How to unlock a re-locked ONE Developer edition?

[LenFari]

Hello everybody,

HELP PLEASE!

I flashed my dev ONE to Android Revolution HD 12.1 yesterday, but the APN won't work for my Metro PCS LTE, so I just flash back to the stock via RUU as this post http://forum.xda-developers.com/show....php?t=2265618 instructed, method 2.

Now, I copied the APN setting, and want to switch back to Android Revolution HD 12.1, but the tragedy happened, the bootlooter changed into relocked, and I cannot unlock it anymore.

Please help.

Thank you very much!

Regards,
Vince

What method are you trying to unlock the boot loader using? If it is the HTCDev one, you'll have to go through the whole process again since the Unlock_code.bin you used before is no longer valid and you'll need to get a new one and flash it.

Hi TarekElsakka. thank you very much. Yes, I found the reason, I tried the whole process at first but it said the token is invalid one on htcdv. Then I just reboot it, try again, it works, and unlock now.

Thanks again!
