Rezound won't power on or adb after Tachyon power-down topic






Hi everyone. I'll try to make a long story short while being thorough. Any help is much appreciated in advance.

TLDR Version: after messing around trying to get a working ROM and finally getting Tachyon 4.3.1 to load (without the SIM Card in), I powered down and the Rezound no longer powers on in any mode nor is it registered by adb. LED lights up while plugged in, that's it.

Complete version:
I spent a few days reading up on rooting & ROMing - but apparently not long enough - then spent an arduous night attempting to get a working ROM on my Rezound. I initially used AmonRa to get RezROM EX 3.4 to load up, but was stymied by constant "com.android.phone has stopped working" messages. After attempting several fixes, I formatted all back to Ext 3, and wiped the phone to factory settings (I know, I know...) in an attempt to start fresh. After that sloppy attempt, the phone wouldn't get past the initial white HTC screen, so I did the following using less than stellar judgment: I removed the Verizon SIM Card, rebooted, and installed Tachyon 4.3.1 (linked at bottom) in AmonRa recovery. Miraculously, I thought, the phone loaded up Tachyon and after one "com.android.phone has stopped working" message, I was able to use the phone, albeit with no network connection. I thought all I had to do was power down, put in the SIM Card, and maybe things would be alright.
Instead, what happened was this: I powered down, took out the battery (which had some charge) and put the SIM Card in. When I pressed the power button back on, the phone did not turn on. Unplugged, not even the LED would light up. I plugged it into my PC, at which point the LED does turn on, but pressing power only causes the buttons on the bottom portion of the phone to light up for a few seconds. That's it. The screen does not do anything. Holding Volume Down + Power does the same thing; it does not vibrate or boot to Recovery. Lastly, adb no longer registers the phone's presence (error: device not found). I plug it in the USB, hear the chime, but commands like adb list, adb reboot, etc. do nothing. The phone appears as an external drive in Explorer, but it cannot be opened. I've now tried two batteries and let the phone charge for a few hours. Still no results.

If I've bricked the phone, I understand. I fortunately have another Rezound I can fall back on. I understand the risk of taking the unresponsive phone to the Verizon store, so I'm asking for help/suggestions here. Thanks!
