Bootloader Relocked, no longer unlockable
i've got a Problem with my C6903.
Yesterday i unlocked the Bootloader of the Z1. (No TA Backup was made
). Today i Relocked the Bootloader with Flashtool, because there where no usable Custom Roms available. But then i thought why not try some different Kernels?! And now here's the Problem:
I can't Re-unlock the Bootloader. The Fastboot Command says when the first Time entered: Command did not succed. The second Time i enter it it say Device already rooted. Then i'm able to boot from a custom Kernel, boot to CWM and install AOSP Rom. But after Restart the Screen goes Blank (like Locked Bootloader). Flashing a Rom/Kernel through Fastboot just says Command not allowed. In Flashtool, i'm able to Unlock/Relock the Bootloader, well the Tool still says after Unlocking Rootable
, not Rooted
. But also after unlocking in Flashtool the Problems resist. Tried Flashing Stock Rom with Flashtool, with PC Companion(Repair) but no succes. Service Menu still means Bootloader Unlock allowed: Yes.
Would be nice if you Guys could help me out
