Strange efs/imei problem, wont flash to stock

so I have a SR I just put a new (used, off ebay but new to me) motherboard in, and it works fine except for no imei/baseband, so obviously no data/voice/etc.
the efs folder seems to be fine...imei folder is in there, keystr file is there...I don't understand what the problem is.
the worst part is, only certain roms will flash...I cannot flash to stock, I've tried with odin and from recovery, a couple different stock versions of GB, ICS, and still no luck. It actually flashes, then does the "android is upgrading" screen, but then bootloops on the optimizing apps part. I've tried to flash to stock probably 20 times now, wiped everything, fixed permissions, etc...without fail it bootloops every time.
the only roms Ive gotten to flash are slim and jedi...no stock rom will flash, nor avatar and a couple others I've tried. but slim and jedi flash and boot right up...just have blank imei/baseband.
I've scoured threads for days trying to figure out what to do here...nobody seems to have my exact problem, and everything I've found about restoring efs/imei/baseband has involved flashing to stock...which I can't do.
anyone have any ideas?

Have you tried flashing different radios (baseband)?

Take a look at this thread, it may help. http://forum.xda-developers.com/showthread.php?p=25172599#post25172599

thanks for the replies...
I've flashed UCM1 and UCLL3 radios, they flash fine but no change...still can't flash to stock and no imei/baseband/service.
That fix thread was one of the first I found, but as I still have my keystr file in the efs folder, I didn't think it would apply to me...I suppose I could make an external backup of my efs, delete it and try one of those methods from scratch.

read through the restore to stock sticky http://forum.xda-developers.com/showthread.php?t=1652398 and go through the trouble shooting sections, if that doesn't help u could have bad hw

Hey, Im facing the exact same problem! just that my imei turned to 0 and basband to unknown after i upgraded to cynogenmod 10.1-rc.2.
It was working fine till suddenly one day i lost network. I tried everything like you did. So far ive had no luck fixing my efs!
What you can do is download QTPS and in it there is a RF NV Item manager to rewrite your efs. For that you need to put you phone into DIAG mode unfortuantely i cant get to that on 10.1nightly cynogenmod that im using.
I m stuck. I know for sure flashing roms or radios wont help at all. the same boot loop problem happens when I flash using odin, it use to work perfectly fine earlier.
Some how the nv_data.bin and such files are missing from my efs>imei folder that contain the imei data.
If you find something please lemme know too [email protected]

will do.
also, you may know this already, but just in case, be aware the skyrocket doesn't use nv_data.bin...I thought it did too when I first started searching around about this, and when i couldnt find it I was pretty freaked out...but then i found out the skyrocket actually uses 3 encrypted partitions rather than a nv_data file. so if you have at least some files in your efs/imei folder you may be in a better spot than it seems. of course if its totally empty, you'll likely have a lot more work to do.
I'll update if I have any luck.

Yes I have two files in my imei folder i,e keystr and mps_code.dat!
I tired changing them from root explorer! pasted someones else's efs folder! but still I cant fix my imei is stays 0.
i donno how to get to diag mode with this rom, otherwise i could have tried my luck with QPTS.

Incase you have broken your imei without backing it up, there is another way. And yes it is legal.
Here's the tutorial http://goo.gl/wtW29 and here's the needed tools (software & hardware) http://goo.gl/54mtk.

I actually have octopus box as well as the z3x samsung tool installed, however, they're both server activation based...the software is useless without an $89 (octopus) to $120( (z3x) activation.
I'd rather not spend that kind of money for something I'll likely only need once, so I'm gonna do as much as I can in the way of free solutions, and if I have no luck there I'll probably just send it to mobiletechvideos for their $40 efs/imei repair. I'm guessing they use one or more of these repair box programs themselves anyway, and will do the same job for only $40.
thanks for the suggestion anyway though..

