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 would be glad if someone could help me.
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.

Difficult to give you any help, you haven't give any information on what went wrong.
Try posting what happened, if you have matching imei under battery to phone info and which modem version you flashed last.
You do have efs backup, right?

Does your IMEI match the one under the battery .
If not restore your backed up EFS folder .
Fail to backup its a service centre paid for repair .
Samsung Galaxy S3 General Sticky Roll-Up Thread ***Stickies found here!
If imei and serial number are not corrupted. Check your APN settings. You may want to flash stock rom to see if that works. Backing up efs folder highly recommended.

Try Ariza patch. Search XDA and downlowd apk. You may need to install the patch every time you update the software.

Dial *#06# in your phone's dailer and if your IMEI matches the IMEI on your phone's box or under battery then its something else.
If it says something like 0049xxxx or null or 0000... Your IMEI is corrupted.
In the case of corrupted IMEI you must have a backup of your EFS folder in order to restore it. If you have backed up your EFS then you're safe. If not.... Only Samsung can fix it for you, provided you have warranty left.
I had the same problem.. my IMEI changed to 0049xxxxxx by installing Custom Rom. Got it fixed for free by Samsung PM me if you want to know how.

After my phone started to get slow, i thought it was a good idea to flash a new rom on it. My first pic was the MIUI roms because those always worked well on my desire. After the rom was flashed i lost connection to my network and i saw that this was a issue that some other people have as well. I tried to do a nandroid restore but even then i still have no connection. I have no idea what to now, please if someone knows anything i would really appreciate it.
Here's how it all went:
1. Flashed MIUI
2. Lost connection
3. Flashed Cyanogen, i thought it was a ROM issue
4. Restored nandroid
5. Back to stock now
Now i'm back where i began, but still without connectivity. I see a few thread about the ESF files, but i'm missing a few files (did a full reset i MIUI).
What are my options now? Am i screwed?
Thanks.

did you try flashing the latest f/w-s i.e., XXEMG4 or later?
The fact that you said *esf* is alone enough to infer you didn't read properly. Is your imei intact ? If not Check for efs backups or else service centre .

I downloaded the rom off of the official MIUI site and it said nothing about EFS. It's not untill i came back to XDA when i first heard about it. It's just a simple typo, i know what the files are.
My phone says i have the "standard" corrupt IMEI; 6400 something.
Download an EMG based official stock rom from sammobile, flash it with odin on your pc.
If that doesn't enable your imei to be read then you need a service centre.

If i need to go to the service centre, what do i have to do? Flashing back to stock, unroot and what else? Is there anything i have to say to them about how this happened?
Thanks for the help!
No, they will work it out for themselves. There is a thread in general, stickies on how to return to full stock.

I know I should not post this thread because there are other threads with this problem.
Yesterday I was having issues with Sotmax_Ultimate_Stock_V23_XXUFME7_HD_AR ROM. It became laggy, pretty unstable bla bla bla so I decided to flash a stock ROM on my S3. After flashing I rooted my phone once again ( followed the chainfire guide CF-Auto-Root-m0-m0xx-gti9300.tar ) and went to sleep. After waking my I saw No Service and my IMEI went to 004999010640000 tho my serial number didn't change. Now I readed the whole forum and I only found the way to get back to original IMEI is to restore EFS Backup that you done. I never done an EFS backup. Everytime I was flashing different ROM I only did nandroid backup if something goes wrong and I would get bootloops or soft brick. How to get my Network working again so I could make calls and get my IMEI back?

if you don't back of old EFS folder i afraid you might not be able to downgrade!
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...

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.

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.
