I am on a custom rom XXUGNG8 Base.
I wanted to try the matching modem so with odin I flashed the modem.bin (since I am on the old bootloader) and I have lost my 3G/LTE connection completely. It just won't connect. I've flash modems like this a lot of times and never had this issue. I tried flashing the old modem back, a full wipe and a clean install but I still don't have a connection.
It somehow feels like the modem isn't working at all. GPS still works.
Many thanks in advance for your help.
