How to Install Custom ROM using SafeStrap on AT&T/Verizon Galaxy S5!

For those of you who have rooted your AT&T or Verizon Galaxy S5, you are probably wondering how in the world you are going to install custom ROMs when the bootloader is still locked.

Thanks to excellent XDA developer Hashcode, we have a solution!  You can still install custom ROMs using SafeStrap Recovery (a modded TWRP recovery that works with locked bootloader).

Before we begin, you will need a rooted AT&T or Verizon Galaxy S5.

Step 1. To install SafeStrap recovery, you will need Busybox.  You can download the BusyBox app to install BusyBox on your rooted Galaxy S5.

Make sure you download the correct version for your Bulid number.  You can check your Build number under Settings->About device.

Since my Build number ends in “ND3”, I am going to download the ND3 compatible version.

Also download the latest version, version numbers are incremented along the lines of “B01”, “B03”.  Just get the one with higher number, use your common sense.

    this looks like it confirms what I have read elsewhere, that the slots in safe-mode are not working. Am I correct?
    I have been waiting for you to do this to make it sure it is as safe as it gets.

    • Max Lee says:

      I believe they are working I just don’t recommend it as your storage size on ROM Slots are limited to 2.5GB instead of 32GB.

    • Doug says:

      My att S5 is “ng3”. The only option is the “nd3”. So I can’t go any further than this step. I bought an S5 from eBay and have it in Canada on Rogers. Unlocked it and found a method to root it successfully. Nothing is easy on this version is it?
      CWM is not supported any more and twrp doesn`t work because of the locked bootloader. Is that right? You have to use safestrap?

    Where do we find the VisionX Rom?

  3. Chris says:

    Thank you Max! Very helpful for this AT&T GS5 owner.

    i have been rooting and jailbreaking since my galaxy s2 and ipod touch 2g. i have always thought you could only flash at&t roms on at&t devices and verizon roms on verizon devices. how come at&t galaxy s5’s are compatible with tmobile and international roms. is it just hardware or software?

    • Max Lee says:

      This is because AT&T S5 has nearly identical hardware specs as T-Mobile and international Qualcomm models. Samsung is NOT going to make a new phone for every carrier, it’s going to cost them millions more. Instead, they just rebrand the phones and put different software, which is why we can flash other models on AT&T S5 and vice versa. This isn’t always the case though, we got lucky with S5.

  5. Chris says:

    The process worked like a champ… follow of yours since galaxys3root.com and very appreciative of your websites and your web presence Max. Thanks for all you do for us.

  6. John says:

    Does this void warranty??

    • Max Lee says:

      No using SafeStrap doesn’t.

      • Steve says:

        Hi Max,

        I rooted my Galaxy Note 10.1 and installed the Tundra ROM, using your help, that was great!. I am, however, a bit confused about what you said regarding the fact that using Safestrap does not void the warranty? I thought that once you go through the whole process of installing that, along with SuperSu, etc. then the device is indeed rooted. Wouldn’t that mean that the Knox tracking code is updated? Also, what else is needed here to get full use of the SD card? Thanks!

  7. Jeff says:

    Any ROMs you recommend for Verizon S5 yet? Thoughts on the Sly Hyde ROM?

  8. Andrew says:

    I can’t find any roms compatible with verizon… I cant use any other model rom other then SM-G900V?

  9. Oliver says:

    Max, after installing a new custom rom do you have to re-install safestrap to be able to get into recovery?

  10. Michael smith says:

    How come when I flashed this alliance rom it no longer says lte it just says 4g?

  11. Michael smith says:

    Do you know why I can’t receive pics but I can send them. I only noticed it on the vision x Rom but if I flash back to stock AT&T I can receive them

  12. melsor milan says:

    Manage to install safetrap and ellikikat ROM for Verizon. Everything works except that the miscellaneous fle is still 5.65 GB even if I it is debloted. The ROM is 4.17 mb only. Why is the miscellaneous file forlder is so big?

  13. DaMiz says:

    Hi I got a G900V S5 Verizon but I switched to T-mobile, it works and all but there is a few annoying limitations, No Wifi calling, No tether option (it’s saying i should be on Verizon sim to use this feature not in those exact works of course) I can make foxfi work but I dont like it, it keeps on adding 1 to all my contacts which is weird ( example: it will add 1 to 1626-123-567, it will look like 11626-123-4567) of course it will not connect so I have to remove the 1 on all my contacts. It also does it to my VM short but like when I press 123 or press and hold 1 it wont go cuz it will dial 11626-123-4567. I was hoping there would be a Custom rom that I can fully switch functionality to Tmobile, or atleast open it up so that Verizon stuff wont keep on opening. I saw Alliance has been the rave of Verizon S5 but I dont see it stating that they have taken all the Verizon stuff out. Im already rooted and ready to go but I dont know what Rom would be best for my requirements and of course be able to custom other stuff. Any help would be appreciated. Thank you in advance.

