view story

http://forum.xda-developers.com – Hi guys I kinda stuck here. I tried to Unlock and flash my HTC Desire HD but I think something went really wrong. Here's my actual status: I unlocked my Bootloader using HTCDev to flash the 4EXT Recovery After unlocking in I tried the Ace Advanced Hack Kit (also with a re-locked Bootloader as suggested on the webpage) but it never worked for some reasons all the PD98IMG.zip seem not to be applied on my device, they get parsed by the HBOOT but I never get a "Install?" question ACE PVT SHIP S-ON RL HBOOT-2.00.0029 RADIO- 4EXT Recovery is installed and I can access it (HowTos)
