Graviton ROM for Galaxy S4! [Android 4.4.2/NC8]


For this week’s Galaxy S4 ROM of the Week, check out Graviton ROM, available for AT&T, T-Mobile, Canadian, and GT-i9505.  Also can be installed on AT&T Galaxy S4 with SafeStrap.

If you are looking for a good, minimalist custom ROM on the latest Android 4.4.2 firmware, this is definitely a great ROM for that.  Based on GT-i9505 firmware, you will get goodies like Hotspot working out of the box (for AT&T and T-Mobile users) and complete removal of bloatware that may have caused lag on stock ROM.

Now, I hear from many people daily on how their stock firmware is laggy and really, the best way to fix that is by installing custom ROMs such as this Graviton ROM.

Graviton ROM also comes with some customization, allowing you to fully customize your status bar, battery icons, change clock position, and enable battery bar.  It also comes with App Ops, which allow you to set permissions individually for each of your apps.  For example, this may be useful when your kids download a game on your phone and it annoys you with game notifications, which you should be able to turn off with this feature.

Graviton ROM also comes completely themed in slight blue, and this is probably the closest you get to AOSP without actually installing an AOSP ROM.  For AT&T S4 users with SafeStrap, this may be a good deal since you can remove most of the bloatware and even use the KitKat launcher it comes with.  It’s not AOSP ROM but it’s close.

Overall, Graviton ROM is a beast when it comes to performance and also gets great battery life so if you are looking for such a minimal TouchWiz ROM, definitely give this guy a go this weekend and do let me know what you think!

Q: The ROM is not booting!

    • Leo says:

      Hi Michael,
      Try to do a full wipe of your phone and re-install.


      • mitch says:

        • Leo says:

  2. steeba says:

    Formatted like about 10 times…stays in bootloop…won’t load for some reason…was usin’ fenny for awhile…worked ok but was kinda slow, kinda tempermental…liked to freeze a lot and reboot outa nowhere…used all latest ROM’s and latest 4.4.4, lost GPS for MAPS on all of ’em…GPS came back w/fenny stock…

  3. steeba says:

    …sorry, forgot to leave model #…TMO SGH-M919…can’t get out of ‘bootload’ for the life of me ! Never had probs installing ur ROM’s, Max…this one’s a stickler…using TWRP, btw…any tips ?

    Thanx !

  4. Leo says:

    Did a fresh re-install got stuck in a bootloop.

  5. Lucas says:

    Yeah, i have a GT-i9505 and i am experiencing the exact same problem… reboots into download mode and stuff… tried several times and got the same results, coming from Carbon Rom after wiping data and cache, using CWM recovery

  6. evaldenis says:

    Hey, I’ve got the same problem on my I9505. If I am trying to install Safestrap version I got stuck on bootloop. If I am trying to install normal I am getting stuck with download mode..
    Please help

  7. steeba says:

    TMO SGH-M919…using TWRP v2.7.1.0…full wipes, full fac/reset even formatted data, all done several times…result, same bootloop repeatedly…

    Sorry for the hassle, Max…I’ve had virtually no prob w/any of ur ROM selections the past cupla yrs and I say thnx ! Been likin’ the idea of goin’ back stock via rooted…like the original (Sam) camera better, GPS/Maps works great (again !), etc…not as fast but livable…would really like to try Graviton just to get it up and workin’…never have had a ‘looping’ prob b4 on ANY of ur ROM suggestions !

    as always,

    • Max Lee says:

      Format /system not data and try re-installing ROM.

      • steeba says:

        …will do !


        • steeba says:

          …didn’t work…same ‘loop’…gonna try downloading Graviton again to my SD (had to re-install fenny)…maybe it’s corrupt, dunno…

          • steeba says:

            Well, did a new download of Graviton to my SD…did all the wiping, formatting & resetting possible on TWRP v2.7.1.0 before install…nope, same ‘bootloop’ prob…

            Was wondering if anybody has had success installing Graviton on their TMO SGS4 M919 ? If so, lemme know how ya did it cuz I’m stumped !! ;-}


  8. Paulo says:

    hey people same bootloop problem here im using th i9505 , it doesnt boot no mather what

  9. davidmarenco says:

    you never let me down in the past but im stuck in boot loop now. tmob sgs4 m919

  10. guido24 says:

    Same problem as everyone else. Boots right to “Downloading”. SGH-m919 tmo. Tried different versions of TWRP, reset, rebooted, wiped, formatted numerous times. No go. :/

    • steeba says:

      …as I mentioned b4…wonder what Max used to install it ? Enquiring minds need to know ! ;-}

      • guido24 says:

        Yeah, hopefully he’ll get a chance to revisit it. I just don’t have much time to troubleshoot. I installed the (should be what comes with the ROM), no luck there. I then tried a KT TW kernel and that at least got me to a spinning Graviton logo, but after 30 minutes of that spinning logo, I gave up. I just installed mahdi rom to get me going again.

