Rooting and backing up the ROM on the Lenovo A850
Welcome to another tutorial. This time we’re starting things off with our first look at the Lenovo A850. And our first step is a very important one – backing up your current ROM before messing around with settings or experimenting with installing custom ROMs.
For this simple step-by-step guide, we’re going to be using a Lenovo A850 and various free apps to root the phone then simply install a custom recovery. This allows us to then make a nandroid backup of your complete system.
Before we start though, a disclaimer: by flashing a new recovery or using your phone with root access, you may be voiding your warranty. We take no responsibility if your phone is damaged or bricked by following these instructions.
Rooting the A850 is very simple. You don’t even need to download any files. Simply follow the link below to install Framaroot directly on your phone. You can then run it according to the instructions in the video. To check that the phone has been correctly rooted, use the Root Checker app. You can also use this to verify whether your phone is rooted if you’re not sure.
For backing up your ROM, you need to install a custom recovery which only works if your phone is rooted as above. Before you start, it’s easiest if you’ve already downloaded the recovery image you want to use and put it on your phone’s internal SD card. Just download it from the links below then unzipped them somewhere on your phone. You will then be ready to start following the instructions in the tutorial video.

hello I have Chinese recovery language in my phone I can’t able to read it will you please tell me that how can I change my language in English..
The menu order should be the same as standard Android recovery so if you google guides it will be the same. But better to flash a new one.
can i flash international rom (like row version) in lenovo chinese version firmware?
I’ve downloaded the recovery files and done installing mobileuncle but when I launch mobileuncle and clicked recovery there are tons of recovery image files I dont know which to click. help.

If you didn’t back it up it’s not possible.
Very interesting and satisfying.

It’s to make a backup in case you ever want to restore and go back.
Hey i am planning to root my lenovo A850 so that i can expand my internal storage. Firstly, I plan on using Framaroot. The question is will this root method can help me to expand my storage, let’s say if i used Link2Sd app. Help me please?
We recommend using this guide.

Should be fixed now?
thanks. it’s working now. Does it for A850 4gb? cause it’s bricked now…
Is that different from the normal A850?
not sure. but stuck at boot logo.
Can you get into recovery to restore your backup?
Sorry, it’s Mobile uncle tools for the Recovery Update. I tried both of the image files.. Please advise me of what went wrong as I’d followed exactly stated. Thank you.
After rooting with framaroot, I update cwm with image file thru uncle root.., but when it rebooted, it stuck at the Lenovo logo and off by itself. My specs are: A850, V13, Build Number : A850, S203, http://www.sjrom.cn. Any help is highly appreciated. Tx
Kindly forwarded to my email please.. Tx

hi admin,
i am using a Lenovo A850 and I would root and flash to a multilanguage ROM with Google apks.
I tried downloading the apks, recovery images, flash tools etc etc from the links you provided. But all are in exe format which i tried renaming but still in exe format. Could you please advice what exactly should I do?
Looking forward to your helpful reply.
