do this at your own risk

You need a way to access the WebOS Linux terminal, so we can remove them.

download Novaterm, and launch that from your desktop PC. Alternatively you can use Xecutah local Linux terminal to run the commands below

i use noverterm my self just the way i like it not anyother reason i have done this both ways and it worked for me do this at your own risk

Check and remove partitions

Once you have a terminal open type lvm lvscan and press Return. This will list all of the existing partitions on the HP TouchPad, the three weâ€™re interested in are:

/dev/store/cm-system [304 MB]

/dev/store/cm-cache [200 MB]

/dev/store/cm-data [1.50 GB]

To remove each one type the following lines and press Return after each one:

lvremove /dev/store/cm-system

lvremove /dev/store/cm-cache

lvremove /dev/store/cm-data

back up your HP TouchPad, go to Settings > Backup and click Back Up Now. Once that done, restart the HP TouchPad and as it first powers up hold the Up Volume button and you should see the white USB logo. Connect the TouchPad to your desktop PC. make sure you have webdoctor for your hp touchpad

connected to pc start WebOS Doctor

Youll require Java installed and your HP WebOS account details, plus the device needs at least five percent charge. The entire reset process shouldt take more than half an hour.

Factory condition restoration Downgrade to webOS 3.0.0 and get back to 3.0.4

I. What you need

Novacom - Click

Novaterm - Click (or found in C:\Program Files\Palm, Inc\terminal. Run novaterm.bat)

Recovery uImage - Click

WebOS Doctor 3.0.0 - Click

WebOS Doctor 3.0.4 (optional) - Click

II. What to do

1) Install Novacom and extract Novaterm.

2) Open a command prompt and navigate to your Palm, Inc folder (usually \Program Files\Palm, Inc)

3) Move the recovery uImage to the Palm, Inc folder.

4) Boot your Touchpad into recovery (Power + Volume Up from power off)

5) In that command prompt, run ( novacom boot mem:// < nova-installer-image-topaz.uImage ) (without the parenthesis)

6) Once run, all you'll see on the Touchpad is the HP logo. This is good. Now open Novaterm and hit Connect

7) If you see a prompt that says something like "root@webOS device" this is good, now run these commands IN ORDER and these commands are CASE SENSITIVE

My pad is 32GB

mkdosfs -f 1 -s 64 /dev/store/media

8) When done, reboot the Touchpad into recovery (Power + Center/Home until screen off, then Power + Volume Up)

9) Run webOS Doctor 3.0.0 (This is to ensure a repartitioning and no other version will work at this point )

Branch 1) You can stop here to have 3.0.0 as your webOS version. You've just completed a downgrade that was before thought impossible.

Branch 2) If you want webOS 3.0.4, continue on.

10) When webOS Doctor is complete, hold down Power and Center, and when the screen turns off, immediately hold Power and Volume Up.

11) You'll see the USB icon again, just run webOS Doctor 3.0.4 and you're done.

just in case things go wacky.
