Jelly Bean Update For T-Mobile Galaxy S III Leaks

While we’re expect Samsung to start releasing Jelly Bean update for their Galaxy S III models sometime after their August 29th Unpacked event, we haven’t seen a lot in the way of official carrier updates leak out, especially for T-Mobile.

This leaked build, JRO03L, is nearly finished but still has a few issues, mainly the inability to use Wi-Fi calling and that’s likely due to this file originating from Samsung and not T-Mobile. We first noticed the file hanging around on SamMobile’s website earlier this morning, but now an XDA-Developer thread is filled with folks installing the file.

One major warning before considering installation: You need to be running the stock build T999UVALH2 before attempting to install, which can be downloaded if need be. Otherwise the installation seems pretty straightforward with applying the Zip in your Recovery menu and then enjoying Android 4.1.1 Jelly Bean.

Disclaimer: Before considering using this, make sure you’re comfortable with the loss of your warranty and be completely familiar with everything involving rooting and recovery.

     What I don’t understand is why doesn’t the phone companies pay the people at XDA to get those updates working?  The updates would go out a lot faster, and developers would get some good money so that they can make awesome bloat free versions of those updates for everyone else.

    If only…..

      While it would be great if we got these updates faster, do you really not understand why carriers don’t pay people to develop “bloat-free” updates for their devices?

    • IRIE4IPIER

      I don’t think you understand the process. Samsung makes the updates quicker than people think, it’s just that not only Samsung but also the carrier tests the build thoroughly before sending it out to customers. While XDA does an awesome job, they can never release a stable build without source from OEM’s.

    I received an update this morning on my S III, and also the other two I purchased for family members. I wish it would of been Jelly Bean.  

    • MagentaMadness

      Yea, just a firmware update :(

      Still noticed if fixed couple things

    • JBLmobileG1

      I just received this update myself. So far so good… I haven’t noticed any differences besides the universal search bar, but not a big deal since I never used it anyways. I can’t wait to get Jelly Bean, although I plan on waiting this time around because I don’t want to risk not being able to update down the road after Jelly Bean. One thing I will miss is flash though. If they still will support it for PC they should still support it for Android.

        Flash still works in Jelly Bean. The web browser just need to update to make it compatible. Stock browser, Firefox, and I think Opera has flash working. Dolphin Browser disabled it. Not sure when they’ll enable it again.

    i want the jb update for my s2

    • MarcusDW

      Me too bro. Give it 2-3 months I say.

      • fixxmyhead

        well if ur into flashing theres aokp jb but i got tired of it cuz its missing features and the most important thing is it doesnt have touch to focus for the camera. that one right there took me back to a solid stable ics rom with FULLY working camera plus i really love touchwiz and the killer features. hoping for JB touchwiz soon

        • MarcusDW

          Yeah I never have and never will put a ROM on my S2

        • fixxmyhead

          why not? u could at least use offcial ones lightly tweaked (even with bloat intact) to avoid major bugs if thats ur concern.

        • Dumbazz

          So what if someone doesn’t want to root? Whydo you guys always takethat so personally?

        • fixxmyhead

          im not taking it personally i was just saying. the only reason i root are for ‘hack’ apps like wifi kill and network spoofer just to mess around and titanium backup to save my data just in case.

        • Dumbazz

          Same here. I rooted my first one and despite tweaking it to hopefully save on battery I never noticed a difference. Android doesnt need to be rooted any longer and despite all the cries the added tmobile software isn’t a big deal at all. You can disable that stuff anyway! 

        • MarcusDW

          I agree 100%!

    • Skip Bayless

      i hate my s2 ICS always crashes, makn me go crazy…cant wait for iphone5

      • fixxmyhead

        Oh God not u again. Stop lying .

        • Dumbazz

          I just sent back my S2 to tmo. After the ICS update I dealt with CONSTANT crashes! This despite having performed a factory reset! 

          Somehow I suspect more people are dealing with this as well. Having owned many Android phones it’s almost always inevitable that there are issues after an Android OS update. 

        • fixxmyhead

          nothing but ok’ness on stock though im not on it anymore but it was fine. i never had any problems. idk who these people are that have ‘constant’ problems on a update thats supposed to make the phone better. as if thats really samsungs plan to give u shoddy software

        • Skip Bayless

          thank you…totally agree.. i did factory reset and it still sucks

  • MarcusDW

    That’s sweet!!

    Been running Jelly Bean on my GSM Nexus for a while (sans root). Buttery smooth. So glad I dumped the G2X.

  • Crush

    Can they make it so it had flash

  • http://twitter.com/SParKlngCyaNide SparklingCyanide

    this is awesome news, but I’m just not Brave enough to try this out on my GS3.  

  • Whitney

    T-mobile is trouble

  • carkeeus

    Tried it on S3, had too many crashes and rolled back

  • Bill Smith

    T-Mobile took forever with there last update(almost a year for some) so I wouldn’t hold my breath for this one.

  • MA