There's this polish guy who probably also has all the same boxes and he takes €10 for imei repair by remote desktop.
http://forum.samdroid.net/f70/repair-imei-s2-5729/
And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

Isn't there any way to fix my imei on my own ?
Mt efs folder also looks good now with all the files it should have but still the imei remains unaffected.
Also i'd like to know that the qualcom nv tool showed my esn as dead and mied as 000....000 does the dead thing mean it isnt repairable ?
I tried using QPTS but this is where I get stuck.. (img attatched)

Obviously there is since some random polack can do it for you on his PC, the problem is the lack of knowledge.
Those who know won't tell you how, because they want € for it :crying:

People want money for it because it's mostly used for making stolen phones work again.
That means real life risks like fines, jail etc.
Of course there are lots of examples when people experiment with this or that and delete their imei accidentally, or want to change the imei for some other reason. But these are more rare.

An update...
I managed to finally get flashed to stock...still null/null imei & baseband unknown. Efs folder is still there with files, keystr file is on...not sure what else I can do myself at this point so, I guess its time for the Polish dude or mobiletechvideos.

unfortunately not for me. I finally got the polish dude to try restoring the imei remotely...he used like 3 or 4 different programs, nothing worked.
so, i just got a broken SR with a cracked lcd off ebay for $50 and used the motherboard from it.

Ohkies.
Did you ask the polish guy about the reason why he was not able to fix your mobile. Coz, I'm just having similar problem like yours. I tried working with all the local samsung service centre guys, nothing worked. One guy said that my mobile IMEI is locked in some database, so it is not picking or detecting my SIM, hence locked. I know that my mobile is unlocked and is valid, I ignored his comments.
I assume you changed your MotherBoard of the mobile with the new cracked SR's, so that it could take new IMEI instilled in new board. Is it so?
Also, please suggest me about any alternatives on how to fix this problem.:crying:

[Q] i9305 pit file missing & i9100 with imie and no sim issues

Hi Everyone,
I'm new here and fairly new to android too but have a rough understanding as I would see it compared to most of you.
I have 2 phones here that I have acquired cheaply due to issues (not questionable backgrounds) and done extensive research here and across the net on each of their problems but come to no real conclusions with either one.
Phone 1: Galaxy S2 16gb GT-I9100
Phone operates perfectly... as a mini wifi tablet. Doesn't seem to recognize any kind of SIM I put into it, just gets no signal at all. Baseband, IMEI, IMEI SV, IP Address, etc are all unknown. Signal says 0dBm 99 asu. As far as I can tell from what I have read this is an EFS file problem.
I have tried swapping EFS file with one from another S2 I have, start up with a jig, new rom flashing x2, and have recently got a program call EFS Professional 2.0.70 but have no idea how to use it. I believe you can write an efs file but needs to be in Linux? I have also been told this is most likely a motherboard problem. What is the way to fix this myself if possible or possibly with someones assistance if you feel generous?
Phone 2: Galaxy S3 4G 16gb GT-I9305
One day the phone restarted itself and without showing any boot screen just showed a white screen with coloured dots shaded through it. This screen also happens when attempting recovery mode. I can access download mode. Phone appears in Odin.
I have tried try to flash official samsung release 4.1.2 BLL3 rom I get the error message that: 'There is no PIT partition'.
When flashing just cwm recovery or a kernal with no rom I get the same message. When trying to flash m3xx_i9305.pit I get: 'Get pit for mapping' and it just hangs on that. is this something that would take hours to do or is it just frozen? I also have PIT magic but not too sure how to mess around with that... Should I just get the text readout of the pit file from another i9305 and compare the 2 to make sure it's right? I have been told this will need a JTAG repair but then others have had success. The only thing I haven't been able to try yet is flashing a pit file with the rom as a 3 part file.
A repairer has told me that the S2 EFS problem is a maybe fix and could be the motherboard so not to get my hopes up and has also told me the the PIT problem is a fried flash chip and isn't really fixable.
Another offers JTAG for $60 and a $45 refund if it doesn't work and also an EFS repair service but is on holidays for another month.
Any help or advice would be greatly appreciated but I have researched this to the best of my ability so please only comment if you really know what you are talking about and have encountered (and fixed) either of these problems.
Thanks,
Regards Evcat

Bricked S6 please help

Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav

it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.

Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?

Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys

OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav

1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.

OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks
Mav

Been searching for ages can anyone please point me in the right direction for a fast download of stock o2 5.1 rom? I believe I may need this one G920F_O2U_G920FXXU2BOGC_G920FTEF2BOG1.zip at the moment rapid gator is going to take 10 hours lol.
Thanks
BTW is anyone out there on the s6 forums hardly getting any help really want to try and sort this thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition

Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like

Here are screen prints but I think I'm speaking to myself lol

Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.
---------- Post added at 08:46 AM ---------- Previous post was at 08:37 AM ----------
Uhm can you send sms or make calls? It seems you have a valid Imei

Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys

Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.

Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.

[GUIDE] how to fix EFS Damaged on samsung devices [EASY!]

Edited in 2022 to make it look a bit better!
*WARNING* *TAKE A NANDROID BACKUP OF EFS AND BASEBAND BEFORE STARTING*
Hello people, first I want to say that this is my first guide so it doesn't really look professional but I am doing my best to be clear as possible.
In this guide I will be showing you how to repair your IMEI for free/without Z3X box
So lets get into it.
Its better to start fresh in stock rom
So flash the stock rom first
Now we are really starting,
Step 1) flash TWRP and flash Magisk (if you weren't rooted yet)
Step 2) now search for a custom rom for your phone download it before doing something or just download on pc and move it later
Step 3) now go to mount and select efs or else your efs will be empty at the next step
Step 4) now go to file manager and goto /EFS
Just delete everything in it OR YOU CAN LEAVE Privo data and factory app, you have a backup anyways. *WARNING: DO NOT DELETE THE EFS PARTITION IT SELF, IT WILL MAKE YOUR PHONE NOT BOOTING ANYMORE ONLY DELETE THE FILES INSIDE OF IT SO DELETE ALL FILES*
Step 5) now flash the custom rom for s7 edge i would recommend kingrom, do full wipe at the aroma. You may try to skip this step. There have been comments saying that this guide also works without this step.
Step 6) now reboot your phone, first reboot may take 5-10/15 minutes please be patient and make sure you put your phone in the charger if your battery is low now when your phone is in the welcome screen look or your signal is returned if not just setup your phone sometimes it may take a while for the signal to appear. If your signal is returned then go to phone app and dial *#06# and look or the IMEI matches the IMEI of the box of your phone (make sure you have the original box if you don't have this then open the back of your phone (if you can), there is a sticker label with your s/n and IMEI. If you cannot open the back of your phone, then you will have to trust that the IMEI is right. If everything is functional then you're done with this guide. The next steps are more ''checking'' if everything is alright.
Step 7) If your s/n is ok skip to step 8 if its not right then download a root explorer and go to /efs/factoryapp and edit the serial no file with a text editor and enter your s/n there now save it and IMEI and s/n should be alright
Step 8) Now, for IF the IMEI is correct and everything is fully functional, then delete the earlier made backup of EFS and baseband and make a new one with the working partition, then save it somewhere safe on an external drive, the cloud or on an USB, or just a pc that you will never reset or wipe its data.
Congratulations on getting past step 8. I hope this guide has helped you and that it worked for you. If not then I'm sorry for not being able to assist you. This guide is just me sharing what I did to solve this issue. Good luck on solving your problem if this guide did not work.
If the IMEI is not correct or this guide doesn't work then I can't help you any further except for if you have any questions, however I found a guide for the Samsung galaxy s7/Edge (if you have s8 then click same link because the thread has a link to s8) by Cubz (thanks to Cubz for his guide)
Link: https://www.google.com/amp/s/forum....ow-to-fix-check-drk-imei-issues-t3379516/amp/
S7/E/8 only and some other models as long its an s7 (edge) or s8/+
******* Some tips when you follow the guide*******
1) When you flash combination firmware and it gives you errors then dial *#1234# and look at the cp it should have UX in it (X could be 1,2 or 3 download the correct firmware with the correct bootloader version. You can upgrade from u1 to u2 and u2 to u3 but not downgrade from 3 to 2 or 2 to 1
2) If it didn't work then flash back to stock and fully delete everything in efs folder then retry (this is actually just guide B) its better to follow the guide above
3) If you got bootloader exception error then keep tapping the home button fast until it reboots then just manually reboot and enter download mode
The first method was tested and worked on SAMSUNG GALAXY S7 EDGE SM-935F it may work on other Samsung devices and maybe other android devices but I cannot guarantee that it works on your device
** I take no responsibility for any damaged device, make sure you take a back up so you can go back to the state before you started following this guide!**
If the device gets bricked then always flash back to stock, if you cant enter download mode then just wait until your battery drains and then when you put it in the charger it may start up automatically so enter download mode fast or if you got bootloader exception error then keep tapping the home button fast until it reboots then just manually reboot and enter download mode

