I did get this to work by SDcard and am running 8.2rc1 on my MXIII-G 2g/8g.
I decided to reload LE 7.0.1c from Wilro's post on Freaktab - it worked well for me in the past):
[ROM] Unofficial OpenELEC for MXIII-G & Tronsmart MXIII+ - FreakTab.com
I used the old method as described in the post second section- toothpick install to enable sdboot.
1- Download "Enable SD card dual boot" zip file, extract & copy files to sdcard/thumb drive (I used sdcard) - OpenELEC-MX3G.arm-DualBootSD.zip
2. "Toothpick" boot your device into (original) recovery mode (took~30 seconds), select install ZIP from EXT & select "OpenELEC-MX3G.arm-DualBootSD.zip" Note that there was an error on the bottom line of the zip screen - E:/misc - I didn't write it down. It had no effect on the process.
After the zip ran I formatted the sdcard with SDformatter v 5.0. Then burned the ROM image to the sdcard:
1. Download Libreelec - see post on page 476 page 32 - I used the 7.0.1c link and downloaded this image -
LibreELEC-MX3G.arm-7.0.1c.img.xz
2. Unpack the image to your hard drive and then burn it to SD card - I used Win32diskimager
3. Insert SDCard in box & boot your device - I pulled the plug before I inserted the sdcard (no toothpick needed) - This will take a while as it prepares the sdcard & installs the system for the first time - It will reboot when finished.
4. As soon as Kodi loaded up I ssh'd into the box and put the Demitris update file along with the remote.conf and .nocompat.zip file into the update file and rebooted via putty.
LE 17.4 loaded and has been running for some time with no obvious problems. I have rebooted a bunch of times and have had no problems.
Hope this helps. You have certainly provided a lot of help to other users including me on other LE forms.
Thanks kostaman and thanks to wi
