    The touchscreen on my touchpad stopped working. HP is sending me a box to get it fixed. I ran ACMEUninstaller to get rid of Android and then WebOS Doctor, but how do I delete the Lost Dir. folder etc. to make sure everything is wiped?

    I can get the Touchpad into the USB logo screen, but it doesn't appear on my computer when I plug it in.

    Do you mean the sdcard?

    You might need to wipe the sdcard partition via adb.

    Sorry, I'm not fluent in adb.

    I DO know this much...

    Open command window...
    adb devices

    After that it gets foggy. :D

    How to erase your touchpad USB drive:

    First put the device into recovery mode, then memboot the device using the installer uImage (extracted from your webOS Doctor jar):
    novacom boot mem:// < nova-installer-image-topaz.uImage

    After it boots, run novaterm:
    novaterm

    Once connected to the device, type:
    lvm.static vgscan --ignorelockingfailure
    lvm.static vgchange -ay --ignorelockingfailure

    then type:
    mkdosfs -f 1 -s 64 /dev/store/media

    Once that completes, put the device back into recovery mode and run the webOS Doctor.

    Yes, it's on it's way back to HP.

    I'd be interested in how it works out for you (having had Android on it at one time).

    Was it much work? Any hurdles?

    Nope, the only trouble was figuring out how to wipe via command line.

    I was reading on Rootzwiki last night where someone's TP wouldn't charge and he had to return it to HP for repair. They refused warranty and wanted to charge $265, b/c they found it had Android on it.

    Well, then I am really glad that I took the time to completely format the disk with the computer!
