Has anyone fixed the Serial Number
My phone has been through a lot since it was bricked with the KitKat update. I got it fixed and it came back rooted. I've clean up a lot, learned a lot and I'm left with 2 issues. The serial number is incorrect and whenever it drops to EDGE it never comes back to 4G. I've found a XDA post that should let me fix the EDGE-4G issue but I still haven't found any fix for the incorrect serial number.
This forum has been invaluable in getting things working again. AT&T and Samsung were of no help.

Updated to 4.2.2, get no signal now

I restarted my phone, reinserted the Sim tried everything I'm still not getting signal, anyone have this problem?

How did you update? OTA, flash ROM, etc...Have you tried SIM in a different phone? Could be a bad radio? What does your baseband say in System> About phone?
It was the official OTA
I never updated because 4.2.2 killed LTE but then I did anyways
My baseband says unknown
Edit: the 4.3 update came, I tried updating but it said error half way through wtf!!!

See this a lot, updating killed the radio. You probably don't have an imei number either.
Try flashing an official factory image.

Don't waste time with doing anything else. Flashing the factory image will not get your imei number back and without it, you will never get a signal. When you call to RMA it, be sure to tell them you lost the imei number during the upgrade process. They should have plenty of lost imei cases in the system already.

Regardless it's safe to just flash the factory update, then see where you can go from there if all fails use that as your last resort

[NOOB] Is it possible to unroot 100 %.

I'm talking about getting unrroted status on the download mode also.
Yes. See this ->http://forum.xda-developers.com/showthread.php?t=2432476
this works, but make sure you have the firmware for the correct model number of your phone.
No, in order to unroot fully you must invent a time machine.

I was under the impression that once you root you blow a qfuse. With any fuse once blown there is no changing it since it is a piece of hardware that has changed. Not software.

Just fry the board before warranty

if i'm wrong, i would like to know. I did the procedure that I quoted above and the phone says unrooted on the download screen. d801.
My experience is that the phone displays no trace of having been rooted after performing the full unroot procedure. It says "unrooted" in the download menu.
Here are the steps specifically from Verizon users, with quite a few confirmations of phone returning to full "Unrooted" status.

There's triangle away for other phones but I haven't heard of it for ours, just brick your phone so it won't turn on before returning it

I had the same issue with the new modem not sticking. The only way it worked for me was to flash it 2 or 3 times in a row. Seems like this is not uncommon. The new modem did help fix my data drops so it's worth the trouble.

Unlocked AT&T Galaxy S4 not working properly

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??
