OK, apparently after this flash you're supposed to have PRI version 2.34_003 according to screenshots. I flashed it via the SD card, then flashed back to my preferred VZW radio 1.03.09 - and I still have PRI version 1.47_003. How do I get the newer one?
Honestly, I don't even know if the newer one will help my reception but I have to try everything. Thanks.
