[Q] QUESTION: I9000b - How to recover the IMEI file galaxys-efsbackup.zip? - Galaxy S I9000 Q&A, Help & Troubleshooting

Dears,
I have I9000b and somehow I have made a backup of my IMEI and I donĀ“t know how to use this backup to restore it.
I said "somehow" because I forgot how I did this backup.
I have flashed my phone with a ICS version (underground-B-II), after this flash the IMEI went to that famous one ending in "4000".
When I go back to the old version (Gingerbreak 2.3.4) the IMEI is back to normal, so I can make the backup when needed.
The backup I made has generated a file named "galaxys-efsbackup.zip".
My question is, how can I flash or in some other way use this file to recover my IMEI?
Thanks,
Thiago Neto

EFS backup

Hello,
there is nothing wrong with my phone, but this is only a question.
my phone was on froyo 2.2 ( official KIES - Xen version )
Did a ROOT, and made a EFS folder backup with Root explorer.
Afther that, i went to darky 7.X. and now i am on darky 8.0. no i am on darky 8.0 i made a EFS backup with this guide: http://www.galaxyroot.com/how-to-efs-folder-backup-restore-nv_data-bin/
Is there any difference between the backups of my EFS folder? i mean, is there any difference between Eclair (2.1) Froyo 2.2 of now the new 2.2.1 rom? Need i to make a new backup of my EFS folder? or is the old one good?

sorry
Were you able to backup your efs partition?
If you were able to backup your efs before the unlock, you may push the files back to your tab and check if that would restore the missing imei.
Or you could reflash your tab with a stock rom and see if that would restore the missing details.
On my Tab it is on the backside below the barcode...

Missing baseband means no modem. Flash one through odin.

(Q) Changes of IMEI from Darkys 2.3.3 to MIUI 2.3.4

Good day to all expert
I upgrade my sgs i9000 from darkys 2.3.3 to miui 2.3.4, i noticed IMEI changes from original 053xxxxxxxx to 0409xxxxxxxx so i decided to flash back to darkys 2.3.3 and IMEI returned to its original configuration. Is there any way to fix this issue or I did a wrong procedure in flashing rom.
Please advice
Thanks in advance
could try backing up your EFS folder to your SD card before upgrading and then restoring the back up once your on miui?
what happend when your IMEI number changed?
Try this to backup your EFS before flashing:

[Q] EFS back up Imei related (noob)

Hi Everyone, Hope ya'll are good?
Sorry I am a total noob at this so please go easy on me
Thanks
I rooted my Samsung galaxy S GT i9000 thats all good and updated the software from 2.1 to 2.3.6 (yeah)
Then re rooted it again - Not happy CMW was on there I am scared of that after people saying it BRICKS thier phone
Issues that need help:
1. The EFS Pro tool does not work? I downloaded a few versions all of them just say connect USB???
the only one that was ok was the early v1.4 BUT that kept crashing and saying EFS failed.
just a few times EFS was OK then it crashes???
2. I backed up VIA Titanium backup all my phone and a separate efs folder on my phone and PC.
Will this be ok as EFS back up of the IMEI? or do I need to do something else?
Target = I want CM10 Jelly bean 4.1.2 on my phone.
3. What do i do now get Goomanager or Rom Toolbox Pro or Rom manager?
Which one is best?
4. Do I flash a new rom? or flash the existing one?
5. Can anyone help me please?
Thank You
If all goes well I am willing to buy Coffee for them... If that is okay and is not offensive
Sorry if it is

1. Never heard of the app.
2. Titanium Backup is fine, I would recommend to do a 2nd backup using Nitrality - it's an app. Also backup your backup folders on your PC.
2.1. If you want Jelly Bean, I'd recommend Mackay ROM. The upgrade process from GB to JB in general is quite tricky, even though not risky if you do everything right.
2.1.1. First of all backup your IMEI as mentioned above.
2.1.2. Flash CM9 twice via CWM (first flash will give you a boot loop, don't worry then)
2.1.3. Flash CM10 via CWM (don't remember if you have to do it twice, you'll see if you run into boot loops )
2.1.4. Flash whatever ROM you want.
3. Why do you want any of those? As I already said, you can flash everything via CWM.
4. What?
5. Yes

