    • Bond.

      I had Cyanogen mod on my S3, it ran like ass so I’ve taken it off and put the original Samsung Firmware on it, and it’s even worse, won’t stay on for over a minute without freezing. Going to send it to Samsung hopefully they will repair it.

  • a normal guy

    • Mahesh Makvana

      Did the procedure go well?

  • Zach

    Can you use this for cricket?

    • Nop, you MUST not use this for Cricket as it may brick your device. It works for the MetroPCS variant only.

  • I done all but now i can not make calls or send sms. network not registered error please help me!!

    • Mahesh Makvana

      Did you choose the appropriate firmware for your device? Sometimes choosing a firmware that’s not available for your location can cause this kind of issues.

  • Fah1m

    does this work if u have upgraded to jellybeAN

    • Mahesh Makvana

      It doesn’t matter what Android version you have, just select the appropriate firmware from the source page and flash it on your device using Odin.

      I guess you’ll have the Jelly Bean firmware available on the Stock Firmware page.

    I am stuck on metropcs logo screen after running firmware I noticed afterward region is Canada (metro pcs), is that why this happened, is there a firmware for USA metro pcs.

    • Mahesh Makvana

      You should have selected appropriate firmware for your device. If you’re in the US and selected the Canadian firmware, that could be the reason of your device being stuck at the logo.

      Just re-flash the USA version of the firmware and you should be fine!

  • josue_

    just finished downloading the files and trying to unroot it.

  • josue_

    I did all the steps that was said to do and the phone restarts but stays on the screen with the metro pcs screen.. any idea what could be happening ?

  • Jenny

    If I turned off my device into download mode and it says custom is official, will this still work on my samsung galaxy s3 and I have 4.3 jelly bean? I didn’t root my phone, what I did was clicked settings, about device, and I did a software update from 4.1 to 4.3. Will it still work if I try going back to the official software. How do I do that?

    • Hi Jenny,

      This should work regardless of what version of Android you’re running on your device.

      Hope this helps!
