SIM unrecognized due to sudden corrupt IMEI - Verizon LG G3

I have had an unlocked VS985 for three years now overseas and its been flawless so far. It all started when suddenly one day the SIM failed to be recognized. I put the SIM in an another phone and it works fine. No other SIM card gets recognized on the device. These are a summary of things I've tried so far:
1) I initially thought flashing another ROM would fix it, and I tried like 3-4 ROMS available in XDA (thanks to all the devs!!). Nothing helped. The SIM continued to be unrecognized in all the ROMS. I then flashed back the stock ROM by the TOT method.
2) I then suspected it could be something with the phone radio and started investigating in that direction. I tried enabling all the bands through the shortcut app and that too did not fix it.
3) I found the hidden menus to attempt turning on/off the radio but found that I was unable to enter what's called as "Phone info" hidden menu (picture attached) that contains this radio on/off option. Although it didn't let me enter I noticed that the phone IMEI in that menu was missing the last digit. The IMEI in the Setttings -> about phone (or below the battery) shows an IMEI with the same digits but with one extra number at the end. I suspected that somehow this IMEI mismatch of the last digit IMEI was the reason the phone is blocked for all cellular connections.
4) I then tried fixing the IMEI with the Qualcomm QPST method but unfortunately unable to enable the DIAG USB ports. I tried that with adb commands with terminal emulator and all the commands are accepted without an error. But when I connect the phone with debugging the appropriate COM ports don't show up on the QPST configuration. I also tried that with the phone hidden menu (##7764726985) but the "Port check" option that must show up is just not there.
I am stuck now. I am not sure what exactly has happened and if my diagnosis on the IMEI is valid. A phone service center tells that the SIM slot is good and this is a software problem. Can someone please help me fix this? It could be a simple fix to access the DIAG USB port or a bigger fix to the whole problem. I just don't understand how the IMEI could have randomly changed when it was fine for all the 3 years thus far. It has been a harrowing 2 weeks trying to find a solution and I'm tired. Please HALPPPP!
EDIT: I was able to get into the debugging mode and was able re-write the correct IMEI. I restarted the phone and still its the same as in the first picture, missing the last digit. May be as a consequence, the phone is unable to recognize SIM or letting me access this menu

I received the SIM card unrecognizable alert, with my original G3. I took it into a VZW store and they told me it was a hardware failure. They replaced the phone on an insurance claim. Never had the issue again. I don't have any experience IMEI issue.

Yea, this is the exact thing thats happened to me (Indian version).
Fresh out of the box phone, worked fine for the last 3-4 days.
Now I'm out on a vacation, and the network selection on roaming was flaky, I was toggling the network selection manually/automatically a few times to get some network, and the next thing I know I no longer have a IMEI (shows unknown) , and the same for baseband ( shows unknown) .
Tried factory resetting , etc, not helping. Will get back home and have the phone repaired/replaced.

This airplane mode sounds dangerous. Unfortunately it may be a necessity when you are travelling etc. Hope there is a known fix or one comes out soon. Until then I will keep my /efs partition backup in 3-datacenter redundant storage place along with my laptop and ext.hdd.
i just recieved an sgs2 in uk and it has this exact problem out of the box.
grrr
if anyone wants to point me to a stock rom for it i'll try flashing it
erm, i dont think flashing will help here.
I reckon that missing IMEI means the /efs partition has been wiped out/corrupted, and that is something which cannot be restored by a simple flash.
finally, after almost 12 days, lots of running around, I finally got my S2 working again.
The service center had to send the phone to their head office since they hadnt received any service info on the new model till then.
They changed the PBA apparently , and finally reflashed it and gave it to me.
They claimed that the flashing was an online process and samsung india service servers were down for nearly 2-3 days, accounting for the additional delay.
Just like my I9000, but I dont think it is the same problem and same way to solve.
I rooted the devise and deleted the nv_date.bin and the nv_data.md5 in EFS file with Root Explorer, and renamed the .nv_data.bak into nv_data.bin, then restart, problem solved
I have exactly the same problem as you guys are talking about. Really weird. The /efs directory, where is it located? Is it located in the main "Root" or is it in a specific folder? I would like to try the thing with the rename trick?

