How to enter flash mode
Your bootloader must be unlocked using amonet.
The exploit remaps the volume buttons to switch between boot modes, so with it installed you can use them to select different boot options:
- HACKED FASTBOOT mode: Access this mode by holding ONLY the Volume Down key after connecting the power source.
- TWRP / RECOVERY mode: Enter this mode by holding ONLY the Volume Up key and the after connecting the power source.
- PWNED USBDL mode: Enter this mode by holding ONLY the MUTE and VOLUME DOWN buttons while connecting the power source. The USB cable MUST also be connected.
You can also use the boot-recovery.sh and boot-fastboot.sh scripts to force either mode if the buttons aren't available.
In PWNED USBDL mode, you can use tools like MTKClient to flash the device. It is important that you NEVER modify LK, TEE1, or Preloader, as they are required for the exploit to function.
You can boot OSS bootloaders by flashing them to the expdb partition and OSS ATF by flashing it to the TEE2 partition.
