Now my questions are....
Am I able to upgrade the firmware to like 7.1, 9.0 etc? I want themes and other features.
Am I able to backup my whole CFW installation so I can easily restore when I want to get back to CFW if I ever remove CFW?
Is it possible to run the applications that are for CFW, without going to system settings, profile etc?
If this is illegal etc, then I'm sorry.
Ok, so to start, cfw essentially is just a buggy and unsupported version of gateway. To be able to play games that require 7.1 or higher, you must be either using gateway, sky, or legit games.
Cfw is stuck on 4.5. You simply cannot go higher and still use cfw. The only way would be to either pay the price of gateway, or stay on 4.5, or write your own cfw, which is often too much trouble, even if you have the skills to do it.
No, you cannot Skip doing the DS Profile Exploit. You must do it successfully in order to play your cfw installed games. There are a few games that do work on sysNAND, but it's like, only 4 or 5 of them, and they may or may not work with a console on 4.5.
I don't know enough about cfw to know if it is possible to back it up. I'm sure if you created an image of the SD card(all partitions and such, also were not talking about cameras
) you would be able to restore whenever.
But ye,either pay the price of gw, or use the cfw. IMHO, cfw is not worth the trouble, and gw is totally worth the price tag.
