I believe that my problem will be solved by experts :angel: I would also like to mention that i am too unable to use earphones and camera in my phone.......please help me.....
Thank you!!!
Hi
Thanks for writing to us at XDA Assist. It sounds to me like you have a corrupt EFS partition. I'm guessing you have zero service on the phone? Did you ever make an EFS backup? If not, you could have a paperweight on your hands unfortunately.
No response in two days, thread closed, thanks.

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

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
Hi, i have a problem, i recently rooted my phone and applied a custom recovery "CWM" at first the device was OK, but suddenly the imei and the baseband got lost after rebooting a few times. I haven't apply any custom roms yet. I tried factory reset but was a failure and it didnt restore my baseband and imei. I have attached the image that shows no baseband and imei.
I have read on the internet on EFS backup and restore but I don't have EFS backup as i didnt flashed any roms yet so i didnt made any backup of the current rom.
Now here is the biggest problem of them all. I find solutions on the internet that are usually for galaxy devices and not for the deice i have.
Myphone is "Gfive g7 (MTK6589).
I download a stock rom from the internet its for the same phone but its processor is marks as mtk6582. Can i try to flash that rom on the device, or will that lead to bigger issues as the processor marked is different.
I also have another phone that is also MTK6589, can i make back up of its EFS and restore on the other phone.
I just found out these MTK phones doesnot support EFS. So Kindly help me, i will be grateful
Similarly can i make complete backup of that phone and restore it on the other phone?
And any suggestion else than that, how can i fix my phone IMEI and baseband.
Any help.... i will be grateful..
Regards

Dear S6 Edge users
I was trying to install a new ROM on my samsung galaxy edge s6 (SCV31 g925j). And i wiped everything in TWRP before installing it. it seems liek i have wiped EFS with IMEI too. :silly:
Now, i have another device, so i took a backup of EFS in twrp and tried to resore it. However, my IMEI is still null.
Flashing stock ROM did not help too.
Could anyone please let me know if i can restore EFS/IMEI somehow? Can i copy it from my other device that actually works?
Many thanks

Technically you can restore efs backup from another phone.
Would it work without any problems, that is another question, but I honestly doubt it.
You could (if out of warranty) take phone to a 3rd party repair shop for fixing IMEI with Z3x box, or similar device, but some other issues (network, SIM, as in my case) could arise, not necessery, but could happen.

Thanks for reply. I guess i will have to try as many repair methods as possible (using root) and see if it helps.
If you manage to fix it without a box, please keep us posted, me and I belive lots of others would like to rebuild/repair efs.
Myself included
