Hello Hovatek Team,I am following up on your email recommendation. I am trying to unlock the bootloader of my itel A70 (Model: itel A665L).As mentioned, the device is running on the Unisoc T603 chipset with the latest January 5, 2026 security patch level (Android 13, Build: A665L-SE673SBCEFHJKBMNOPQRSTUVWX-TGo-OP-260116V1...).The standard Python script tool (unisoc-unlock) fails with the "Unlock bootloader fail" error when trying to flash the signature file. However, I am still able to successfully extract my Identifier Token via fastboot.Here is my extracted Identifier Token:313132393031353334244303033313332Since the traditional signature.bin token method is not supported due to the 2026 security update, could you please guide me through the alternative approach or tools (such as modified Research Download / Upgrade tools or custom loaders) to bypass the bootloader protection on this specific firmware version? My ultimate goal is to root the device.Thank you very much for your continuous support!
