Android 4.3 ROM MJC + Root for T-Mobile Galaxy S3!


For this week’s T-Mobile Galaxy S3 ROM of the week, check out the Android 4.3 ROM with root.

Based on the leaked MJC Android 4.3 for T-Mobile Galaxy S3, you can experience first-hand on what’s coming with Android 4.3 for T-Mobile S3.

You may have tried the AT&T version from couple weeks ago but of course the T-Mobile version if much better for those of you who also need wifi-calling.

This ROM is pretty much stock except for some goodies like root, Flash Player, wifi band switcher added and best of all, it’s Knox free!

Samsung has been pretty dumb about putting Knox on older phones like the S3 as it has no real added benefits for regular consumers, they should only put Knox on business phones, which is its intended application.

But no worries, flash this ROM and you will have the latest Android 4.3 without the stuff you don’t want. So, give it a go this week(end) and do let me know what you think!

    Hey Max, thanks as usual bud. Have a question for you. In other model’s even with the 4.3 update I was able to access the modem settings *#7284# to enable the 1700 T-mobile band on my ATT devices, but with this update for the S3, I have I747, the entry takes me to the menu, but the USB settings option is missing. Any ideas on how to go around this to enable the T-mobile band on the TW 4.3 for S3 ?

    Thanks in advance.
