Sprint Galaxy Note 2 SPH-L900 (how do I reinstall Sprint PRLs & get rid of Page Plus & its Verizon PRL)
I bought a Sprint Galaxy Note 2 SPH-L900 not too long ago on Craigslist. Guy told me it worked with Sprint but he apparently flashed it to something that used Verizon PRLs (from what i've been told probably Page Plus). I recently tried to use Ringplus/Sprint with this phone but couldn't use it due to the PRL problem. When I try to make a call a robo Verizon operator pops up and I can't make calls. Of course, I can't get in contact with the guy that sold me the phone so im hoping you guys can help me get it to work with Sprint.
The MSL number has been changed to all zeros. And the dial code ##72786# shows "SCRTN" at the very top then just restarts my phone.
So I rooted the phone using this simple process. [SPH-L900] CF-Auto-Root
Then I downloaded SuperSU. Then tried DFS to change my MSL number back to the original number. But it didn't work. I tried PRL Helper, but that too did not work. Won't let me reset the PRL. So I unrooted my phone (or so I thought) and reset the phone to factory to see if that would work, and it did not. So I reinstalled the CF-Auto-Root and now even SuperSU won't work. Im new to all this rooting stuff. THIS IS FRUSTRATING!
My phone is running stock rom. Android version 4.4.2 Baseband version L900VPUCOH3. Build number KOT49H.L900VPUCOH3.
