[Thunderbolt Q&A, Help & Troubleshooting] muddydog4:
Hey guys. I rooted my thunderbolt, and put the Liquid-ICS-v1.5-MR3-Mecha rom and the clockworkmod with touch recovery on it. All was great for the first day, second day while listening to music my music stopped and my phone could no longer see my 32gb sd card. I powered off, and reseated the sd card. Booted back up and i was able to listen to music again, for about 5 minutes, then same thing. I blew out the port with air duster and tried it again, it worked for a bit longer, but alas, it happened again. After the 4th try it could no longer read my sd card. I have an upgrade in march so i figured ill deal with it. About a week later my phone started rebooting alot. I never installed anything other than angry birds and Google play music so i could listen to my backed up music once my sd card stopped working. After about a day of rebooting randomly, it finally went into a bootloop, not getting passed the white screen. I could sometimes pull the battery and turn it back on and it would boot normally. After a while i wasn't even able to do that, so i booted into recovery, which also couldnt mount my sdcard, and wiped data, cache and dalvick. My phone booted up into liquid and I had to re set everything back up. After rebooting it, it went back to the bootloop problems. I then wiped everything again, this time wiping system as well. Nothing booted up after that past the white htc screen. I could still get into hboot and recovery though. hboot also couldnt load the sdcard when i put nothing but PG05img.zip for some reason. never found it, always came up with an error. But it would say it was trying to load pg05diag.zip instead. tried naming the zips as that too, but that didnt work either. Tried using adb to push a new rom but it would error out. Used fastboot to flash different recoveries hoping one would be able to read my sd card and i could flash a new rom. None worked, tried amon ra, twrp, and the non touch cwm. so I tried following a return to stock guide, using the tbolt.zip. that seemed promising, but I couldnt flash a new rom. My phone seemed unable to work with it. I managed to get rid of revolutionary, was still s-off, and still had amon ra. So i tried returning to stock using some .exe ruu's. but all get stuck at 56% updating the system. but I am now left with this screen:

MECHA XD SHIP S-ON

HBOOT-1.03.0000

RUU

I can also get the black htc screen with the 4 white triangles in the corners.

I have searched and searched and followed every guide I believed would fix it.

But at this point I believe it is bricked. Those 2 screens are all I can get to. Any help would be greatly appreciated

EDIT. I can re-lock and unlock via the HTC dev tool, but thats about it. I have used to the most up to date ruu I can find and even the oldest, when I run the ruu the wizard shows no previous version. They all get stuck at Updating system at 56%. The only way I can get to the ruu/hboot screen is to turn my phone on, plug it into the computer and then un plug it. I cant flash an zips, cant ADB, fastboot is very slim on what I can do. I have tried everything I can find. I will probably be using my insurance to get a new phone this weekend til I can upgrade, just wondering if There was any last ditch option I could try.
