Phone Missing Baseband and IMEI - Verizon Samsung Galaxy S6

I need some help with my S6 - My Phone is stock, I have taken all the updates from Verzion - I have not tired to root this phone or load any ROMS to it.
I use the phone for works so it was loaded with all the airwatch stuff that does not like Root / Custom rom.
the Phone was working at lunch with no issues. I was leaving work and I was unable to to the internet and had no signal - so I rebooted the phone. after I rebooted it, it would be on for like a minute then reboot and keep doing it - So I did a factory reset on the phone. After the factory reset it would not register to Verizon. I checked about phone and every was unknown. Called verizon and the said that was bad- then told me since it was over a year old to go to best buy ( where i got it to see if they could help ). they were no help. I called Samsung to see if i could send it in for repair. They suspended all out of warranty repairs for some reason. so now i have a phone that i cant use as a phone.
I have loaded the phone with the latest firmware with ODIN and did not change anything.
Verizon gave me a new SIM card - that did not work.
the Samsung Desk at best buy could not do anything - they were trying to reflash the factory rom but they had a problem and told me the phone has been rooted.
the knox is not tripped - I have not tired to do anything to this phone.
is there anything that I can try to do to get this phone working again - or send it some where.
it is out of warranty - they will not fix it .
I don't have a backup of the EFS folder which i guess is what is wrong with it.

[Completed] Nexus 5 (hammerhead) IMEI set to 0

Greetings
its a long story but i'll try to keep it short, my mom's phone is the nexus 5, she moved to turkey, where phones bought from outside of turkey will stop working after two weeks or so (no gsm service) so she took the phone to a "repair" shop where they unlocked the phone, rooted it with some chinese custom rom, anyway the phone performance deteriorate significantly, so she gave it to me hoping i can fix it, so i installed nexus root toolkit and flashed stock android and unrooted and relocked the boot loader and set the tamper flag to zero, all is good by in the process im sure i messed up somehow and the IMEI now is set to zero, i cant receive signal on the phone (the signal statues keep switching between no service, searching, and no sim) even though it can recognize the network, i took the phone with me back to finland, and i asked LG if they can fix it, they told me they can try to reflash stock rom on it again, but no guarantee if its gonna be fixed or not, i thought in that case i might as well wait for marshmallow and see if it will fix it, i waited for the update for few days and today i decided to update it manually, i flashed the android 6.0 (Build Number : MRA58K) and still the IMEI is set to NULL, is there anyway i can get it fixed, i really appreciate your help and thank you for your time
Hi
Did you backup your EFS partition before using NRT? If not, chances are that you will have to return your device to the repair shop.

Good luck.

Help with network programming

I have a sprint gs5, i rooted it, flashed a modded verizon rom for verizons gs5. Boots up no problem. A couple processes stopping occationally. But otherwise seems to be working. I put my sim card in and it said the phone was activated and features updated. But its not my phone number. Its the phone number of the previous owner. I am trying to work on the programming but the programming codes you dial in the phone app do not seem to function. Just calls and says the accountcant be verified. Pretty sure its still sprints network talking as well. I did go try to add apn's but after hitting save they dont show on the list.
Sprint samsung gs5 with verizon rom and philz recovery flashed with ODIN
Rom currently installed: OptimalROM_15_odex-edition_bigbot96
Was not rooted or modified before i got the device.
Also the tutorials said thAt su would disable knox but that never popped up in my experience.
Boots i to recovery fine. Boots into system fine. Does not seem to accept programming codes. (Maybe they are differentforverizon?)
Safestrap apk installed but is blank when opened other thAn title bar.
Busybox and su both installed and work. Titanium bu installed and works.
I havent tried to contact verizon about anything yet.
Can anyone help me with the network programming?
I have qpst on my pc and the phone is detected. Reading about the spc and stuff like that but according to the pc the spc is all zeros already, i read that they are different on non vzw devices.
Maybe in over my head, just getting frustrated.
Will try to get some screenshots of the about phone details asap
If the phone is still using the previous owner's phone number, start by doing a factory reset in recovery. Then let us know what happens after it boots into Android.

