How to Enable OTG USB Host on Rooted T-Mobile Galaxy S2! [SGH-T989][Zedomax T989 Kernel]

Well, it took me awhile but I did get OTG USB Host mode to work on my T-Mobile Galaxy S2, you can now connect USB peripherals such as your USB Flash drive, hard disk (powered independently), USB Mouse, USB Keyboard, and much more.   Or you can even charge your other USB devices off your T-Mobile Galaxy S2 in an emergency.

To get it working, simply download the kernel zip file below and flash in ClockworkMod Recovery(CWM) just like a ROM except no wiping needed (just flash).

You will need an OTG USB host cable, you can buy one on Amazon or make your own OTG USB Cable.

    It enables USB OTG on Galaxy s I9100 but disables phone. USB storage do work but phone can’t find a cellular network and you won’t be able to call any number. I tried it on my Galaxy I9100 with MIUI Rom. If somebody understands how to make it work with I9100 with MIUI please help! Thanks!

  • daniel.r

    hey, here is an interesting tidbit of info someone might find usefull, i have a prepaid tmobile sim laying around, well it was from the very phone that i traded in to help me get my s2 lol. anyway, i put it into my s2 and now it is a prepay phone. same phone number as my old phone and everything. in phone info under settings it still said i had my phone number that the phone came with so i sent myself a txt using an app and sure enough it was my old number. so i guess all a person needs is a tmobile prepay sim and a prepay plan to switch. btw im running the malice rom and found a few bugs and would like an email address or something to report my findings.

    Does it work on Darkside ICS for Tmobile (4.0.3)??

    • admin

      Not on ICS kernels, this kernel is for Gingerbread only.

      • Bob D.

        Is there a way to enable OTG USB for ICS?

        • mnewman

          All the ICS roms that I have tried, it works on.

          • mnewman

            NOT THE KERNEL, but OTG does without doing anything extra. I bought an adapter from Amazon, and have used to numerous times with ICS.

            • Bob D.

              Great! Thanks for the help!
