I know many of you have been asking me you want to update your phone to the latest stock firmware. Well, you can do that but on certain models like AT&T Galaxy S4, once you update your firmware to latest MF3, you can re-root it but you will lose the ability to flash CWM/TWRP recovery.
Also, using ODIN and stock firmware usually requires using a Windows computer and can be a long process sitting by your computer.
If you are not returning your phone back to the store for warranty purposes and you simply want to re-install stock ROM, you can simply re-install CWM/TWRP flashable rooted stock ROMs. These are 100% stock firmwares but with rooted added and it will not re-install stock recovery, meaning you will be able to keep your CWM/TWRP recovery if you want to install another ROM.
Currently, I did make a new page so it’s easy to find these rooted stock ROMs for AT&T, T-Mobile, Sprint, and Verizon, check them out here.
