Build vim2 firmware including root support

Glad to hear it is making progress.
I cannot recall if this ROM is rooted or not, though he often has unrooted ROMs(unless “Debug” is in the ROM file’s title).
Read the page carefully, as version one must be on eMMC first, then version three gets applied by OTA method(SD card).
Hope you get your VIM2 working and back and in a short time.
