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.
What is a Custom ROM?
A custom ROM is a custom, modified operating system that you can install on your Android device. Basically it's like installing Windows OS on a Macbook. By installing a custom ROM, you can bypass stock factory settings like locked hotspot tether, install new Android versions early, or even convert your phone into another OS.
With a custom ROM, you can really maximize the capabilities of your smartphone by adding custom features that have been developed by open source developers.
How to Install Custom ROMs
First, you will need to root your device, if it is not rooted yet, follow our root tutorial and root your phone.
Once rooted, you should have TWRP installed on your phone. Installation of a custom ROM is easy if you learn the basic of it. If you don't know how to install custom ROMs using TWRP recovery, see our tutorial on How to Install Custom ROM using TWRP!
So currently I cannot flash any ROM onto my phone since I have updated to mf3??
Witch one do i use for i9505?
The “Device status: Modified” will turn into “Normal” when you running purely stock firmware. Have you try a factory reset?
If that does not work, you need to flash a shipped firmware via Odin.
