Trust me - it's really really hard to brick the Touchpad. I thought I had at one point, ok 3 points.
Rebuilding all the partitions works miracles.
If you give me what you've done, how you got to where you are - I can help you unbrick it... keep the 15.
PM me and we can work out a time to get you straight.
*MT4G running whatever ROM I feel like at the moment, but probably MIUI
*HP Touchpad running XRON-ICS or CM9 back and forth.
*iPhone 3G jailbroken and used as a fancy remote for other things
*Dash 3G running some ROM from somewhere, mostly used as a mobile hotspot.
