TWRP Update wrong partition

Assuming you have fastboot installed on your computer (or for Win/Mac you could use the version bundled with the install package):

  1. Download the manual install package for the version of the OS you’re using to your computer (match the version number to what you have installed - if its an older version, you can find the link here).
  2. Extract the install package.
  3. Find the path to boot partition image file in the extracted files (usualy boot.img under images.
  4. Connect the phone to the computer with a USB data cable and start the phone in fastboot mode.
  5. On the computer run fastboot flash boot [imagefile] in a terminal, where [imagefile] is the path to the image file you found in step 3. On linux systems you may need to use sudo for this step.
  6. Reboot the phone.
