Deleted IMEI (NO BACKUPS) - Galaxy S II Q&A, Help & Troubleshooting

Hi guys, hopefully you can help me here as I'm at my wits end. I've tried everything I can think off and can't fix this blasted phone.
To be honest I have no idea how all of a sudden I lost my nv_data.bin and IMEI as first my phone wouldn't boot because of an error with the /efs folder.
After numerous searches online I managed to finally get it working by using odin and flashing CM9 for the Galaxy S2, I tried others and none of them worked. From here I used tools like GSII Repair and Ktool and was able to create a nv_data.bin but IMEI still gone but at least I'm back to having a baseband.
My issue is now that I can't restore my IMEI number any backups or nv_data.bin or.baks where gone, I tried all the tricks online to restore and nothing.
I have the generic IMEI "004999010640000" and of course can't connect to mobile network.
Is there anyway that I can manually add in the IMEI number to fix this issue??
Thanks in advance.

I haven't read to much into it, but the below might help.

I'm sure there has to be a way, what will the service centre do that I wouldn't be able to??

They may have better tools than we do.
You could try flashing the ROM the device came with.
I too have this issue with a friend's phone (as some dumb ass tech guy flashed a branded firmware without backing up EFS) , so I have to flash any ROM I can get my hands on without the certainty that it would actually work.
Some guys did report that it worked.

Sadly I've done all of that, apart from smashing the phone off the ground lol

I'll give you a tenner for it if you do that.

Yeah, it's not the device's fault but yours.

you need special hardware to recreate the efs folder and rewrite the imei.. changing the imei is illegal on most countries so its obvious that it wont be easy to change... the service center has the tools to recreate the efs folder... flashing software will not fix the corrupted efs and would probably make it even worse...
our methods for flashing:
computer ----> phone
specialists and service center:
computer ----> "special hardware" ----> phone
you can do a search on the internet on what "special hardware" they use but i doubt that that would be for sale in a country where changing imei is illegal
software alone cannot recreate the efs folder nor write a new imei.. all you can do without the hardware is try to recover your corrupted efs if still possible.. if it comes to the point that it needs to be recreated or rewritten then it would be impossible without the said hardware

EFS Restore Doesn't work [SGS II Bricked] (Solved)

After i attempted to restore efs_backups made by dorimanx kernel i was shown that my phone still didn't get any signal at all
i mean the EFS restore option didn't work i tried repair/restore/format any option EFS Pro can possibly give me and still no luck.
and when it did brick i didn't flash anything i only used the phone normally.
however i noticed that my phone always resets every efs to latest even if i restore/format it is being changed, as my files always say 10th NOV/12th which it shouldn't be as i restored the IMEI even tried to do so manually, what could possibly be the problem?
Yet i see i restored my serial number (before it was only 000000)
but i still have that FAKE IMEI which still doesn't want to be gone after i tried to restore manually/EFS PRO
any ideas?
Ok i have now fixed my phone if any moderator could just close or delete the thread.

Sorry i don't know what i exactly did but i knew i toyed around with efs pro, repairing restoring etc.
after one day i tested my sim it just worked, but it didn't the same evening as i toyed around

No sim, emei, efs...Any software repair shop?

Dear Forum,
Is there any repairshop that could fix this problem?
Problem: no sim working
efs folder is empty
shows no baseband
shows no emei
History: I bought this phone as a defect with a cracked screen so I fixed that. And then I found out it was software faulty.
Anyone?
Thank you,
Happybeat
why not ask in the correct section?

I don't know if this will work but it's worth a try.
Open kies.
On the Taskbar select tools and then firmware upgrade and initialisation.
Enter the model name in caps. Ie GT-I9300 and hit ok.
Then enter the serial number written under the battery.
Then do as it says on the pc screen and put your phone in download mode.
Then Flash.
This will restore the phone to compete stock region included this might fix the issue.

So, after some intens reading and trying it doesn't work. There is no backup left on the phone and it looks completely clean. In phone explorer it says the system maps are empty. So the maps are there but no files or backups.
Any other solution?

No EFS backup IMEI not restored after a stock firmware flash .

Stuck at boot animation + more info inside

Hello, so I ran out of battery on my way home, when I got home I plugged the phone and went to sleep. Today when I woke up, I turned on the device, but it got stuck @ galaxy s3 boot animation, the animation you get before your ROM's boot animation kicks in, so I went to recovery and tried to recover one of my recoveries. it didn't help. I did a factory reset, it still was the same, stuck on galaxys3 boot animation. So I decided to flash stock samsung rom using ODIN. But now I'm stuck at the samsungs stock ROM boot animation, I tried factory reset couple of times but it didn't help.
Any idea what might be the issue, I have flashed this rom
Edit: Also the line "E: failed to mount /efs" is something to worry about when you boot into recovery?
So flashing via Odin works w/o errors?

