You need to ask your friend if he ever made a nandroid back up and still has the file.

nope he said he dont have anything.. like a backup or anything like that
Without a Android backup or a efs backup then you are screwed. Sorry bro, efs is the file that contains your phones identity, without it your phone is typically "not alive". You can still use it like iPod, or you can salvage the parts and sell them.

what about restoring the corrupted imei with a jtag or z3x box?
my friend gave me a phone. when i check it it has no IMEI, no Baseband
so i search in this forum and tried many tricks to recover IMEI but no luck.
i heard that if i can flash a dummy IMEI to this phone i can repair it with z3x box or octopus Box
the problem is i don't know how to flash this to dummy IMEI and also i don't have flash file for it.
I beg everyone to help me. or can give me link where to download those flash files.
or how can i put dummy IMEI to this phone.
i heard nandroid can fix this but i dont have those nandroid.
im new in this forum and sorry for my bad english. help me guys.

up
still no solution
i need help from the experts
you have to take the phone to the samsung service center and get it repaired because your efs folder is missing which has the imei number
With a phone root and busybox
Galaxy unlocker > https://play.google.com/store/apps/details?id=com.helroz.galaxysunlock&hl=fr
Trying to see if you can recover EFS
i tried those you've mention but no luck, i wanna try to restore a nandroid backup but i don't know where can i get or is there will be someone to lend me his nandroid back. sorry for my bad english

there is NO IMEI because your efs folder is corrupted or missing/doesnt exist/got deleted,etc..so here are the things you need to follow
* Root your phone first using this link.
http://forum.xda-developers.com/showthread.php?t=1894737
*Flash a custom recovery (ClockworkMod Recovery/CWM)
so now you have a custom recovery so now you can take a backup and you should take a backup(for precautionary measures).
*Install the app "Galaxy_S Unlock" from playstore as LoLaTion said and if you cant download it from playstore then download the apk(installation)file which you will get easily on web.
Also install BusyBox which is available on both playstore and web.
*Now by using the application "Galaxy_S Unlock" try to recover your IMEI.
and if still there is no luck on your phone then you can just go to Samsung Service Centre and hopefully they will solve this problem for you.:angel:
Phone=rooted
flash cwm for backup
installed busy box
tried to repair using galaxy s unlock
but no luck, service centre said they can change board but it cost 70-80% of the brandnew
i can still see my efs folder
.nv_core.bak
.nv_core.bak.md5
.nv_data.bak
.nv_data.bak.md5
was dated 10/12/2012
and my friend said this phone was damage in november
i think there is still a way to fix this rather than go to service centre cause i still don't have budget to buy new board

do you get any error message like
Warning! A problem was detected with your device. Your device IMEI number is invalid. And invalid IMEI number could cause network issues including the inability to call emergency numbers.
then this link might help you http://android.stackexchange.com/questions/28963/how-to-restore-my-imei
however,while browsing our forums I came across this http://forum.xda-developers.com/showthread.php?t=1308546
but you cannot use it because its not for our phone... wish we could had something like that.. and just asking out of curosity does your phone have a IMEI number under the battery?

you said you can see your efs folder... try this http://android.stackexchange.com/questions/28963/how-to-restore-my-imei
since you can see your efs maybe somehow on CM9 or CM10 there is a possibility that your IMEI can be restored.. give it a try
GoodLuck
hey all, I've got an S2 in at the moment that has lost its important EFS data. Flashed it with odin with the re-partition ticked (I believe) and don't hae a backup.

Cheers buddy got my s3 running sweet now running kit kat4.4.4 but I'm sure there is a better rom I can Install .... hmmm
I am glad your problem was solved, always back up your efs files cause even sometimes you could lose them when flashing a rom, it once happened to me. Anyways try CM if you want a good rom.
Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?
Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys
OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav
1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks
Mav
Been searching for ages can anyone please point me in the right direction for a fast download of stock o2 5.1 rom? I believe I may need this one G920F_O2U_G920FXXU2BOGC_G920FTEF2BOG1.zip at the moment rapid gator is going to take 10 hours lol.
Thanks
BTW is anyone out there on the s6 forums hardly getting any help really want to try and sort this thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

Thanks silly question but how do I know if my efs is ok or corrupted?
at the moment the phone works perfect it is rooted, twrp recovery and vador rom but it just wont connect to networks. I know its not stolen or lost.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.
---------- Post added at 08:46 AM ---------- Previous post was at 08:37 AM ----------
Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.
