Hi guys, first thing i need to tell you its about my english, i speak really bad. But please, try to understand me hehehe
I was updating my rom for Galaxy S I9000B, and I forgot to backup my efs folder.. So, I lost my imei.. I was trying to rename nv_data.bak and nv_data.bak.md5 to nv_data.bin and nv_data.bin.md5, but i was looking the date and its the same date (the date same date that i updated my Galaxy), so nothing happens.. my nv_data.bak and nv_data.bak.md5 are corrupted too :/
Im from Brazil, and sorry for my really bad english.. But please, someone can help me?

really thats kinda weird because i flashed 2 roms without having any problems about losing my imei number.
Or maybe i did but i didn't know!

do a search on imei, but i think some people have had their imei restored after flashing stock rom. dont forget to backup efs afterwards, you may have a backup already as some apps back it up (search for efs)

If you don't have back up the solution is to flash a stock rom through odin. This should restore everything. I think you can also flash darky resurrection rom but not 100% on that.

be sure to chown when you are # (superuser) after renaming backup nv_data.bin
you might try it when phone in airplane mode.
your imei is most probably in the backup file
just those dumbasses from xda or darky do not know jack about phones and android how is that ll working. flashing rom will not fix your imei

I've already tried to flash darkys or stocks roms, but nothing happens about the IMEI. I think the problem is that the files nv_data.bak and nv_data.bak.md5 are already corrupted files too so i cant restore my Imei and all the times that i try to flash a stock rom i think the files that my SGS restores are the corrupted files: nv_data.bak / nv_data.bak.md5 / nv_data.bin / nv_data.bin.md5
i really dont know what i have to do but i think that the question is not about to recover my imei. i think the question is about restore my imei, but i really dont know what i have to do, i've tried all..

Flashing a stock ROM will restore a IMEI if the IMEI has not already been corrupted.
I can say this with 100% confidence as I have been in a similar situation. However I did not play with the nv_data.bin file before flashing a stock ROM.
To the OP.
Do a search of the I9000 (SGS) threads for a post about restoring IMEI to nv_data.bin I am sure that a XDA user has posted that they can restore the IMEI number. This may be the only option before returning the handset to Manafacturer for service

I had this problem. Did you install the "sgs unlock"? This is what caused mine to show a bad imei number. I had to take it back to manufacturer and play dumb!

[Q] [Slim Jelly Bean] No Service

Just Installed Slim Jelly Bean.
It's really nice and totally lag-free and I want to keep it but there's no service, I cannot make/receive calls and sms.
I'm sure I'm not the only one being affected by this issue and I suppose there is already a solution but I cannot find it anywhere.

maybe flashing your old modem back , might do it.

Check your imei number by typing *#06#.
If it is changed to something like 0049... your imei is gone.Only easiest fix is flashing 3files+pit rom will fix it

and then re-flash the custom rom back?

hey
first have u tried toggling aeroplane mode??
and if u have gone back to 2.3.6 check if everything is working there and then flash the rom again...Following the steps carefully...

1. flash back to stock with odin.
2. Notice how gingerbread had re created the imei.
3. Backup /efs
4. Go back to custom ROM
5. Only restore efs if needed.
Sent from my GT-I9000 using xda app-developers app

I used this http://forum.xda-developers.com/showthread.php?t=1308546 for backing up efs
But now the program no longer runs, it does not recognize the phone with Jelly Bean
Any other methods of restoring efs with the img the program created?
EDIT:
Alright, restored back to Gingerbeard,
Used Nitrality, ES File Explorer Manager and backed up /efs folder
Re-flashed Slim ROM again and went to ClockworkMods recovery file manager, deleted the efs folder and copied the efs folder I had backed up,
Rebooted the phone and nothing changed, the result is the same, could it be that the rom does not support my country (Greece)?

bamp , sorry i really need a solution...

I had the same issue with SlimBean. My solution was to restore DarkyROM Ressurection with repartition via Odin, then flash CM9, then SlimBean.
Everything was working good after these steps.
Sent from my GT-I9000 using xda premium

was this ever resolved? i had a similar situation after trying some early-early JBs. I tried several ways to restore /efs and none stuck across a reboot.
Also: when flashing any other rom or zipped kernel, did your installation abort? Absolutely anything hangs up on a /tmp/updater.sh, if I'm using CWM 3.* or 5.* I did manage to flash the latest Semaphore JB kernel by Heimdall; wiped everything and restore that nandroid, but then I was in a succession of reboots straight to recovery. Even on different kernels -- Devil3 with /datadata or back to Sema 2.7.4 to get back to stock or flash from there to THS CM9 nightly.
I'd guess these things are related, for me, or I just wrecked a whole lot and good.

