Well, you do seem to have the G2 hboot on your DZ, and if you have a DZ ROM then I'm not too suprised if weird things are happening.
You may be able to flash the hboot itself via fastboot.
./gfree -s off
First of all im sorry if im posting this in the wrong area. I have read millions of pages on this forum and other and am really really confused. I have a Desire Z and it was running stock rom with the following details:
HBOOT - 0.76.2000 (PC1011000)
Since d rage method was not working for me initially due to ADB issues, i tried Visionary as an easy way out and now i seem to have semi-bricked my device as im always facing boot loop screen. I hadnt made any typos, everything was done as said. I have managed to get S-OFF and had enable USB Debugging before the perm root. However after this boot loop issue started, im unable to use ADB alongwith FASTBOOT as it doesnt list my device under attached devices on using ADB DEVICES command. Initially i also had a driver issue as it was detecting an android 1.0 device but i guess i solved that by using PDAnet drivers but still no success with ADB. I have never made any custom/ nandroid backups and im very confused as to what to do. I took my phone to HTC but since the 'z' is not yet launced here they said I would have to wait till the official launch (wtf).. is there any way to recover my device? i dont even mind using the old STOCK rom, i only wanted to root to enable 'trackpad wake' and 'overclocking'.. Please help me out folks
