How to Root the Samsung Galaxy Attain 4G (SCH-R920) on MetroPCS

The Galaxy Attain 4G is a relatively new device available on MetroPCS and a mid-range phone at that – this makes it a low priority device for most of the devs.  But some owners of this device are not sitting quiet and due to their hard work, the Galaxy Attain 4G can now be rooted.  This post will show you how to gain root access, enabling you to use all those root-requiring apps and may be even flash a custom recovery and ROM in the future if the devs keep working on it.

I.  Before You Begin

1.  This procedure could result in you owning a very expensive brick, so be sure that you indeed want root access on your device before proceeding.

2.  The following procedure has been known to have issues when tried on a Windows XP PC; so make sure that you run it on a Windows 7 PC to minimize the chances of bricking your device.

II.  Necessary Files

1.  Odin 1.85.

2.  Attain-Rooted-Update.tar

3.  Attain 4G PIT File.

III.  Rooting the Galaxy Attain 4G

1.  Extract that you downloaded above to a folder on your desktop.

2.  Double-click on Odin 1.85.exe to open up Odin3.

3.  Click on the PDA button.  Navigate to the location where you downloaded the Attain-Rooted-Update.tar file from the above link and select it.

4.  Click on the PIT button.  Navigate to the the location where you downloaded the Attain-4G.pit file from the above link and select it.

5.  Make sure that repartition is unchecked.  This is important as checking this will most definitely brick your device!

6.  Power down your device.

7.  With your device switched off, press and hold the Volume Down + Home buttons and then press power.  Then press the Volume Up key to enter the Download Mode.

8.  Connect your device to the Windows PC.  You should see the ID:COM field light up yellow when you do this; if this doesn’t happen, it means that you don’t the necessary drivers installed.  You can download Samsung Kies and install it to rectify this problem.

9.  Your Odin3 screen should now look like the picture posted below.  Again, make sure that the Re-Partion tickbox is unchecked before you click Start!

10.  Click on Start.

Once Odin3 says “PASS” and your device reboots, your Samsung Galaxy Attain 4G should be rooted!! If you are in doubt though, the usual way to confirm is to download Root Checker or look for the Superuser app in the app drawer.

    will this work with the ver.FG02 update released on oct 18th?

    • Dax Krishna says:

      no, this will not work with the newer update!

      • Mel says:

        does anyone know if there is any root method out there for ver.FG02?

        • Jacob J. Walker says:

          I think I need this also, I just followed the instructions on my new phone, and I think I am partly bricked (I say partly, as I hope there is a solution!) My phone boots, but it just keeps saying that basically everything needs to forcibly be closed. Is there anyway to undo this process? (Maybe get the pre-root image for ver.FG02?)

      • as of dec 24 2012 did not work with fg02 good thing is all you have to do is re download and install fg02 if you tried

  9. ER says:

    maybe the problems is.. you unlocked the cellphone metropcs.. so right now you really can use the sim card slot because metro need cdma and the sim card slot its only for the 4g and the slot its ready for a really sim card 4g fully provider..

  10. LucasEnrique says:

    how long should this take?

  11. faith says:

    4g works all is good. thank you. the only problem with this is that, YES, this will root your attain and give you super user access. But.. because there is no custom rom for this phone yet you wont be able to really change very much.. after you root.. download titanium back-up, watch a youtube tutorial or two on how to use it and remove all the bloatware from your phone. rooting is the best thanks so much for this.
