now i answer myself, i hope everyone can help with this following issues (after sleeping now 5 hours experinces,,,):
--------i have a complete great working box "KII Pro", i need to clone this box 1:1------
on the box works 8.0.2c-I
i download LibreELEC-S905.arm-8.0-8.0.2c-I.img.gz
put it on my SD card (rufus) , download gxbb_p200_k2_pro.dtb and replace it to dtb.img
libreelec starts, checking/resize storage and reboot, kodi picture starts, the screen goes black and the box shut down (green LED goes Red)
i can start the box new, libreelec/kodi comes, (only the kodi 17.3 Picture) but the box goes shutdown!
When i start this SD card on my working kodi box, a new Kodi starts! with default settings!
Ok, the box is damaged? I have more then one, new Box packed out and start again! The same one, libreelec starts, kodi pictures start, black screen, box goes shutdown itself.
Ok, i see from @sinancetinkaya the Image
LibreELEC-S905.arm-8.2-devel-201710231024-gd562e8e-I.img.gz
i burn it on SD, put right dtb on the SD....starts again on a new Box, that Kodi works! but i cannot use my old settings from 8.0.2c-I, something dont works, and i see i dont have a Lan Port, only WLAN works. I must have LAN. Anyone have a Idea why only WLAN works on this Version?
i have tested a Version wirth 8.9-k, works too, but Kodi 18, and then i must do complete new all addons.
Can anyone help me with my issues?