Yeah, when i flashed using odin, I didn't encounter any error, more one thing to mention, when I boot to recover I get
E: failed to mount /efs
Is that something to have concern about?
oh yes. do you have an efs backup? that's the first thing you should do before flashing anything. if yes, restore it. if not, send it to service

Yes you will find that the vendor or Samsung refuse warranty .

You are kidding me, so basically if I didn't root my device, vendor/samsung wouldn't had a choice but to replace my device, but because of I did root my device, vendor/samsung will refuse to replace my device, am I correct?
Is there any other way to unbrick my device?

you are correct, in the EU you still can get lucky due to some regulations and you have to show that the root did not cause the problem, outside the EU I am not sure. The restriction of the internals of every device is not for nothing in place don't you think so? Otherwise manufacturers would get hundreds of complains because someone messed up something...

Hey, I just came back from my vendor, they say they can't fix it. Can I some how restore EFS? I have the Phones IMIE/S/N written, on the back of the phone, can I make a new efs folder/files? using this DATA?
Thank you!
EDIT: If I'll have to ship to samsung, do I have to talk with them first? or just find their ARMA address and ship there?

If you do not have an EFS backup I guess it will be difficult to restore. Only solution then will be to send it in for service if I am not wrong.

You are correct, it would be difficult to restore, or there is another option, make my cellphone not boot at all, so the vendor won't be able to check flash counter.. in that case the vendor won't have a choice but to replace the device.. got any suggestion how to brick your device so it won't boot at all? disconnect the cable while flashing?

so this is just backin up the 2 efs partitions, modemst1 and modemst2? but in app form instead of my script?
the efs backup function has also been added to TWRP.
this could be useful until TWRP is working for the D802 international variant.

you should probably create a new thread and get help for this. Like the link in the OP said, efs folder are unique to each device because it also contain imei/esn number. Using someone else back up wont help you with your phone. maybe theres a different fix.

We could if we had something that would allow these files to be converted to a format that is readable by a hex editor, and then convert them back. I have been trying to find something like this for a while but I can't find anything. If anyone knows and would be willing to share, I am sure a great many of us would appreciate it!
Tks @hoangnova :good:
This is my last ditch effort. Small back story: I somehow wiped EVERYTHING on my G2. EFS partition, ESN, data, SIM info., everything with dialer codes. All of my network information reads "unknown". I tried many methods from here on the forums to get this data back and it turns out I have lost my EFS partition- DNA for the network? I sent it to LG to get it fixed, having done a hard reset and leaving no trace of root. They sent it back without even asking and did no repairs. The note said "board bent". WTF?? How does the user bend the main board, especially when I never opened it? They voided my warranty and ripped off my IMEI/MEID sticker from the back of the phone.
Anyways, I am here with a brick. No network still. Here is what I have done:
1) .tot method to ZVC. Several more times... once to ZV7 where I lost touch capability. Luckily saved my arse with a micro->usb cable and a mouse.
2) attempted to root with ioroot25. Failed because the phone WILL NOT find recovery mode. adb, voldown+pwr then again from power off, and apps are unable to force the phone into recovery mode. I assume it is possible that my recovery mode is deleted?
3) Would have tried all of these "rewrite your efs/imei/etc" things but I can't do any without root. Can't root without recovery, can I?
4) Spent the last two weeks scouring the internet for a fix and going back to my Epic 4G temporarily.
Please help me, has anyone seen this before? Can anyone help me fix it? I am to the point where I would pay to have it fixed. Any experts out there? XDA has yet to let me down... I just need to know if I can fix it or if it is a brick so I can go searching for an old Sprint GS3.
Thanks all,

[Q] Lost IMEI number on I9505

A friend of mine went aboard and had his SGS4(I9505) unlocked. He came back a few days ago and yesterday he came and the phone was not able to register on the network. His IMEI was 'Unknown', so apperantly I wm assuming that the flashing went bad.
Last night i tried:
- Flashed CM 11 official
- Flashed Google Edition 4.4
- Flashed Stock 4.3(H3G)
But nothing worked. I was getting some notifications from KNOX and remember reading that it sometimes it messes with flashing ROMs.
So basically my question is ehat can I do to get the IMEI back. I do not have an EFS backup (nor any backup in that matter). I am dont know what info should I provide to ease you guys in resolving this issue, but will do on demand(and eventuwlly with little info on how to get it ).
Any suggestions are welcomed and appreciated.
NOTE: I AM NOT DOING THIS AS COMMERCIAL SERVICE, NOR AM RESPONWIBLE FOR THE CURRENT SITUATION.

Hmm... Actually it is, I think.. I seted it to ON, but after that I re-flashed stock. (Shouldn't it change the value back?).

I really don't know...my efs folder empty and i cant get an answer to fix it...if you still have the folder FactoryApp in efs you should be able to edit it back to on to fix factory mode issue...but without imei being right you wont have service...i flashed stock and got mine back and all my stuff works just can't exit factory mode...
