I was hoping/thinking that the N910V and N910T were basically identical hw, and the carriers decided which CDMA/GSM/LTE bands to lock/unlock in firmware. Again, an assumption, but was hoping if I could get past the odin signing formalities, that if the hardware were identical, the firmware (modem/baseband) could possibly work(mostly). If you or anyone else knows from experience that it doesn't have a chance on an N910V, I won't waste any more effort.
But I will say this much, with this ROM:
trltetmo_N910TUVU2EQI2_Stock_Deodexed from thread:
★Stock Deodexed N910TUVU2EQI2 Rom★ Read below "BEFORE" downloading, flashing, and posting questions.... ...REMEMBER... I am not responsible for anything that happens to your device, if your SD card goes dead, and everything else! STOCK...
on an N910V, with a T-Mobile SIM in NJ, USA,
The cameras work.
WiFi/WiFi calling works.
4G/LTE works on Band 4, including data.
(would love to know how to enable more bands...)
VoLTE works, but after a reboot, or any calling mode change, I lose it and have to bounce the radio w/ LTE Discovery app to bring it back.
The issue is that I need this functionality, if possible, on my other Note4 w/ MODestROM 11, my highly tweaked daily driver for the past three or four years. Getting all of that over to and working on the test phone will not be trivial.
If I can't install the newer modem, I'm hoping maybe a phone app transplant might at least get the MODestROM 11 phone to the point where the TM-ROM'd one is now, which is probably useable. Everything is working on MODest w/ a T-Mobile SIM, EXCEPT VoLTE, and I have tried literally everything w/ no joy.
Thanks again for your expertise.
