So here is the deal. I had a region locked 935F that I was able to use region lock away to activate. After this I flashed Supermanrom and superstock kernel, but I created a full TWRP backup before this. I also created a TWRP EFS backup before trying the region unlock. I was able to connect to Tmobile after the region unlock, but not after flashing SupermanROM and now I can't connect at all.
I have tried flashing stock via Odin
I rerooted the phone and attempted a EFS backup/recovery via the EFS backup app and it shows no EFS/IMEI info error
I have tried restoring via TWRP
I have tried to check the Partition via ADB, but I do not know enough to not mess it up
The IMEI shows correctly on the device, but it will not register to my network at all (no voice nor data)
Can anyone help me out so that I can get my 935F working again?
Tried running the Region unlocker again?
If IMEI is showing the EFS partition should be good
Was it a second hand phone? Certain it hasn't been reported stolen and IMEI blocked?

After reflashing I was able to run the region unlock again but it still doesn't pull anything. The phone was working for a short time so the IMEI is not blocked

It doesn't say its blocked. It says unknown. Swappa IMEI check says that the device does not appear to be blacklisted

Hello
I unlocked my device via USB with srsunlock.nl
I rooted my phone prior to this as instructed in email sent to me.
It seems to have successfully unlocked my phone, however I am now unable to connect to any network carrier whatsoever due to my phone now displaying an IMEI of 35000006 which I am guessing is a null/fake IMEI? I have no backup efs files, no backup nv.data bin files. I have tried to root the phone again and reinstall a stock rom via odin but has made no difference, still having the same issue. Knox warranty is also void now (says so when putting phone in to download mode).
Model is Galaxy s6 G920F. The carrier it was originally locked to is EE (UK).
Is there ANY way to fix this problem or am I completely screwed? Please help!

Does the software on the unlock will not automatically backup EFS or NV DATA?
The world has this kind of ridiculous unlock software exists?

Hey I really appreciate any help that you can provide. I will tell the long story. My phone got corrupted while flashing different custom ROMs. Oxygen was the culprit. It completely damaged all the partition of my phone. So I repaired via 9008 modem loader using COLOR OS flash tool. then I found there is no baseband and IMEI. EFS partition damaged and I didnt have a backup. Damn it!!!!! Tons of research and googling I found how to use QPST tool by Qualcomm. I retrieved QCN file from friends ONEPLUS ONE (16gigs) and flashed it to my phone (64gigs) and edited the IMEI to my one. Rebooted the phone. tada. I got wifi bluetooth everything running. Phone signal just connects and drops every sec. It wont stay connected. but it is detected. then I thought it might modem issue. I tried every single modem out there but no luck. Finally flashed CM11s 44S Modem. Kaboom. Got the network running. but sadly it will only connect to 3g. I cant connect to 4g. No Other modem works.
1. Only get 3g service via 44s modem on any vanilla rom.
2. No other modem works.
3. Proximity sensor acts really weird. If a call comes Then I have to restart my phone to get the screen lit back. Fixed by flashing proximity fix
4. Baseband is always unknown with 44s Modem but has 3g network connectivity.
5. Other modem shows baseband but no connection even though it is detected.
Please help me guys.. What am I missing. any help appreciated.

1- Check If you have IMEI and IMEI sv and it's the IMEI that shows on box.
2- if no. 1 is true then check another sim card another operator ( to be sure that carrier is not blocking your IMEI for some reason).
3- if other operator's sim worked contact your carrier to check problem with them.

Hey thanks for the reply. I do have my IMEI from the box. I flashed QCN file using QPST tool and applied my IMEI but the thing is I only get 3g. 4G is not detected. Im not sure if something has to do with baseband files. But my friend is from my place and he gets 4g just not me. If I use any other modem other than 44s Modem the network will be detected but won't connect so i cant make or receive calls or anything related to service provide.. Do you know what to do ?

