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!

    and one more thing, i have seen white background and call menu on some galaxy s4 but mine se black is there any way to have that white?

    • Max Lee says:

      See FAQ at bottom of CWM or TWRP post for fix on that, you just need to pull the battery when you see PASS!

      With custom ROMs you may be able to change the background I think.

    I accidentally put click on phone instead of PDA when I rooted my S4 and now I can’t get custom recovery . What do I do

  5. Troy says:

    my s4 said could not do normal boot and stuck in odin mode please help

  6. Troy says:

    i did root my verizon s4 with your tutorial and had clockworkmod recovery but it started only rebooting with factory recovery so i tryed to reinstall and nothing so i did twrp and my phone locked in odin

  7. jason yuill says:

    Does the firmware that is already on my phone (L720VPUAMF9) affect the ability to root my phone?

  8. Bob says:

    Will I be able to root my phone?
    I have a Verizon SCH-I545. I have no access to a computer. I have a SanDisk 64 gb ultra that is factory formatted to exFAT. I have downloaded Easy Unrar Lite.
    I have downloaded the necessary files for root and recovery.
    Many thanks for your time and assistance.

  9. Troy says:

    I have the latest OTA update (UAMF3) for the AT&T version SGH-I337. I have rooted it using the external SD card as outlined by XDA developers. The root is functional now even without the external card installed.

    I am having an issue with installing apps from google play (406) error. Ideally, I would link to install the ROM (MF3 with root) you have on your site but I don’t have CWM installed because of the locked boot loader. Any assistance you could offer would greatly assist. You da bomb!!

    P.S. I had a Galaxy S3 “tricked out” with all your help but I lost it and sadly got this S4 and now have to deal with it.


  10. joncinla says:

    I successfully rooted my S4, and one day, AT&T or whoever pushed out an upgrade to Android, which unrooted my phone back to some default. Now I’m trying to re-root it again, but when I run the run.bat under motochopper, right after “this will take a few minutes’ I get a [-] “Failure message,” it still does the reboot at the end of the run.bat running, but when it wakes up sure enough it’s not rooted. Is there a harder kick that this to complete root?


  11. john cassilis says:

    I have a question, how can I put my apps from my internal storage on to my sd card??

  12. CJ says:

    I could not get root using this method ( LInux) ,in Terminal mode message was as follows:

    Rooting phone……..
    This may take a few minutes………..
    Cleaning up……
    Exploit complete.Press enter

    • Rod says:

      Yes, I’m waiting to install the update until I know there is a Root method for the Sprint Galaxy S4 SPH-L720 running 4.3. Not sure if there is a good reason to update it anyway.

  14. Al Marenger says:

    Anyone been able to find a way to ROOT S4 I9505 after the JB 4.3 update I have tried all the possible ideas from the net and no dice should never have upgraded in the first place but didn’t know about KNOX

  15. Jesse says:

    I’ve recently got a root locked AT&T i337 and can’t unlock root at all
    since they’ve locked boot. Any hope to work around it and unlock?

  16. Tony says:

    Hi Max,
    I have a Dual Sim GT-A9500 in which I have already rooted. You had mentioned that you have Rom for dual Sim as well. Could you direct me to the correct place to download, I cannot seem to find them? I apreciate the help and thanks for all the HTC evo roms I’ve gotten over the years.

  17. Anthony says:

    How do you root the s4 from at&t on 4.4.2

  18. Chaitanya Mohan says:

    Hi, I’m trying to root my phone from my Mac. I saw your video in which you used motochopper. I tried the method.

    This didn’t work on my phone, after everything was done I opened superuser but it says
    “The Superuser binary (su) must be updated. Please choose an installation method.” I’ve tried both but it says that “there was an error installing Superuser. Please send a log of the error to the developer”.

    I even tried installing titanium Back up just to be sure. It says
    “Sorry, I could not acquire root privileges. This application will not work. Please verify that your ROM is rooted and try again. This attempt was made using the ‘su’ command”

    How can I fix this? Thank you!

    Phone Specs
    GT – i9500
    Android Version:- 4.4.2
    Octa Core

    Please tell me if there are any more details you’d like me to provide. New to rooting so not sure what all information is required.

  29. Jay says:

    I flashed the echo s5 ported rom onto my sprint l720t , runs great I love it. Every so often though my signal strength with show as a circle with a line through then come back in a few minutes , I had to manually set the APN settings and I’ve done so with two different configurations But the problem persists. Is there anything I can do for this. Also my 4G never comes in anymore. Great rim though thanks a lot .

  30. JEDICS says:

    Seems myself and many others have been foiled by the kitkat/knox issue, would be great for yo to respond with some guidance to solve this or atleast say there is no solution so we can all stop smashing our heads against the wall.

    If root isnt possible then fine, I just need to know so I can just install factory and sell it so I never have to look at touchpiss again.

    I have the Samsung Galaxy S4 model S975L and running android version 4.3. I have the phone rooted, but I’ve been looking for a way to unlock the bootloader and install clockwork mod but I have been unsuccessful finding anything. Everything I see on youtube is for the I9500 or other phones. My phone is also on the Straight Talk network. I was also wondering how can I find out if there is a OTA update for my phone and update it with root? Please any advice would be very helpful, thank you!
