Excuse me, I'm a little noob. What Radio Modem/Baseband is for?
I'm updating from RR 6.1 to RR 6.2.1 and I'm reading about a lot of issues with Wi-Fi and Bluetooth in this Rom Version, does flashing a new Radio Modem/Baseband correct this? I can flash any baseband or depends on the Android Version?

Had to open up phone to change the battery over the weekend; since then, I've noticed the phone can only sustain a 3G/H+ signal. I've tried the fix cited in the first post several times, and I've tried flashing several basebands several times, all to no avail. At best, after trying the fastboot fix, I get the 4G to hold for a few seconds at start up before it drops back to 3G.

I noticed three tiny gold clips falling around whilst changing the battery and suspect this has something to do with it. That said, the problem persist even after replacing the missing ones with those from another phone.

So, any idea what could be causing this?
