My lenovo s850 can't download any application in play store. How can i fix it ?
Hi,
More explaination please, cannot sownload because there is no play store or cannot download with error number? How about the connection, it is good or bad ?
Hi, can I get Google Apps when I upgrade S850 or do I need Root, TWRP and install from recovery? If so do you have links to software or can I use the S860 software and instructions that you have kindly posted?
Hi,
It depend what version that you install, lenovo have 2 kind of rom china version and international version. If you install international it already include google applications but not with china version. No you cannot use lenovo s860 software it will just brick your device so don't do it
Hi Andy, my apologies – the upgrade gives me all the GAPPs installed. Fantastic – great work!
Great… Happy for you too.
Thank you for visit
hallo, i need ROW_S210
sorry i don't have ROW_S210
Hi – When I connect the USB cable, the VCOM port comes on in Windows 7 Device Manager, but after 2 seconds the phone display activates and shows the "charging battery" indicator. At that moment the VCOM port disappears from Device Manager! There is no way to "turn the phone completely off" because the battery is not removable. What should I do?
Hi,
It can trust me, just need keep trying. Yes Lenovo s850 using nom removable battery but you can completely turn off and connect to computer for flashing. Remember to backup first before modified your device
Andy – I have tried it a hundred times. The phone _always_ goes to the charging mode when I connect the cable, and the port device _always_ disappears from the device manager at the same moment. Is there anything I could do to prevent this from happening?
Sorry there is nothing you can do beside try and try again. Turn off your device wait for second then connect your device. Try press volume up when connect it.
Hi Andy,
I got it working.
I now understand that if I plug in the phone with the Flash Tool not running, the phone will enter charging mode and the device will disappear from device manager.
But if I prepare Flash Tool for flashing, and only then connect the phone, it will not go to charging mode, and everything works fine. Thanks for your instructions!
Your welcome, thank you for visit
Andy: Also, after flashing the ROW_S211 rom, the phone automatically found and installed the latest update (ROW_S215 I think) as a very small OTA update, so apparently there is no need to manually install any updates after flashing it once.
My phone came with Chinese firmware (VIBEUI) but apparently the international firmware (ROW) works without any problems (I hope).
Goodjob for you and thank you for your visit, after successful update don't forget to do backup for your current ROM

i wanted to upgrade to the international row following your instruction to try it out
i thouth it's better first to make a backup of the phone prior to do anything but i dont know how to back it up ?
so haw can i back up the phone ?
Hi,
Yes i better to do backup first before modified your system, but full backup can be done only if your device is rooted, with out root you cannot do full backup, try rooting using root genius, towel root or anything that use one click method.
Becareful for modified Lenovo S850 once you lost your IMEI it will hard to restore the communication ability.

Hi,
Use this guide to backup your device http://bit.ly/1kcsUqj you can also need to backup your IMEI or NVRAM folder

Hi,
Above guude is about to install S211 on your device.
hello, andy my lenovo s850 does not have signal, did you know where can i get nvram for my lenovo?? or if you have nvram can you share with me?? pleaze….. : (
hi,
does not have signal often cause by invalid IMEI number on Lenovo phone, but for Lenovo S850 even you already restore the IMEI signal will never fix, until now i don't know what the problem and how to fix it. but for sure i know that we cannot use another phone NVRAM because it not same. and no i don't have and i will never give to other too because it will only brick the phone and not fix it.
for Lenovo S850 i just can recommend you to bring your device to Lenovo service center.