Happy flashing and please confirm in the comments below if it worked for your device or not

Guys please comment or it works on your device or not!

It works for me. But I have to manually change CSC on my phone after original rom flash to fix Network. TGP rom have that option.

I followed your guide and my model name changed from G930F to G930FD and my IMEI is just bunch of zeroes wtv

SOLVED AT LAST - MISSING IMEI and EFS DAMAGED SOLUTION
Hi Guys,
First off, please take GOOD note - I am NOT a techy, just an old boring flashaholic who works in an office and likes pyjamas more than partying. This is my account of me fecking up my phone and finally reaching a solution after three days and most of two nights to a missing IMEI, messed up EFS and non-working phone - hoping that it might help anyone as desperate as I was. You do what you do with your phone and that's your business and I'm not responsible if you mess it up, but my hope is that you have have a brain (that's all I have) and you get some helpful piece of info here as I did from a whole ton of posts I read that finally led me to this.
Next - I am not sure what landed me in this mess. I've seen Superman Rom mentioned a couple of times..I didn't use that but I did use Batman Rom which is by the same Dev. It was great to use, too, so I'm not faulting the Dev by any means. What did happen, though, is that when I flashed other ROMS, maybe 3 or 4 of them following, the Batman splash screen was always there before the new ROM's boot sequence, so there were clearly some residual things of it in there ...so perhaps the same coding is in there and could have had something to do with it, I don't know. The breaking point came when I flashed Sac23 Rom hoping to get Pie on my phone. It was cool but I decided to revert to Resurrection Remix - always my favourite overall - and all of a sudden I get errors.
What should have been a routine "Restore" of my backed up RR ROM via TWRP gave "Error mounting EFS". Reboot, wipe, retry. No joy, same again. A couple of tries to restore the EFS from the backup in TWRP didn't work either.
Next go to is flash "original firmware" (more on this wording later). I had that on my PC (not a phone backup, just the firmware so it's clean copy with no data).
Get Odin out, download mode, correct files in correct boxes, all that standard stuff you can find guides on most places - no joy.
Error showing was "Fail at pm.bin" or something like that. Install aborted.
Try again. This time "Fail at cm.bin" Install aborted. Reboot from recovery also fails. Oh sh1t.
Several more attempts made. I have five different Odin vers. I have seven different firmware vers. I have two USB ports and about 8 Samsung cables. Not a single combination I tried worked.
The XDA heroes will know what to do, I thought. I read and read. And read. And CubZ (who is a hero even if he IS from Lancashire ), says MAKE SURE YOUR PHONE IS RUNNING ORIGINAL SOFTWARE. Well...I kinda did that mostly already...but maybe I need to go RIGHT back to the rubbishy 6.0.1 version that came actually ON my phone when I got it....almost 2 years ago? Who remembers that stuff?? I'm about 18 ROMS down the line now. I was desperate. I'm telling you...I even got out my bank statements to trace when my first payment to my current provider was...I read about firmware numbers and country codes, and I chose one from Sammobile with a build date, country code, unbranded code (which my phone always was) and correct phone model (of course!) as I needed. And it WAS .."the ORIGINAL" firmware.
This time I swear Odin failed me a second BEFORE I pressed the start button! No joy.
Have a flask of coffee and a few valium sandwiches and off I go back to XDA again. I read a loooong series of "Missing IMEI" stuff and there's CubZ again with an IMEI/EFS fix guide guide...brilliant! And it WAS brilliant, and clearly he helped tons of people (kudos, man). But I had messed up MY phone in the time-honoured "right royal" way - worse than his guide could help me. My IMEI was Unknown, my EFS was empty, My SIM wasn't being recognised, no network info or signal...nothing. But genius that he is, he CubZ DID post a Combination file that gave me a base to keep trying on when firmware after firmware had failed almost immediately with errors either of pm.bin/abort or cm.bin/abort.
