Go back to stock then step back from the bleeding edge. No decisions stop you doing that but your own
I think Shoog is referring to the fact that developers are now only working on the latest version of LE rather than adding support for his hardware to older versions.
Self entitled springs to mind, purchasing a particular device does not guarantee you anything. You can purchase a high end smartphone costing 10x what you spent on your device and get little to no support, so expecting it from us or even the Khadas team for that matter is overreaching in expectations.
To give Khadas some credit though they do try more than most manufacturers with their users and they even sent afl1 some free hardware to get the DTV daughter board working within LE.
All support given within the LE community is a courtesy and not a right, just because I and the LE team provide images that does not come with an implied guarantee of support, everything you do with your hardware is done at your own risk and we can not be held responsible or be expected to address any possible issues that may arise.
