I installed the 08/06/15 CM 12.1 nightly using TWRP on my VS980.
The problem is that I only have an LTE connection for a minute or two before it drops to 3G. Switching airplane mode on and off will get me another minute or two of 4G. This occurs no matter where I am, even when there is full LTE signal strength.
I restored the backup I made before I flashed the new ROM (which unfortunately didn't include the old modem) but the problem persisted. After that I flashed back to CM since the problem occurred either way. I also notice that my text messages take longer to send now.
I think it's probably the modem, especially since it's the only thing I for some reason decided not to backup before I flashed. When I look in "about phone," the "baseband version" is "unknown."
I tried Googling which modem to use but had no luck. Do you guys think this is the problem, or something else? Thanks in advance for the help.
