Dirty Unicorns ROM for AT&T/T-Mobile Galaxy S3! [Android 5.1.1]


Looking for a fast and stable custom ROM based on Android 5.1.1 for your AT&T or T-Mobile Galaxy S3?

If so, check out the latest Dirty Unicorns ROM, which is an excellent custom ROM based on the latest Android 5.1.1 and brings you a high level of great customizations.  Camera works great out of the box (I recommend the Google Camera on Play Store so you get Panorama, Lens Blur, and PhotoSphere modes) along with excellent navigation customization where you can customize all of your buttons (including Home, Back, and Menu buttons with short, long, and double-press) or even disable them altogether and go with soft navigation buttons, which you can also customize with your favorite shortcuts.

    OK, So sorry to ask a stupid question but don’t want to brick my phone because I’ve done it before & it SUCKS……I’ve had this AT&T I747 for a while and rooted it along time ago but really didn’t do anything with it. I really want to upgrade to an awesome new rom but am currently on a 4.3 build, baseband version I747UCUEMJB….I’M NOT SURE IF I’M USING SAFESTRAP or NOT……Can I install THIS ROM & if NOT, which would be an awesome alternative?? Thanks Max for Ur help…….Vince from Cali…..

    I Have an Australian i9305 S111 LTE, do these roms work with the international versions? Definitely don’t want a brick.

    Does this rom unlock free hotspot

  7. Alen says:

    I installed it and everything ran great on my i747. I did this because I bought this phone and when I put the sim card in I got a message “SIM network unlock PIN”. I thought maybe installing this rom would eliminate this but it didn’t. I tried purchasing the unlock code on ebay but for some reason it doesn’t work. Some one said it’s because I need to be in stock 4.1.1. Any truth to this??? I tried but since installing this rom I can’t seem to go back using odin or cwm. Can anyone give me advice???

    Can anyone tell me how to go back to 4.1??? I’ve tried using Odin and it failed and using CWM and that got aborted. I need to go back to Unlock my I747. Any help please?

    Hello, this ROM is fast and stable. Only issue is that it is dropping cell signal every 30 mins for brief period and restores back, did any one have this issue and what is the fix?

    Hey I installed this ROM and it works perfect. Only thing is that my soft keys (back and home buttons ) vibrate but not light up. I can’t seem to fix it. Any suggestions?

    Wow…..excellent ROM for S3 AT&T version. Everything works out box. Snaaapy……Snaaaapy.

    1. Still 1GB ram is left after installing OS + Apps. Total memory is 1.8GB RAM.
    2. No Lagging – Android 5.1.1 is awesome —–
    3. Dirty uniconrns – provides extra optimizations. All are good and appropriate.
    4. Camera is Good – no issues.

    Kudos to Dirty Unicorn team. I have tried CM 12.1 – but data was NOT working .This ROM resolved the issue.

      I had the same thing what I did was a wipe to install a new rom and then don’t download the latest ggappps coz the latest gapps causes the error is my guess stilll trying the older gapps and will tell what to do. 🙂

    Had a problem with mms texts after installing the DU ROM and recommended Gapps on ATT. It turned out that the problem was that the ATT LTE pta APN had the Authentication type set as “not set”. When I changed it to “none” as shown in the”How to Fix 3G/4G LTE Data by Manually Setting APN on Android”, the MMS texting started to work!
