Ting Army, I need your help. Please help me bring my Samsung Galaxy SII Epic 4g Touch back to Ting!
My ~15 month old SGS2 (purchased through Ting) decided to brick itself. I have a thread here on xda developers  where I detail what happened to it and what I did to attempt to restore it, but in the end I think it was a lost cause. In a nutshell, I think the NAND memory went bad and I could never flash it back to life.
So, I ended up purchasing a used Sprint SGS2 on eBay with a broken screen and a clean ESN and swapped motherboards. However, the seller had flashed a Boost mobile ESN to this device. I have the original Sprint ESN (printed on the phone and the box) and I’ve been in contact with the seller and he’s sent me a few files and links to the guide that was followed to flash the phone to Boost.
At this point, you’re probably thinking that I should take this up with the seller because the phone was not what was advertised, get my money back and find a different device to steal its motherboard for my frankenphone. That’s true, but the seller seems like a nice guy and he’s been really helpful trying to get me all the stuff I need to flash it back to the original Sprint settings. Plus I enjoy tinkering with things and want to see if I can get this working, because it seems like I’m so close!
I’ve been reading about the flashing process...saving NV items, data profiles, HA/AAA passwords, etc. The problem is I’m not sure which information is common to all Ting/Sprint devices and which data is unique to my device.
I do have my wife’s SGS2 on Ting that I can use to read info from, so I am hopeful to get network information that is common to all Ting devices that way. Also, the eBay seller did send me a file with the original Sprint HA and AAA password (which from researching I believe the AAA password is unique to my device).
Here  is the guide I’m going off of. It looks like there are several items that are required from the donor phone:
NV Files (step 2B):
Data profile (step 2C)
Data profile passwords
AAA password - unique to device
Can I read these NV files and data profile from my wife’s phone to apply to mine? Or are they unique to each device? Ultimately, am I on the right track here?
Thanks for your time!
