Could not awake my box from power-off and "fixed" it now. The android-firmware i was upgrading from, had the same shutdown-start issue (despite remote working once the box was started), it was not the original stock firmware for my box! I guess the remote control driver is fixed in the bootloader (?) and LE is keeping the bootloader. So when upgrading to LE, use original stock firmware. Nexbox MXQ Pro s905 1GB/8GB worksfine now, with p200/1gb/Realteak-dtb.
Thx for this build kszaq!

Bricking is very unlikely. Flashed my box more than 100x, when trying to make custom firmware. Messed things up by switching uboot, kernel, recovery etc. was no problem at all, USB Burning Tool revived my box'es everytime again.
If you want to write to NAND read post #1 again. You will have to run "installtointernal" via ssh, there is no LibreElec Image to use "burning tool". If things go wrong just use burning tool.
