The Android 4.1.1 Jelly Bean update for the T-Mobile branded Samsung Galaxy S III T999 is almost here. After a brief appearance of the Jelly Bean update for GS III in a video and after seeing a leaked build for the i9300 model through XDA forums, it’s finally the time for for one of the US editions of the Galaxy S III.
XDA forums member LuffarJoh has released the possible early OTA update file, carrying a new firmware version that bumps the handset’s software version up to v4.1.1 aka Jelly Bean. This build is JRO03L and nearly complete, but almost certainly isn’t the final version. Therefore, you can expect a few small issues in this leaked firmware update. According to the users’ reports, you won’t be able to make Wi-Fi based calls through T-Mobile’s service and a few bugs need to be sorted out with the stock browser and video player and this build breaks root. It appears that this build is carrying “Google Now” as shown in the screenshot below and you need to check it if it working or not.
Please note that if you are looking to flash this build on your handset, you will need to make sure you’re running stock build T999UVALH2 first. If you understand the risks but want to give it a shot, go ahead and follow the source link below for download, instructions on how to flash this build on your T-Mobile’s Galaxy S III handset.