Okay let's make some tweaks :
1- backup modemst1 and modemst2 using dd (I don't trust qcn backup ) and copy them to your computer I also prefer to backup persist and fsg
2- download NEVER_SETTLE from https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (you will find commands to backup mdemst1 and modemst2)
3- flash only persist using fastboot and reboot to system and check everything again.
other partitions locations :
/dev/block/mmcblk0p18 (fsg)
/dev/block/mmcblk0p15 (persist)

IDK what i did my opo was dead for around 3 months, the screen was responsive but totally black. then managed to recover from it then bricked it.
just figured it out. I am on my own build of XOSP[maybe it had problem idk] but had to flash my efs[64gig] backups and got my original imei back [earlier i had restored to a different imei qcn file may be it belonged to a 16gig opo] and also got 4g signal but still no baseband.
Then flashed COS13.1.2 and got baseband back, now the proximity is also working as it should and also got LTE working and instant signal on restarting the device. Now again back on XOSP everything works. If you need i can pm the efs files.

FYI your IMEI will be lost if you do so.
So I suggest to backup your partitions first in case of everything goes wrong.
Any way I have qualcomm stock efs partitions with 0 IMEI in case if you need them

IMEI is encrypted so if you do so, you will see it in settings but network carrier will receive it 0. This means that you won't get 4g also only 3g. So I personally prefer that you flash efs of [MENTION=bablu084;70545585]bablu084[/MENTION] this gonna work except you're two in the same country.

I'm the dumbest person on Earth. I own now a G930F brick that lose IMEI after updating to Nougat and I did the steps to recover my EFS from a Post here and now I have a Kernel Panic that says Power Reset or Unknown Upload Mode. I tried several times to flash on Odin my latest stock ROM but nothing happens. My laptop recognize the phone so as Odin but I don't know if I have to use other software to recover my phone. I can't get into bootloader mode, it just says some codes and the android logo saying power reset or unknown mode. When i press vol down and power to shut it off it gets stucked on samsung logo and some codes on green and pink upside to the left. I just can't turn off the phone so now its plugged to the wall.
I hope someone can help me... I'm really sad about it, sounds funny but I really I am.

Try a different network SIM, maybe it's SIM locked to a specific carrier
And check if the IMEI is blocked, that happens a lot with 2nd hand phones, either reported stolen or the original owner got them on contract, sold the phone then stopped paying the contract and the carrier blocked the IMEI

Yeah that's what happened. I went to a service center and they told me that my phone has the imei blocked so they flashed a stock mm rom and then they plugged some kind of special cable to change the imei again. They told me that i can't update anything so now phone Is working on mm and i just have a last question about it. Can i update to nougat on odin without flashing the modem or something to not lose the imei again or Is just impossible to update. Phone Is rooted and twrp installed, that's how they gave it to me.

IMEI is on the EFS partition, you can backup your EFS partition using TWRP and other tools, so I guess you could restore it if you killed it again
Don't see why you couldn't flash an updated custom ROM via TWRP, but if you're flashing with ODIN you'll lose TWRP
Unless there is something else they did that requires that exact firmware
But we are reaching a grey area of what is allowed to be discussed on XDA as changing IMEIs is illegal in most countries and not to be discussed here

I bought an S7 recently with an IMEI blocked by T-Mobile.
Update: I have, successfully, flashed to G930U. This was done through Odin following this thread: https://forum.xda-developers.com/tm...g930u-firmware-to-t-mobile-s7-t3533918/page1
Good news is that when I insert a different SIM card I now get access to a prompt asking for an unlock code. Maybe I can unlock it for Verizon, Sprint, etc?
Bad news is that I currently am on MintSIM which use T-Mobile networks. So it cannot be activated.
More information: I did ring up multiple times to T-Mobile and managed to get a difinitive answer that "Yes" it is still being financed, and therefore only the account holder can activate it.
I think my best option is to sell it making the bad IMEI number clear. Or to purchase a broken S7 in hopes of replacing the IMEI number physically.
Previously:
I want to switch firmware so I can unlock the IMEI without going through T-Mobile. Would it be possible to use Odin to flash Sprint firmware or Deoxed firmware?
I rooted the S7 and tried to install the Deoxed firmware through FlashFire but the S7 interrupted and restored it to default firmware. Which app files do I need to disable to stop this happening?

I have changed the IMEI number to an old phone of mine. Which is legal AFAIK, but it still isn't letting the phone be unlocked by T-Mobile.

Check my signature
EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

What happens if you restore from the OEM function?
Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck
Sent from my [device_name] using XDA-Developers Legacy app
If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Update on the post, I sent it into Samsung. I should hear word soon if they can fix it and how much if anything.
Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.
the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.
Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.
What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.
Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,
