Hey there forum!
I've got this MXQ PRO 5G TV Box (Yes, I know It's been said the brand isn't important, but I figured I might as well say it anyways) thing a few days ago and, as you do, my first instinct was 'Let's linux it', which Is, as It turns out far more trouble than I had initially imagined. And frankly I am a little tired of slamming my head into a brick wall, repeating the same steps again and again so as a sort of last resort, I'm here to ask for your help (thanks in advance).
To check which image to download and what steps to follow I've opened the box to take a peek at It's board. As the main CPU, RK3228A, for the storage 128GB of eMMC, and for the memory 8GB of RAM (which exactly type, I can't discover).
Following the instructions on the first page of this topic, I downloaded an image, downloaded multitool, got my SD card. At first everything went according to the guide. Multitool flashed, the thing booted It and the partition expanded, then I shut it down and put the extracted .img into the 'images' folder, plug the card back in boot, flash, shut down once more and upon trying to boot, the LED stays off and doesn't turn on. After waiting for a solid 10 minutes I decide I'll just try booting it directly off the card. I flash It, plug it in and some images booted partially and some didn't. Some boot only to a certain point like starting a specific service (usually it got stuck after or during starting armbian-ramlog.service) and some just don't boot at all. I've tried disabling the services by manipulating the files on the card yet they just reappear again.
After that I noticed that upon each boot there's a quick 'error' that happens, returning different numbers seemingly depending on the image on the card, either Internal error: Oops: 805 [#1] SMP ARM, or Oops: 80000005 SMP ARM or just Oops 5 which as far as I could find meant something related to illegal instructions (specifically interrupts). I haven't really made any progress past that. Also, If It's of any help, I can provide images of the board (from both sides) and all of It's components.
Thanks in advance for all your help, friends!
