Mstarupgradebin New File

: Many "new" MStar builds (post-2017) have SECURE_BOOT enabled, meaning partitions like boot.img are encrypted with AES and signed with RSA keys, requiring specific decryption keys extracted from the device's bootloader to modify.

If your device uses SECURE_BOOT , older or modified MstarUpgrade.bin files will fail to flash. Always use official, manufacturer-signed firmware. mstarupgradebin new
