here is what I posted on another forum.. maybe it will help those having the 12% "tp brick" issue..
----------------------------------------------------------------------------
I am having the same problem. HP Touchpad Wi-Fi 32GB. Stuck at 12% and eventually the WebOS Doctor comes back with "We are not able to reset your device. Please go to HP Support for help." The link to HP Support takes you to a help page that doesn't help at all. Touchpad screen shows the processor with arrow pointing down on it. HELP!
Stupid for me to try and update using the WebOS Doctor. I had already updated via wi-fi to 3.0.2.
Anybody else figure this out. Any response from HP/Palm would be greatly appreciated.
******** UPDATE!! *****************
After spending 3+ hours surfing the web and probably trying WebOS doctor 20 more times, I finally have made some progress!
I read on other forums that the 12% is a specific percentage after wich the Novacom drivers kick in? or something like that. I thought that maybe the drivers that were downloaded with the Java file might not be adequete so I came across a site that had a link to the newest novacom drivers:
UniversalNovacomInstaller.jar - universal-novacom-installer - Universal Novacom Installer v1.2.1 - Universal Novacom Installer - Google Project Hosting...
After installing those drivers, I fired up WebOS Doctor, crossed my fingers as the progress bar went from 2%...4%..8%..9%..12%....13%!!then 21%... I couldn't look anymore and didn't want to be too excited because I've been there before, only to be dissapointed with the "Not able to reset your device" error....so I just opened up another browser and started surfing....after about 2 minutes, I cautiously looked back.. it was at 83%!.. before I knew what happend next, it was done and the touchpad was reboting into that HP logo and soon it was glowing and then the blue screen with the languages!! Yeah, I was that excited. Hope it works out for the rest of you... good luck!
FYI.. I was using Windows 7 x64... perhaps some issue with the TP 3.02 ROM and incorrect novacom drivers. The link above will recognize you have x64 Windows 7 and download appropriate drivers.. I think this is what made it work for me.
