How to Root Lenovo A820

Disclaimer: This rooting procedure has been noted to work with Lenovo A820 provided that the firmware version installed in Lenovo A820 is fit with the CWM version used in the tutorial. The CWM here works for firmware version S130 and S135. Owners with updated firmware versions like S138 and higher are free to try this method. However, we do not held liable for any loss of data or possible damage to your Lenovo A820. Worst case scenario is you might brick your device but that doesn't mean it's the end anyway. There are ways to unbrick a device and we're here to help you with that too.

We advise to those having higher firmware versions than S135 to use CWM v6.0.1.2
For those who will try our guide please read the instructions first and follow them carefully.

Rooting an MT6589 phone or tablet is almost always the same no matter what brand  the device is. One very convenient method is flashing a working RECOVERY first so you can easily flash or install the ROOT zip to your phone. Not only root zips but UPDATE zips as well and even ROMs.

                    How to Install Recovery to Lenovo A820
1. Download MT6589 drivers here. After download extract it using winrar/winzip then install to your PC. Sometimes for some reasons the MT6589 drivers won't work on some computers. If that happens please try to use the Universal ADB Driver. Get it here.
2. Download SP Flash tool here and extract it to your desktop. 
3. Download CWM v5.5.0.4 for Lenovo A820 S130 firmware here.
    CWM v6.0.1.2 for Lenovo A820 S135 download it here.
3. Run the SP Flash tool in PC and click "File" and select "Open scatter-loading file". Then browse for the scatter file (located in the CWM folder you downloaded).
4. Make sure all the lined boxes are unchecked except for the "RECOVERY" box. Above you can see a box for DA DL All With Check Sum. Tick that box.
5. Click "Download" or press F9.
6. Connect your Lenovo A820 (make sure it's turned off). If the flashing process won't start remove the battery of your phone and put it back after 5 seconds then connect it again to the USB cable. If flashing still won't start remove the battery and plugged in the cable without the battery.
7. The process should start after connecting the phone to PC and just wait for the process to finish. A green circle will come out after a successful flashing. Next is the actual rooting via Recovery Mode.

How to Root Lenovo A820 via Recovery
1. Download MTK6589-SuperSU-root here. Copy it to the root(not inside any folders) of your SD card.
2. Access the Recovery of your phone by long pressing the +volume button, -volume button and the power button for about 10 to 15 seconds. If it doesn't appear try to remove the battery first and put it back after 5 seconds then try long pressing again the +volume, -volume, and power button.
4. When you're at the Recovery Menu already use the volume controls to navigate up and down and use Power button to select or enter.
5. When you're at the Recovery menu select "Install zip from sd card" then "Choose zip from SD card" and look for MTK6589-SuperSU-root. Then select "OK".

Reboot your Lenovo A820 and you're done.
