It looks like you have lost your EFS data and that means problems... Check if you can read your IMEI in Settins.
Look here for more information [Tutorial] Why my IMEI missing & NO network?

YES. You can also re checked your IMEI setting. I think this forum thread is also help you to how to do this IMEI setting change. You can see here thread http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 thanks

Try to get the original stock ROM to flash look here or get help from them about details, that's the normal process to recover from such problems. You should also remove any USIM passwords for your SIM card, best to seek help in such threads.

yes they can be resolved, read this as to why you get this problem and this as to how to solve it. unfortunately, I do not own a pantech vega phone or have acess to one, so you need to get help from the link i gave earlier.

issues
still the same issue here, i have given this mobile to a mobile expert, he tried to flash many things through touch custom recovery , like SK telecom original jelly bean flash file for korean s3 variant in my pantech vega a850L . but no progress. its been a while i got no success, i mean to say that more than one and half month past and i am stuck with it. i am posting the screen shots now. anYOne can atleast tell me that is it resolvable with riff box if its a hardware issue. You can see in last screen shot in which NO SIGNAL issues still exist.
imei
Guys also let me know, is there any particular way to flash anything like baseband and custom roms, i mean i did wipe cache delvik and similar stuff. but yeah i am totally new to all of these stuff .. and let me tell you one more thing that in my previous white Pantech vega a850L , when i used to press *#06# it shows me "IMEI" as"----proper imei numbers------" but now in this black pantech vega a850L when i press *#06# , it show something like this >> "MEID" as blank . nothing at all . You can see in this attached screenshot .
According to your problem and history it seemed Baseband CHip error,
but as a last resort you may try with some re-partition/re-format function from Custom Recovery.
Otherwise final try with JTAG Method from some professional
Good Luck!
Note:- Before JTAG batter to open your phone and check internal H/W for water/other damages
Haven't used a pantech, but doesn't it have its OWN stock ROM? why do you need to flash korean s3 firmware?
If stock fails, try to install an aosp rom, like CM - these work even with no imei, it also resolves not-registering problemos.

yeah but i am not very much of this JTAg , riffbox, i mean to say that is it related only to repair dead boot . wel in my case i am able to proceed further from booting and all that. but i am not sure what to do now, i tried to purchase this JTag today but voila so much expensive for a little piece of riffbox for a client like me. anyhow if riffbox is the only solution i will definetly go for it, and hey i am not kidding, please tell me this repartition format criteria? , i mean is this something to do custom recovery in the boot, last time it had a skin of some SK telecom custom firmware then in custom recovery i chose the option factory reset just like to install a new rom then i did the job i think , i mean after selecting that option my phone only got stuck with further proceed to nothing except boot and logo . then i have to install a stock rom from pdl download mentioned in the boot bios .but after installing stock jelly bean , still same unknown imei and unknown baseband.

This is at your own risk,
by now, I think you should have installed custom recovery and root?
The following is original kernel baseband for A830L , flashable zip,

Flash it from recovery.

the first impression that i took after reading your post here, i really misunderstood that how am i not gonna be so lucky. well i read many post in vietenamese forums regarding baseband files, but got no success, but the link which u provided i tried today and tried to flash first empty baseband and then the real one, it first show unknown baseband in the boot command screen when i flashed empty baseband zip file but when i went for real baseband zip file it show baseband versions stuff in boot command screen like this
IM-A850L Modem S1233211.Tp25
9615A-CEFWMAZM-3.0.114007
made by dvha79_ddt
---
but still not so sure why unknown baseband after reboot. anyhow i flashed Xperia Mod ROM and when i again check for *#06# . it shows blank now as imei "blank nothing " you can see attached pick.
The guy who almost did expert on this mobile for a month , he arranged for rifbox but he was not very much expert so he give up, and now i am still stuck, not knowing what kind of software or even hardware issue is this? but please read this baseband for me as if how to flash baseband files specially post#1 and post#14

I figure out your problem and recommend you installing a stock rom.BINX for Vega pantech, if nothing improved, let try to fix errors about baseband and IMEI by this tut: http://techhub24.org/backup-imei-fix-imei-errors-sky-vega-pantech/
after a year some1 replied, anyhow some other way i managed to get back imei and then sold it out in the market
please tell, how did you get your imei back?

Network/IMEI Lost and WiFi can't be turned on

Hi there.
I wanted to unlock my bootloader, root and flash a custom rom. So I first flashed the global fastboot rom 7.2.5, later flashed the s-twrp recovery and flashed the lineageOs 7.1. I realised that my sim cards weren't working so therefore switched to resurrection remix. Even then, I couldn't get the network even though wifi was working. So I flashed the global fastboot rom again. I still couldn't get the network. Then I realised that my IMEI number might've been erased while flashing even though I followed every step correctly. I dialed *#*#4636#*#* and found out that my IMEI numbers were now unknown. I got to know that my IMEI numbers were definitely wiped. I tried flashing recoveries, boot images, modem files, etc and now I can't even use WiFi. I tried using the WriteDualIMEI application but unfortunately it isn't finding the COM10/20/9/11 port. I have no clue what to do as of now. Can somebody help me with necessary links and details?
Thanks in advance.
Had this problem yesterday. You may refer to my thread on MIUI forum and see if it can help you. Assuming you have Kenzo variant like I do, refer to this and this first to recover IMEI number as well as EFS, then read the rest of my thread to get signal once you recover the IMEI.

