Restoring STOCK on Sprint Galaxy S3 device

[ryuja1]

About 2-3 years ago I used to be really into installing custom roms on this phone and what not.
Anyway ever since I've had this phone I've messed up the motherboard twice and had ended up
buying a replacement twice.

Model #: SPH-L710
Android Version: 4.4.2
Baseband version: L710VPUDOH1
Kernel version: 3.4.0-2851177

Ok here are my two questions.

1. I tried to update the PRL, Profile and Firmware while connected to my home wi-fi unsuccessfully INTERNAL ERROR 407.
Do I need to be on a data plan for this to work??
2. Would restoring the phone to stock do anything? I see many stock images for this phone but baseband version ending
in ND8. Would the ND8 image work on this device?

Thanks in advance!

What carrier were you on when you had service? Nd8 is for sprint. Yes it will work for that model. However nj2 is a little newer. Just don't try anything older than nd8, that is before Knox and will brick.
For example, do not flash anything from mk5.
Nd8 is fine (sprint)
Nj2 is fine (sprint)
Nj3 is fine (virgin/boost)
Ndc is fine (virgin/boost)

Oh1, is weird, some are for the triband. If you flash OH1, just make sure you don't see SPH L710T in the name anywhere. That "T" at the end means triband.
