First thanks a lot for this great work here. Libreelec runs really good on this "cheap boxes" and the community here and on kodi is more than great.
But now i did i mistake on update progress.
I had Version 7.0.2.007 running on NAND and wanted to upgrade to the new Version 8. So i put the img.gz file and the devicetree gxbb_p200_2G_1Gbit_RealtekWiFi.dtb
renamed to dtb.img in the update folder. Now my box won't boot and after the 120 Seconds autorepair, there is a message that tells me to install LE again. I tried allready to install the original FW via SD Card, the SD Card Version of LE, The Original FW with the LE update, but nothing worked. Did i brick the box? It seems that the NAND is corrupt now (because of the wrong devicetree? ) I'll buy the special USB A to USB A cable to try it with the Amlogic tool this weekend, but if there's another solution would be great to hear about.
Sorry for my english
