Common Misconceptions

  1. "Formatting all + download will fix it." – No. The efuse check happens before any partition is accessed. Formatting won't bypass hardware logic.
  2. "Re-locking the bootloader helps." – No. If the device is already bricked and won't boot, you cannot access fastboot to relock. Moreover, a locked bootloader does not disable the 0x146 check.
  3. "It's a virus." – No. This is a hardware security feature, not malware.
