How to toast a micro controller

  1. Short peripheral chip by applying the wrong voltage to either one of its inputs
  2. Connect the shorted chip to your micro controllers power outputs, effectively shorting it too

Lesson: Don’t mess with micro controllers in the middle of the night, especially not when you’re tired and lazy.

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 ..).
