Having issues mounting data on TWRP recovery? Well, the most likely reason for that is encrypted data on your device. Manufacturers have been selling Android devices lately with forced encryption enabled (for safety of your data). This makes certain versions of TWRP not able to mount data partition on the device, and hence unable to flash a zip file (like SuperSU) from TWRP.

Generally, flashing SuperSU zip using TWRP’s install menu is the easiest thing in the world. But if you’re having issues mounting data partition of device on TWRP recovery, then it’s impossible to use the Install button on TWRP to flash a zip file. In that case, you can use the ADB sideload option.

While stock recovery only allows flashing signed zips from ADB sideload, you can install/flash an unsigned zip as well in TWRP recovery via ADB sideload command. And that’s how we’ll flash the SuperSU zip via ADB sideload.
