I have a I9020T, I was on CM7, Oxygen etc.. for the last few months. But i had some stability issues, SOD's , reboots, freezes etc.
So i thought I'll go back to good old stock. i downloaded the stock rom's from the general section, and flashed them
Now i notice that i lose signals, phone's display is messed up during incoming calls( I can only see the the status bar, Below that everything is black, But i could just answer the calls by swiping the screen), Losing signal happens almost every alternate day.
So all i wanna know is, Are all these known bugs or is my phone screwed up due to too much flashing?
I am totally unrooted now.... I wiped everything including sd card and have tried atleast 3 different stock roms already.
Anyone else having these issues? Any solutions or fixes.
Hi,
Have you already try ODIN ?
He's able to put your device as it was before all changes.

I thought odin was not safe? That's a last option right because its the same as flashing the stock rom through recovery?
I've already use it a lot of time. I was using it on my spica by thé past.
With thé good files and the good tuto it might work.
Here, in France, we use Odin to restore a clean phone.
If you decided tu use it, you will put your device like ait was new . And you will have to flash thé recovery and root him.
I late you search for some comments from over users.

can you supply links for the nessesary files for i9020t???
I'll find the folder to download here (need to register for DL) : http://www.samfirmware.com/mobile.htm
I'm looking for link for ODIN download.
I just talk about a way to might resolve some issue, use it a your own risks.
Be careful with your device version. Save your data (SMS, Pictures, Music...)
Using Odin shouldn't remove data from "SD CARD" but might be safe...
Edit : The link of download ODIN is in the same line. (FLASHER).

Can you give me link of proper instructions for ODIN, I searched here and the thread in Android development doesn't seem to have the necessary files for I9020T.
I don't know what kind of difference there is between i9020 A and i9020 T.
I'm running a i9023.
In the website I'd give the link, you'll find a FlashGuide with explain what is necessary to do in order to use Odin.
If you register there, you'll able to download the guide and more informations about the way to use.
I can't give you more answers, sorry.
Try Matr1x v11.0 CFS ;D
Do you think i9023 & i9020T are running the same build ?
I wonder.
Because, I've just get a look on the following thread and the two devices seems to work with the same baseband.
Look here : http://forum.xda-developers.com/showthread.php?t=1056062
I let you wait for another feedback from users. I just should want to give a way.
I hope you'll manage to get back to Stock.
Alright, so i am having a bit of an issue. And it's probably because i'm a complete noob....
So, I have a new GS3, and wanted to give my (already rooted and flashed with Cyanogenmod 10) Skyrocket to my mom to use on Simple mobile (a company using T-mobile's towers).
I read that you can flash radios for T-mobile onto the phone, and so I figured everything would work.
Here is what I did.
I unlocked the phone while in Cyanogenmod10
Flashed LiquidSmooth RC9 - read it had less bugs
tried flashing multiple Tmobile Radios
I get NO service. I cant pick any of them up..
Baseband comes up as UNKNOWN...
So i'm currently downloading ODIN and going to try to flash to stock and just start from scratch...
Any suggestions on what to do?
Do you still have an imei?
Try unlocking the phone after you've gone back to stock. I don't know how you did it with cm10. I don't think it works with anything but stock.

No, the IMEI is blank when i do the *#06# code....
also, when i put the simple mobile sim in the phone, it automatically came up asking for the network unlock code. That's how i was able to unlock it.
Did you ever backup your imei? Flashing back to stock will hopefully bring it back if not you may have some issues. Also as mentioned above it's better to unlock from a stock ROM or at least stock based.
Alright, Flashed to stock, IMEI is back (thank god), and i'm getting service.
Now here are the issues ahead of me, and any help would be greatly appreciated.
I am on STOCK ATT ICS Rom.
I GET SERVICE (however, it's only 2g) i know i need to flash the radios for Tmobile,
Was going to use this ---> Blaze_4G_LB7_ICS_Radio_MOD ...... Direct DL, CAN BE USED FOR T-MOBILE/WIND ON ICS (from the skyrocket reference thread)
First i know i have to root, install CWM, all that.
Now, should i flash a custom rom? If so, which one would you suggest. ( i assume, i have to give her ICS, not JB, right?)
Also, you said backup my IMEI, i'll look this up in the meantime, but if you could include a link in your post on a how-to just in case i dont find it, i would really appreciate it.
Also, is there anything else i should do to get this working properly?
thank you very much for all your help.

Custom ROM is your choice. There are a lot of JB ROMS that are pretty stable. Also a new stock JB leak in the dev section. As far as backing up your imei. You'll need to root first as soon as you do get a file explorer and copy the whole EFS folder to your external SDcard. Then also copy it to your computer. The imei is held within the EFS folder. From now on do this as soon as you root BEFORE you flash anything. lol

Thank you very much! I'll start rooting now and back it up immediately. I would love to give her a JB rom, mainly for google now. However, that radio is for ICS. Is that going to cause a problem? or will it even work on JB?
I've been on JB for months using an ICS radio. I'm on ATT so I can't say for certain but it shouldn't be an issue. Just go to the DEV thread and spend a few hours reading up on what's available. Like I said most of the ROMs are pretty stable at this point.
FYI, on skyrocket the IMEI is stored in mmcblk0p18 and mmcblk0p19, not /efs partition. Might really want to back those up, especially before attempting a usb unlock. The /efs only really stores exports of certain properties from mmcblk0p18.

