All,
Noob here as far as Android goes. I picked up a Galaxy S Captivate a few months ago from AT&T and I got a notification saying Froyo was available. Of course, Samsung made it near impossible to do, so I figured "I'm a computer programmer, I can do these kinds of things".
Using Odin, I put on a version of Froyo. It was... not a good ROM by far (I didn't know all the great ones were here) and after the 4th or 5th random crash, I decided to try something different. However, at one point the phone bricked. I was finally able to get Odin to push back 2.1 Eclair (the stock AT&T version), but since then, I get a "SIM Network Unlock Pin" prompt. I followed the instructions to grab the unlock code from the bml3.back file, but it doesn't work. I've tried upgrading to various Froyo's, but they don't work either. AT&T tried a new SIM card, but that didn't work.
At this point, my Android abilities are done. I have no idea how to fix my phone. AT&T can't help and of course, Samsung will charge me for a repair (I have no idea how much that is).
Can anyone think of a way to get rid of the SIM Network Unlock PIN thing? This is a legitimate phone on a legit plan. The Continuum 3.5 Froyo runs great, it just can't see my SIM Network card and a phone without that is...well, bunk
Thanks for the help, I wish I could retrace all my steps but I was an idiot and didnt write it all down.

I have never heard of anyone overcoming a lost PIN issue without completely reformatting the phone and reinstalling a ROM.
Try flashing a new 2.2 rom and using the froyo unlock method in the dev section (http://forum.xda-developers.com/showthread.php?t=831569).
Since you mentioned you're a programmer, I'm going to assume you're comfortable with adb. Make sure you back up /efs/ to your sd card, then again to your computer before you try it as rom flashes will typically not overwrite this partition. I suspect your nv_data.bin or some other part of your /efs partition is messed up, which is why flashing most roms won't fix it. I'm not sure if the one click stock odin will do anything, but it's also worth a shot if you haven't tried it yet.
There's also a backup of nv_data.bin in /efs, you can try copying that over your existing nv_data.bin and rebooting to see if it helps.

Thank you thank you thank you thank you. That was exactly it. I now have a phone again!
This place is great, but it's a bit overwhelming when you first join. Couldn't find that article on my own, but it was there!
Cool, glad to hear you got it running again.
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.
Sent from my SAMSUNG-SGH-I957 using xda app-developers app
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?
Hi, I'm at a road block here... I've googled just about everything you can think of, tried just about everything you can think of, nothing is working. : /
I have a Samsung galaxy S2 ( SGH-i757m, bell version ) that I have rooted, I have installed a custom rom( DexRom 3.0 ).
Issue is, I go into settings>about>status, I look down at IMEI section & for my IMEI number, I have " 0 " ( IMEI SV : 02 ), I've tried restoring the EFS folder, tried using HCtool ( says my phone isn't compatible ) I've also flashed another rom, even stock, nothing's working. It's frustrating because this phone doesn't have the typical nv_data.bin file or what ever people say to edit. Currently I am backing up the device with Qualcomm NV Tools, I've tried to hit the button " Write IMEI " ( and yes, I am using a legal, unique IMEI, the one that's on the back of the device under the battery ) & it acts like it did it okay, but then I go check the device.. Still the same thing, IMEI:0 IMEI SV: 02. I've done a reboot, even let it sit for a couple hours. I also tried using a USB UART device ( I used my teensy 2 - arduino basically ) to help aid my issues, nada. But then here's the weird thing, I can still text... If someone could PM me & detail what the issue is, or how the thing is laid out ( as in, what file(s) contain IMEI info ) anything would be appreciated! thanks.
Has anyone been able to solve this problem? I am having the same issue with my phone (SGH-I757M, Bell). The IMEI was there yesterday and now the phone only shows 0 for the IMEI and 01 for IMEI SV (which should be 02). I have yet to try anything to fix the problem (backing up data first).

I haven't been able to fix this issue, but I did manage to be able to use it as a regular cell phone... I called my service provider & explained that my phone has no IMEI number & I can't make calls, but I can text... so what ever they did, fixed it. I can now make calls, receive calls, ect. I gotta find a stable baseband rom tho, some texts just don't send & stuff...
I know that there is a way to fix the IMEI, but you need a 300$ piece of stupid hardware... Z3Xbox, witch isn't really worth 300 $ if you're only going to use it once... I hope someone could reverse engineer the z3xbox & come up with a diy solution, maybe with an arduino board or something...
Anyways, wish you luck!
Edit: I still have no IMEI/SV number, but calling works, so I quit playing with it, made backups of everything & called it a day.

I was able to use all functions of my phone without the IMEI... I managed to get the IMEI back by flashing the stock Android 4.1.2 ROM from sammobile.com
I'm not sure if flashing another version would do the same...

I've tried several roms, oh tho I haven't tried 4.1.2 tho. Could you provide me a link to the firmware that worked for you? I'd love to have this thing working again.
* Update * It seems that rogers now wont allow my phone to connect, I try to connect & it says " Could not connect. Try later " So I have a feeling they black listed it or something... I have my sim in a galaxy infuse & it works fine... So I don't know.
thanks

Sorry for the double post, But could you possibly send me a copy of your whole EFS folder? In like a personal message, I promise I will not use your IMEI. I'd figure out how to put mine into it. thanks in advance.
A while back, I lost my IMEI flashing CM10. I restored that back, and got my phone working again, but every time I leave the local area code, my phone says that I am roaming. Being that I recently moved out of state, this means that my phone now says that I am roaming all the time. While this doesn't greatly affect anything, I would like to fix it. The problem seems to stem from my ERI (ERI version: none). Is there any way to repair this?
I too have this problem now. I recently flashed a few cm10 nightlys one after another using the built in updater and I lost my imei. After using the nv-item_reader_writer program and the nv generator I was able to restore my imei but am still without an erI
This is what I did to get my eri back after losing my imei and restoring it. There may be some steps you don't need to do but it worked for me.
1) I flashed a stock rooted TW rom.
2) Next I flashed the VRLF2 modem found here (Click spoiler to see them) : http://rootzwiki.com/topic/34053-firmware-vrbmf1-modemrpmtzsbl-verizon-sgs3-sch-i535/
3) Next, I got my eri back using the forbidden software in this thread(You're going to have to search the thread some but you're on the right page): http://rootzwiki.com/topic/32397-tu...ants/page__pid__1218913__st__220#entry1218913
4) Follow directions in OP of same thread.
5) Once you have you ERI back to 5 and your phone shows verizon network I highly recommend going to Synergy rom thread and looking for the HW keys back up zip. It can be found if you look through the attachments in that thread. Make a flashable copy of your keys with that zip and place on your sd card and in multiple other places for safe keeping.

Thank you for this. I do not need iut currently and I do have a proper NVBackup but you never know . I have it on my Box account just in case and besides I could always help someone that didnt do a proper NVbackup. Quick question. What happens if you flash a 16 GB PIT on a 32 GB Model? Would it brick you or just give you a 16 GB S3? I have a 16 GB model but just curious. I need to read up on this stuff.

Since I had restored my imei with qpst all I did was use the tool to restore my eri. From what I've read it won't work unless you downgrade your modem. I didn't have to mess with the PIT files listed. I don't think it would be good to mess with those without talking to someone who knows more than I do. JMO, I don't think it would end well mixing those up. I also forgot a step, once you're back up with your eri you can upgrade your modem back to whatever is best for you. A lessoned learned the hard way for me. I haven't had to worry about losing stuff like this since the original EVO 4G.
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.

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

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

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.