Why cant I get this to work :-/

2) when did you flash the slim bean?
Solution:- Reason is you had Jumped from GB to JB (should be on ICS before JB), so now you need to
1) Download Root Explorer from Play Store and use it to
2) Search your internal SD card for sdcard/backup/efs
3) Copy nv_data.bin, nv_data.bin.md5 and nv.log paste them into /efs in your Phone memory
4) Reboot to get back your original IMEI
or
you can start from the beginning.. go back to GB 2.36 (use a JVU ROM + Root, upgrade to ICS CM 9 and than to CM10

ok so when I pasted the 2 data file into /efs on the phone memory I noticed there was already 2 in there so when I pasted it pasted them at nv_data-Copy.bin and nv_data.bin-Copy.md5. When I did *#06# my IMEI number is still blank?
Should I just do your second option, start from the beginning?
If thats the case im not sure where to get the right ROM + root from? Im really sorry if I am frustrating you :-/.

Nope, you need to overwrite those files, meaning delete the ones inside and paste the ones from the backup.

I had this problem and ended up getting a replacement from Samsung.
If you are saying that you've got a blank/unknown IMEI in your phone settings and also when you dial *#06# then your EFS partition is probably corrupted. Your network will probably not let you make phone calls if this is the case.
I don't suppose by any chance you done the firmware "Full backup with CWM to ODIN format" as per the instructions in the sticky thread on this forum? If you did then try flashing that because it contains a backup of your bml15 / efs partition and you will also get your previous firmware back.
If not then with then I would say prepare the phone for a return to Samsung.

Mine says zero, I'm not sure that flashing from recovery affects the binary counter, may just be download mode / ODIN.
By the way it may be worth trying to restore your CWM backup, especially if its the stock firmware because you'll need to anyway. Severely doubt it will work to be honest, but you never know.

Samsung may check to make sure you have stock ROM, stock kernel, your phone is not rooted and your binary counter = 0. Act on that information in whatever way you deem appropriate.

To be honest I don't know enough about the bml15 / EFS partition and how exactly it generally gets corrupted to be able to answer that but I lost my IMEI without flashing anything.

Flash stock ROM (odexed, not deodexed), UNROOT, and reset binary counter. Flashing and resetting through Odin 1.8x, unrooting through CWM, not stock recovery.
I thought it was described in (one of) the sticky threads.
Oh, and don't forget to remove your SIM and SD card !!!!
P.S.: Your IMEI is still under the battery.

No i don't think it is possible...every phone will have its own IMEI number...

yes and changing the imei is illegal

Take a look at Post #3 on this thread "Originally Posted by Doky73", it describes how to restore your lost IMEI number!!
http://forum.xda-developers.com/showthread.php?t=1781191
Doky73 is the creator of the Galaxy Toolbox app so I would take an educated guess that he knows what he is talking about!
I would think that this would work on an S5830i because Galaxy Toolbox works and I can confirm that I have found my IMEI number at offset 0x80000 of the bml15.img.SAVE file.
Do this at your own risk obviously, I am only passing on information. As to what the technical legalities of it are I don't know quite frankly but obviously all you are doing here is restoring the phone's authentic IMEI number as opposed to changing it for a fake one.
Hope this helps those concerned!

Very useful to people who just corrupt their efs partition

[Q] Bought Unlocked Galaxy Ace EFS Folder

Hi, I bought an unlocked galaxy ace S5830M a few months ago, and I rooted it as well so I can install a new ROM. I've read that I need to back up my EFS folder, but I found out it's empty. Is that normal? Do I need to backup anything at all if the phone came factory unlocked? I've looked for the answers, but couldn't find anything either here or on google that could tell me it was safe to install a new ROM. Any help would be greatly appreciated!

[Q] IMEI Recovery

Hi guys , i'm about to buy a N7000 .
The seller told me , it has no IMEI due to bad flashing .
Is it anyway to restore the original IMEI?
Thanks you all.

Maybe.
I own a phone like this myself. (Bought it to replace the cracked screen on mine. Now it has the cracked screen, but working fine for the most part.)
It depends, on the condition of the efs folder. It could be that you could recover it, but maybe not.
Also look in the Galaxy S2 forum, most of whats there applies here too.

I wouldn't bought it in your case, without EFS you won't be able to use it as a phone. IMEI modification is also illegal in almost all countries, FYI.
BTW, use the Q&A section for your next questions

If we were talking about changing the imei you would be correct.
However, the phones imei is written under the battery, and recovering that would be fully legal in most if not all places.

Well, until we know more about the condition of the efs, I can not recommend buying the phone.

I had the same problem with a friends Note. If the EFS file is deleted and no backup is kept of the nv_data.bin file then you re pretty much screwed. MediaTek cpu phones have a mode called Engineering mode which lets you change your IMEI to whatever you like but i dont know if this applies to other phones as well. If you have the phone, download UncleTools app from PlayStore to test this. There are some guides about this if you search for recovering IMEI from engineering mode.

Yes, there is. The imei is in efs folder. I could send You my files if You get the phone, just PM for it.

It depends on whether the folder was deleted or just the firmware is wrong (branded).
I've repaired my old S2 once by copying my brothers IMEI folder and it fixed the phone.