[Q] [HELP] Can't register on GSM/3G networks

I'm here because I have a really big problem with my phone, I can't send any message and I can't call because my phone can't registered on GSM or 3G network. I can receive signal from networks but I can't register on it, when I select a network it's showing a message saying : "Can't register on network now, try again later". The strange things is that it just append suddenly, all was perfectly working about 2 years now. It append when I switch preferred network from 3G to 2G. At this point everything was fine, but after that, I reboot the phone and then I was unable to registered on network.
I've try many things, I was on running on CyanogenMod 11 Nightlies so I flash CyanogenMod 10.1 stable but it didn't change anything. I've also tried different radio, I was using XXKDH for 2 years so I tried to switch to XXKG2 but it didn't worked.
I've also tried to put the original Samsung Firmware, it didn't worked.
The problem is really coming from the phone because I tried to use my SIM card on another phone and it worked.
I really lost now and I don't know what to do. Is my antenna broke suddenly?
Please help me.
EDIT:
I find that the IMEI showed by *#06# was different from the one behind my battery. So, like few peoples I have the 0049XXXXX IMEI, I'm actually trying to fix my IMEI with this : http://forum.xda-developers.com/galaxy-s2/general/imei-baseband-guide-t1596842 and this http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 but for the moment nothing is working.
I can't find the .nv_data file so I guess I'm just ****'d but I will try something with .bak files and the efsbackup.tar.gz that was on my SD card for no reason. The most interesting thing I found on the efsbackup.tar.gz is this log file on attachment. Anyone now about what append?
I've also find that my imei folder was empty. Is this normal?

You might try installing this app it find/gives all the hidden info on your device http://forum.xda-developers.com/not.../app-one-click-hotspot-enabler-menus-t2816159 it will give you APN's MEID AND IMEI . All you have to do is download to your PC, it my download as a zip file. Just use 7zip and rename it to an apk, then copy and paste it to your internal sd card via your charging cable. Then click on apk and install. Enjoy !!!
BTW your MEID is on a label under the battery !!!

Hi Jim/XDA
I'm still not able to connect to the network. Regarding the IMEI on the back part i know its there however what im saying is that im not able to see my imei through command when i dial *#06#
i as well had this errors today when i woke up:
: LTE:ESM-x EMM-14(ive seen this error when this issue started but it dissapeared and it came back know)
data roaming: you have lost data connectivity because you left your home network with data roaming turned off.
On mobile networks i remember i use to be able to select many(GSM,CDMA,etc) now in network mode i only see 2 options LTE/CDMA,CDMA. Currently LTE/CDMA is selected and if you just look at the network mode option without actually opening it it shows CDMA/LTE/EVDO.
Also when i opened the SCRTN it shows on black screen.
I tried to do some minor changes on Galaxy tools like the SIM UICC UNLOCK all mps,sales,default code on XAS. Factory & keystring ON. MSL/SPC show 222222.
After i did SIM UICC UNLOCK and restarted phone know took away all errors but i see the signal bars faded out and with a little red x on top of it. I've read the manual but im still wondering if there might still be things to set on a particular way that are not specified on it Can you please help me set this up properly?

Is this a Sprint variant? If so, you shouldn't have factory reset the phone. It looked like the phone was previously flashed to MetroPCS and by resetting the phone, it removed all the carrier data.
You will have to reflash the phone to get it working again.

Is there a tutorial i could follow here ?
I greatly appreciate your help,

Hey guys, for those who need to edit an APN (Access Point Names), there is a little secret.
Go Settings, and scroll down the list. You will find a search box. Type there Access Piont Names and here it is.
The steps above are neccesary, since APN setting is hidden.

Null IMEI, Service Menu blank

Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?

Galaxy S6 Edge - Cannot Connect to Network (IMEI Issues)

Okay,where do I start.
So I bought this phone off a friend of a friend(I was going to sell it on for profit as it was a good deal).
I noticed when trying to update that it was telling me it was an unauthorised software, so i took it the device was rooted.
I then factory reset the device to see would it go back to factory settings, but just stayed on the custom firmware.
I then decided to flash stock firmware onto the device from Sammobile (device boots up with Three logo so I assumed it was with Three Ireland network so that's the firmware I chose.
After flashing the device it boot up with a dm verity error and would only go as far as the Three logo. After some research I found a discussion and followed the steps in this, flashing a file called CF-Auto-Root-zerolte-zeroltexx-smg925f. After doing this the dm verity error had gone and the phone booted up fine.
I left the phone like this, as I was going to sell it at a later date. Before I sold it I had one last test of the device and noticed it would not connect to a mobile network (I don't think this issue was there when I first got the phone as I am nearly sure I tested my sim card in it, but cant be sure). I just kept getting 'not registered on network' error.
After some more research I downloaded the Samsung info app and ran it. I then noticed a few strange things.
1). The serial number of the device was just showing up as a string of 0's.
2). The imei number that was listed did not match the imei on the back of the phone.
3). The carrier was showing as O2 UK, but Im not sure if this is an issue as O2 and Three are basically the same network here in Ireland (Three took over O2 here).
After doing an imei check, I found the imei listed on the back of the phone to be fine and was showing all the right details, serial number etc. But the imei that was listed as the imei of the phone, in settings and using *#06# was showing up as not existing.
I found this very strange and I'm sure this has something to do with why it can't connect to a network.
Any suggestion on getting this device back working properly as it is just a paperweight now as it is, and after spending money to buy it so I could sell it on I don't want to have wasted that money for nothing.
Any help is appreciated.
Thanks
Nothing? ?