        • steeba says:

          …pretty much ditto on this end guido ! I’m runnin’ Fenny on mine (stock ROM root)…what I like most ? stocker’s allow pics/vids straight to ur extSD…

          …all 4.4.3-4’s ? Gotta use SD file/trnsfr apps…pain in the a**, ya know ?!!


          • guido24 says:

            Yeah, the whole sd card thing is just frustrating. I could gripe for hours about it. Thanks for the heads up on Fenny, installed it last night…mahdi was FC’ing everything.

            • steeba says:

              Fenny’s cool rooted and generally works ok but what I noticed is that it inadvertently likes to re-boot, i.e., middle of phone call, etc…can’t have it all, rite ?!!

  11. Alex says:

    AAH, dammit. Would’ve loved to have this ROM. T-Mobile SGH M919 here. Ended up getting a status 7 error. Tried “remove assert line” advice but there are no assert lines to remove. Shame. Would’ve loved to have this one running. Going to try for Fenny but the instability complaint from ‘feeba’ about random reboots sounds disgusting. I just started playing with this ROM thing a few days ago and holy hell it’s stressful.

    • Alex says:

      Couldn’t get Fenny to install either. Same exact error. Seems I shouldn’t bother. No idea what I’m doing wrong. Guess I’ll go back to stock ROM and root it ._. Aye, this is stressful.

      • steeba says:

        …Fenny goes rite in ! Flash w/TWRP v2.7.1.0…effortless ! Btw, ‘Fenster’ hasn’t rebooted 2day…sometimes ROM’s gotta get ‘seated’ and then they operate ok…not sure what ur ‘remove assert line’ is…haven’t seen that one or ‘status 7′ error b4…like I mentioned earlier, try usin’ TWRP if not already…
        good luck, Al 1

        • Alex says:

          Wow, what a relief! I feel so foolish. I was using CWM before and I forgot to mention that. Hadn’t bothered with TWRP, even though I kept seeing people mention it. Managed to get Fenny running but Graviton was a no-go, despite doing the recommended wipes. Haven’t tried installing Graviton with a previous version of TWRP, though, so I might try that at a later point. It looks too good to give up on. Right now I just want a usable phone again. Your fast response and willingness to help is encouraging and much appreciated. That goes for the whole Android modding community, too, as far as I can tell. It’s awesome. Thanks again.

  12. steeba says:

    …no prob, Al…glad to hear u got it (Fenny) up and runnin’…in response to ur using different versions (earlier, etc.) of TWRP…did that…result: nada ! I’ve done so many types of wipes, formats & restore’s that heck, I’m gettn raw ! ;-}

    …wish Max (know he’s busy !) could at least drop us a line on how he installed Graviton…I’ve literally done ’em all to no avail…

    Keep ROM’n !

  13. Alex says:

    For those having trouble with getting this ROM to run on their SGH M919, have you tried flashing this ROM with a different kernel, like ChronicKernel? I was looking into how I might be able to get this ROM to run again and I saw someone in the Graviton XDA thread mention doing so, but I don’t remember what page it was on or if they were successful. Still interested in trying this one out, so would appreciate any replies from those with success.

  14. skumar says:

    I have loaded Graviton in S4-i337 (with TMO sim) and it works great. I had few hiccups, but after few attempts (just did a clean wipe), and was able to boot successfully.

    Now can Tether. Thanks for awesome Video.

  15. Alex says:

    There’s a new version of this Graviton ROM now…any SGH M919s out there who have installed this successfully when they were failing previously?

  16. Pranith Madishetti says:

    I’m trying to install this on my galaxy S4 SGH-I337 with safestrap. I flash the rom and all, but when I reboot it goes into the boot animation but then says “applcation installer has stopped.” did i do something wrong. I factory reset several times and then flashed the rom.

  17. pmk says:

    so in 6 months it looks like nobody was able to install this POS time wasting ROM. I too have a i9505 that had been stuck in boot after trying this crap.

  18. TeeShark says:

    This site is horrible. Do not attempt to download rom using links on this site because it will only install garbage on your devices/pc’s. They want you to jump through flaming hoops, naked and then sign a deal with the devil himself. I understand you must pay for your services somehow but all that ridiculous software apps to host a single a file. c’mon… back to the only source you need for android. xda… all other sites just copy from them.
