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

Reply to  simon warner

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.

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

Reply to  Online GPS

Hi,
To root lenovo s850 we need to install custom recovery first then install root from that custom recovery. But lenovo s850 have bugged custom recovery so it have difficult to install root access from it, so it need to wait the new update for the custom recovery before we can root it again. This is the guide for root http://bit.ly/1uoax6K and this is the guide for custom recovery http://bit.ly/1qzuyp8

hi,
are you make backup your previous ROM? touch screen not function is the main problem for Lenovo S850 beside missing IMEI and Signal problem.
for now i just can recommended you to try flashing another ROM until you found which ROM that fix touch screen problems, but remember be careful for missing IMEI

if you ask me, i cannot make decision, it all up to you.
cannot play video, what error? have you tried 3rd party video player?
of course system updates will fix the old rom bug but cannot play video i think it not a bug try factory reset or remove cache and data on your video player.
becareful on update Lenovo S850 a lot people suffer signal lost after update

i've tried using dolphin, chrome and mozilla browser but still cant play flash video. The video wouldnt plug in. Factory reset will not change the current updates is it? My s850 now is on row_s119.

androidrookies

playing video on browser ??
it using flash plug in, it need you to install flash plug in.
that not have any related with ROM though you change your ROM thousand times it will not fix the problem.
search android, flash, video plugin in on google and you will see how to

hi,first i will tell you that before doing any modified you must backup all system file, especially NVRAM partition, this partition contains all files that have relationship with communication and IMEI, this NVRAM is not replaceable so cannot use another NVRAM device or else.when you wrong upgrade or modified device it erase NVRAM flder and partition so you device lost capability to communication that why you got no service and when you dial *#06# it will show you invalid IMEI mean you IMEI lost.for another device except S850 we can restore it by re flashing stock ROM to our device… Read more »