help needed - S6 IMEI/BASEBAND UNKNOWN -

Hello dear ones, I'm lost and I need your help.
I've bought a used SM-g920f, knox x0. It worked flawlessly. Until the first evening when in the middle of a phone call the phone app crashed. After resetting the phone it was still unable to connect to network. I have noticed that baseband/IMEI were set to unknown and so it could not read my sim card.
First I have tried the obvious - upgrading from lollipop to marshmallow. It went easy but did not help. Neither did help resenting to factory settings.
I have rooted and installed twrp recovery adb and stuff.
After almost two days playing with it, I seem to be out of options.
What I tried:
Flashing Different roms - stock and non-stock. (G920FXXS3DPB2_G920FXEU3DPB1_G920FXXS3DPB3_HOME, G920FXXS3DPB2_G920FOXX3DPB2_G920FXXS3DPB3_HOME, Pure-Stock.ExtraLiteROM_XXU3DPCA.DEODEX-v5.5.by.ambasadi, XtreStoLite-ROM-3.0-Final-DPCA) - I do not know the country of origin of this device. (the back is from testing unit), is there some way to know correct original stock ROM ?
Flashing Different modems - (G920FXXS3DPB1_Modem_TWRP, G920FXXU3DPB6_Modem_TWRP, G920FXXU3ZPA1_Modem_TWRP)
Checked sim card in another phone/different card in this phone - if sim card would be invalid, would I still get missing baseband?
Xposed Imei Changer - it did change IMEI. But that's it. Baseband still missing.
*#0011# and other *# stuff..
And I have wiped /efs (it did generate new nv_data. Guess now even broken IMEI would make ma happy)​
Any ideas ?
How can I know what can be wrong? /efs partition? wrong firmware combination? hardware issue?
In Samsung Phone Info I get empty on Modem Board, Hardware Revision,Samsung Serial Number,Baseband Version.
Than you for any help or idea!
tried smart Switch emergency reinitialization?
Just to be sure, knox is triped now?

*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

Note 9 (SM-N960F Exynos) incorrect IMEI

Disclaimer: So its not a stolen phone, prior owner was just being nasty. I bought the phone from a 2nd hand shop (Cash Crusaders, Kathu, South Africa), where they told me that a lady sold the phone to them, came back after 3 months and wanted to buy it back for the same price (they guarantee buybacks for 1 month), they refused to sell it back to her at selling price, so she went and had the phone blocked. They went through the process of unbricking it through the ISPs, but in the meantime also got repair shops to try and fix it... They changed the IMEI number... So I bought the phone, fully functional, did a factory reset, saw that it had OEM unlocked and figured it was the cause for the biometrics not working, turned that on and thats where my mission started. OEM locked, custom firmware detected... Used Odin to flash on stock firmware (from Frija), got the phone functional, but emergency calls only and no cellular. I have tried rooting and using console, I have tried changing it in the EFS file, I have tried changing it via ADB Fastboot, via dialer (does nothing even with Google Dialer Framework V5)) no dice, it keeps the incorrect IMEI. I have looked up the IMEI on IMEI.info and its clean, so I take it they managed to get it unblacklisted, which is why I want to get the original IMEI back.
What I would like help with is does anyone know how exactly I can change the IMEI number on my phone (Rooted with Magisk and TWRP, but eXposed framework is finnicky and doesnt register properly, even through I installed the RIRU (V23) and RIRU EdXposed (Canary, both Sandhook and YAHFA on seperate occasions) packages via Magisk (V21.1 and V8.0.3 for manager) as per instructions.
P.S. I am a student on a tight budget, so I would prefer to do it on the cheap/free and I live in Namibia, so sending it to Samsung isnt quite an option.
Also please let me know if there is any info, logs, etc. I can attach that might help.

I have my receipt and they have theirs. So by all means verify the IMEI yourself 356630093456642.
There Are some leaks at "g-works..." To Get into a phone that is reported as lost.

Thing is phone got cleared. Original IMEI is clean, which is why I wanna reset it back to it, only problem is they seem to have used a flash-kit to change it in the recovery partitions too (bricked the damn thing when I recovered it (accidentally turned OEM lock on...), I've tried everything down to loading the engineering combination file (interesting though, its android 8.1, which shouldn't actually be possible to do from Android 10) on it and trying through there, no dice. Also asked local repair shops if any of them have a flash kit, none have 1... So I'm stuck at this point, cant even do the normal 'pay a repair shop to fix it for you' method.
