Lenovo A850 CN ROM (With Success)

- Before this, I managed to flash A850 ROW stock rom.
- Then I got second A850 phone to flash. I used ROW stock rom but failed. I forgot to check the ROM version before flashing it. So now, the second Lenovo A850 is bricked.
- After searching for a while, I managed to search and download CN ROM.
- I got the info from ( A user on that forum said he managed to unbrick his Lenovo A850 using that ROM download from ( So, I downloaded the ROM from the NeedROM link, using the Flash Tool compressed in the same archive, I try flash my Lenovo A850 with success.
- Now my Android Version is 4.2.2, Baseband version A850.V13,2013/09/06 17:49, build number A850_S203_140208.
- After flashing the ROM, there's a problem with Root. The ROM already included LuckyPatcher and Framaroot. But Root access is unavailable. So, I use KingRoot to obtain Root access.
- There's a problem with Google Play Services in this A850 S203 CN ROM. You can't use WhatsApp, Youtube, etc..
- To repair this problem with Google Play Services on Lenovo A850, firstly I downloaded latest LuckyPatcher from ( Current version is Lucky Patcher v5.8.5.apk. Then, download latest Modded Google Play Store, also in that site. Current version is Google Play Store v6.0.0 (Modded).apk.
- Ohh, I almost forgot. To use LuckyPatcher, you will also need BusyBox. I just download and install BusyBox Installer by JRummy from Google Play.
- Install LuckyPatcher, then run it. Use it to install Google Play Store v6.0.0(Modded).apk as system app. Reboot the phone.
- Now you can install Youtube to test if there is any more problem with Google Play Services.