I almost wore the print out on CubZ guide, I read it so much and tried so many times. Then...I see people saying things about U1, U2 and U3 firmwares. Turns out you shouldn't mix the two. I got that snippet from CubZ too. More research and the little coffee-fuelled connections in my brain are like.....ok....
My ORIGINAL firmware has in its name "U1" and there are similar ones with "U2". Might that be it? My phone has been screaming "DEVICE 2 FIRMWARE 1" (or something like that) at every aborted 'original firmware' installation via Odin and download mode that I've tried, including the EXACT firmware that was on my phone the day it was unwrapped and I danced happily round the room with it.
So if DEVICE 2....FIRMWARE should be 2 maybe? Back to Sammobile. There are firmwares with the same model number, country code, branding info as mine..but with a "U2" where mine said "U1". But...they were Oreo and Nougat where mine was "originally" Marshmallow.
It's now day three in the Big Mother House. My valium and coffee and running out and my communication with the outside world has ceased. I've had about five hours sleep, my food is running low and I cannot call for takeaway cos I ficked my phone up good and proper. I even....get this....start looking up PAID services to fix this. I KNOW, right!!??
I pick up a Nougat firmware from Sammobile...careful to match model, country, branding AND U2 - wondering if I can match it up with CubZ's Combi file as a base to appease Odin......and then maybe revert to my 'original' stock from that to start another attempt at the IMEI/EFS thing.
It loaded. Odin was pleased with my sacrifice. And lo and behold, it had restored the whole lot WITHOUT me having to go any further with stock ROM reversions. It frickin' worked. I got my signal back. My SIM card was detected. My phone number was showing. My IMEI was showing. My E-Frickin-S was mended. I feel like Judd Nelson at the end of Breakfast Club.
So here's the semantic bit that I hadn't known and that is unclear in many many posts. My phone is now working 100% on stock firmware....but is is NOT REALLY the ORIGINAL software - it's the MODEL......COUNTRY......BRANDING.....LANGUAGE - specific firmware but it is Nougat where my original was Marshmallow, and it is a U2 firmware where my original FW was U1. THAT was the killer difference, it seems. Thanks to all of you who posted anything - many many of you - who helped me get this. It's a compatibility issue detail I've never seen or had issues with before.
I now have G930FXXS2DRDI_G930FXEU2DRB5_XEU
Where G930F is the model number, XEU is the country code for UK and Ireland (even though UK is a nation and not a country - just sayin' ) and the U2 sits there hiding in the middle of the second section of the name.
Which gives unzipped files as follows: NOTE - THESE ARE NOT LINKS.
AP_G930FXXS2DRDI_CL12365438_QB17789072_REV00_user_low_ship_meta.tar.md5
BL_G930FXXS2DRDI_CL12365438_QB17789072_REV00_user_low_ship.tar.md5
CP_G930FXXU2DRB6_CL648265_QB8952207_SIGNED.tar.md5
CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar.md5
HOME_CSC_XEU_G930FXEU2DRB5_CL13061583_QB16917099_REV00_user_low_ship.tar.md5
It's Nougat, but that's okay for now; I got my IMEI, EFS, SIM, BIN, probably ENT, RAC, SUV and BMX too, everything
And now, with my working phone, I am gonna phone the local Chinese Takeaway for food, answer all my emails that popped and binged and tinkled at me when it became resurrected, and leave CubZ with huge thanks and all of you guys with the hope that this helps somebody out there.
And maybe look at backing this sucker up and reverting to my Oreo RR ROM I love so much..... I HATE Touchwiz!!!!
Good luck!

