First of all I wanted to let you know that I've tried everything in my power before I post my problem here. I found it very difficult to understand some solutions that are discussed here. But after 3 days I have decided to try it here.
I just bought a LG P920 for my son (can't afford a new phone now) and he got a present. A car you can control with your phone, but it didn't work because I thought the android version wasn't sufficient enough so I flashed a custom rom:
CyanogenMod -version Android 4.1.2
10-20121227-NIGHTLY-p920
After several other roms, and I tried a lot, I still have no baseband. It says: unknown
Which rom can I flash to get it back? Or is there an easy way to get the baseband? I saw some tutorials but I found them very hard to do. I really hope somebody has a solution for my son and me. Excuse my english, I'm from Holland
You may simply need to set up your APN; my tutorial covers that, and also flashing baseband. I have not tried CM so I am not sure if there are any issues there, however.

Thank you very much for your response and I've looked at your tutorial but I have really no idea what I'm supposed to do. Rooting and flashing a custom rom is easy but this is something out-of-my-league.
Wich flash tool do I have to use for flashing a baseband? How does this go? I'm really sorry about this but this is completely new for me.

I post it twice accidentally ...:silly:
You would set up pc drivers as in part 1. Then use Flash Tool to flash a baseband (.fls file). There are a few included in the download files, or there is a link there to other basebands for different countries. You do not need to install ICS or the custom ROM if you do nit want.
You may not need to do all that; you just might need to set up the APN for your particular network and SIM if you have not tried that already.

Now I figured out how to use the SmartFlash Tool and as soon as I want to start the flash process the app crashes
You have to use the program in XP mode and run it as admin.

You're right and it worked. It all went well and I got the complete green line at the end, so I thought this is it. I'm back to stock!
But now it says when I check
Android-version:
2.3.5
Baseband-version:
L6260_MODEM_SIC_01.1042.00
Kernel=-version:
2.6.35.7+
and still no possibility to make a call ... it still says: No service
Did you set up your APN?

How do I do that? I also checked my imei number and there's isn't one. So that was the issue all the time. I've searched a way to retrieve it and tried it. But I got stuck at point 6. Got this from here: http://forum.xda-developers.com/showthread.php?t=1734330
Restoring IMEI
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4. Select Port Settings -> Select CP Image Download
5. A new device should appear at let it install
6. Open Tutty and select serial protocol. Click on open
7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8. Type at%imei, it should display a dummy IMEI
9. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10. Reboot phone
I have never lost IMEI so dunno there. APN is in system settings, more...

Dear friends
I used lg updater but after that I lost the signal
When I checked *#06# it didn't show me the imei
When I go to about imei it show 0
I searched the problem on 3d I didn't found any one have this problem
But I found some 2x have it and they solve it by baseband flashing
So did any one have the same problem before and how dix you solve it ?
Thank you all

any one can help me please
very similiar problem, imei empty, id not found.
is not detecting the sim card
and the only way to switch it up is with charger of the wall conected imposible to do with the usb
You should see the IMEI under Settings -> About Phone -> Status
Att flashed kz with lg update
I am having the same issues as you guys.. I flashed the KZ file with lg update software as explained in the XDA thread but I could not get the process to work right. My phone kept disconnecting at 28% and it would not turn on no matter what I did. It would only make a short vibrate as if it was turning on, and the computer would notice it but only for a short time. And never once did a light on the screen, or LG logo, or anything at all ever appear.
I figured I had really screwed it up, but when I plugged it into the wall it booted up perfectly. All my data was in tact and the rom i had flashed through cwm was still there, not the kdz file that I flashed with the lg software.. I noticed that my sim card did not come up as being in the phone at all. I looked in system setting status and noticed that all info related to my imei said unknown. I opened up the mfg app (277634#*# from the phone app).. Under "version info" then "factory version" my phone now says xmm6260.. It always used to say p925..etc... Even after flashing the zip to debrand from at&t this never changed from p925 even when every other aspect of my phone has.. I was hoping maybe once I put in an activated sim card everything would be fine and my phone would be unlocked which is why i flashed through lg software.. But seeing as how other people are having this similar issue and their phones not seeing the sim card, well im looking for some advice.. Should I try and re flash kdz file through lg software again? if i do, im going to do it on my XP computer this time, not Windows 7..
Just wanted to add that I did try wiping data and cache from cm and no dice.. Root and CMW work fine but no matter what I do, if my phone is turned off, i cannot boot up or boot to cwm or boot at all unless i plug the phone into a wall carger and then once its on it stays on and i can unlug.. SORRY ABOUT THE LONG POST, THANKS IN ADVANCE FOR ANY HELP..
Hello, I am having the same problemws as you.. Have you found anything out yet? I'm trying to get some answers.. Did you try re flashing kdz with lg update?

