I got the 4.4.3 OTA today. I was hoping it would fix my signal. I had 0 bars with LTE , maybe 1 with 3G and 2 with 1x. I was able to connect to Data with LTE even with 0 signal bars. So now, I updated and I still have 0 bars with LTE, 0-1 bars with 3G and 2 bars with1x .. Connecting to Data I only get 3G no LTE.
I tried diabling band 26, that made LTE come on for a few minutes then back to nothing. I tied changing the settings
25-0
26-0
41-1
Still LTE came on then went back off. And everyitme I check LTE enginerring it says I am on Band 51 ??
