How to brick your Android phone

Steps:

  1. Make sure your phone is encrypted
  2. Unlock the bootloader (OEM unlocking)
  3. Erase user-data partition

Not enough! Your device seems bricked, but since you can enter recovery mode it can be saved by reformatting the filesystem (ext2 -> ext4, repair system).

To actually brick your device:

  1. Boot your phone into fastboot mode
  2. Make sure the bootloader is unlocked
  3. With the fastboot command flash a new boot.img to the boot partition
  4. Done

Interesting facts about Android:

  • When unlocking the bootloader all your data gets wiped
  • Does not let you downgrade to older firmware versions

Also don’t ever rely on the Google backup function:

  • Google backups can only be restored on initial system setup
  • Google backups don’t contain any app data (so what’s the point of this backup?)
  • Google will sync your phone contacts into your Google account, the contacts you backed up can not be restored otherwise
  • System settings are all lost even if you backed them up

Instead, backup your data using OEM tools (OnePlus Clone, Samsung whatever ..).
