Hello. I have a Beelink GT1 Ultimate (gxm_q200) currently running Alexelec(coreelec fork) on SD.
I assume you're asking for help in here because the CE devs have no interest in supporting the piracy-ridden fork that rips off their efforts that you installed on your box. I'm equally disiniterested for a) the same reasons, b) because it's not even a fork of the modern-kernel codebase that LE uses today.
NB: As a random coincidence I created a device-tree for GT1-Ultimate earlier today for one of the Manjaro ARM devs to use, so support for the box should filter through to LE11 nightlies sometime soon.
