[Sprint Samsung Galaxy S III] RootSuperSU:
1st let me just say I'm not a developer at all just someone who enjoys custom roms as much as everyone else here! I'm not very good at explaining things so please try to bear with me and try to understand this the best you can! If any real developers read this please help us by adding support for our device and if any developers can explain this better please do so! For anyone with the d2lterefreshspr (SPH-L710T Tri-Band) wanting to flash almost any Lollipop Roms made for the d2spr you can flash them! You might 1st have to unzip the rom and go to the updater-script and delete the 1st part where it checks the recoveries build to see if your device is the d2spr or the d2lte and so on. Then repack the rom back into a zip file the flash it in recovery as you normally would. Then once the Rom boots you won't have a baseband or service or anything but I will tell you why and how to fix this. The d2spr's modem-image file are labeled different from our modem! At the bottom of this I will show you the list of each modems links so you can see which 1s are different and what you have to delete and resymlink to get the Rom to reconize your baseband and get your service working! But using a file manager with root access navigate to the files in "/system/etc/firmware/ " and delete the wrongly symlinked modem-images! Once you have done that navigate to "/firmware-mdm/images/" folder and start symlinking the correct files to "/system/etc/firmware/" folder. After this you might want to modify the buid.prop and change all parts that say d2spr to d2lterefreshspr but only if you want. Once you have done this reboot to recovery and flash the Lte apn fix zip then reboot. Now everything should work with service and everything! I have tried this on the latest SlimLP 5.1.1. Beta and A..I.C.P. Lollipop and a few other Lollipop Roms for the d2spr. If you would like to download some of the Roms I have modified the updater-scripts so they will flash on our device and the APN zip I flash with a flashable build.prop I have already modified just send me a message and I will send you a link to my drive account. I'm trying to create a zip we can flash in recovery that will delete the wrong symilinked files and symlink the correct files to help save us the trouble of this process and for people that don't know how to create a symlink file! But as I stated I'm not a developer so I might be able to but if any developers that could help us by creating 1 for us please please feel free to do so and let us know! But take a look at the 2 lists of symlinked files and delete the necessary files and create the new symlinks that our device needs! If the files show the correct symlinks on 1st boot but you still don't have service click on the symlinks and view its details and you will see it'ssymlinked to the wrong files. Just delete all symlinks and create the correct new 1s.

Example of the d2spr modem symlinked images are:
