I've researched all day on this, flashed stock rom and recovery again, and nothing. Phone is out of warranty obviously.
My IMEI is showing null/null and the baseband is unknown. I've flashed stock, rooted, tried restoring the efs folder, and nothing has worked. Phone worked just fine yesterday/this morning. Any suggestions?
In my efs folder, there is no NV_DATA.BIN file either.
Any help? TIA.
1) download just the modem from this thread http://forum.xda-developers.com/show....php?t=2252932
2) connect phone to pc
3) copy zip over (do not un zip)
4) reboot to recovery
5) install zip
try this it worked for me
What bootloader is on your phone? Flashing the a modem onto your phone that is not compatible with your bootloader can brick your phone. For example, flashing a 4.4.2 modem onto a 4.3 bootloader will hard brick your phone.

I'm on the 4.3 bootloader and 4.3 Stock ROM.
Do you have a mjb modem on your phone?
Yes, I do.
If the baseband is unknown, how do you know you have the mjb modem on your phone?
Maybe you need to re-flash the 4.3 mjb modem. If that doesn't resolve the issue, you could try injecting the imei using nvwriter.

You flashed the 4.3 stock ROM via Odin? Where did you get the file? It must have been a custom compilation because AT&T never released 4.3 as a full ROM, only as an OTA.

I used the mobile Odin method of flashing back and I also used triangle away before I did this if it's worth mentioning. So after struggling with getting back to stock all day I finally make it happen I put my SIM card back in and notice I am getting no cell phone reception. WiFi works but without WiFi I can't do anything data wise. I contacted t-mobile support and they found no issues with the SIM card
Anyone have ideas on what I can do to fix this?

Ok so more info, I used this unroot method and followed it very close:
http://www.androidrootz.com/2012/10/how-to-unroot-samsung-galaxy-s3-no.html
I'm guessing this is what is causing the problem, I flashed the modem from UVDMD5. Only the modem I could not get anything else flash on odin so it was only the modem. So if I had to guess its a problem of getting the right modem back on the phone.
(On a side note, will I ever be able to get my phone back to 100% stock/able to get official updates,ect? Is it even possible?)
Edit: As far as the baseband goes it says "unknown".
I have no idea what that version is. I Suspect its the dreaded UVUEMJC. You will need to flash UVUEMJC Modem for T999 from this thread.
EDIT- Yes its indeed possible to go back to complete stock in order to receive Stock updates. After your IMEI is restored, you can use KIES to go back to complete stock. Please realize, you can also get latest update from Sammobile.com and flash it via Odin

Dont know if you remember but I am the guy you helped in the other thread get unrooted. I was the one having trouble with it getting stuck at "system" when I was trying to get back to stock with the firmware from sammobile.com. Do you think it would be ok to try it again now that I'm on stock?
Don't recall the conversation. But there is a easier way to unroot by removing SuperSU after you get your IMEI back.

If you don't have custom Recovery, then use mobile Odin to flash the Modem.
Better yet, please flash UVUEMJC Firmware via Odin again.

In other words stuck in the same boat as the old thread.
Please post the complete log data from the second image of Root66.
You don't flash a modem that way. It can brick.
I had signal loss (from battery screen) at regular intervals.
To overcome, I wanted to go stock thru odin and then flash back. After odin, It boots up. but no IMEI
tried couple of times. What are my choices to restore phone to normal. I am hoping it is not brick, as phone boots up and can connect to wi-fi. Just no AT&T recognized as status page is all unknown entries (phone number/IMEI/baseband...)

How did you flash back to stock 4.3 when you have the 4.4 bootloader?
That would've bricked had it been successful.
Verify you are on NE4 by entering this in terminal emulator:
getprop ro.bootloader
If you are on NE4, go to my 4.4.2 modem thread in General section and flash the NE4 modem. That will probably solve your problem. If it doesn't, PM me and I'll help with the imei restore.

I updated to Cyanogenmod 11's latest nightly of 4/26/2015 and my phone started behaving badly.
I kept losing signal and having trouble making calls and in my attempts to resolve the issue by flashing back to a previous nightly it seems I lost my IMEI and with it connectivity.
I found a video on youtube that says to access the service menu to fix it but CyanogenMod doesn't do anything when I enter the codes in the dialer so I was attempting tro go back to stock but having trouble finding a good stock rom I can use and the 2 I"ve tried both fail in odin. Then I read something about needed a pit file but flashing that fails to.
So right now I went back stop recovery but still on Cyanogenmod but the phone doesn't do anything when it boots...just no connection.
Someone told me the pros in this forum could help so here I am, help me Cell Phone Gods!!!:crying:
Got this phone info app that says bootloader is I747UCUEMJB

Sounds like your modem may be messed up.
Load a terminal app and use the app to verify the bootloader on your phone.

Odin is failing with the stock ROM from sammobile because the phone has at least a 4.3 bootloader on your phone. Do not flash anything from sammobile because attempting to do so could brick your phone.
Since you're back on cwm with an mjb bootloader, try flashing the mjb modem via cwm.

I had even lost all my APNs in my attempts to fix. Now my APNs are back. Still showing unkown IMEI and phone isn't getting on the cell phone network.
So the baseband is now mjb?
Try flashing the latest release of CM10.2. It's possible you need to update the modem and bootloader together in order to support the newest release of CM11. I don't have an s3 so i can't confirm my theory.
You may have to try nvwriter to inject the imei as a last resort: http://forum.xda-developers.com/showthread.php?t=1804117

Hi everyone,
I know this problem is well known and solved many times already, but I'm not being able to solve it by myself. This is why I'm posting this thread as a last resort to try and get some help, just in case i missed something..
My phone is currently with unknown baseband and IMEI on stock 4.4.2 flashed via kies recovery. If I try to flash any 4.4.4 port ROM the phone locks up seconds after boot, it will only work with stock rom. I already tried a few modems i found on another threads but no success.
Can anyone help?
Thanks.

Isn't that a bit pointless? Maybe I'm missing the point, but if I already have flashed latest firmwares from both sammobile and kies, it kind of makes the point that modem and bootloader files from sammobile don't solve the problem, right?

Well truly doesnt seem pointless
I got my baseband resolved (Previously showed 'Unknown') by flashing pure stock rom (got from SamMobile) THROUGH ODIN so might be there is a point.
Try stock rom flashing from odin as according to me stock rom has everything in it radio(Baseband),boot(efs), system, etc etc
The unknown baseband and imei can be due to a modem and bootloader mismatch.
To confirm the bootloader and modem on the phone, install the Samsung Phone Info app from the play store to confirm the version.
I Flashed modem UVUEOH1 with twrp 2.8.7 now unknown baseband and no imei. Bootloader is T999LUVUBNF4 running cm 12.1.
Any advise on how to fix would be appreciated.
i have T999L not T999