Hey there! Thanks for the quick response! It really means a lot.
The EFS thing makes sense now since all my details such as MAC Address, Baseband, IMEI number, etc are all unavailable or unknown. I tried flashing the modem files but are still unknown. Any tips?

Did you try this guide to restore baseband/IMEI/MAC etc first? You may also use this QCN in case the XQCN in the guide didn't work. Follow carefully the guide. Then after you get everything, you may change the IMEI using tool found here . After that, follow my thread to flash everything possible to get all the connection back.

That QCN file was vital! Thank you so much! Now all there's left to do is fix the signal! I've successfully got my IMEI numbers back and the baseband!

[Q] Can I have some help with my SM-J110F?

Ok so recently I was successful to root my SM-J110F (Vodafone, AUS).
I had found a forum on xda for a custom ROM for SM-J110M.
(link) - https://forum.xda-developers.com/android/software/rom-cleanertlite-os-j1-ace-t3585567
I flashed the ROM using TWRP and it worked.
However sadly, the ROM isn't really that great. The IMEI shows it's "null / null"
so I cannot fix it. The forum hasn't been active so I cannot get a response from the person who made it.
I was wondering if there is any way to fix it and I know I have a custom ROM for SM-J110M but I just want to know if it can be fixed.
Also, since I installed the ROM, the phone says it is a SM-J110M. I was wondering if I could flash in a stock SM-J110M ROM from SamMobile. I tried flashing it using ODIN, but it didn't work.
I really need your help, because I want to stay in 5.1.1. otherwise I'm just going to have to go back to 4.4.4. which is really old.
Problem can be solved and to fix that problem you need manualy to write IMEI and Serial number .
To write IMEI , and S/N you can use Octoplus but Changing IMEI or S/N number which doesn't belong to you is Ilegal so do at your own.
Here is steps for you to follow.

[SOLVED][Q]I9300 No IMEI, corrupted EFS, no backup.

Hi! I have successfully revived a GS3 motherboard after it was dead because of SDS using this tool. As everything was wiped from it and replaced with zeroes I have lost original EFS (the former owner didn't root it so ... no backup of EFS). I flashed stock ROM via Odin (Baseband version is I9300BVUGNB2 and it's I9300XXUGPE1 firmware). I saw that others are having even a missing baseband version but mine is here. The IMEI is generic (0049...), when enabling Bluetooth I get a reboot, Samsung Internet and com.google.android.gapps are force closing and there's such a big delay between the time I'm pressing any button to wake the screen and the screen wake up.
1. I have no backup (obviously)
2. I have a working S3 with I9300XXLFB modem and I tried to restore its EFS to my other S3 motherboard with no luck
3. Don't tell me to flash stock ROM via Odin as it's obvious that a stock ROM won't restore a unique number which is missing from it's place. Or will it? Is it hardwritten somewhere in the memory?
4. No Samsung Service here in my city (and I'm not planning to search all over Romania for a service... I don't think it even exists )
What can I do to restore that backup? Also how can I change the IMEI back to original (I have it written on the paper) because I don't want to get the same IMEI on two devices
P. S. The other EFS is my property so I'm not breaking any rules or laws because I'm using it's base to repair another phone. Then I will change it to original. I hope I won't need to use the backup maybe it will work another way. How the services are repairing you broken EFS? ?
Any help would be greatly appreciated
The first thing to do is flash a stock firmware. Have you tried the recovery mode in kies?.

I have successfully written my IMEI and SN but now I'm getting 2 issues:
1. Not registered in the network
2. When turning on Bluetooth on 4.1 it won't turn on and on 4.3 it will freeze the device. Now I'm trying to fix the first one but the second one I couldn't fix. Any ideas? Should I rewrite BT MAC address too to fix it?

Why did you marked the thread as [SOLVED] & don't you answer @audit13's question & maybe help an other user with the same problem finding this thread?
As for your Bluetooth freezing problem I would say flash stock Samsung again after Formatting Data (not wipe see https://twrp.me/faq/datamedia.html for an explanation of the difference) & try an other modem.
I am running on S3 i9300 the I9300XXUGOK1 modem (2015-Nov-25) which I attached to this post as well as I9300UBUGNK1 (2014-Nov-6) & both are more recent than the I9300BVUGNB2 (2014-02-18) that you have on that device @ the present.

Thank you for your answer. I have already answered him in PM. I was busy with some exams and I didn't have time to write here something.
To write the IMEI you can use a tool from the web (payment recommended). Something like Chimera Tool or Z3X Pro
