Libreelec doesn't boot first time

I installed Libreelec into sd card, but unable to boot the system for the first time. Mbox H96-II TV box model (it is some clone) .It have no 'reset' button.

I tried some methods outlined at the HOWTO guide, but my Mbox H96-II have no reset button, but available methods not works for me.

I installed Terminal Emulator app, tried run 'reboot update' command, the TV screen turn off, tv box just stay and LED flashes endlessly, no progress.

Recovery metods methods not work too, there is no"Reboot to recovery" option (1nd variant) and 2nd recovery method not applicable as well.

Is there way to make it work?

Have you got the correct device tree? Try another, I do not know which one you need.

I used gxl_p212_2g.dtb, which I think is correct device tree for S905X box with 2GB RAM amount.

I replaced the one that's already was in main folder of SD card. The new device tree ~40KB is much smaller than was the existing one.

However, it is not clear should i replace the existing one or not. Because, in the guide noted "S905X: You can leave a tree that is already present on SD card (fresh install only) or choose one according to your RAM amount."

What do you mean? Tv box RAM about 2GB, 100Mbit Ethernet

in menu settings seems was shown amount memory available is 1.7GB

I recreated bootable sd card again, and LE loads now. But remote not working, can't proceed and configure.

I have LibreELEC 8.2 [8.2.3.1]