You deleted all files and folders from EFS Mounted partition? how is it possible working?

You are awesome man!
I just deleted the files in EFS, restarted without installing custom rom and my IMEI was fixed.
I'm definitely donating. How to donate to you?
Thanks for your great work!

I think samsung phones are capable of regnerating their efs. But its not working for me on samsung galaxy s6. Guess I am screwed.

Hey everyone, I'm sorry for not responding to anyone in this thread. I've been inactive for a long time. I want to thank everyone for trusting the guide and I hope it has worked for you if you tried following the steps. If you have any questions feel free to ask me.
Also I have edited my guide to improve the reading experience because I see my English was absolutely horrible at the time when I wrote the guide.

oh no. i accidentally deleted the efs partition and it can't mount anymore what im gonna do now. im fvcked up please somebody help me

vigilante said:
Edited in 2022 to make it look a bit better!
Hello people, first I want to say that this is my first guide so it doesn't really look professional but I am doing my best to be clear as possible.
In this guide I will be showing you how to repair your IMEI for free/without Z3X box
So lets get into it.
Its better to start fresh in stock rom
So flash the stock rom first
Now we are really starting,
*WARNING* *TAKE A NANDROID BACKUP OF EFS AND BASEBAND BEFORE STARTING*
Step 1) flash TWRP and flash Magisk (if you weren't rooted yet)
Step 2) now search for a custom rom for your phone download it before doing something or just download on pc and move it later
Step 3) now go to mount and select efs or else your efs will be empty at the next step
Step 4) now go to file manager and goto /EFS
Just delete everything in it, you have a backup anyway *WARNING: DO NOT DELETE THE EFS PARTITION IT SELF, IT WILL MAKE YOUR PHONE NOT BOOTING ANYMORE ONLY DELETE THE FILES INSIDE OF IT SO DELETE ALL FILES*
Step 5) now flash the custom rom for s7 edge i would recommend kingrom, do full wipe at the aroma
Step 6) now reboot your phone, first reboot may take 5-10/15 minutes please be patient and make sure you put your phone in the charger if your battery is low now when your phone is in the welcome screen look or your signal is returned if not just setup your phone sometimes it may take a while if your signal is returned then go to dialer and dial *#06# and look or the imei matches the imei of the box (make sure you have the origional box if you dont have this then open the back of your phone, there is a sticker label with your s/n and imei if imei is not good then skip to step 9
Step 7) now if your s/n is ok skip to step... if its not right then download a root explorer and go to /efs/factoryapp and edit the serial no file with a text editor and enter your s/n there now save it and imei and s/n should be alright
Step 8) Now, for IF the IMEI is correct and everything is fully functional, then delete the earlier made backup of EFS and baseband and make a new one with the working partition, then save it somewhere safe on an external drive, the cloud or on an USB, or just a pc that you will never reset or wipe its data.
Step 9) now for if the IMEI is not correct or this guide doesn't work then I can't help you any further except for if you have any questions, however I found a guide for the Samsung galaxy s7/Edge (if you have s8 then click same link because the thread has a link to s8) by Cubz (thanks to Cubz for his guide)
Link: https://www.google.com/amp/s/forum....ow-to-fix-check-drk-imei-issues-t3379516/amp/
S7/E/8 only and some other models as long its an s7 (edge) or s8/+
******* Some tips when you follow the guide*******
1) when you flash combination firmware and it gives you errors then dial *#1234# and look at the cp it should have UX in it (X could be 1,2 or 3 download the correct firmware with the correct bootloader version you can upgrade from u1 to u2 and u2 to u3 but not downgrade from 3 to 2 or 2 to 1
2) if it didn't work then flash back to stock and fully delete everything in efs folder then retry (this is actually just guide B) its better to follow the guide above
3) if you got bootloader exception error then keep tapping the home button fast until it reboots then just manually reboot and enter download mode
The first method was tested and worked on SAMSUNG GALAXY S7 EDGE SM-935F it may work on other Samsung devices and maybe other android devices but I cannot guarantee that it works on your device
** I take no responsibility for any damaged device, make sure you take a back up so you can go back to the state before you started following this guide!**
If the device gets bricked then always flash back to stock, if you cant enter download mode then just wait until your battery drains and then when you put it in the charger it may start up automatically so enter download mode fast or if you got bootloader exception error then keep tapping the home button fast until it reboots then just manually reboot and enter download mode

