No GSM/Edge Connectivity . - AT&T LG G3

We had a few hours network outage due to security reasons. But my G3 didnt recover when the outage was over and is still stuck at "no Service" even after several reboots, clean flash of cloudy and restoration to stock using nandroid. It was working just fine a night before. I have tried restoring Stock from nandroid but still no luck. I have tried different SIM cards too but still no connectivity.
*#06# shows proper IMEI number.
Baseband was shown as Unknown, So I flashed one from xda threads for D850 V10D. Now my Baseband is known. But no luck.
Wifi works fine.
Bluetooth works fine.
Sim Toolkit works fine
SIM contacts are visible
AAT tests USIM1 Passes
I am back to Stock using TOT method.
I even had a bit of luck and caught some signals last night but they came and Whooosh gone again never to return.
It is to be known that I am in Pakistan and D850 is ATT US. Do I need to take care of any unlocking to make it work here that the shopkeeper may already have done before selling it to me ? Because it worked fine before.
Edit::
I checked for unlock code. my phone says "Phone is not personalized". So i guess I am not operator locked.
Previously I had posted this in "G3 troubleshooting" forum assuming it to be cloudy ROM related but I think its much more serious than that. So posting it here in D850 Forum.

Device locking is done in the operating system, not the physical device. I have yet to see a custom ROM or ASOP to be sim locked.
Now keep in mind, the phone won't show APN's for other networks when you insert your SIM card. What is going on here is the device is reading your sim card to identify the provider then set the proper APN as default. To test if it's unlocked, try a different SIM in the device and see what happens.
Edit: I'm assuming you are talking about a SIM lock. If it's a lock of some other sort, please provide more details with EXACTLY what is going on.

This is NOT a sim lock. What is going on is that your phone has lost it's APN settings or is using the wrong modem. a sim lock means that your phone will only work with 1 provider, installing the SIM from a different provider will give you an error message similar to this: ‘SIM not valid’, ‘SIM locked’ or ‘SIM not accepted’
Since the phone is working on other providers, i would believe that the phone has lost it's APN settings for VIP. I would look up the APN settings for VIP and manually put them into the phone and go from there.
A quick search found a thread with the APN settings:

Try to flash another Radio. I never had luck with KF1, and quite frankly it kept me from getting any service at all for like 2-3 reboots after.
Try KD1, or KB3 (those work for me).
Reboot a few times, and see if it works.

[Q] Reverse Flashed Galaxy S3 from Cricket back to Verizon

I made the mistake of not meeting at the Verizon store and bought a Galaxy S3 off Craigslist. It has a clean esn but it won't read the 4G sim card. I found out it was flashed to Cricket so I used Odin to flash it back to the original rom that came with the version of the phone which changed it to Baseband version: I535VRLEC but this still won't work it still has the same problem reading the Verizon 4G Sim.
I guess my question is... if there is a different rom I should flash it too? Or is it that once it has been flashed from Verizon to Cricket it can't flashed back to be used on Verizon again?
I would just get a new sim card from Verizon, that may resolve your issues. A few questions:
1) Does it still make calls and texts? The main issue is it doesn't connect to LTE? Maybe I'm not understanding your issue entirely.
2) Does the phone have your phone number and matching IMEI (labeled on the retail box) listed in Settings/About Phone?
You could Odin the stock image VRALF2, VRALEC was a pre-release image. Do not accept the OTA then dial *2767*3855# to reprovision the sim card. Maybe see if this resolves your issues.

Well when I brought the phone in the first time to get it activated I was switching from a Droid X so they gave me a new 4G Sim card. But yeah it won't make calls or texts and it won't connect to there 4G data network or pick up the sim.
So are you saying changing it from VRALEC to VRALF2 might fix it?

