For those of you with AT&T Galaxy S4 SGH-i337 or Sprint Galaxy S4 SPH-L720, we have some good news for you there are stock firmwares now available so you can fully unvoid and unroot your device. There should be more coming for all the other variants such as T-Mobile and Verizon so stay tuned folks. Also, stock firmwares are already available for GT-i9500 and GT-i9505 users at SamFirmware.com.
CWM Recovery “stable” version is NOW AVAILABLE for Sprint SPH-L720 and T-Mobile SGH-M919 Galaxy S4 users. I just verified with my Sprint and T-Mobile Galaxy S4, works 100% fine!
What does this mean?
For those of you who want to install custom ROMs and make backup ROM, you can now use CWM recovery. And also you can now root your Sprint or T-Mobile Galaxy S4 using the CWM root method.
[nextpage title=”Steps 1 through 5″] For those of you who want to unroot your Galaxy S4 and remove root completely so your phone is back to completely stock, it’s pretty easy to do with ODIN and stock firmware.
This is great to get your phone back to stock status for returning your Galaxy S4 for warranty or perhaps you’ve ended up in a bootloop and simply want to get back to stock ROM.
After rooting your Galaxy S4 with CWM method, I highly suggest you to make a backup ROM before you start installing a custom ROM or anything else.
What is a backup ROM?
Backing up your ROM will back up your whole system including your apps, app settings, and everything except your personal media such as photos and videos. Having a backup ROM makes it easy to recover your phone when something goes wrong such as bootloops.
For those of you who need to repair your Galaxy S4 for either LCD screen replacement or parts replacement (such as fixing broken micro USB port, camera, etc…etc…), here’s a video tutorial that shows you how to easily disassemble and re-assemble your Galaxy S4.
Update: I’ve also replaced my broken screen glass on my Galaxy S4, see How to Replace Screen Glass Only on Galaxy S4!
Probably one of the most common questions I get is, “does rooting Galaxy S4 void my warranty?”.
And the short answer is yes and no. Rooting by itself does not void warranty. But if you root your Galaxy S4 by installing a custom recovery like TWRP or CWM Recovery, you will increase your binary counter (What is Binary Counter?), which in essence voids your warranty.
Rooting Galaxy S4 means that you gain admin access to your phone, sorta like having admin access/username for your Windows/Mac/Linux computer. In layman’s terms, you are basically getting 100% control over the Galaxy S4 you already paid for.What does rooting Galaxy S4 do for you?
