I'll install this once theres an easier way to completely wipe the whole thing back to stock, including partitions.
There is, it takes less than 1 minute of typing and 10-25 mins for WebOS Doctor to do it's thing.
Here's what I did:
Boot to WebOS (I'll assume you have preware installed on the TP). Look for a program called Xecutah, it's a client side terminal. Fire it up and type:
lvm lvscan
and it will show you all the partitions. The ones you want to remove are CM-Data, CM-system, CM-Cache.
To do that, at the terminal prompt, type:
Lvremove /dev/store/cm-system
Lvremove /dev/store/cm-cache
Lvremove /dev/store/cm-data
Reboot the device whilst holding the volume up key to get the white USB icon. Attach the TP to the PC.
Download WebOs Doctor and let it do it’s thing
Remove any old .android folders by mounting the TP to the PC.
I didn't back my TP up before I did this, and all the local media has gone. However, as far as applications go, it just goes off to the market and installs all your apps in the background. I had to re "preware" and kernel the unit again too.
