[TouchPad Development] MikeCriggs:
ATTENTION!

This guide is outdated and I can no longer support it as I no longer own an HP Touchpad.

Disclaimer:

This WILL void your warranty.

I am not responsible for mistakes, typos, bricked devices, or any problems you may encounter. You have been warned.

You will most likely brick your device if you aren't very familiar with Linux file systems and advanced UNIX CLI.

Follow steps PRECISELY.

Back up your files, you WILL lose everything you have on your Touchpad.

Please, be very careful.

I no longer own an HP Touchpad, so please help each other with issues.

What Works

WiFi

Bluetooth

USB Host (via OTG and Y-Cable Solution)

It's pretty much stable and very useable

What Doesn't Work/Some Bugs

Camera

Microphone

Audio

Unity is laggy (I suggest Gnome Classic or LXDE)

Mouse pointer disappears sometimes

Part 1 (WebOS)

FYI: How to enter Developer Mode In the "Just type..." text field at the home screen, type "webos20090606". In the results, there will be an icon labeled "Developer Mode". Select this, do not enter a password, and turn on Developer Mode.

A. Turn on Touchpad and connect to PC via USB

B. Open WebOS Doctor 3.0.0 and allow to run to 8%

C. Kill WebOS Doctor

D. Open Novaterm (Linux/OSX, simply type "novaterm" into a terminal window. Windows, navigate to C:\Program Files\Palm, Inc\Terminal\novaterm [it's a Windows Batch File], now press CTRL+SHIFT+C and hit enter to connect to the device [Windows only])

E. You should now be in a bash shell. Enter the following commands (one by one) to manually recreate the device partition scheme:

lvm.static vgscan --ignorelockingfailure
lvm.static vgchange -ay --ignorelockingfailure
lvm.static vgremove store
lvm.static vgscan --ignorelockingfailure
lvm.static vgchange -ay --ignorelockingfailure
lvm.static vgcreate -s 8M store /dev/mmcblk0p14
lvm.static vgscan --ignorelockingfailure
lvm.static vgchange -ay --ignorelockingfailure
lvm.static lvcreate -l 71 -M y --major 254 --minor 0 -n root store
lvm.static lvcreate -l 8 -M y --major 254 --minor 1 -n var store
lvm.static lvcreate -l 2 -M y --major 254 --minor 2 -n update store
lvm.static lvcreate -l 3 -M y --major 254 --minor 3 -n log store
lvm.static lvcreate -l 32 -M y --major 254 --minor 4 -n mojodb store
lvm.static lvcreate -l 17 -M y --major 254 --minor 5 -n filecache store
lvm.static lvcreate -l 64 -M y --major 254 --minor 7 -n swap store
lvm.static vgscan --ignorelockingfailure
lvm.static vgchange -ay --ignorelockingfailure

This command will display information about the Volume Group: store. At the bottom you will see "Free PE/SIZE X / XX" (where "X" is your own value). Please take note of the "Free PE" value.

lvm.static vgdisplay

Replace the "X" in the first command with the value you took note of in the previous command.

lvm.static lvcreate -l X -M y --major 254 --minor 6 -n media store
lvm.static vgscan --ignorelockingfailure
lvm.static vgchange -ay --ignorelockingfailure
mkdosfs -f 1 -s 64 -F 32 /dev/store/media

F. Run WebOS Doctor 3.0.0, allow it to complete and reboot into the language selection screen.

G. Power down the Touchpad by holding the Home and Power buttons simultaneously.

H. Boot into WebOS Recovery Mode by holding down the Volume Up and Power buttons simultaneously until a USB logo appears on the screen.

I. Run WebOS Doctor 3.0.5

J. Set up WebOS as you normally would

Part 2 (Ubuntu)

A. Mount USB Drive mode

B. Copy files from the prerequisite section of this guide into the root folder of the device.

C. Unmount/eject device

D. Enable Developer Mode (webos20090606 in "Just type...")

E. Open Novaterm again

F. Enter the following commands (one at a time):

This will create a 4GB partition for Ubuntu. Your device will reboot afterward, make sure it ends up back into WebOS with Developer Mode enabled again.

cd /media/internal
cp 4GBPartition.sh /tmp
cd /tmp
sh 4GBPartition.sh

This will install Ubuntu and the Moboot Bootloader. After install has completed, your device will reboot into Moboot, select "Ubuntu" to boot into Ubuntu and finish setup.

cd /media/internal
cp 4GBUbuntuInstallSystem.sh /tmp
cd /tmp
sh 4GBUbuntuInstallSystem.sh

Once you reach the Ubuntu log in screen, click on the universal access icon in the top right-hand corner and select On-Board keyboard. Type in the password "ubuntu". Once booted into Unity, click the dash home and browse through installed applications (opening On-Board and Terminal). Type the following into the terminal to enable Bluetooth and Wifi (sudo password is "ubuntu"):

sudo depmod -a
sudo gedit /etc/modules

Now a Gedit text editor window has opened. Add "ath6kl" to the bottom, save, and close. Go back to the terminal and type the following:

sudo update-rc.d bcattach_srv defaults
sudo reboot

Part 3 (Android)

A. Boot into WebOS

B. Connect via USB and enable USB Drive mode

C. Create a folder called "cminstall" in the root of the device

D. Copy all files from the Android prerequisite section into "cminstall"

E. Unmount/eject device

F. Enable developer mode (webos20090606 in "Just type...")

G. Open Novaterm

H. If in Windows, please copy the "ACMEInstaller2" file to "C:\Program Files\Palm, Inc\Terminal"

I. If in Windows, open a terminal and type the following commands in one line at a time:

cd 'C:\Program Files\Palm, Inc\Terminal'
novacom boot mem:// < ACMEInstaller2

J. If you are in Linux, simply change directories to where you have "ACMEInstaller2".

cd /directory/containing/ACMEUninstaller2/
novacom boot mem:// < ACMEInstaller2

K. Android will now install and the device will now reboot again.

L. Boot into ClockworkMod and flash GAPPS.
