sjravi, perhaps these NV backups would be of interest for comparison purposes. I got these in the course of trying to flash back the stock modem on my T889V, which it currently bootloops with.
My phone is currently stuck with the I317M modem, has 850, 1900 and AWS HSPA in addition to LTE. Barring any inaccuracies in the Ookla Speedtest app, it also has DC-HSPA. (The phone clocked at 26 Mbps on HSPA during one of my tests.)
There's a stock T-Mobile T889, stock Videotron T889V and my post-repair, I317M modem-running T889V backup in there.
