Quantum ROM with Android 4.4.1 for Galaxy S3! [AT&T/T-Mobile/Canadian]

quantum-rom-galaxys3

If you are looking for a good Android 4.4.1 KitKat ROM for your AT&T SGH-i747, T-Mobile SGH-T999, or Canadian SGH-i747M/T999V, check out Quantum ROM.

Based on CM11, Quantum ROM brings you a custom-tailored Android 4.4.1 experience to you along with some cherry-picked features from other custom ROMs also.  One thing I really like about this ROM is that it’s quite fast and does even come with its own Quantum kernel to boost your battery life to the fullest while giving you added performance.

You will also find additional UI customization you can do for your status bar, quick toggles/tiles, notification bar, and lockscreen, that may get you a bit more customization than a stock CM11 ROM.

Also, camera/camcorder works flawless out of the box with even photo-during-camcorder feature working which you can easily upgrade to PhotoSphere camera (as it doesn’t come with it).

Overall, I do highly recommend Quantum ROM for those of you with AT&T, T-Mobile, or Canadian Galaxy S3 as it performs great and battery life is solid while everything works out of the box.  So, definitely give this guy a go over the week(end) and do let me know what you think!

Download:

Download Quantum ROM for Galaxy S3 (For AT&T SGH-i747, T-Mobile SGH-T999, or Canadian SGH-i747M/T999V)

Download Android 4.4 Gapps (DO NOT USE OLDER 4.3 Gapps you will FC!!!)

NOTE: You need to update you CWM Recovery to v6.0.4.3 or higher OR also update your TWRP Recovery to v2.6.3.3 or higher.  You can use either ROM Manager app or Goo Manager app from Play Store to update.

To install, reboot into recovery, make backup ROM, wipe data/factory reset, install ROM, install Gapps, and reboot.   (If for some reason you end up in a bootloop, reboot into recovery, go to Advanced Wipe for TWRP or Mounts & Storage for CWM, format/wipe /system, then re-install ROM.)

Note: CM11 does not have root enabled by default but you can easily enable it for adb & apps in Developer options.  If you do not know how to do this, see this video.

    You’re saying to get TWPR 2.6.3.3 or higher, but the latest for d2att is 2.6.3.1. Is this a misprint perhaps?

    Hey,
    Thanks for your website, I use it for all my roms. I tried installing this rom, I’m using cwm, I cleared data/factory wipe,davlick wipe, cache wipe, format system, install rom from sdcard, it says: “finding update package….
    Opening update package…
    Installing update….”
    then a progress bar shows ups, after a few seconds it says install from sdcard complete. I then install gapps 4.4, it says android 4.4 ROM detected and then installs gapps. I then reboot system and it loads my old rom splash, illusion 4.2.2 and then gets stuck on loading. I am used to seeing more info and text when installing a ROM, as opposed to just “finding, opening, installing”, is there something missing? Any help would be appreciated.

    Hey Max,
    My Data is only 3G not getting 4G / LTE. Tried default APN (pta) which only gives me signal, no data, and the Wap.cingular APN and phone APN only give you me 3G. Also change preferred network type to GSM/WCDMA/LTE which did not help and then tried *#*#4636#*#* and change it to GSM/LTE and waited more then 30 min, but still no luck. And yes i do receive 4G/LTE in my area and have not run out of data either. Any advice or other options i can try that will make my 4G /LTE work?

    • Kevin H says:

      Try flashing a different modem/radio. You can get the flashable modems to use on ODIN or zips on xda. Need more advice let me know.

  4. JAmes says:

    Can this be installed using Odin instead of CWM?

  5. James Duncan says:

    Installed the app and gapps and it works great.

    My only question is, why can’t I find the zip of the rom and gapps to delete it? I cannot see it with android file transfer or file manager on the phone – however I can boot into recovery and see them when I select install file from zip.

    Any hint?

  6. Arthur says:

    I used this rom and It worked good…but when I tried to make a videocall on LINE or TANGO or SKYPE,, It doesn’t work =/ … I really liked it…

  7. JESSE ONEx says:

  8. john says:

    I root my galaxy s3 4.3 Canadian version. I try to install super user but it said install aborted. I think because of the knox security on 4.3 block me to install whatever from my zip file what can I do now. Please help.

  9. john says:

    Is it possible for me to downgrade to the old firmware. will it brick my device.

  10. BenT says:

    This ROM does not work with the T-Mobile Galaxy S3 (SGH-T999).

    • Chris says:

      It works on mine but it registers as an I747(att). The only glitch I’ve seen is the email app closes when I try and add my exchange account.

    • Kevin H says:

      I just flashed this ROM on my t999 and works fine what are you using to flash, cwm or twrp?

      • BenT says:

        I used TWRP, that may have been the issue (it simply refused to flash, saying that the image was intended for an ATT). Might try using CWM over the weekend when I get some time.

  11. Alex g says:

    Installed rom works beautifully no issues with one exception. Tap and Pay does not work at the terminal.. Google wallet simply doesn’t connect with it… I have a T-Mobile phone . I know they are blocking Google wallet from their phones because if their ISIS. But I thought rooted phones should work even if their are on T-Mobile. Is this is a rom issue or T-Mobile that is giving me hard time?

  12. Eric says:

    I haven’t been able to get this installed on my t999. It also says intended for AT&T. I’ve searched and just can’t find a fix at all. I’ve done everything suggested and requested that I’m aware of. I tried rom manager and then just used cam to flash after cleaning everything plus some. What’s up with this, please any help anyone that is running this on a T-Mobile t999

    • Eric says:

      Has anyone really successfully put this on their Tmo phone? I’m not a noob but not an expert either and I just can’t figure how to get this on my t999. Please, had anyone got any helpful hints? I’m using the latest version of commission. I also tried twrp and still nothing. How do you get around the rom pushing the issue of it being for AT&T?

  13. Tony says:

    Max, I can’t seem to find the AT&T version of CWM 6.0.4.3 as you have indicated that we need for the upgrade. Can you post a link to it here?

    Thanks

  14. Larry says:

    Max…I have used your site for my S3 and S4. I love it. Now I have a challenge. I just got a new Tmobile S3 and it is a SGH-T999L and CWM says they don’t have a version for it. I have downloaded and installed everything from Wicked Rom to Quantum 4.4.1 and nothing works properly. I had wicked rom before on my old S3 and it worked great. On this phone, I get no 4G data. It is an LTE phone. Any help? Thanks.

  16. Jason says:

    Why do I have so much trouble installing any cm 11 ROM ? I do everything right and after I click install ROM (CM recovery 6.0.4.3) I always get a status 7 error no matter what i have done please help!

    • Dave says:

      I was having a similar issue. I finally looked closely and it told me that the image I was trying to flash was d2att, but the device was d2mtr. Mine is a Canadian Rogers phone SGH-747, which I usually use ATT ROM’s for. The MTR worked for me, in this case.

      • Dave says:

        Update! It turns out that after I flashed CM11 D2MTR, the phone portion did not connect to the network. Back to the drawing board…
