I'm not sure what else you can try, then, at this point.
If you were able to get it into recovery mode (bootie), I'd say try zeroing out the master boot record, and then try tpdebrick again, but I think you said you can't get there, can you?
I had to do that on the 64GB TouchPad I revived, but I left it out of the thread because I wasn't sure if it was necessary, and I did it in a way that was wrong, so I didn't want to post bad information.
But if you can memboot your TouchPad, try zeroing out the MBR first - let me know if you need directions.
