Just realized that when I flashed my last Rubix update I'm now running 2.2.1. I like Rubix, but like some on here I'm a ROM switching fiend. I'm aware of the risk of running 2.2.1 and the lack of a full SBF, at least at this point, works been busy. Mistakes were made before I realized the lack of full 2.2.1 SBF. My question to the AF community is, should I run into any problems if I try to flash the anything new such as the JRummy ROM, the new Apex, or even the new Tranq? At this point I'm cautious to even restore my TranQ 3.0 back up. What should I expect if I give any of this a try? Thanks.
