Finally, a standard rom for the V3 stick! It's a work in progress but I don't want to leave anyone waiting for their V3 to work properly.
So here is what I have so far. Complete custom rom from the ground up, system.img pulled from mk908-jjhmod-v1.5 as it works well in this situation. Rooted, init.d, 720 and 1080 options. The two problems I have with the kernels I have included with this rom are: Can't get the cpu to go over 1200mhz and can't get the ram to scale above 400mhz. I'd take either one, and eventually will get both figured out I'm sure. Currently the kernels don't run as fast as I'd like, but they run and they are stable. I tried a random xbmc build on it and had great luck.
So without any further blabbing:
p.s. Honestly this stick is a pain in the a$$. I've recently gotten a cx919 and mk802iv and was instantly able to build kernels that ran great and fast and mod the firmware very easily. They weren't much different in price either so if anyone hasn't dived in yet and was considering the mk908, I'd go with another option currently.
