Alright, so my dad has the Sprint Note 2 with Ma7 stock TouchWiz rom rooted. I don't want to put him through a whole firmware upgrade so I was just going to install an AOSP rom, it has to be 4.4 because he nor I like 5.0. I would like to know which one is stable and won't require any updates. The reason he wouldn't switch to AOSP before was because they had bugs. Thanks