Thanks for the heads up. lol I thought for sure they'd be stored in the same place they where for my SGS4G. So what is stored in the imei folder in EFS then?
I am at a loss.... I rooted my phone and it was awesome! So I followed the instructions by lumin on how to flash a custom kernel and rom....didn't work...so with the help of one of the members here, I reverted back to kj6 stock gb with heimdally one-click. rooted the phone with super-one-click....and the phone will not connect to tmobile's network. I restored the original efs backup, which then gave me the correct imei, but I have no signal...wifi calling won't work now, and now I cannot do anything...but receive texts... I tried the method given to me by another member through pm, and it is as follows:
From what I've read, this will delete your IMEI information and replace it with generic info, which will allow you to use the network, but might bar you from high data speeds.
In the dialer, type this exactly: *#*#197328640#*#*
This will put you in factory debug mode. Perform the following steps exactly:
Click 6) Common
Click 6) NV Rebuild
Click 1) NV Rebuild
If there are any more options just continue through them until the phone completes this process (I can't go any further on my phone for fear of changing my currently good IMEI. Then reboot the phone.
I did all this, and it did nothing... I don't know what to do! I've never been more desperate to have a phone because I am away from home and a poor college student...so I'm just really needing some help. I'm at the end of my rope. Please help!:crying:
I really need help! Will SOMEONE help me please?!!!!

Hi.
I recently flashed the iNfinity HD V2 rom on my Blu Life Play.
Since then I have not been able to get my sim to be recognize in the sim 2 slot.
It worked before I flashed the rom and I'm at a loss as how to resolve the issue.
Any help would be greatly appreciated.

I'm no expert on this, but here is my guess.
There are 2 versions of the Blu Life Play. One of which supports 850/1900 3G bands, the other working with 850/2100. Both of these versions of your phone have 2 sim card slots. My guess would be (and odds are I am not right) is that you flashed the ROM corresponding to the opposite version of the Life Play that you have, and that caused some sort of issue. Like if you had the L100a, you might have accidentally flashed the L100i ROM, or the other way around.
Check the thread or page that you got the ROM from. That 2nd SIM card slot issue might be a known issue. Usually ROM developers will post a "What's Working" and "What's Not Working" section on the thread or page they made for their ROM. Check to see if the SIM card issue is in the "What's Not Working" section.
Hope this helps!

Thanks for the reply.
That could be a possibility.
I have gone through the thread and I don't see anything specific to my problem but something similar.
I should I have been more vigilant before I flashed.

If it is really necessary that you have the 2nd SIM card slot, just go back to the stock version of Android that came with your phone, and then from there try to get another ROM. That way, even if you are unable to find another ROM that doesn't have the 2nd SIM card issue, at least you will be running a version of Android that does support it.

My main issue at the moment is actually getting the phone back to stock; every time I flash it there seems to be remnants of the old rom.
I cant' seem to get it back to stock.
I managed to get the phone back to stock including the recovery.
I still can't get the phone to recognize the sim.
After reading some threads here I think I flashed a rom for L100i instead of L100a.
I think the problem is to do with the modem.
Can anyone help me please?
I think I have the problem narrowed down to not having a IMEI number.
I have no back up of it.
Is there any way I can get a the IMEI back on my phone?
Phone is no longer rooted and having trouble rooting again.

If all you did was restore a recovery-made-backup, I don't think that will restore original baseband and stuff. If this is how you got back to stock, that means that although you are running stock BLU-Android, you are still using the broken L100i incompatible baseband.
I am not sure if this phone is compatible with ODIN, but if it is and you can find a tutorial on how to restore your L100a back to stock with ODIN then this is what you want. I am not sure what ODIN stands for, but it's a download tool used for not only restoring a phone's android operating system back to stock, but the other things that a plain old recovery-backup doesn't cover like kernel and baseband. ODIN requires a Windows PC with the correct phone drivers installed. So in this case you need the your phone's drivers from BLU on your computer, so that when you plug the phone in it is recognized as a BLU Life. Again, I am not sure if there even is an ODIN image for your phone since generally BLU phones are not that popular on XDA, but if there is then follow the instructions and use that to restore back to stock instead of just using a recovery backup.
IF YOU DO FIND AN ODIN IMAGE FOR IT, MAKE SURE THAT YOU DO NOT MAKE THE SAME MISTAKE OF INSTALLING THE "I" VERSION INSTEAD OF THE "A" VERSION! MAKE ABSOLUTELY SURE THAT THE ODIN IMAGE IS THE EXACT ONE FOR YOUR PHONE!!!!
EDIT: I just re-read your post and realized I didn't exactly answer your question. Sorry about that.
You should do the ODIN thing I mentioned above, just to make sure that you are on the right baseband. However I do not think this restores your IMEI as well. I Google'd how to restore a lost IMEI on an Android phone and got a couple articles on how to do so. One of these articles tells that CHANGING THE IMEI OF YOUR PHONE IS ILLEGAL!!!!! However It doesn't sound like this applies to you according to what you said, because you are only trying to restore a lost IMEI number, not change an already existing one.
Have a look at this article.
Good luck! :cyclops:

All I'm trying to do is get the IMEI that came with the phone back on it; nothing illegal.
Mobile ODIN is not compatible with my device.
I would like to get back to full stock; can anyone help with that please?
I have seen that SpFlashtool might be useful for me.
The only problem is is that I have no experience with it.
Can anyone give me some pointers on how to use it safely?
I'm not sure if people have any interest in this, but I think I have have the problem resolved.
I flashed octarom_kk_iq4410_v3_fixed which seem to give me a baseband then I used SP_Flash_Tool_v3.1328.0.183 to flash a secro.img.
after all that my imei's were restored.
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

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.
