I was just doing some research on Amlogic chips and came around information that S905D3 used in VIM3L is basically the same as S905X3 with one significant difference that S905D3 supports HD DTT tuners. Since I do not need TV tuner support I have a question if VIM3L is compatible with S905X3 firmware?
You are correct. I need an android rom which would support USB touchscreens. Neither of the existing firmwares works with my display. I noticed that this problem was reported frequently by different users with different display models, but there is no solution for the moment. Unfortunately I do not know how to compile an Android rom, so I guess I will have to wait and hope that the official rom will include the fixes in the updates.
