FramaRoot is one method that you can do straight from your phone without the need for a PC to assist, and is simple enough to use. However, just like any rooting procedure there are a few steps to take to make sure you don’t end up with a new paperweight.

Before going further let me tell you the most important thing first – Rooting Voids Warranty . Once you root your device you can unroot it anytime.

Method 1: Root Lenovo S820 With Framaroot

  1. Download the latest version of Framaroot and install the APK.
  2. Now, Open Framaroot select the action to perform. Select “Install SuperSU”.

  3. Thereafter, in the rooting menu, Select an exploit in list above to potentially root your device as BOROMIR and proceed further. The rooting has now started and you will be getting an awesome success message.

  4. After the process and after restart , you will see the root permission granter app , i.e SuperUser app (SU app).

Method 2: Root With Kingroot

  1. Before installing kingroot, you have to disable the internet on the phone first
  2. Open the APK file with your default file manager
  3. If your device displays Installation Blocked or something like this message then Go To SettingSecurity and there you can tick the Unknown sources box.
  4. When the installation is complete, enable again your mobile internet
  5. Click “try root” button to start rooting
  6. If your device is compatible, it will finish rooting after few minutes. If rooted successfully, you will see rooted screen which means you device has been successfully rooted.
  7. To become more sure, you can go to google play, search and download Root Checker app to Check if the Root is successful.

  1. Thanks for this usefull article,

    but I have two questions:
    – can I get an official OTA update after rooting?
    – can I increase the enternal memory by decreasing the USB memory?

  2. I have a lenovo s820, and following your instruction i successfully rooted the phone. Unfortunately a few days later the phone upgraded to this viberom thing and now I am no longer able to root the phone with framaroot app. Please can you help me solve this problem ???? I am going crazy!!!!

  3. I have same problem- i have s820 with latest vibe rom viberom_v1.0_1347_3_st_s820, and rooting with framaroot is not possible- I get the success message, but after restart phone is not rooted. is there any other way to root this phone?

  4. the history of this apl can read on http://www.xda-developers.com or :
    Version 1.8.1: Another attempt to fix crashes.
    Version 1.8.0: Add Faramir exploit, little brother of Boromir (potentially affect Mediatek based devices).
    Version 1.7.1: Link to Framaroot donation added (it does nothing as this kind of application are forbidden on play store … but it could do something someday)
    Version 1.7.0: Due to a mistake, Pippin exploit didn't appear in exploit list, its fixed now (Huawei device owners welcome). Add Gollum exploit for AMLogic based devices.
    Version 1.6.1: Remove Superuser as it fail to install. Add execution support from adb command line.
    Version 1.6.0: Add Pippin exploit (potentially affect Huawei K3V2 based devices)
    Version 1.5.3: An attempt to fix Gandalf error#10
    Version 1.5.2: Revert to exploitation fix included in 1.4.1. Add Slovakian and Italian languages. Error # added in toast message when exploit failed (report the error number in this thread so I could give you the reason of failure). Previously fix for Framaroot crash was a dirty hack, with this version you shouldn't encounter crash.
    Version 1.5.1: Should fix Framaroot crashes.
    Version 1.5.0: Add Boromir exploit (potentially affect many Mediatek based devices).
    Version 1.4.3: Update SuperSU to 1.34. Rewrote the fix include in 1.4.1 for better but slower exploitation.
    Version 1.4.2: Add Russian and French languages. Add scrollbar for exploit list. Update SuperSU to 1.30
    Version 1.4.1: Fix a bug in exploitation due to the different kernel data alignement between version and devices, so if exploits didn't work before it "may" work with this version if your device is vulnerable
    Version 1.4: Add Gandalf exploit (potentially affect Qualcomm based devices, tested on Nexus 4, as always feedbacks are welcome)
    Version 1.3: Add Aragorn and Legolas exploits (could affect wide range of samsung devices including non exynos devices, please give feedbacks for your devices. Thanks)
    Version 1.2.1: Fix unroot bug. Improvements for exploitation. Embed SuperSU 1.25
    Version 1.2: Add possibility to Install Superuser, Install SuperSU and Unroot
    Version 1.1: Frodo exploit added
    Version 1.0: Initial release
