The so-called “Failed to Mount Partition” error is a very common challenge users face with TWRP (Team Win Recovery Project). This generally arises when trying to either flash a custom ROM, wipe a partition, or back up some data. Red screen messages often cover the screen-red alerts, which pose a sense of urgency.

What Could Cause the Trouble?

The possible causes of this error include:

  • Partition Corruption: The specific partition may be corrupted and TWRP cannot access it.
  • Unsupported Filesystem: If the filesystem of a partition is not supported or is not being recognized by TWRP accurately, the booting may fail.
  • Older Version or Incompatible TWRP Version: Running an older version of TWRP that your device is not compatible with may also fall in line with this error.
  • Partition Needs Reformatting: Sometimes a partition may just need reformatting after flashing a particular ROM.

Step 1: Confirmation of Success of Operations

Before you further delve into fixes, check whether the error affects normal working. If TWRP shows a “Successful” message after flashing, the “Failed to Mount” message could be a false positive, or it could be harmless. Here’s what to do:

  • Confirm Success Message: If you see the message “Successful” on the top bar of TWRP, then, the flashing is probably working. You can then proceed to format data and reboot the device into the system.
  • Ignore It: Often you can just ignore the error if it doesn’t prevent you from doing other things. But in some rare occurrences, this can persistently intrude into your life.

Step 2: Update TWRP to its Latest Version

Older versions of TWRP may not support newer filesystems or partition layouts. Update TWRP to the latest version often, times solving one of its problems.

  • Download the Latest TWRP-Go to the official TWRP website and download the version compatible with your device.

  fastboot flash recovery twrp.img

  fastboot reboot

Make sure the new version of TWRP loads correctly.

Step 3: Reformat the Problematic Partition

  1. Go to Wipe: Boot into TWRP and select Wipe> Advanced Wipe.

  3. Repair or Change a File System: Try clicking on Repair first. If it doesn’t work, press Change File System.
  4. Format to ext4: Select ext4 as your filesystem and confirm. After this, switch back to F2FS if necessary.

Step 4: Repair Partition via ADB

If TWRP is unable to repair the partition, sometimes ADB commands would allow the problem to be resolved.

  • Connect Device to PC: Ensure ADB is set up on your computer, then connect your device.
  • Use ADB to Repair:
  adb shell
  e2fsck /dev/block/mmcblk0pX

Replacing mmcblk0pX This means implementing the specific identifier of the partition. This command will not only check but also try to repair any corruption in that partition.

Step 5: Change Partition Filesystem in TWRP

If a particular filesystem is having issues, it would be prudent to convert it to a more compatible one.

  • Advanced Wipe > Change File System: In Advanced Wipe, select Change File System.
  • Choose ext4 or F2FS: Here, format ext4 or F2FS depending on the compatible devices; that will help if the present filesystem is not supported by TWRP.
