    Big thank you. I bought an old Zenphone 2, and the official app to unlock the boot loader just forced closed. I attempted to follow several other instructions on the net, but they were outdated. These instructions worked like a charm. Now if I could just get Super SU working (reboots into recovery after flashing, but that's a different problem)

    It is not Recommended for ZE551KL But You Did. It's alright. Now All You have to Do is to Flash Your Stock OS to Your Mobile. Download Your Stock Firmware from Asus Site. But You Search in Google It will Get you to the Download Page. Then Extract Recovery from Your Stock ROM. Then Flash Your Recovery to Your Mobile from Fastboot Mode. Then Boot into Recovery Mode Then Select "Apply Update via ADB" Paste Stock Firmware to Your Platform Tool's Folder and Execute This Command."adb sideload " Then Wait until It's Done.

    Hi there, I dunno if my post earlier posted or something but the tutorial you made didn't work on me, I'm on Zenfone 2 (64GB/4GB RAM) running on MM, I ran the unlock.bat and it keeps saying waiting for connection 🙁
