Working ROM Port! (Mostly)
So i was looking at this tablet again and found a Android 6.0.1 ROM for MT6582 that had KitKat ROMs, I downloaded it and made a port to test and it worked other than the screen rotation being off with the touch panel. Also it has no Google Play Store unless you flash gapps and only basic apps to use it, so I flashed gapps pico and the XOSP Apps zip I got from the ROM page as well.
So it boots slowly to start and has no on-screen NAV buttons, but you can turn them on in setting under XOSP part. The ROM is also for a phone and not a tablet so everything is a bit big on the screen and sometimes on reboot it shows the boot animation and then goes black, don't know why but if you wait sometime it starts working and other times you have to power it off and on again to fix it.
One odd thing I found with it was in setting under storage it shows a small SD Card as corrupted, it about 100-500BM in size and can not be formatted. (Some info apps show it as bigger than others)
I have added a download for a buildprop.prop updater as you may need to change the last value to fix thr screen rotation.
Please do not PM/DM me about this port as I don't check messages often and a reply to this post will be seen a lot quicker and by others that may be able to help you as well.
I hope this helps some of you out there.