Please donate and like this thread if you found this helpful, I have experienced this problem my self and it costed me €60! I said NO its too expansive so then I found this solution and now I am sharing it to the world, I could have let this guide cost €61 but my guides and solutions are free a support would be great for finding this out
Happy flashing and please confirm in the comments below if it worked for your device or not

Have you created a back up of your efs partition? I have clearly written it in the guide with all caps. If you haven't made a back up, please do so to avoid getting into this situation in the future.

Anyways, I'm sorry to hear you got your self in this situation. Even though it has been a long time since I did this kind of stuff, I still remember that it's possible to fix this issue. I am sure that I have been in this situation before my self and that I somehow managed to get it back. Try to back up all your data, then flash stock rom with CSC file and not Home CSC

I'm sorry for being so stupid because I continued without performing a backup in TWRP, I forgot to back up the EFS, and when I panicked because I was already screwed up, I deleted the efs folder—which is incorrect. I deleted the efs partition before I saw this thread. And now it always says, "failed to mount /efs (invalid argument)" and I've done everything, and it seems like everything is done, I have no idea what to do. I haven't slept for four days and there is still no hope. but my phone is still okay with the stock firmware, but it always restarts. I did almost everything but still nothing
My phone's current csc code is THL (Thailand), but the original is XTC (Philippines), which is my nation, thus I'm curious why THL? of course I flash the right firmware which is the csc is XTC but if I check the CSC the CSC is still THL. I tried to change the csc using tools, but it cannot be change. There may be no hope. I'm worried about losing my phone, yet I'm to blame.
If I lose my IMEI, it won't matter. But the thing is my phone is always restarting every minute.
(can someone know how to disable auto-reboot so i can still use my phone even the EFS is damaged?)
ALSO THANKYOU FOR YOUR REPLY! I APPRECIATE IT!
EDIT: OH I FIX THE EFS PARTITION. NOW MY PROBLEM IS HOW TO GET OUT FROM THIS DARKNESS. HOW CAN I FIX THE IMEI AND BASEBAND WHAT EVER? HMM. BUT I WON'T GIVE UP

Try to download this tool if you haven't already: https://samfirmtool.com/
I like to use this tool when flashing stock rom because I can download specific versions of stock ROMS and also enter the correct region in it. And to top it off the download is really quick (depending on your download speed of course)
Enter your device model number and at region enter the csc you need. It should download the correct files with the right csc. However, I did find this thread saying it is impossible to change your csc to XTC, but it is always worth a try.
If the CSC is XTC then try to follow this guide again to fix your EFS.
If it is not XTC then try to install a custom rom for your phone that has an aroma installer that allows you to pick a CSC, it might also help with the EFS problem but I am not sure.

Since you have mentioned that your EFS partition is fixed, try to follow the guide again but correctly this time. Maybe it will work this time.
Can you tell me how you checked what your CSC is? And which phone do you have? In case this didn't work.

