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
I m using samsung GtS5302, I tried to customize my phone by flashing it to CM9. But process strucked in between, luckily i have a backup of my original rom which i restored but i have lost my imei in all this process, an error (IMEI null) is shown to me when i checked my imei ..how can i recover that... 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.

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.

Hello every one pls I need help and advice from experts in the house about an issue.
Is it possible to restore the userdata backup from one android on Nougat 7 to another different android on android pie 9?
My former phone (Tecno WX3P) is dead and not coming up. I can't fix it until I test if the emmc is still working because I currently don't have the tools. to do it.
I have 2 full backups of the phone ( userdata.ext4.win for twrp and userdata.bin for miracle box) which I did with twrp recovery and miracle box. But now my issue is I need to restore the app data of my apps to another phone I just got (Itel P15) so as for the apps I was using on my dead phone can comeback to their original state at the time of doing the backup. I want to restore the userdata backup because of the information I have on Apps like Whatsapp, Notepad and some other apps. The Whatsapp is a Whatsapp mod (FMWhatsapp) so I don't have a google drive/offline backup of my chats.
If it cannot work, and there's another way I can do it, someone should pls help me with it. Thanks.
