PlasmaActive (MER) on A2109A

[AndreasWatch]

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...



HOWTO Install


Format your SDCard and mount it
change "MICROSDPATH" to match your device

MICROSDPATH=/media/sdcard

Download the Nexus7 MER/PlasmaActive4 image

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

sudo tar xf plasma-active-4-armv7hl-google-nexus7.tar.gz -C $MICROSDPATH

Add needed files for A2109A and remove the unneeded Nexus7 files

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

sudo sync

Get the kernel

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:

# 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

# cd to the right directory:
fastboot boot boot.img

If you want to restore your Android Bootimage, just restore it from your backup:

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):

/sbin/modprobe bcmdhd
nmcli d wifi connect "SSID" password "PASSWORD"