[Q] Downgrade from JB 4.3 to stock 4.1.2 - IMEI error with EFS backup

Hey guys! Need some help here.
I know there are other threads on this forum about this but I've tried everything suggested to recover my IMEI but nothing works.
The problem is that I updated my Galaxy S3 to a custom rom with android 4.3 jelly bean, everything was okay, after that I decided to downgrade to the stock android 4.1.2 and my IMEI was not recognized any more, I must emphasize that before update from 4.1.2 to android 4.3, I did a backup of the EFS folder.
I restored the EFS folder with the 9 Steps to recover your imei guide on my new installed android 4.1.2 and I still got a wrong IMEI 0049... and Serial 00000... I have followed the guide lots of times and it stills the same.
I had read that it could be a modem MG6 problem in this post ... but now I'm with with stock 4.1.2 so that's discarded.
I also notice that it seems that the android os rewrites the nv_data.bin that I have previously copied into the EFS folder, is this possible?
Because in theory it should work:
I have a backup of the EFS folder got when I was 4.1.2.
I went back to Stock JB 4.1.2 rom.
I replaced the EFS folder with the "9 Steps to recover your imei", and it continues with the 0049 ...
Technical service want to charge $ 180 to restore it but it does not seem right for me when I have the backup and I could solve it.
Guys please some help!
Dude do you have a Nandroid backup from a previous rom? If yes restore it and you should recover your imei back, then retry to flash the new rom again. It worked for me!

Why would Nandroid restore IMEI if it has never backed up the EFS ???

It depends which recovery you use!

I am aware that Philz lets you create a EFS backup on its own .
So pray tell the recovery that automatically backs up EFS in a Nandroid as it should be stickied in the faqs

Hey thanks for the response but that's another rare point, I have noticed that in other posts, and also you say, that there is a /data/radio folder but I don't have the radio folder, the only radio folder I found is /data/misc/radio but inside this one there isn't any NV file.

Successful Downgrade to stock 4.1.2 from 4.3
I had similar issue upgraded to UK Stock 4.3 from Samfirmware ad had a terrible experience. I came across this 4.1.2 stock rom for Germany that worked with no issues as this one has MG4 modem that reads EFS2 partition newly implemented by Samsung,
Product Code: MBC
PDA: I9300XXEMG4
CSC: I9300MBCEMH1
MODEM: I9300XXEMG4
simply flash it through ODIN
http://www.hotfile.com/dl/250954845/08fe425/I9300XXEMG4_I9300MBCEMH1_MBC.zip.html
If your S3 doesn't reboot on its own, enter Recovery Mode by pressing Volume Up + Power + Home button simultaneously and then performing a Data Wipe/Factory Reset and wipe any cache partition. Then select Reboot System Now and you should be good to go.
Hope your problem will also solved as mine. Click Thanks if it works
I managed to get mine back by going back to 4.3, thought i had bricked my phone. I then went to a newer 4.1.2 as above
How to know that backing up ime by efs error? I backed up my ime. I am afraid of it's error. Because i never try jb4.3. So i never check my backup my ime too. I attend try cm11. So can i downgrade from 4.4 to stock 4.1.2 without lost ime?

It's seems like that the ROM you posted is for i9300 and not for i9305 ..
And I also like to know if I'll get any problems after downgrading from CM 11 ?

Just check the modem version used by the ROM you have used. if it is equal or greater than MG4, then my solution is hoped to work. I believe that older modem version do not modify the EFS structure therefore no worries for old ones.

Made an account on here just to confirm that this method works. I downloaded the file which contained a single .tar, flashed via Odin but came to a boot loop. So cache partition wipe and factory reset brought me back to 4.1.2 and the IMEI is all good so I can connect to my mobile network fine. Thanks for that buddy, you're awesome
