Bringing back the DEAD topic. CHuvaCK21 are you still home? I hope so..

ANyway I am wondering if your method of unlocking the ZE500CL could be applied to my device the Asus TX201LA. Its has the same soc z2560 cpu and the droidboot version is the same 2.0. The IFIW is slightly different and I wonder if I sent you the files could you apply the same unlock trick you did on the droidboot files to my TX201LA files? I hope I hear from you. Otherwise Ill try to reverse engineer your trick. Unlikely I get it since I'm NOOBtastic. PLEASE REVIVE your old thread.. Hope you can answer. Ill also PM you. THX

I ran this utility and the phone boots with white screen. It seemed unlocked. After that i flashed twrp (fastboot.exe flash recovery twrp.img) and reboot to recovery, it's still asus' recovery menu instead of twrp. :-(
