I own both the Beelink GT1 1GB DDR 16 GB drive and the Beelink GT1 Ultimate with 3GB DDR and 36GB drive.
I have been able to install LibreELEC on the first Beelink GT1 but not on the ULTIMATE version of the box.
I used LibreELEC-912.arm-8.2-22.214.171.124.img.gz and have tried the device tree files gxm_q200_3g.dtb ,gxm_q201_3g.dtb, q200_2g.dtb and q200_2g.dtb without any success.
I started the box using the normal toothpick method and all I get is the Beelink Android symbol on the start up screen and nothing happens after that.
I also tried booting into Android 7.1 and installing a Terminal Emulator and used the command 'reboot update' with the micro SD card installed with no success.
I used the program LibreELEC.USB-SD.Creator.Win32 to flash the class 10 micro SD card.
Having had no problems with the earlier Beelink GT1 box I cannot understand why I am having no success with the later box.
Any help will be much appreciated. Thanks