Im having same problem, has anyone found a solution?

imei missing
Is there any soltion? Please.
Reflash the phone.
Take out battery. hold down the up key, plug in cable to computer.
Wait till it installs or activates the necessary drivers. eg usb protocol etc.
Then run the recovery via lg tool by entering your imei number in the application.
This will install the latest stock version based on your imei (including baseband)

Thanks, I tried but it did not work.
I tried everything possible. KDZ flashed about 20 times. Flashed bin and fls files many times. I do not know what more to try. When I put androuid 2.2 After a while the cell phone turned on appears IMEI and IMESV, but disappeared again after reboot.
I put the phone in the CP - USB (3845#*920# port settings cp-usb) mode and I connect with hyper terminal when I type AT%IMEI my modem gives me IMEI. When I type AT%IMEI=? back to me is: [IMEI part1 [7] + IMEI part2 [8]] but I do not know how to write it. I tried all possible combinations and I still write IMEI write error. (AT%IMEI=xxxxxxxx + xxxxxxx AT%IMEI= x, x, x, x, x, x, x, x, x, x, x, x, x, x, x, ......) I found [LGFlash Tool 1.0]LGP920_20120213_Download_WriteIMEI.dll at the CSMG server and I tried with LG flash tool so that instead of stock dll I put this dll but it failed. It gives me an error not read IMEI. There may be a BIN file that is used whit it??? Here's the dll if anyone wants to try.
All this hapend after simple reboot. I found service manual for LG internal use it says that this could happen becouse of fault in firmware, and that after write IMEI firmware should be updated to V21A to prevent this to happen. So some early firmware cause it.
I dont have warranty.
sorry for bad english.
Interesting.
When you run the official recovery tool and it asks you to enter your Imei, does it go ahead with the process and fully complete 100% with the flashing?
Do the problems then still occur? If you can get your phone to turn on at anytime, have you tried a full factory reset after that?

Yes it completes at 100% everything is ok I can turn it on, off, go into recovery and everything. Device is working perfect but android cant see IMEI, that is writen in eeprom. I tried factory reset numeros times, no help. When i start lgupdate official tool, tool also reads correct IMEI from device.
Seems an issue with the baseband updating/corrupted, although the lg tool flash recovery should have updated this as well. Have you tried the other flash methods (try one of the kdz roms in this forum. eg v21a for europe gingerbread) and use this flashing method (you would need to block the lg updater from accessing the net) There is a tutorial on this in this forum. it works via forcing a rom update and redirecting it into the lg flash program

I did that metod too. There is any metod here on this forum that I didnt try. Thanks for help. I dont know is it baseband or CP chip problem.
This may be guesswork, but if the baseband is flashed in a specific area of the phones nand space, perhaps the nand blocks there are corrupt which causes it to fail. Perhaps with some additional tools, it may be possible to format this area, marking the bad blocks as bad preventing the baseband data from writing to these area's. Just guesswork here.
Have you tried flashing other baseband versions seperately

Hi,
I have the same problem and tried almost everything written in this topic but didn't worked.
hyperterminal seems to be working for most of the optimus models but doesn't work with p920. I tried all the port settings and everytime got "IMEI WRITE ERROR" message.
any new suggestion?
Hey,
So I mainly opened my account here because of this problem, and I need to fix it as fast as possible...
I rooted my phone, that went fine. Then I tried to upgrade the baseband to the ICS ROM, which didn't really work (I followed all the steps but when the phone turned on it was the same version..) so I skipped that step to install a new ROM. Installed the ICS ROM on my phone, but then I wanted to install the new baseband (P500-v20G) so I will have my network back. I ran LGMDP-v1.5.exe but it didn't detect any ports. My computer doesn't detect my phone either. And on a different computer my friend tried to help me, it connected but the baseband upgrading still didn't work. Also now I get plenty of errors when my phone is on about processes closing (didn't happen after the first time I installed a new ROM, but after I tried different other ROMs it did).
Please help me :crying:
So my two problems: phone not connecting to the computer (I'm sure it's a problem with my computer) and the baseband problem.
Problems solved.
I can say only one thing.. Please search and read all important and sticky threads before experimenting with your phone. Atleast have proper knowledge. These kind of dumb issues are already been answered a thousand times.
Temporary fix for your Baseband.. use the first link in my signature.
Flash it. AND Due to old scripts.. it does work with new recoveries.. so in that case use root explorer.. unzip and paste in /system/libs.. set permissions right.. thats all.
About how to upgrade Baseband and computer problem.. search and solve it yourself.

