I just got a Tolino Vision 6 and was disappointed to see there doesn't seem to be much work on it (apart from some posts on allesbook.de on how to root it)...
Here's my twrp port based on that of nook glowlight 4 (both devices use the same Allwinner B300 chipset).

I played around with it a bit and it seems alright. Even the brightness control works
