MTK_Unlock

Unlock bootloader via WebUSB using the r1_escape method: kamakiri2 exploit → FRP modification → fastboot unlock.

1. Enter BROM Mode:

  1. Power off R1 completely (hold power ~10 seconds)
  2. Connect USB cable to computer while device is off
  3. Hold power button for 3-5 seconds — do not let go yet
  4. "MT65xx Preloader" appears in the WebUSB picker

2. What This Does:

  1. Kamakiri2 exploit bypasses BROM security (CDC overflow)
  2. Uploads Download Agent for flash access
  3. Reads FRP partition, sets unlock flag byte
  4. Reboots to fastboot — then click CONNECT_BOOTLOADER above
