    Can this work on american s3s ? i have the sprint version

  2. Wifi hotspot feature not working. Phone reboots itself after some minutes. Moreover it is a rooted version. Rest all is fine. Pls find a fix for hotspot.

  3. “Applying this firmware update won’t root the device in any manner.” Are you sure about it? because after I applied this firmware, SAMSUNG Service Center says my phone has been rooted and warranty is invalid when I gave my phone over some battery charging issues.

  4. On my India bought Galaxy S3, I has this notification that update is available. After updating to 4.1.1. (Build No: JRO03C.19300XXDLK1, my battery life which used to last 18 – 20 hours has been completely destroyed. It hardly lasts 4 -5 hours nowand there is some strange daemon called UPSD which is consuming 45%.

    After killing REMOTE CONTROL, uninstalling AllShare etc etc the battery life has improved to 8 hours.

    However the screen gets hot and the SCREEN is consuming 67%.

    I am cursing myself for going in for the JB update.

    Can I roll back to 4.0.1 which was so stable and gave excellent battery life.
    Maybe I miss some minor bells and whistles. The much touted Project Butter is indeed noticeable after JB update, but maybe 5-10%.

    I am willing to sacrifice this 5-10% improvement for screen response time for 24-26 hours of superb battery life.

    Alternately, if it is not possible to downgrade, WILL THIS 4.1.2 Multiview Powered XXELK4 firmware package SOLVE my batter drain issue?

    Please advise ASAP
    Please advise ASAP

  5. The instruction to enter the download mode is totally wrong.
    Please correct.
    Otherwise the update is working fine.
    Good job.

  6. can i update this version directly on my I9300 containing XXLH1 as baseband? please reply

  7. hey people. i’v got the aussie version it says gt-I9300 in the model number in the about device. Rom went on fine and most things seem to work but the microphone doesnt work during calls. works on skype, works with voice recordings etc. if someone calls me the speaker doesnt work either. tried hands-free and speaker phone doesnt make a difference.

  8. Hi … is wi fi hot spot working on this version?

  9. is it already rooted?

    • no, its not the rooted one

      • mufaddal cementwala

        then sir why does it have Super User application which works and why does it say custom and not official samsung in downloading mode and also showing custom binary count = 1 and also upon checking for updates on samsung account, it says “modified”. or u can just download root checker from google play and check. what this is, is a pre rooted odin flashable rom. if i had checked XDA before i couldve been saved but now as i cant even go back to 4.1.1 official or any other offical to un-root my phone, im stuck. thank you.

      • it is pre rooted!!!!!!!!

  10. mufaddal cementwala

    hello. this is a rooted rom and has also made my binary count to 1. and shows custom on recovery. this has void my warranty i didnt want to root my phone and therefore tried this rom as YOU CLEARLY MENTION that it wont root my phone. and now i cant go back to unroot. tried flashing with latest 4.1.1 I9300OXADLJ4 (BTU) but isnt working. phone gets stuck on samsung logo. please help urgently!!

  11. Hi guys, awesome job.. keep up the great work.
    Id like to know if any updates done to the S3 FAMILY APPLIES to my SGH-I747M from rogers and if their even any updates for it yet

  12. Can I use this on my att gs3

  13. will this work for thr ATT Note 2?

  14. I’m curious about the portability of this firmware. The article refers to the Galaxy S III throughout. However, it’s specifically referring to the I9300, which is the international model with a different CPU. Are you stating that this update will only work on the I9300 & no other variants of the GS3?

  15. installed multi view version, very stable. no force closures. but when I useWi-Fi hot spot, mobile starts rebooting itself after some minutes.,otherwise perfect
