump.

    Ary you flashing with FlashTool? You can't flash that update from custom recovery, however the update will be a CWM-flashable zip. Will upload in some hours.

      Sounds great!

      In the meantime though I have used the deodexed ROM and installed the GAPPS. Advantage is that all of this can be done via CWM. All runs fine now….

      Looking forward to your CWM still, because more is better ;-)

      I have got this ROM and most things are working in this..but a few issues :

      1. The signal strength on 3G sim is low 

      2. In Auto brighness mode, the Min Brightness is good, but the max brighness when in Sunlight is very low and I can hardly anything in the daylight.

    I can deodex, too, but current one isn't. Don't see any benefit for now.

    • 04/27/2013


      I didn´t mean that you should deodex your rom. It was the rom that works for me from all the ones that are available here on needrom….

      I´m looking forward to your fully working CWM ROM!

    All other google apps seems to work for me, except calendar. Trying to understand why.

    • 04/06/2013


      Calendar not working is a problem with the chinese ROM, but I don't know how to fix it yet. I guess it's some sort of hacking the services, just like the guy for the deodexed ROM did. I don't have time for this now and will be away for several theys. When I come back, I will continue. Will try to add multilingual support.
