I just switched from an S3 to an S4 and didn't realize that the S4 is seemingly so much more locked down. (bummer). I've rooted (with Vroot) and want to move to CM11. But before I do so I want to backup that stock, rooted, MJ7 rom. Booting into (stock) recovery doesn't show a backup option. Am I missing something? Am I being unjustly cautious not going to a custom rom without a backup. (I do have Odin and the .tar file -- which I had to use when I believed TWRP when it suggested that I could install a custom recovery -- thereby softbricking the thing. But it was easy enough to recovery. Annoying but harmless). A second question. I really like the Samsung 4.3 keyboard with the numbers on the top row. If I go to CM11 or whatever can I still install/run that keyboard?
