[hr]You can first try running one of the newer builds from a separate SD card. There you can change dtb.img as many times as you want without making any change to your device or risking a brick. I would recommend trying gxbb_p200_2G_1Gbit.dtb.
Hi kszaq,
Thanks for the advice, I will do the procedure starting first with your recommended built & I will share my results.
What I noticed is, that this version of LIBREElec is not localized - I prefer to have it in my mother language (like 7.0.2.005), but this is not really bothering me. One thing though, which I have overlooked in the description - it is based on Kodi Jarvis 16.1 version, so same which I have now. I wanted to have the kodi Krypton 17.0, therefore I am going to test now on my KIII the LIBRelec 8.0.0b based on this version. I will also burn it on clean SD card just in case. If everything works fine I will carry out the Update procedure following the kszaq's instruction in the other topic.
