Hi kszaq,
first, thank you for your effort in creating the builds for us! I have been using your OpenElec build (some old 6 version) on red stripe MXQ since around March seamlessly. Problem is, that I have decided to do an update yesterday 
I took 7.0.2.5 MXQ version for update, but unfortunatelly, the update stopped, when the progress bar was in the middle, the device rebooted, then the update started again and the whole process keeped repeating.
So I have decided for a clean NAND installation, but all the 7.0.2.5 builds, that I tried (MXQ, HD18Q, m201d) behaved equally as described above.
So I did the NAND installations with all 7.0.2.4 versions. All 3 installed sucessfully, but on MXQ and m201d wifi (and bluetooth) didn't work. On HD18Q wifi and even bluetooth worked, CEC worked, but my remote didn't work. So I took remote.conf from android image and the remote started to work. I tried to turn the device off, but it just went to sleep, unlike the old openelec build I used, which turned the MXQ off. So I did a normal reboot from the menu, unfortunatelly after the reboot wifi and bluetooth stopped working.
I tried also some older openelec releases, but I don't remember the one I used and on none the wifi worked. I even installed android couple of times, where my wifi and android works and did an install of some libreelec versions after that android install, without improvement.
So the best shot was 7.0.2.4 HD18Q version, where after reboot wifi and bluetooth stopped working. Do you have any idea why? Or how to fix it? Anyway it would be also great, if turning off with remote actually turned the device off, so after turning it on, the whole system boots. I like clean start-ups. If you can give me any advice, how to have a functional build, I would be happy to try it. Otherwise I will keep looking for the openelec version I had, but I would like to have new libreelec one with kodi 16. Thanks for your help.
