    A few days ago I saw that there was released a KDE Plasma Active 4 image for the Nexus7.
    Because don't have a N7, I tried to port the image to our tablet...

    The result is a bootable Plasma Active, as you can see here:


    What works (almost nothing)
    -Xorg
    -Touchscreen
    -Wifi

    What not works (all the rest)
    -Accelerated Graphics
    -Sound
    -Bluetooth
    -Powermanagement
    -....

    Disclaimer
    Please don't try to install if you don't know what you do and make a backup of your Android installation and your sdcard!!!!
    I just share this to see if there is anyone else interested in and could help to make it running better.
    Please don't expect a good and stable system, the most things I've done (an that's not much) are based on try and error...:confused:



    HOWTO Install


    Format your SDCard and mount it
    change "MICROSDPATH" to match your device
    Code:
    MICROSDPATH=/media/sdcard
    Download the Nexus7 MER/PlasmaActive4 image
    Code:
    wget http://files.kde.org/plasma/active/4.0/images/nexus7/plasma-active-4-armv7hl-google-nexus7.tar.gz
    Extract the image as SU to your MicroSD
    Code:
    sudo tar xf plasma-active-4-armv7hl-google-nexus7.tar.gz -C $MICROSDPATH
    Add needed files for A2109A and remove the unneeded Nexus7 files
    Code:
    sudo rm $MICROSDPATH/etc/X11/xorg.conf.d/01-nexus7*
    sudo rm $MICROSDPATH/etc/X11/xorg.conf.d/10-rotate*  
    curl http://pastebin.com/raw.php?i=3x1L05Pf >  $MICROSDPATH/etc/X11/xorg.conf.d/01-lenovo-a2109-input.conf
    wget https://www.dropbox.com/s/zfj80t5cv659etj/modules.tar.gz
    sudo tar xf modules.tar.gz -C $MICROSDPATH/lib/modules/
    Sync your SDCard
    Code:
    sudo sync

    Get the kernel
    Code:
    wget https://www.dropbox.com/s/dtj3lgo5gngorv9/bootimages.tar.gz
    The kernel has to know where MER is stored, depending on your SDCard/Configuration you need an other bootimage
    If you have only one partition you need the bootimage "noInit-bootimg-mmc"
    If you have more partitions, it depends on which partition you have stored your MER-image.
    Partition 1: noInit-bootimg-mmcP1
    Partition 2: noInit-bootimg-mmcP2
    Partition 3: noInit-bootimg-mmcP3

    You have two options to boot the image:
    1. CWM-Recovery:
    Code:
    # just place the right bootimage and nandroid.md5 in your clockworkmod/backups directory 
    and restore through "backup and restore" > "advanced restore" > "noInit-bootimg-mmc**" > Restore boot
    2. Fastboot
    Code:
    # cd to the right directory:
    fastboot boot boot.img
    
    If you want to restore your Android Bootimage, just restore it from your backup:
    Code:
    CWM > "backup and restore" > "advanced restore" > "yourBackup" > Restore boot
    If you know how to do something better, please give me advice or add a post


    The kernel configuration file I've used: http://pastebin.com/eFhqfD3P

    Activate Wifi (won't work though the GUI):
    Code:
    /sbin/modprobe bcmdhd
    nmcli d wifi connect "SSID" password "PASSWORD"
