+# TWRP (Custom Recovery)
+
+> [!NOTE]
+> Not tested yet, we need to unlock the bootloader to boot TWRP
+
+[TWRP repository link](https://github.com/moto-penangf/twrp)
+
+When trying to flash via flash tool / mtkclient it gives Red State error and goes into bootloop. There is access during this error only to fastboot, recovery and normal mode is not available.
+
+**Looks like we need to unlock the bootloader to test this.**
