2G-4G Working / 3G Not Working - Galaxy S 4 Q&A, Help & Troubleshooting

Does anyone have an idea?
Phone: GT-I9505

Is the phone running a stock ROM? Running the latest bootloader and modem? When did this start happening?

Yes, phone running a stock ROM (I9505XXUPQG1_I9505NEEPQG1_I9505XXUPQG1_HOME.tar.md5). This started about 3 years ago.

Wow, that is a long time!

Android 4.4.x

Hi,
I've got an sgs4 lte international version. I've tried to install every single android 4.4.x and all goes fine but after some time I cant recieve call, sms not working, phone reboots etc.
Everytime I did an installation I've made a full wipe.
Am I doing something wrong or are you guys facing the same?

Note: Omnirom working good but the only issue I am facing is that is eating my battery.

I'm using broodplanks aosp and it's amazing, no reboots no problems.

Need help, Baseband version unknown

I have a n9005 with knox set. It's running omega rom version 21. I haven't updated modem for a long time and the modem version was XXUENA2. So I thought oh it's about time to upgrade that. Then all hell broke lose.
I flashed to the latest DXUGNH1 and it was ok, but after rebooting the phone, I lost mobile data while voice was still ok. So I flashed again to XXUFNG2. This time the baseband version and IMEI number became unknown.
I then tried to flash to some other version and flash back to the old na2 version but nothing worked. I even tried "Fix Soft Brick Loop_ EFS partition" script thinking it might be an EFS problem but that didn't help either.
Now I'm sitting here trying to download a stock samsung rom to flash. Will that help, I don't know...
If anybody has any idea, please let me know. I'm desperate to get it fixed.

Thanks for the tip guys. Just before I go and download it, I just want to know whether there is a particular reason for flashing that version? Because I flashed NE3 official just now and the baseband is still unknown. If that's the case, will NG1 work instead? Hell, I'll just do it anyway and see I guess. Thanks again.
Your bootloader is new, and old modems not working on a new bootloader
sorry for bad english
I have the same problem, did you make any progress? ty.

So my modem is funked!

Hi guys, so I deccided to update my Kitkat to the new Lollipop. Biggest msitake this week. Its been 4 days that I've been tryign to fix this with no luck.
So I lost my LTE connection and I cannot get it back. I flashed so many modems and bootloaders with no luck. Some will give me 3g but never LTE even though the modem says LTE on it. Random reboots. Can someone please help!?

It says "Connection problem or invalid MMI code"

Can you please elaborate a bit? What happened? I flashed a custom ROM why did it do that?
And where do I find a stock Lollipop ROM?

1. This seems problem of the custom ROM. You can ask in the correct thread of the custom rom or simply flash stock lollipop (step 2).
2. HERE.

There is no Lollipop for mine. There is only 4.4.2? What do I do here?
And isn't there a way for correcting this without reflashing stock ROM?

You can flash UK Lollipop firmware if is unlocked. They use the same Bands for 4G:
- Australia -> 4G LTE Optus 1800/2300Mhz.
- UK -> 4G LTE 800/1800Mhz/2600Mhz/3500/3600Mhz.

What Kind of fail? Error message?
if you have updated to "coj5" or newer builds of 5.1.1 then you can not go back to kitkat or even previous builds of 5.1.1 or 5.0.1. thats why you get "failed" error in odin. unfortunately there is no way to downgrade as of now because coj5 locks the bootloader.

Damn I just downgraded a few days ago with exactly the COJ5 version. I've also heard that some people can't downgrade but it seems like I never had a problem with this.
Maybe if i had such a problem I would try to install a custom ROM / other bootloader with Odin first to see if works with a stock kitkat rom after.

looks like your baseband got messed up, download this latest firmware for this tablet and install it using Odin
