Aquaris E4.5 Ubuntu Edition Custom Rom and OS

Hello,

I recently acquired Aquaris E4.5 Ubuntu Edition from a friend. However I couldn't get WhatsApp working and couldn't find Sports Tracker app for it, so I decided to install Cyanogenmod for it. I had it on my previous phone and I was very satisfied with it. I found info that it would work on the device http://www.htcmania.com/showthread.php?t=1060364 (had to use Google Translate though since I don't speak Spanish). So first I installed Android on my phone following this guide http://www.mibqyyo.com/en-articles/2...iscussion_id=0. In that I had no problems and I have now Android on my device.

As I understood I have to install Custom Recovery ROM, and on the forum TWRP was mentioned. I found that it does support the device, https://twrp.me/devices/bqaquarise45.html. I tried installing it through fastboot, installed ok but it got stuck on boot loop. Tried other versions also, same problem. I reverted back to Android and tried to install it through apk file. Didn't work either, had some problem like 'SELinux is not permissive'. So I have now stock Android, but I'd really like to install Cyanogenmod or at least Xposed installer, both of which I caot do since I caot install Custom Recovery ROM. Has anyone here managed to do so or know anything about it? Much thanks in advance!