    • DaMiz says:

      sorry didnt proof read. I hope it still make sense? lol

      • Max Lee says:

        You can try install a T-mobile custom ROM, it should work.

        • Damiz says:

          Which one do you recommend? X-note or alliance for tmobile? Do you know which one works for sure, or has been tested before? Thank you again.

        • DaMiz says:

          Thanks for the suggestion. Im downloading as we speak. But I so a post that you posted a while back July 13th when someone asked if it would work with Verizon and you said “NO DONT INSTALL” not sure if that was for the old version and now you think or have seen the new version work with Verizon? Please let me know I know the risk of installing custom rom is there but cant afford another phone dont want to kill it if its known to not work. =)

          • DaMiz says:

            Did it, worked like a champ!!! Thank you. Your site is always helpful and accurate. G900V Confirmed working with Alliance Tmobile. Finally every T-mobile feature is working including Hotspot!!!

            • Max Lee says:

              Nice, thanks for the feedback. Most T-mobile ROMs should work on Verizon as they share same CPU but not the other way around I think…

  14. Matt says:

    If I have a Verizon S5 and unlock it to use on any network, does that mean I can use the international “F” ROMS or still only the verizon based ones?

    • Max Lee says:

      Still only Verizon ones really but there should be a patch later down the road, which you can use to flash international ROMs.

  15. Ryan says:

    So if you do as described is Gapps no longer needed or is it incorporated into ROM?

  16. Chris says:

    Max, why is this website not updated more often? I suppose there aren’t many custom ROMs for the GS5. I’ve followed your websites since Galaxy S3 Root .com and like a lot of folks, I love your work and appreciate every update. Keep up the good work.

  17. kevin lee says:

    hello Max Lee, I would like to ask your helping if you can find the resolute. i accident cleaning the system, now I turned on the Samsung galaxy icon” unlock custom” stuck logo, can you help me to solute the problem? i have on rooting which is i have G900A ATT Safe strap.. I tried to use Odin 3.9 to do flash for stock firmware. but it is failed. please let me know thanks in advance.

    • erick says:

      Mira podes recuperarlo con este firmaware que desbloquea el gestor de arranque, porque me lo imagino que se quedó con el logo friziado de samsung es decir no arranca, entonces utiliza este archivo que te sacará de este problema, mira solo te pido que respondas y comentes al respecto si te soluciono o si no para poderte orientar a una solución urgente
      el link es el siguiente hola…tengo el mismo comprado en B&H en New York…
      El modelo es SM-G900A es de AT&T
      Cargale con Odin este firmware: G900A_Downgrade_to_NCE.tar
      luego bajate este OTA: G900A_NCE_to_NG3_OTA.zip
      y después este: G900A_NG3_to_OA1_OTA.zip
      Luego pones el archivo G900A_NCE_to_NG3_OTA.zip y el G900A_NG3_to_OA1_OTA.zip en la tarjeta SD del teléfono e inicia en modo recovery y luego instalas desde la opción upgrade desde SD el archivo G900A_NCE_to_NG3_OTA.zip , cuando termine de instalar y reinicie entras de nuevo en modo recovery e instalas de la misma manera el archivo G900A_NG3_to_OA1_OTA.zip
      Y Listo el Celu queda en Android 4.4.4 Original sin perdida de Garantía y podes usar todo inclusive la Zona WI-FI compartida.
      PD: No le cargues un firmware que no sea de AT&T si no queres quedarte con un pisapapeles.
      Saludos
      Podes a traves del odin cargarle el primer archivo y recuperas el movil, yo no lo he probado subirle al 4.4.4 porque la verdad se me puede malograr el gestor de arranque pero si voz lo haces es bajo tu propia responsabilidad

  18. jonny mo says:

    I’ve noticed that when using safestrap to install a custom ROM that has a AROMA installer that safestrap freezes. It does this with any ROM that uses the AROMA installer. Any thoughts or solutions for this?

