TWRP isn't necessary if you find a custom ROM that does what you want in Odin format.

'mdm' is the modem - the thing that communicates with the outside world, wifi or mobile data.

Make sure that the version of TWRP you try to install is the version for the SM-G9650. It's not the same software for all phones. It's not even the same software for all S9+ phones.

Hi man. I have the same G9650, bought it from Claro, a carrier from Brazil. I tried to flash the ZTO Rom (no carrier firmware) and had the same issue as yours. I tried flashing the original Rom and the Samsung Pay, Banks, and every app that requieres any kind of security certificate stoped working. I reach the Samsung store here and they told me that the g9650 linked to carriers are unable to be flashed by others carries or no carriers roms. They change the main board of my phone, because I used Odin and an oficial rom, it dindt void the warranty. So, unless you bought an free-carrier G9650 you cant flash your device. I read the same in XDA.
