Fixing Galaxy S4 Android 4.4 Network Problems

[Anon]

Decided to make a post helping people on how to fix this as I spent a few hours myself tackling the issue.

What this will fix 100%:

Network Losses (e.g joins 48 network then losses connection after a bit)

2g Only (no 3g internet or h+)

Backstory:

Earlier today I updated to android 4.4.2 on my Galaxy S4, was happy with the UI and the updates until I found the major issues with it. If you own a pre nexus 5 device, you will have the old modem software on your device and need to update them, this is the issue.

First what you want to do is go to this post:

http://forum.xda-developers.com/showthread.php?t=2544474

and download the new 4.4.2 modem (or what ever the newest one is)

Use Odin to flash it into your device, after reboot all the issues will be fixed.

Make sure you also put in the Access Point Names information, they can be found in this post:

If you have any question, post bellow, I'll be glad to help.

I presume that this is specific to the Samsung Galaxy S4?

If so you should probably make that clear in the thread title.

Just in case anybody with another device tries to flash the modem firmware and bricks their device! 😮

Yes to the particular links but the method works for all devices you just need to find the modem flash for your particular device, anyway updated OP, thanks.

Did it ever work?
If so what changed recently?
When you scan for networks what carriers do you see?
Do you see 48 and can you connect to it?
Do you have data roaming enabled?

Hope this helps.
