Hi All,
I screwed up my phone, after flashing with a custom rom it worked fine for a couple of days but now it doesn't work. I have no IMEI and even the baseband is unknown. I have not backed up my efs, and now it is corrupted i suppose.
There are many threads on this for the captiavte but none for the s2. I even tried the methods given in the captivate thread, but dint work. Is my phone trashed for good or can i fix it?..please help.
I recommend giving additional details, such as ROM flashed Method used...etc then maybe someone might be able to help. I have idea but there's a bunch of smart people on here that may help.
Good luck!

I am really confused on how you can lose an IMEI number on a phone.

Somehow he trashed his EFS partition... I wonder what in jivy's ROM could have caused this...
This guy has the same problem?? http://forum.xda-developers.com/showthread.php?t=1386223
Edit: Oh, same person lol. Is the IMEI individual to the phone? Have you tried to "go back to stock/unroot" ? Or did you do a restore before you did any flashing/roms?
Funny that jivy's ROM is named iscrewed. I kid, I kid. It's a good ROM. I used for a couple Weeks, no problems for me.

I have no idea how i trashed my efs, in fact i dint even know something called efs existed till this happened. It was working fine when i went to bed, i get up in the morning and see i have no network. Even i dint know someone could lose their IMEI.
Yeah, I have tried going back to stock unrooted, factory reset, tried different roms, modems, kernels..nothing helped.
Hahahaha..yeah..ICsrewD screwed me..
So no one has any idea about fixing this?..or is my only bet to reset the flash counter and take it to store for a warranty claim?..or can they fix it?

If you have an original nandroid of your stock phone, I'd try to just push the efs folder and see if it helps. I had this happen on my cappy once and that was the only way I got it working again

Not sure if nandroids include the EFS partition... gotta check that.
I suggest reading through the I9100 forums - for whatever reason it happens far more often on the I9100 than it does here. In fact, you're the first person here to have a corrupt EFS.

Yeah I just looked it ins't included. Are the IMEI's specific to each phone or would it be universal to an AT&T GS2? I know I have a back-up of mine from when I unlocked it, maybe he could use that?
I tried to restore the nandroid backup..but dint work.
Yeah..probably i am the first one to have this problem here.

IMEIs are specific to each phone...
The I9100 forums are likely to have some useful threads - this is an item that is not any different between our device and the I9100.
I am trying out some methods on the I9100 forum..will keep you posted about the results.
I tried http://forum.xda-developers.com/showthread.php?t=1264021&highlight=restore+IMEI and a couple more..no luck..everything else needs a backed up efs unfortunately which i dont have.
If a nandroid doesn't back it up, how do I make a backup just in case?

You have to make a copy of /efs. Not sure if there are any particular issues you have to take into account. I think it's just make a copy of the entire directory and transfer it off your phone, or to the external sdcard, or both.
or even better,
Code:
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
I think EFS is p3 - need to check tonight.
I think I screwed did the same thing to me but I cmw whiped n did a different rom and I was good

Good one. I was going to go ahead and do this, so I searched for info on the efs partition. The only thing I found was I9100 suggesting it was 0p1. So I'll wait till you verify the correct partition for our phone.
I'm not sure when my imei was changed. i odind a stock firmware, guessing this was when it spoofed my imei cuz its not what's on the back sticker.
is there a way to change it back? i have no back up of the efs or anything like that

It is possible to change the IMEI of a device you can find a few services out there to do it for you but it is generally frowned upon by the development community and in many cases considered illegal in the united states. You are very unlikely to find out how to change your IMEI on XDA as most people will assume the worst and assume that you stole a device (regardless of whether you did or not) and are trying to keep the device from being locked out.
You will have to edit a few files in the efs folder which ones I'm not sure but in any case good luck

Yeah I have AOKP.
Thanks i'll give that a try! Now that you say that, I wonder if the MTD formatting is what causes the IEMI spoofing.
Does no one else have a spoofed IMEI running ICS on their Vibrant?
I still want to run AOKP, if I can restore my IMEI, should I backup the /efs directory, then reflash AOKP and then restore /efs? Would that prevent me losing the real IMEI?
Update: Looks like my IMEI is back, thanks! Now how to get back to ICS and keep my IMEI...
Update 2: Not sure what I did different this time, but I redid the whole CWR > cm7 > ics and my imei is good still

Does this help?... http://forum.xda-developers.com/showthread.php?t=888193
Hi there.
I have a ROM backed up via recovery and I am pretty sure I have backed up my EFS as well.
However upon restoring my phone to stock, I noticed upon boot that I had the generic IMEI number (004999010640000) and have been unable to make calls etc.
Upon noticing I had to re-root and install recovery (PhilZ Touch 5, CWM Base version: 6.0.3.3) to restore the ROM and hope it restores my IMEI which it didn't, next I looked for my EFS in a folder called EFS_Backup and in there is 'efs_05Aug2013-2257.tar.gz" however it appears to be empty.
I don't know what to do as I am out of warrenty and I thought I completed the steps, theres no .bin or .img files I can find.
Any help will be appreciated.
Thanks.
You have to restore it using custom restore from philz

you said efsBackup.tar.gz is empty so which means its 'bad' backup . so obviously it won't work.

Looks like I am f****d then
How big is the .tar.gz file? It should only be 80Kb
If zero size then yes, you are screwed unless flashing a full stock 4.1.2 rom via odin makes the efs readable again (make sure it's an EMG ROM if you've EVER flashed an EMG rom to your phone)

Just an update, I managed to get my IMEI number back by flashing the MG_Basebands.zip, however the altered EFS seems to affect the GalaxSimUnlock from working as it says the phone is "Unlocked" when it's locked to Three UK.
I am just glad the phone is working.
After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.

Did you backup your EFS? If so, restore it and a good backup. That should get you going again.
If not you may need to use flashtool and still might need to restore EFS.
There's a link to a flashable backup/restore of EFS in the FAQ.

It's question #4 in the FAQ http://forum.xda-developers.com/showthread.php?p=55225699
But if you didn't back it up prior, in at least TWRP, then it won't do any good now if it's messed up. It'll just backup the bad one.

This is as close as I know of to repair a bad EFS. http://forum.xda-developers.com/showthread.php?p=38348745&postcount=1
While its not for our phone, the steps I think will be about the same.
Your EFS may not be bad though. It's hard to say. But when I've made GSM conversions in the past, EFS got erased usually and I luckily had it backed up to save my.....butt.
This is why it's in the OP's of most of the Root, Unlock, FAQ, Stock ROM threads. If this gets screwed up, you have a lot of work ahead of you at best.
You're actually lucky to still have a working phone.
Ok well all I get is like calls and texts but then the "hands free activation" shows up runs then I have 3G but then it fails and I go back to just calls and texts. I also never had GSM with this phone only CDMA (Sprint)
So Flashtool worked for you, and you used ZV6 .tot?
Maybe try using ZV4 tot so you can still have root. Then see if you still have issues.
I was used the flash tool to get on ZV4 then I did a system update to ZV6
Can someone help please its still broken, but only on the lg rom
I think you need to go back to zv4, you shouldn't have taken the update, there's no way to root zv6. I'm not even sure if you can get back to zv4 if you took the update, you'll have to read read read. If you can't get back &byou didn't back up efs, then someone who knows allot more then me will try to help, sounds like a dead device, but don't know. Hope you figure it out.
