2. Next you will need the download an Odin tar file. I used the K23 from garwynn from sxtp devs...When its done you will need to extract the files. You can use 7-Zip, WinRar, or anyone you want. There are several chooses, I used the Rooted-Restore.exe file. Open the Tar file and extract it to somewhere you can find it. I use my desktop to can it easy. You should see a new file called Odin-OC.

3. Now that you have that, unplug your phone from your PC and turn it off.... Pull the battery to make sure it off. Put your phone into Odin/download mode. To do that press and hold volume down and power at the same time.
4. Open the Odin-OC file on your PC and open the .exe file in it. Connect your phone to your PC. Once it connects, you should see a green box on Odin that say ROM and then a number. The number doesn't matter.
5. Click Start
6. Your phone will reboot when it is done. You will see a Sprint 4G boot animation
7. Next you will need to put a custom recovery on your phone. To do that, you have to opinions. You can buy Mobile Odin off google play which will support the developer, or you can download the lite version here.

8. Once you have Mobile Odin, you will need to download a custom recovery, CM 10, and GAPPS. I used AGAT v.6.8. as my recovery. If you use a different one, make sure it is a .tar file. You can put them on your internal or external storage on your phone, doesn't matter.

9. Open Mobile Odin on your phone, scroll down to open files, navigate to your .tar recovery file and open it. It should have the file listed under Kernal. I suggest having the Inject SuperUser and Mobile Odin boxes checked. It will make it easier to revert back to stock. Click Flash Firmware.
10. Your phone will boot into recovery mode when done.
11. From recovery select apply update. Navigate to your CM10 files and flash. once its done, flash your GAPPS.
Congrats You are now running CyanogenMod 10 Android 4.1.2 for the Samsung Galaxy S II Epic 4G Touch
12. To revert back to stock simply download the .tar file on your phone, open Mobile Odin, select the file and flash firmware....Just a side note, doing so will reset your custom recovery back to stock as well and you will have to go through the process all over again......
