Anyone have a link to a chinese rom instead of a ROW rom. My S850 came with this – vibeui_v9.5_9422_3_st_s850

The ROW roms have wiped my imei's and messed it up.

hi,
imei invalid is not because row version or cn version, because you wipe nvram partition that stored imei. try this first install android 4.2 rom, root it and install mobile uncle tool. with mobile uncle restore all your imei with this guide http://bit.ly/1nKiGOH after success still with mobile uncle backup your imei, and now you can free modified your RoM without afraid losing imei again.

thank you

hi,
losing IMEI will disable your communication, it means you cannot call, messages, internet etc that need mobile signal,
like i said before :
1. back to android 4.2, CN or ROW no problem
2. Root it, using framaroot.
3. install mobile uncle, restore your IMEI using mobile uncle following this guide http://bit.ly/1nKiGOH
4. After successful restore try to dial *#06#, see if your IMEI still invalid or not if still invalid repeat the mobile uncle until success
5. backup your IMEI using mobile uncle
6 finish, you can modified your device.

Hope you understand, what i write about

hi,
make sure VCOM USB driver installed completely, flash tool will not recognize your device if VCOM USB not installed properly. open device manager on your computer while connecting your phone, but remember to turn off your phone before connecting. see pop up for 2 second on device manager, before disseppear right click it and point it to VCOM USB driver folder.

hi,
flash your device to android 4.2.2 first, then root it using framaroot. using root explorer simple delete or remove /nvram folder, reboot your phone then do change the IMEI using MTK droid tools.

hi,
if only root, i think you still can get OTA update, but if you already change lenovo standard recovery to custom then OTA update will just download but cannot update your system.

Reply to  Popescu Daniel

possible to remain without IMEI ?? are your IMEI already invalid ?? what you mean i don't understand. but if your IMEI already invalid i suggest not install 4.4, fix it by install 4.2 for easy rooting then fix your imei first, make backup then you can flashing 4.4

hi,
first we need check your IMEI dial *#06# and see if there is an IMEI, most Lenovo S850 problem is losing IMEI.
if your IMEI still there please try re-insert your SIM card, or change the slot of your SIM Card and then try to make dial or receive dial from that SIM
are you modified your ROM ?

If you don't ever modified the ROM and cannot received calls than just return the phone to seller it means there is something problem when you buying the phone. Then try to ask to the seller because you not modified everything but the phone already has that problem
