Okay, I was given this Bricked Acer 500 with the information that it was bricked "while rooting it". That's all of the original history I had.
It boots to the Acer logo, and no further.
When I first got it, I attempted to use the SD Card / update.zip technique to unbrick it. The first time, it got about 20% through, then stopped progressing, frozen for several hours. Retrying, it would go the the Dead Android without even loading the progress bar.
I was able to retrieve the CUID via Linux.
Attempting PBJ20upgrade (or DotNetDetector directly) from the root-3.2.1 package resulted in freezing at about 10% or so. Blackthund3r's APXFlash (packages 1 and 16) failed as well - it would set it into the state where APX Downloader was displayed at the upper right, then the next nvflash window would open and just sit there while "uploading" with no progress (even overnight).
Going back to the linux box (as per http://forum.xda-developers.com/show....php?t=1579490
), I attempted to manually nvflash, as per the following:
./nvflash --bct flash.bct --setbct --configfile flash.cfg --create --odmdata 0xb00d8011 --bl bootloader.bin --sbk 0x2CA41E00 0xD489E106 0x3BC00504 0xD8292103 --go
It ran, but failed with the following information:
bootloader.bin sent successfully
waiting for bootloader to initialize

So far, the only post I've seen addressing this suggested the novel approach of baking the tablet at 200 degrees for 20 minutes!
Any better plans than baking the tablet would be appreciated.
