Thanks again Kshi!
I bought these boxes a couple of years ago, but found them pretty limited at the time.
Thanks to the efforts by devs like Demetris my box actually 'got better with age'.
I started with the MXIII builds and 'upgraded' using the latest 8.2.2 S82 .tar file, but I will go back at some point to see if I could have just used the S82 SD image. I did issue the 'touch /storage/.update/.nocompat' from SSH prior to performing the update - maybe not needed if you start from S82?
Also, I haven't been able to boot my box via USB yet, so it took me a while to figure out for my hardware, a SD card was needed.
BTW - Is S82 short for S802/S8x2?
These boxes must use the S82 image Beelink S82, Orbsmart S82, Tronsmart S89(-H), MXIII(2G)