And at the store they told me it was picking up the Verizon network it just wasn't connecting I guess? so it wouldn't get on the internet or make calls or texts

What I was saying is that normally people Odin to VRALF2 or VRALG1 then reprovision their sim card. That code will work on VRALEC but I was just trying to put you on a common starting point since we here don't really use the VRALEC stock tar in Odin. Primarily what you'll find in the stickies are VRALF2 and newer images. VRALF2 was the "store bought" earliest software version of the Verizon GSIII from the summer. Its worth a try but consider the following first.
Since you said it doesn't call/text then I think you lost your IMEI. Could you check for me under Settings/About Phone? It should be 15 random numerical digits if I'm not mistaken. If its not 15 digits, it will be 0 or several 0's. Don't post the exact number if it is 15 digits, but tell me what you see.

No I didn't lose the IMEI it's still there, all 15 digits.
So is it possible to flash a Galaxy S3 from Verizon to Cricket. Then back to Verizon? Is it just a matter of changing to the right software?

Honestly I know nothing about flashing to another carrier. It's not something that I have a reason to research so I'm not knowledgeable in that area. My suggestion still is to run that reprovision code since you've already Odin flashed to VRALEC.
EDIT: To clarify, my suggestion is Odin VRALF2 then run the dialer code.
Just as a precaution, you should write down your IMEI, ERI, and maybe even your MIN and PRL version and store them somewhere on your computer. Since you don't actually have the retail box, this should be kept safe if we can't get this current situation straightened out. My reasoning is if you do somehow lose these before you're 100% fixed, having them written down may help you if you need to use one of the IMEI or ERI tools in the dev section.

Ahh, great! When you do just make sure to root, unlock your bootloader, make a nandroid backup in CWM or TWRP recovery, then use the "Comprehensive IMEI /EFS Backup" thread to properly backup your IMEI.
I encourage you to flash roms until you find something you like. I'll suggest that you stay with touchwiz roms then see whether sticking with Samsung's software in its various forms is good enough for you. If not, there's plenty of AOSP to go around!
So you just followed step 5 on the link above and it worked? (flashing with 4.0.4 ROM)
I'm going through a similar issue and been having a hell of a time getting mine to work. Mine was flashed to work on nTelos which is a CDMA provider in my area. I have flashed to just about everything possible (except 4.0.4) and haven't had any luck.
I went to the Verizon store and they tried to activate the phone but they couldn't but game me a sim to use and told me to call back if and when I could get it flashed back.
I tried at one point to take a working sim from another phone but it will not activate..... will not make calls, will not get data etc etc. when I dial 611 it still goes to ntelos.
Someone suggested putting Phone info on and setting the Phone to RUIM but I could not find that setting in Phone Info (even on the correct phone info, after time I found out the original phone info was pulled from the play store and I had to manually download it.
Anyway with the SIM I have and following section 5 as suggested mine does not give the option to accept or deny the OTA so I can try to enter the re-provision code. Should I get hold of the known working SIM to attempt this?
THANK YOU SO MUCH!!
The key to this however is to have a working SIM (the only one in our workplace was from an iPhone 5), I fashioned a nano SIM to mini SIM adapter and got the info on to the phone then my phone could finally be activated however the nano SIM I used got tied to my phone and couldn't be put back to the iPhone 5 it came from lmao... so I had to run to the Verizon store to get my co-workers phone re-activated.
But going down to the 4.0.4 and VRLEC modem then inserting the active sim, reprovision once it activates (it didnt give me the option to not allow it to do anything), then insert the mini sim, call Verizon they got it activated, I just now updated back to 4.1.1 (need to get 4.1.2) and everything is working wonderfully!!
All of this info is extremely refreshing to hear since I have the same problem with one exception. My s3 has a bad charger port. Sent it in for warranty repair and Samsung said it was moisture damaged and corroded and is not covered under warranty (lies). But that is beside the point and another subject.
My question is, can all of this stuff be done through the sd card and not through the USB? I know it is a long shot but any help would be greatly appreciated.
Thanks!
I know this thread is a little old but I just wanted to say thanks, the exact same thing happened to me (phone was previously flashed to cricket but i was unaware until AFTER purchasing and trying to activate)
ODIN Flashing the OMBINATION_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship.tar.zip package then reprovisioning with the *2767*3855# worked like a charm, I was sweating for a while as the deal was from craigslist
So far as i can tell to do this you NEED to use the VRAL as I tried a few other (newer) stock files and this was the only one that worked
THANKS AGAIN!

