I have a Galaxy S5 that I recently installed a custom ROM onto. I installed Bliss Marshmallow works fine except no LTE data. Occasionally, I see the 3G icon pop up, but it only stays on for a few seonds at best. I tried to do a carrier reset, but nothing happens when I enter the code into the dialer. In addition, there is no menu for APN settings. Is there some way to get LTE working or do I need to switch back to my old ROM? Thanks.
