[Q] NEWB Q: How do I determine which modem I have ?

Do as @milkybarkid suggested. And since you've flashed JVB recently then your modem is JVK I believe.

I got the N910T. Can I use any baseband?

I have the T-mobile N190T Note 4 when it first came out and I bought it the first week of it.
Can I flash any baseband on it as long as it is for T-mobile? Can I use COG2 or any others?

My N910T is currently on COG2 baseband, bootloader and rom which I got by ODIN flashing. In dev forum, I saw people upgrading from COG2 to DOK2 (latest) by flashing DOK2 baseband and bootloader, then flash DOK2 based custom ROMs and they worked for them. So I think you can try the same to see. Hope that helps.

Uknown Baseband - Can't downgrade modem to repair IMEI

I'm using a Galaxy M20 (m205f). Trying to root it, I somehow messed up the radio and efs partitions. Tried to install the latest stock Rom and it updated the binary from U4 to U7 with a null IMEI and unknown baseband. The IMEI repair softwares need the modem and the modem version presently is of U7 binary which is pretty recent and no IMEI repair tool supports this modem version yet. Is there any way I can downgrade the modem? There's no lower Android version and no combination file for the U7 binary on the internet so I'm stuck. Can I somehow put an older CP/Modem (from lower binaries) and make it work with the latest firmware?