[Q] No connectivity at all

Hi guys
So I have the 23rd december version of Cataclysm installed, ElementalX kernel latest and I also flashed the 5.0.1 nexus 5 radio. Everything was working smooth for a day or 2 (no problems at all, I love Cataclysm). When I was on the train yesterday my connection (2g, 3g, 4g, everything) fell away as usual on Belgian trains in some areas, but it didn't come back... Now I'm stuck with a nexus that only has wifi... Does anyone know what to do? I have never seen this before so I'm clueless
I have tried installing other radio's. With the KitKat one, it didn't even find my SIM-card(no PIN login whatsoever)(this is also not a SIM related issue because I tried other phones). When I flashed the one from 5.0.1 back, it was the same issue all over again. I tried using * # * # 4 6 3 6 # * # * but it says my radio is off, gprs service too. network type unknown...When I try to turn the radio on via the button in the menu, nothing happens...
I did a full wipe in TWRP, installed cataclysm and elementalX again and again:nothing...

If the SIM is fine and it doesn't work on stock, then its likely a hardware issue, so I'd just go with the RMA.

Network not available at recently 4.4.2 flashed N8000

Hi guys. I'm posting here in a desperate attempt to solve my problem.
A year ago I purchased an used N8000 with Omega 4.1.2 ROM installed, and worked very good. But a couple of days ago, I flashed my tablet to get the 4.4.2 update, because I need some apps not compatible on old versions.
Everything is ok except for the fact that my sim card is not recognized anymore, if I select the operator manually, I get a "network not available" error.
I made a lot of research, with no results so far to fix the problem. The only thing I learned is that I think it has something to do with the baseband version. Currently I have the N8000XXUDND2 version, the IMEI is ok.
I live in Paraguay, the 3G band of my operator is on 850MHz.
If there's no solution, can I just downgrade to the omega rom by flashing as usual? Or the process is different?
Thanks in advance

I don't even know how can I check the original imei of my device, since I forgot to write it down. On phones they are usually printed behind the battery, but this doesn't have a detachable battery.
If your IMEI is wrong then restore your backed up EFS folder .

It's written at the bottom back of the tab & on the box seal as well. Or dial *#06#. I tired hard reset & stock rom still imei error
I checked and indeed there's the original imei written at the back of the tab, and it's not the same number as of dialing *#06#. Don't know how to restore though since I didn't back up any efs folder.
You can do a search on XDA there are a number of posts regarding users that failed to backup EFS and null IMEI .
I have the same error, after root, imei and baseband are gone.
don't have efs backup

No Internet Data in CM14 (no G,3G,4g)

Hi guys, I have been trying to get the MI 4c working with the data but still with troubles. I have restored to stock 2 times ( a long nightmare getting locked by the way) and still without getting the Data working. I can call and use internet with WIFI but not by itself.
Anyone can give a hand?
Trying with different bands in the menu of *#*#4636#*#* without a happy end.
THANKS A LOT
trying this guide about Restoring IMEI DIDN´T work!!!

Are you using 2 Sims? Have you tried manually adding the apn details?

I am using only 1 SIM, and YES I have tried to put APN manual.
Does the *#06# gives you an IMEI number (or 2...).
If not, what happen to loose it? You should start by explaining that.

It is giving me 2 IMEI NUMBERS but in Settings, About Phone and Status doesnt show my mobile number.
AFTER RESTORE TO LATEST MIUI I can use DATA 4g but I want to use Cyanogenmod instead, lets see.

That's not important.
So in the CM, there is just a problem with APN.
Post what are they maybe someone from your country could help....
After restore Stock rom MIUI 6.1.7, unblocked with fastboot oem unlock and flashing twrp and CM 14.1 I got 4g working I went to something about SIM CARD activate, and removing all APN and putting my APN manually. I did it before but didn't work .But after all it interrupts also WIFI after a few minutes I dont understand why.
