[Q] XE bootloop after installing RUU, cannot downgrade or unlock bootloader or S-OFF
This is a little complicated. I have an XE and I wanted to upgrade from 2.3 (HBOOT 1.18). I tried to S-OFF first with revolutionary, but it didn't work (not even with tacoroot). Then I wanted to unlock the bootloader with the HTCDev method, I have the Unlock_code, uploaded it with fastboot and then selected yes. The phone reboots but it's still LOCKED. I repeated a few times, but no success.
I thought, OK the stock ROM by HTC is enough. I installed 4.0 with the newest RUU (HBOOT 1.29). This is where the bad things started. The installer worked well, but I couldn't start my phone anymore. It is stucked in bootloop. I tried to downgrade (with RUU and flashing zip with fastboot), no success.
So: S-ON, locked bootloader, bootloop... what could I do? Oh and when I plug in the USB cable, the phone turns on by itself.
Please help! Thank you!
