Hi there, as I screwed up my IMEI and Baseband, I am now looking for an EFS backup from someone else. With some luck I might be able to get my phone working again.
The reason I'm looking for EFS folder backup is that no matter what I try, I could not get it fix by any methods including trying to inject IMEI through NV programs because it always fail to connect my phone even when my phone is in Diagnostic Mode, not even NsPro in my phone shop either can fix it either.
So if there anyone willing to send his/her EFS folder backup and let me try, you will be my savior, and I'll be in your debt forever
Of course if you are able to pull the IMEI info out of it first that will be saver to you, but I guarantee you I will try to inject back my own IMEI before I insert my SIM into the phone.
Thanks a ton!

Friends I tell them what happened to me! I have a galaxy note N7100 2 and started to install a rom amending the efs folder (something you did not know) as a result I change the imei to 0049xxxxx and good after spending almost a week reading forums got a solusion, not if it was luck or me but I managed to put again flashing the rom imei assassin's. When installing did not give a efs backup and install it all, this rom gives you the option to put the kernel that you want and the modem, I am from Venezuela and trying to install the kernel branded the same rom but I chose the 3rd bottom-up modem. All fine, put me back my imei now had the problem of the signal, it sends me ariza and accommodation. Now a question, if I have signal when reviewing my efs folder is corrupt? I want to go back to have that repaired folder because I can not flash another rom and would stay stuck in this rom, having it bad I would present the same principle failures. If anyone knows how to fix that folder I would appreciate very gusto.Y if anyone has my problem and has the same model you have, this mas say I'll help you with pleasure.
First person to help gets paid for your time...
Problem: I have a s3 i747 from att.
it has 4.3 stock.
I use srs to unlock all my phones.
well when I went to unlock this one it said it had new security.
Usually when this happens I odin this file that downgrades the modem.
well I did it and now I have null imei and unknown baseband
I tried restoring to stock, didn't help. Through kies and odin.
I need to put it back the way it was... can someone please help..... ill paypal you as soon as its working again...thanks
So you're currently at stock, unlocked? Does the phone boot at all?

yes it is still stock 4.3. no its not unlocked. everything works and boots fine. just no signal because of null imei and unknown baseband.
I think I need to just flash a modem via odin....I just don't know which one

There's seems to be a rash of this happening in the past month. You'll probably find that link helpful but first check and see if others found a better solution.
Yes. Flash the 4.3 modem.
As of 4.3, flashing any older modem will no longer work, resulting in an unknown imei and baseband version. Flashing back to the correct modem nearly always solves this issue.
It will be like this from now on btw. You cannot use any modem except the one which matches your current firmware build.
This means our free unlock method no longer works unfortunately. But you can get unlocked for just a few bucks using one of the many services online. I know some are on ebay, but google will find others as well.
I installed cwm and downloaded the modem but im lost from there.
do I rename it update.zip?
Nope, just flash like you would any other rom.
Because you asked about renaming it to update.zip though, I have to ask if you are certain you are in cwm? If you had previously updated via ota it may restore the stock recovery every time you reboot. If this is happening, reflash cwm in Odin, but uncheck auto reboot. Wait until it says PASS, then unplug and pull the battery.
Next put the battery back in and boot to recovery. (Volume up, home, power. Release power only after it vibrates)
If you are sure you are in cwm though, just flash the modem normally.
Yes im sure its cmw. when I open recovery and look for the zip its nowhere to be found. that's why I was asking if I should change the name.
I did try it by changing the name but the file still doesn't show up.
It's an IMEI problem. If you haven't made a backup of the IMEI folder you can't do anything.

Make sure the sdcard is mounted. Have you tried getting to it on both internal and external cards?

Not true. 90% of unknown baseband and imei problems ive helped people with lately just needed the correct modem. And even if it were the imei, I can still help with that. Im convinced in this case its just the modem though.
Thanks doc... that was the problem...imei and baseband are back. donation has been sent....thanks again.
Hey thanks man! I do appreciate it, but I am just glad I could help! I will definitely put it to good use though! (Broke the lcd on my S3 a while back and haven't had the disposable funds to fix it. Something always comes up...lol!) Will be adding it to my savings for this purpose!
Anyway, since we were slightly on the IMEI topic, there is a backup you should do if you haven't already. (Root is required for this to work though.)
Its super simple and will create an on device backup of your nv data. The backup will be stored on a couple of partitions we never touch, not even with firmware flashes. This essentially makes it a permanent backup. The cool thing about it is every time you reboot, the system checks for any corruption, and if detected, it will automatically restore from this backup. So if it were to ever happen, you probably wouldn't ever even notice it!
Install the Terminal Emulator from the play store. Open and enter this:
su
reboot nvbackup
Thats it! Device will reboot and create your backup. This should prevent you from ever suffering from a lost IMEI!

You can also use qpst to backup imei. Windows app. Free. Lots of walkthroughs around for those less comfortable with cli.