Check you APNs ( Access Point Name ). Setting is located under Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names on CM7. I think on ICS and JB it's under Settings -> Mobile Networks -> Access Point Names. You mentioned a P500, so you're carrier should be listed as ATT under the APNs list.
So basically my imei has changed to 0 and baseband to unknown, Suddenly one day I lost signal and network.
I tried flashing different roms and radios and nothing worked, then i researched and found out that I will have to fix my efs which is possible by QPTS.
I need to know how to put my phone to DIAG mode to use QPTS, currently using cynogenmod 10.1 nightly on my Samsung SGH- I727 At&t Skyrocket.
So tellme how ?
Will I have to return to a stable release to use Diag or any other rom?
p.s i cant switch the stock using odin as it gets stuck in a boot loop but can flash other roms.
So if you know about enabling Diag mode on any other rom please tellme how and what rom is it.
Please help to restore my corrupt efs (which i read happens sometimes with flashing roms). If you know any other way also.

I have a keystr file, whats missing is the nv_data.bin and other such files which hold the imei info.
You can rewrite you imei (if you have it on the back of your phone or in phone documents) with these tools (software & hardware) http://goo.gl/54mtk. Here's a guide for it http://goo.gl/wtW29.
Also you could try this alternative http://goo.gl/ghcJn ..
None of that is free..
And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

I have no idea what you are talking about, but below may be a method for getting into USB Diag mode.
Just to be clear: I have not read this thread as it is for Verizon Galaxy S3. If you try that on our phone you will do that on your own risk.
I simply suggested you got in touch with amoamare and see if he can help you or add support for our phone in his app.
Some phones must be put into USB Diagnostics mode to do the
unlocking. On your phone, enter *#9090#. Does a menu open? If yes,
select - [1] Uart_null_usb_diag (usually the first option). Depending
on your phone model, this may be called differently. Once selected,
watch for words like “USB Diag” and select such an option. If entering
*#9090# doesn’t do anything, try *#7284# and see whether you can
find anything similar to - [1] Uart_null_usb_diag. If there is no such
thing, ignore this entire step!

hey everyone, im new here, just got a Samsung s8+ last week. had it rooted and all working well until today, had problems so i went to reflash twrp and when was unticking auto reboot in odin i accidentally ticked "nand erase"..... and i didnt notice until it was too late.
Now i cant get into recovery mode, i can get to the download mode but it wont flash the twrp at all it keeps failing. all i get is a black screen with samsung logo when i try to start it up. i am downloading factory firmware as i write this and going to see if that'll flash. any help will be appreciated.
thanks in advance, hope this is the right place to post it.
Hey
If you can get to download mode,you just install the original firmware from smartswitch,I think you have that option to recover from that program,and install the original firmware.
Or just do it in Odin and find the firmware on SamM.
Lots of work for you,but thats the only thing I can come up with.
Then you have to root it again and everything with it.

No worry
You just have to install Microsoft visual c++ 2008 x86,after you have done that,no more errors in smartswitch.
Try that,and let us know
Long time since I used Odin now,but try the first thing first

Morning Mate,
Smart Switch (and KIES on Win 10) requires some old stuff to work. Install Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) from https://www.microsoft.com/en-us/download/details.aspx?id=5582 My advice however would be to try and flash your carriers stock firmware with ODIN or if you want an easier way you can use KIES by doing the following -
- Install C++ 2008 SP1 from link above to get it to work on Windows 10
- Install KIES www.samsung.com/au/support/usefulsoftware/KIES/ - I'm in Australia so that's my closest but you can still get it from there no worries.
- Also select install 'unified driver' during install if you have not already installed Samsung USB drivers to your PC
- Fire up KIES and from the top menu select 'Tools' and from the drop down menu select 'Firmware Upgrade and Initialisation'
- Enter in your model number - for me it's SM-G955F (make sure model is all in CAPS or it will not work). Now it will present you with a S/N dialog box. This is the tricky part if your phone is bricked. Chances are you have not written down your serial number. You can get your serial number from the back of your phone towards the bottom in really small print, or you can get it from the box it came in from purchase if you happened to have kept that.
- Enter in the serial number and follow the instructions, it's easy as. This will install your stock firmware and you can start again. Provided there is no damage to the phone this method will always get you out of the proverbial as a last resort and it's faster than downloading firmware from updato.com or other places.
The fastest way is by using the SamFirm tool to download but it takes some knowledge and I have lost the link to where I got it (the link at XDA is dead now and refers you to updato.com). The method with KIES above will always work, is fairly fast and pretty easy for the newbies or experienced alike.
Hope this helps, let me know if you need any more assistance :good:
Thanks heaps mate, im also in australia too. have installed all the software and is updating and installing as i write this, all seems to be going well so far, thank you so much your a life saver i was starting to worry as wtf i could do with this brick haha i will keep you posted and let you know if i have nay problems. Thanks to everyone else for their help and contribution this forum is awesome. What would you recommend in regards to rooting the phone again use the twrp recovery and magisk-v14.0 root?
thanks again
I was just about to write a post about how it wouldnt work.... twice in a row it kept failing when it went to install and initialize... 3rd time lucky it ****ing worked! i have a stock phone now all working sweet. Thanks so much to everyone you guys are literally lifesavers!

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/+

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.