  19. justme says:

    I was able to successfully install Alliance on Rom Slot 1. It did give me a message about something being damaged, but after removing the battery and activating the partition, it worked fine. I could then toggle back and forth between the stock and Allicance. I did howerver just flash the stock slot to see if that resolves the issue with Allicance settings stop working error when i click on some customization options in the settings. I’m using AT&T Galaxy s5.

    • justme says:

      That did appear to resolve 2 issues. Issue 1: when trying to reboot, it would just hang and i would have to remove the battery. issue 2: That also did resolve the issue with Allicance settings not responding from what i can tell. I will now delete the Slot 1 ROM. Still having an issue with installing the Dialer though. I can install the stock modded one, but not the Black Glass theme…

  20. John Marnell says:

    FINALLY FINALLY FINALLY! SO EASY TO DO! Thanks for this amazing and easy to understand way to do this. This was so easy to do!!!!! I been trying forever and found this. Thanks so much!!!!

  21. James says:

    Rooted my At&t GS5 per your instructions using towelroot, then installed safestrap and made a backup. Worked like a charm! The whole thing took less than ten minutes, and now I’m waiting for some good TW based ROMS to try.
    I always used your guides for my GS3 also, never had a problem.
    Thanks for posting such helpful guides!!

  22. Christian Robles says:

    So I rooted my AT&T Galaxy S5 SM-G900A and aside from the ROM you used in this current video, I can’t seem to find any other ROMs. However, I noticed you said that T-Mobile ROMs can be used. That being said, the website has CM11 ROM that is compatible with T-Mobile’s SM-G900T yet says it doesn’t work with SafeStrap recovery so I am a little confused lol. Please clarify and I apologize for being a noob. Haven’t rooted any of my devices since my S3.

  23. aleoni says:

    I have an AT&T Galaxy s5 and want to know if it is possible to flash it with a Verizon ROM … I would like to use a Verizon SIM in this S5… is this doable? If so which Verizon ROM would you reccomend?

  24. Fabio says:

    Hi Max Lee!
    I’m trying to find this custom rom the days and I can not. My machine pe one S5 G990A, but has no language in PORTUGUESE. I know that the ROM has G900F that language! You could show me a link to download this I realize CUSTOM ROM being used in the video?

  25. Eduardo says:

    Hello, I have installed this rom and its very smooth and fast, but now the computer does not recognize the cellphone when I connect it… Do you have any solution for this problem?

  26. blizzy mobile says:

    • Sylent S says:

      -No data issue –

      I had that issue before, try installing a widget from Play Store that turns your data “on” and “off”? That was the fix in my case. I flicked it on and 4G was enabled.

  27. andrew says:

    I have a Verizon s5. I have tried to make towel root work but have had no luck. Is there another way to root my s5 without using towelroot?

  28. steve2 says:

    I have a Verizon galaxy s5 fully downgraded back to complete stock NCG kernel and 4.4.2. I have root and still can’t get safe strap to work.I have the files from xda that claim to be for the ncg kernel.

  29. steve says:

    Don’t know if that comment went through. I have a Verizon galaxy s5 fully downgraded to ncg kernel and 4.4.2 kit Kat. I cannot get safe strap to work. I have used towel root and installed busybox but no matter what safestrap no worky

  30. Assaf Aviv says:

    Hi, Can I install in the same way that described below – the CM12 rom (Nightly) of CyanogenMod on the SM-G900A?
    Thank you very much and have a nice day 🙂

  31. Alex says:

    wi this work if you have the samsung retail mode stuck on it?

  32. clint says:

    this is a great guide, but I’m wondering about something. When you install safestrap and a custom rom, what happens to the original samsung rom? does it still stay on the phone staking up space? I’ve been trying to get a clear understanding of this, because from what I have read the original samsung bloated rom takes up about 8-9gb. I’ll admit I don’t fully understand how exactly safestrap works, so I’m not sure if any custom rom installed would ‘sit’ alongside the original rom, or if you can erase the original rom and regain that storage space.

    Max! I know this is an old post but there’s a lot of us out there who have att s5’s that were unfortunately upgraded to lollipop. You are the mad root genius and we need you! My beloved g3’s screen busted yesterday and I’m working with this s5 until maybe the axon 7 comes out.
    I WILL DIE IF I DON’T GET ROOT!
    Also my wife might kill me if I waste any more time searching for a way.
    Please please help us! I specifically have the active, g870a on 5.0 with a 5.1.1 Ota pending. Att has further locked the bootloader since lollipop and we cannot use Odin to rollback even.