I know, I already have it and have used it and other tools to help fix at least 700-800 S3's, probably more! (No, i do not charge for my help either.) I dont tell about it or give it out unless its absolutely needed for a legitimate imei restore though. Too many people try to use it illegally and Im not willing to take the chance. Its the main reason most of the info has been deleted from everywhere. Only a few threads here and there get by the mods it seems.
Anyway, to my knowledge, no one who has run this backup has ever lost their IMEI. It even seems to help for those occasions after flashing a cm rom where the imei displays "unknown". (Apparently, at least on the T999, cm sometimes has problems reading the nv data. If rebooting several times doesnt solve, stock firmware does).
At this point I believe if you run this backup, you will have no need for a .qcn or .txt file backup, which is why I just dont mention it anymore. And if it does happen, people can pm me and ill be happy to help fix it.
Because of how I understand this backup to function, I do believe if it had been run during first boot, we would've never seen so many imei problems to begin with! I just dont understand why Samsung refuses to do this!
Anyway, that's why I dont mention those tools anymore. If you have any questions about any of it, please feel free to PM me and ill try to explain better.
Hi, Yes you're probably right I shouldn't have messed around without knowing exactly what I'm doing, but any help would be greatly appreciated, I have tried to search for answers on here, but the forum is running so slowly for me at the moment that searches just time out for me.
Anyway, heres what I did - I rooted via ODIN, (CF-Root) and installed CM12.1 - First though, having read about the EFS risks I thought I was covering my ass by downloading EFS Backup from the Play Store - I then backed up my EFS Partition, there were three options, and I assumed the safest option was to leave as default (tar.gz)
So when I saw I'd lost my IMEI after flashing CM, I reinstalled the app, tried to restore - which directed me to an app "Partition back up", which turned its nose up at my tar.gz files! (thanks for that EFS Back up!)
Can anyone tell me what I need to do with the tar.gz files? and do I need all of them?
Thanks in advance.
Partition backup?
Just use the restore options in EFS PRO. What's inside the archive, images or files?
I've just got a file of tar.gz's Radio, CDMA Radio, EFS, and three named M9kefs1 ,2, & 3
I copied them onto my Mac and managed to open them, which gave me .img files too, Which I've tried restoring on the tablet (using Partitions backup app) It reported success but didn't work.
I'll try this EFS Pro, I had seen it mentioned wasn't sure if thats the way to go, thanks!
I've got to ask, why through all of this you didn't use the one tool that would have solved your problem in minutes. TWRP?

To back up EFS you mean? Quite simply I didn't think I needed to, I thought I'd done it with the EFS Back up app

There's nothing better than making a full backup in recovery.
It's your one and all get out clause if your device ever doesn't boot or something goes wrong.
Backup apps rely on a Bootable system.
In fact I would suggest you do it before going any further.
I suppose I wasn't too bothered, as coming from an "empty" tablet with no data loss to worry about, I had in my mind that if all went tits up I could simply flash the stock firmware with Odin. (Which I've now done anyway as EFS Pro wouldn't play ball)
Thanks for you help! Lesson learned on Backups.

Stock Firmware does not flash the EFS partition.
If it gets wiped or corrupted it's gone and not recoverable.
You have been lucky.
Well flashing the stock firmware back cured the problem, Must be a CM12.1 issue. That would explain why restoring the EFS .imgs didn't work either then.
Hi, I have a similiar issue with my SM-T705. I have the stock rom installed. My IMEI number seems to be broken. It's a generic imei 00499 number. However, I still have my box laying around which it came in. Is there any way to restore it from that?

There are dozens of us, DOZENS! Seriously though, if you get a method please share.
QNC Copy of backup of A6020a46 model, Lenovo Vibe 5k plus, needed to repair LOST IMEI & MODEM information.
After updating A6020a46 model with NEW ROW to fix other problems, using QPST program that came with update.
The IMEI numbers and modem information is now missing.
Have tried reset via android program, and hard reset using volume and power, to recovery back to old firmware, no luck in going backwards.
A member of this forum has very kindly offered to help me fix this problem, IF I can find a backup copy.
PLEASE NOTE: My IMEI numbers that are behind the battery on my phone, WILL replace the ones on the backup copy, If they have not been removed.
Thank you for any help.
Hello there,
I'll start from the very beginning...
My old Samsung Galaxy S9+ have a crack on its screen but my phone is insured so I got a new one, I backed up all of the files on the old one using TWRP backup (EFS, DATA, VENDOR, SYTEM, CARRIER, BASEBAND, RECOVERY, ODM). I tried restoring my old data to my new phone, it did the trick but there was a problem, the IMEI is UNKNOWN (00000), I tried scouring EVERY solution I could find to fix the problem but to no avail. Here's the list of every solution I could think of (although I'm sure I did a lot more than that) :
1. ODIN FLASH TO STOCK ROM (G965FXXSBETH2) I USED THE CARRIER ROM (Optus)
2. REPLACE THE DEVICE ID ON THE EFS BACKUP AND RESTORE (USING HEX EDITOR)
3. USE A COMBINATION FIRMWARE
4. REPLACE THE SIM CARD
5. IMEI MAKER/REPAIR
Okay now to explain why all of those didn't work :
1. I flashed it to stock ROM but it still didn't work for some reason, I figured it's probably because the ROM isn't really for refreshing IMEI
EDIT: I tried re-partitioning, pit and Nand erase but it didn't do anything.
2. I tried hex editing the efs backup for TWRP to restore but it still detects it as 00000
3. I can't use a combination firmware because the bootloader is updated (apparently I cannot downgrade) and every time I try flashing it, it just comes up with SW REV check fail (Bootloader) error
4. Well I tried, I though by replacing the SIM card I'll MAGICALLY get my IMEI back.
5. IMEI MAKER/REPAIR didn't do anything, I followed the specific instructions and got my IMEI number into it but when I flashed it via TWRP, my IMEI still remained the same.
Conclusion:
Yes, I learned my lesson and I should ALWAYS backup BEFORE I restore. I need HELP and I'm just in a desperate situation, I've been at this for 3 days now (maybe longer). My foolish self didn't untick EFS, Baseband, Carrier configuration or anything related to cellular phone internet before restoring. Somewhere around me buggering with the settings, my phone thinks it has 2 SIM slots (which it doesn't) but I'm sure that's not the problem. Please help me.
For reference with the IMEI MAKER/REPAIR here's the link to what I used

EDIT: Silly me, of course it won't work because it's for Android One devices ONLY.
Holy ****, never mind that. Thanks for fixing my phone @hainguyenthao you're a legend!
