So when I first attempted the Veer update from webOS 2.1.2 to webOS 2.2.4 I did it thru command line...
It went fine, then I got a hardware replacement from HP/Palm...

Did it all over thru command line and when it ran PmTPUpdater, it failed...

The TP rom got corrupt and the panel ID was erased...
As the PmTpUpdater just calls catnip it assumes things are good... Once they are broke PmTPUpdater will no longer work...

So I had to use catnip to fix it... catnip is not a toy... it is very technical if you do not know what you are doing then do not do it...

It does not seem to be as bad as A6 firmware, but if your Touchpanel is broke, it can be fixed... I have only had Veer TouchPanel issues, but this tool is on all devices...

PmTpUpdater is a script that calls catnip...

To fix a panel ID for instance one would

/sbin/stop hidd
/usr/bin/catnip resume
/usr/bin/catnip pid "pid id"
/usr/bin/catnip suspend
/sbin/start hidd

I was able to get my TouchPad Go working again this morning with the help of John Steffes. Huge thanks to him and all others who assisted me.
