For those of you complaining there’s not enough Sprint S4 custom ROMs for your Sprint S4, we have some good news for you. You can easily install any Verizon S4 custom ROMs on your Sprint S4 as well. Yes, we are talking about TouchWiz Android 4.4.2 ROMs.
UPDATE: This method also works fine on Sprint Note 3 (flash Verizon Note 3 ROM on Sprint Note 3). Tested working fine also on Sprint S5 (flash Verizon S5 ROM), Sprint S3 (flash Verizon S3 ROM). DOES NOT WORK ON Sprint Note 2!
Step 1. Install the Verizon S4 custom ROM along with KTweaker kernel. In my example, I used Echo ROM Verizon Port along with Sprint KTweaker kernel, you can get them here:
UPDATE: I found out you actually don’t need to flash a custom kernel, you can just flash the ROM by itself as Verizon ROMs are fully compatible with Sprint.
(I assume you know how to install custom ROMs and you have a rooted Galaxy S4. If not, please root your S4 first then also read up on How to Install Custom ROM on Galaxy S4 first!)

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!
