Complete install of Android on the device
I was in the same position I'd tried everything. In the end I decided to start from the beginning. What I did was pretty hardcore. I completely uninstalled Android. You need to erase the usb drive in Webos. you do this by booting into WebOS, going to settings/device info/reset options/erase USB drive. Remember before you do any of this get all you data of your device to you PC. Once this is done you are ready to install Android again. Now I found it was easier to upgrade from CM10.2 Data/Media build to CM11. So I installed Android on the device using these four files;
These files are available as a package at rootzwiki.com. There you will also find instructions on how to install android again and how to unistall android as well. Once android is installed now you need to resize the media and data partitions with tailor in webos. Now that this done you are ready to upgrade to CM11. So then booted up my device into Android. Then I connected it to my PC. enable USB conductivity on the device. I created a folder on the device on the now larger data partition (I used the same cminstall name for the folder).Transfered the CM11 (milaq version), Gapps and CMW 6.04.7 to this folder.
I would then boot into recovery. Now were going to update the CMW. choose install from zip find the folder and the CMW 188.8.131.52 file. install it.
once installed boot back into recovery. Now were going to inst CM11. First you need Perform a factory/data reset and wipe/format cache partition. Once this is done your ready to install CM11 and the Gapps. Choose install from zip. Find the cminstall folder you made install. then do exactly the process with the Gapps.
Android CM11 Milaq should work. This worked for me.
Hope this helps.
