How to Use the WebOS Doctor on the HP TouchPad (Upgrade/Downgrade/Fix WebOS)
61How and when to Use the WebOS Doctor on the HP TouchPad
Q: What's the WebOS Doctor and when should I use it?
The WebOS Doctor is a program that has two main functions for HP TouchPad users. It can either upgrade/downgrade your version of WebOS or fix problems with a damaged WebOS by completely reinstalling it. If WebOS no longer boots or apps and preware have stopped working correctly, then you will need to resinstall WebOS with the Doctor. A failed or interrupted attempt at changing the partition sizes with WebOS preware app Tailor may cause these problems. To check what version of WebOS is currently installed go to Launcher(Up Arrow)/Settings/Device Info/ Version
Note(Important): You MUST uninstall Android before running the WebOS doctor. Failing to remove Android before running the Doctor can result in the process becoming stuck at 8-12% and potentially bricking the device. If you are currently stuck visit the thread below for information about fixing the problem. If you're unable to use the tablet at all follow the instructions in Jcsullins TPDebrick thread.

Note(Important): Running the Doctor will completely wipe all personal information, applications and preware from the TouchPad. Media like music and movies will not be affected. However I would recommend backing your important files to PC, before running the Doctor.
Note(Important): In order to install apps from the WebOS store you will need to get the Root Certificate fix for WebOS cloud services.
