First, however, let’s see what pre-requisites are in order: fully charge the battery of your smartphone, turn on USB debugging, create a backup using our instructions and download Gapps archive (you must choose the file called gapps-jb-20130301-signed.zip) along with the CyanogenMod 10.1 RC5-Build Jelly Bean 4.2.2 custom ROM.

How to install CyanogenMod 10.1 RC5 on Sprint Galaxy S3

  1. Your part of the bargain starts now by you having to plug your handset to your comp with the USB cord that belongs to the S3 SPH-L710. The two zip files in the requirements should be on your laptop’s desktop by now; go there and copy them both so that they can be pasted to the smartphone’s SD card.
  2. Unplug the devices after the transfer is over, then power the handset off and enter it in Recovery Mode. This can be done if you remember to do as follows: press and hold, simultaneously, Volume Up, Home and Power; when you see the display flashing, you can let go of all the keys.
  3. Create a NANDroid backup now. To make that possible, you have to opt for Backup&Restore, wait for a second screen to appear and then choose Backup.
  4. Wait for the entire process to end, then return to the phone’s Recovery Menu where you will need to opt for Factory Reset/Wipe Data; when done with that, confirm the action by tapping on Yes and have patience till the wiping completes.
  5. After that return to the Recovery Menu, opt for Wipe Cache Partition, afterwards for Wipe Dalvik Cache and then choose Install zip from SD card.
  6. Now select the option saying Choose zip from SD card and find the CyanogenMod 10.1 .zip file. Have it flashed on the S3 L710 like this: choose it with Power, then confirm the installation (opt for “Yes” to do this).
  7. After the flashing is over, opt for Install zip from SD card and repeat everything from there onward (minus the selection of the cm-10.1.0-RC5-d2spr.zip file, since that’s already on your phone, so opt for the other zip file this time); this is going to help the Google Apps package flash on your Sprint Galaxy S3 L710.
  8. Opt for the phone’s restarting once you are back in the Recovery Menu after the two zip files are on the phone. Not more than 15 minutes should pass from when you do that till the handset is booted into the Jelly Bean 4.2.2 custom ROM CM 10.1 RC5. Now enjoy the experience!
