Have you checked into you internal sdcard if you have a backup? Some custom roms create a efs backup into /mnt/sdcard/backup, when installing them.

Need to know what is your phone model . Check Here to chose your forum/Guide by Version of your phone or you will have more problems by using wrong solutions due to different versions of Galaxy S
use this guide
you can get a rescue kit from My Android Collections and or a solution from My Android Solutions
Use only ROM and solution for your model and Wipe x3
But First powerdown, pull out Battery, SIM CARD, and EXT.SD card, press power button for a minute, than powerup without SIM and Ext.SD Card....
(Do remember to backup your contacts, data, images etc and also your EFS folder before flashing a ROM and make sure you have more than 50% battery charge before you attempt any sort of flashing.)

Insert SIM / no IMEI / baseband unknown after official JB update

hello...after the update from GB to the russian JB ROM i have these problems: insert SIM,my IMEI is missing and baseband unknown...i have followed the exact tutorial..i have had galaxy ace before so i'm not a total stranger to flashing thru odin...i have tried wipe data , wipe cache, factory reset, rooting and deleting dalvik cache and nothing...i reflashed back to GB..worked fine but with the same problems...everything is working fine , wireless and bluetooth...i can boot into recovery mode and downloading mode with no problems...i have read some things about the EFS folder...i didnt do a backup of it...any advice?

If the imei is missing, you destroyed the device. You can try to get it back. There are a few guides. Or you can get it serviced..

I used this.

only one working solution
You can install jb root it and reset binary counter. Then flash stock gb. Find method in development threads. And den get it serviced. They will replace the motherboard. Hope you have warranty. Else it's 6k for the service. I got the same problem and followed this procedure.

Hi all, Does anyone could fix the imei issue? A friend suddenly appeared no signal and does not recognize the simcard, I checked the IMEI and I get null, I check the baseband and gives me unknown ... You have EFS folder backup previous ... :crying: Please help ...

do you have your old imei anywhere? like written down or as a backup file? there are apps for imei backup and restore in the play store... if you dont have a backup of your original imei i don't thinm there is any way of recovering it.
Gesendet von meinem GT-I9070P

If you don't have backups you can't recover it, you will need a service box or send back to samsung, but that's risky, because that's not covered by the warranty.
Which files/folders have you copied exactly ?

I've overwritten entire EFS partition thru dd.
I do not had backup and the partition was already corrupted.
Sent from my GT-I9070 using xda app-developers app

The original imei should be available on the box in which the phone is shipped. Search it. Then you will have to dd the efs partition as an image file and edit the imei in it using hex.
It's difficult, but your original imei can be recovered!
I do not respond to tech support via PM

I tried it on my phone (ace 2 - same novathor chipset) but after I flashed a new efs my imei still was the same.
Are you sure you didn't changed anything else ?
Also you can try this: *#197328640# in dialer, and search for "NV Restore" or "NV Rebuild" option (for me it's under "Common") I'm not sure how it works, but maybe the phone has some backups on a different partition.

I've tried to delete every file on /efs but cloned IMEI remains.
I think that IMEI is stored or cached anywhere else.
I already tried that option (NV Restore).

Modemfs also contains some files from the EFS partitions RFHAL.DEF/RFHAL folder.
Have you flashed a JB or any firmware with repartition ?
I noticed from a log file in /efs/pre_recovery.log, when the device is repartitioned there is an additional check if the imei is valid or requires a restore.

Exactly, my 3G stopped working after downgrade using Philippines ROM and I tried check repartition.
My 3G started to work after I copied modemfs partition from my friend device.
Do you know how to recover from that?
Sent from my GT-I9070 using xda app-developers app

Well if you don't have backups it's difficult because I can't even tell where the phone stores the imei, or how does it work.
Of course it's possible to reverse encryption and edit the files from your friends phone but it's VERY difficult.
It's clearly uses a different method, because there is no nv_data.bin (on other Samsung devices the imei/simlock/product code are stored in this file).
If I find anything I'll let you know.
The cheapest sollution is offered by this guy: http://forum.samdroid.net/f70/repair-imei-s2-5729/
Or a very risky sollution: Brick the device and send back to the repair center if it's still under warranty.
Edit: Try flashing that rom again with repartition and see what happens, also check the efs/pre_recovery.log, for me says "valid IMEI & skip restore" so obviously there are at least 2 places for the imei, that's why for me doesn't changes even if I wipe the efs.

I've lost the imei some months ago and i've solved flashing the italian GB firmware, but you can also use another firmware.
Inviato dal mio GT-I9070 con Tapatalk 2

You probably flashed a wrong modem, but basically you didn't lost your IMEI, just the modem part wasn't for your device and it couldn't get the info.
This usually happens when you flash a firmware from different region, for example i9070L rom on i9070 device.

There's no way to regenerate/restore the modem part?

I wrote this to giagia96.
In your case I don't know why the phone "decided" to change the imei.

[Q] IMEI NULL/NULL Baseband UNKNOWN

My brother owns an AT&T cappy...n after some months of custom rom flashing, he gave me the phone asking me to repair it.
It has stopped reading the sim card, when i checked the imei of the device it gave me a popup of IMEI null/null..also the baseband version is also unknown..
I have many a times flashed the stock rom as every thread about my problem is telling me to do..
also used galaxy s unlock, app for factory unlocking GS devices..but know success
i seriously want to give it a last try before handing it over for a repair outside..
any help would be highly appreciated!!!!!:crying:

Yep, usually using Odin or Heimdall to return to stock firmware should restore the imei. Have u tried to flash to Stock KK4 firmware yet ? The Odin or Heimdall One Clicks for i897ucKK4 can be found here... http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3.

yess!! many a times..but no success

I also wanted to add that :-
during the galaxy s unlock method..i usually get the busybox problem error...though i've installed and verified it many a times

With all the months of flashing that ur brother did...i would think there would be a backup of the efs folder on the sdcard?? Some roms and kernels, when flashed, will create the efs backup for u.

yess!! hopefully dere's an EFS folder.. but i was too bugged up when googling for the method for restoring it..
n also i'm not sure whether the folder is fine or corrupted/messed up..
also i'll be greatful if i'll get to know the easiest step by step process of restoring it.:good:

If you check on the internal sd, you'll see an efs folder. Should probably take a look for yourself before asking those questions

[Q] internal storage faulty or partition corrupt

hi guys,
i just received a s3 mini which seems to have massive problems related to either it's storage drive or partition.
the phone is entirely stock. it's showing some developer overlay screen with yellow text.
when i check in system settings for storage, it's showing me 0.00b total space and 143mb applications.
when plugging it into the computer, the phone will show up as a drive but the size is messed up, too. it's showing -15827131273 bytes space.
when i reboot the phone i think it's kinda discarding all changes. I flashed twrp with odin. flashing suceeded after rebooting and trying to access recovery, twrp was not available but the standard recovery.
check attachments
so what can be done to fix the problem?

the phone was pretty much stock everything. the owner does not have any technical knowledge of rooting, modding or bricking the phone. he said from one day to another, all data was just gone and the phone could not been used because it's pretending to have no space anymore.
flashing with odin seems fine, but partition / other things do still mess up everything like before. is it an issue thinking modem and baseband being unknown / corrupted etc? is there a way to get them seperately to flash them ?

I think modemfs or EFS is/are corrupted. If you go to settings > about phone > status does your phone show your IMEI, serial number etc. as NULL? if not then is your EFS not corrupted (or type *#06# for checking your IMEI number )
