My fried bought a Galaxy S4 from AT&T when he was in US. While leaving the country he bought an unlock code from AT&T and unlocked the phone using the same in India. His phone was working fine initially. Then sudden signal loss started to occur and need to restart the phone to get the signal back. Tried using different Indian carriers and the same issue continued. Will I be able to solve this issue by flashing a custom rom into his phone? Do I need to take care of anything else, like the modem firmware or something. Attaching a screen shot of his phone details. Please help guys..

You could try reflashing the same MDL firmware first. If that doesn't work, then install TWRP and try the different flashable modems.

Thank you for the reply.. However we have already tried a factory reset.. Will it be a problem if I flash the modem firmware available in the Indian Galaxy S4?? The Indian version comes with an exynos octa processor instead of the Qualcomm one..

Doing a factory reset is different from reflashing the firmware. I don't think the other modems would work, but I'm not entirely sure. If they're recovery zips you could try, but if they're ODIN files it definitely won't work.

I have tried reflashing the phone with Odin. The device now has the latest Android 4.4.2 firmware from AT&T. It seemed to work fine after flashing. We got the network and were able to make calls as well. However after sometime the signal got cutoff itself. Tried flashing again, the same thing happens. Any other suggestions??

I flashed an international firmware on a Sprint S4, not knowing that it breaks root and custom recovery. I also lost my 4G. I can fix everything except the 4G. No idea how to begin, any idea?

Well you can begin by going to Sammobile and download the carrier's stock firmware. Flash it via odin. Stay on stock until you figure out how to fix 4G on custom roms.
Good luck, Im sure you'd be able fix it by flashing stock rom
Have you tried fishing the Sprint modem?

Sprint Modem? Can you go a bit more in detail please?
Indie offers an "EnableLTE.zip in the i9505 Omega Thread
This maybe fix the problem, OR AT WORST BRICK YOUR DEVICE
Honestly i have no idea if this works, so be careful.
Indie or another skilled person should know of this fix the LTE bug on your Sprint S4.

The modem is part of any full firmware and is usually different for each provider, region etc.
I believe the US lte frequencies are different to most of the other countries so if you don't have the correct modem your phone may be looking for the wrong frequency.
Try this link: http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy S4 (SPH-L720)/Modems
Flash the .tar file in odin in the phone section.
Edit: just remembered when the first ipad to have lte was released in Australia, Apple and resellers got into big trouble for marketing it as lte/4g. This was because although it was lte it didn't actually work with Australian lte frequencies. So as I mentioned above you will need a US modem. That's my best bet to get it going again.

Flashed it successfully, yet no 4g. Could it be that I need to flash a different firmware?

Maybe check that lte is selected in network settings and you have your apn set correctly.

I did, yet no dice. Would flashing a stock firmware replace the modem?

Hello guys,
I have encountered i problem after i updated my international note 3 officially.It said there is a new update for my device so i downloaded and updated it then it wouldnt recognize my pin.I took the sim card out then it said there is another OTA available.I downloaded and updated again in hope for a fix but it didnt recognize this time either.I blocked it and tried the PUK1 and PUK2 codes neither them both worked.Im using it now without my sim card.Its not rooted btw.
Thank you have a good day!
Only thing I can think off is boot to recovery and factory reset, see if it fixes it.
If not then you'd probably need to flash stock via ODIN.
However you need to note that reactivation lock must be off -- do you remember/know if it is off or on?

Its off sir under the Security settings.
You can re flash your stock rom via ODIN, have a read around and make sure you are 100% confident in doing so, then when your phone boots back up, you should be able to enter your puk code to unlock your sim.
I cannot stress enough the importance of reading as much as your brain can take in so that you are absolutely confident in what re flashing etc entails.
Good luck and keep the thread posted on your progress

What region of note do you have? If it's a Hong Kong one then you will run into issues.

Hey i have the Australian XSA which the unsubsidised international version practically buying it outright without carriers
Flash this via PDA in Odin. It should sort you out. If it bootloops again after you flash it, take your battery out for a minute or so, put it back in then boot into recovery, wipe cache and reboot. Should be 100% then.
Hey
Hey i did what you told me and now Root is not working even after flashing it on odin

I hope somebody can help me with this. My question concerns 2 S4s. One is rooted while the other is completely virgin stock. The rooted s4 won't even allow me to check for an update no matter how many times I try. The stock s4 will check but always says it's up to date. What can I do to fix this? I'm more concerned about the stock s4 since the update will break my root on the other. But I would be curious if there's an explanation as to why the rooted s4 is doing what it's doing.

The root won't let you check probably because of the modified system. For the other one, it's known that AT&T's OTA is kinda buggy and you pretty much need a full strength WiFi and cell network connection.

hello everyone,
yesterday I flashed the x-note rom on my note 3 and for some reason it got stuck in a boot loop so I flashed the official uk 4.4 rom and when it booted up I found out that my phone was absolutely no sound and as a result I cannot receive or make calls. I also tried flashing the volume boost mod and it didn't work.
help me please.
I'm desperate.

Are you using an Nordic/Scandinavian variant? - if so, flash back to stock. There is some issues with them particular variants and has been since 4.4.2. - Even if you aren't I'd go back to 100% stock to be 100% sure first to determine if it may be a hardware issue also.