My phone is Samsung Galaxy J8. Before i start to flash custom rom, I took a snapshot of the device's hardware information and discovered that the csc is really XTC. I have completed all the necessary steps. I did everything right, but nothing actually changed. I'm so exhausted that I might just give up. I appreciate your assistance.
If I can't retrieve the imei, it's fine, but unfortunately my phone is always restarting
EDIT: MY PHONE IS NOW FIXED. THE SIMS ARE NOW WORKING, THE SIGNAL IS BACK AND I FEEL SO HAPPY. HOW DO I FIX? WELL I USED THIS METHOD, I DELETE ALL THE FILES FROM EFS FOLDER (NOT THE PARTITION JUST THE FILE INSIDE OF IT) THEN I FLASH THE LATEST STOCK ROM WHICH IS ANDROID 10 BUT THE CSC FILE IS FROM ANDROID 9 AND AFTER THAT I USED TFT SAMSUNG MODULE WHICH IS VERY HELPFUL AND LEGIT TOOL AND ITS 100% FREE!. THEN I FIX THE IMEI AND BASEBAND USING THAT TOOL AND YES THAT SOFTWARE IS A BEAST. AND NOW ITS WORKING PROPERLY. IT TOOK ME 2 WEEKS TO SOLVE THE PROBLEM BUT IN REALITY ITS VERY SIMPLE HAHAHA! IT SAVES ME FROM SPENDING MONEY JUST TO SAVE MY PHONE BUT I DO NOT KNOW THAT I AM THE ONE WHO WILL FIX MY PHONE HAHA HOW COOL IS THAT. JUST DON'T GIVE UP NO MATTER WHAT HAPPENS!

THANKS TO THIS METHOD AND TO SIR VIGILANTE.
EVERYTHING IS POSSIBLE JUST DONT GIVE UP EVEN YOU'RE TIRED.

need four file repair firmware please N920TUVU4EQJ3

desperately trying to un brick my note 5. I've been trying for weeks now to recover my phone after a rooting mishap had caused loss of imei and baseband. in the process of attempting to repair that issue I have managed to completely soft brick the damn thing. I have been to the deepest corners of google in search of this specific 4 file repair download and can not find anything that is free. I've even signed up for accounts on gsm flash and the like only to be disappointed that signing up wasn't enough to get the files I need... if anyone has a link or the files themselves I would be very thankful for there help. to be clear I can not flash standard stock rom through Odin. the process completes and the phone boots but than erases at 32 percent and will only boot to recovery with dm verity error or download mode. I've tried a few different official stock roms. I've tried flashing the one file home.tar as well as un packing and flashing boot, system, modem, cache neither of which have worked. I can't find a hidden image file to remove before flashing so unless I'm missing something im out of ideas.. the repair. firmware seems to be my last hope... also to hell out anyone trying to assist. I flashed a. efs file when trying to restore imei and that in turn re enabled frp lock.. so I believe both frp lock and oem lock are enabled. so any combination file or modified at all is out of the question... I believe it's repair or nothing. there are a few free 4 file repair downloads out there but they aren't the same number im not sure if there are any compatible enough that I could flash one of them and they work? so if any one knows of other models compatible. with the SM-N920TUVU4EQJ3 let me know so I can try to get this mess sorted out. I apologize if this has been asked somewhere els or if I'm in the wrong forum. but this seemed the most suited for my case. thank you to anyone who may be able to help

anybody?
is anyone able to help me out?

Hi I had the same issue with my note 5 SM-N920T I managed to fix it by downloading a pre rooted with SU rom from xda I also had the twrp custom bootloader installed first for some reason my pc still picked up my phone and I was still able to upload the rom to the twrp location on the device. having done that I was the able to copy the zip file over to my device and flash it.
When I had the rom installed I was then able to download the original android rom (android 5 in my case) from sam mobile they also had the most up-to-date android 7 rom as well for the device then it was just a case of using android repair to un root the bootloader and install the original android bootloader this was also on sam mobile.
Then make sure the phone has a full battery as flash the stock firmware as you would normally with odin and have the latest Samsung drivers installed on yore system or it will fail.
After the flash has taken place the first boot will take some time my note 5 took around 45 min's and then when fully back up and running I had to spend a good 2 hours reinstalling and updating all my software and OTA updates.
