Guide To Install Gingerbread (Android 2.3.5) On HP TouchPad

Last week, Touch Droid’s team posted a “semi-working” build of Gingerbread (Android 2.3.5) for the HP TouchPad. The 11 step process requires interacting with the HP Touchpad using a terminal window to execute linux commands and install Android. The technique also includes a way to recover to WebOS, however the two are not dual bootable just yet.

“I have decided to release a system dump from my TouchPad which contains a semi-working build of Android 2.3.5 with working touchscreen on the HP TouchPad. Please use this data and the below steps on installation as you see fit. I hope this release will light a fire under the community to work together on a full working port!,” said a user on Touch Droid.

If you’re feeling particularly adventurous, you can watch the video embedded below, or follow the steps outlined under this post:

Steps on installing this onto your TouchPad

0. Plug your HP Touchpad into your PC via USB and DONT MOUNT IT.

  1. First you will need novaterm/novacom. Follow steps at the following URL to get both installed on your machine: http://www.webos-internals.org/wiki/Portal:Accessing_Linux
  2. Open a command prompt / terminal window and type the following:
  3. We will need to create partitions for android on the device. Run all commands in novaterm: Resize /media first:
    lvm.static lvresize -L -1706M /dev/store/media
    lvm.static lvcreate -L 10M -n android-persist store
    lvm.static lvcreate -L 32M -n android-etc store
    lvm.static lvcreate -L 320M -n android-system store
    lvm.static lvcreate -L 320M -n android-cache store
    lvm.static lvcreate -L 1024M -n android-data store

    Create partitions for android:

    mkfs.ext3 /dev/store/android-cache
    mkfs.ext3 /dev/store/android-data
    mkfs.ext3 /dev/store/android-etc
    mkfs.ext3 /dev/store/android-persist
    mkfs.ext3 /dev/store/android-system
  4. 4. Mount the system partition on /tmp/system (in novaterm).
    mkdir /tmp/system/
    mount -o loop -t ext3 /dev/mapper/store-android--system /tmp/system/
  5. Open a new command/terminal window and run the following: **Do this in cmd/terminal not novaterm**
    novacom put file://tmp/system/system.tar.bz < system.tar.bz
  6. Unzip system.tar.bz and move files to /tmp/system/ (in novaterm):
    cd /tmp/system/
    tar -xvf system.tar.bz
    cd system
    mv * ../
    cd ..
    rm -rf system
  7. Run the following to unmount /tmp/system:
    cd /
    umount /tmp/system
  8. Now boot into bootie by running the following in novaterm:
    tellbootie recover
  9. Open a new command/terminal window and change to your novaterm folder and run the following:
    novacom boot mem:// < android.uimage
  10. Start pressing Volume UP on the TouchPad until you see a purple line on the right hand side.
  11. If all steps were followed correctly you should boot right into Android 2.3.5 and have a working touchscreen.

    ** To boot back into android after restarting you have to repeat steps 8 and 9 only.**

    If you would like to remove this and revert back to normal WebOS run the following in novaterm:

    lvm.static lvremove store/android-persist
    lvm.static lvremove store/android-system
    lvm.static lvremove store/android-data
    lvm.static lvremove store/android-cache
    lvm.static lvremove store/android-etc
    lvm.static lvresize -L +1706M /dev/store/media
