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.
Hi,
I purchased a I9100 secondhand online, the previous owner tried unlocking it and corrupt the EFS and it was not recognizing the SIM when I got it.
So I flashed I9100XWKK5 and have run the repair tool on play store and tried deleting EFS manually (after backing up) also run EFS Pro but no luck in putting my IMEI back on.
I have come across this tool unlocksamsungonline.nl/unlock-samsung-I9100, they claim to be-able to fix the IMEI, before I buy the login has anyone tried this before and does it work?
TIA

Users have mixed results when repairing /restoring the EFS folder. You can search and I mean thoroughly search every folder on the phone for a backup of the folder. Previous owner may have rooted the phone and many custom Roms and kennels backup the EFS folder as part of the installation process.
All the best

I have searched through the phone and cannot see any sign of a backup of any sort, any other ideas? or should I go and try this software from unlocksamsungonline.pl
TIA
No backup means you have 3 options:-
1) Service centre/authorised repairer.
2) Local mobile repair shops (you may find one who is capable of doing the things Odia/service centre can do).
3) Contact Odia by PM & wait patiently for a response (which means no sending him 'reminders' - if you do, he'll quite rightly ignore you. He isn't your servant). He may be able to recover your IMEI (for a small 'donation'). But on the other hand, I'm not even sure if he still does this kind of thing (he used to). I cannot stress the 'send him 1 PM & wait' enough. You may think this is urgent, he won't. So if you do go down this path, respect that.
SHW M250 no signal after flashing to I9100 ROM
I flashed my SHW-M250s with I9100 4.0.4 ROM, everything was working good for about 2 months,
suddenly my IMEI changed to 0049 fake IMEI and I lost signal on SKTEL.
I tried to reflash with SHW-M250S after that my IMEI is ok but still no signal and an unknown text appear on the home screen whenever I flash with SHW-M250S ROM, (SCREENSHOT ATTACHED). also I tried different ROMS of SHW M250S and still same problem.
whenever I flash to I9100 my IMEI changes to 0049 fake imei,, and when I flash to SHW-M250s no signal and an unknown text but the IMEI changes to original.
I tried to insert different network SIM with SHW-M250 S ROM, it was working, but still that annoying text on home screen is there.
Also I tried everything on this Forum , try to repair EFS folder etc but no luck.
Do anyone has the idea...?
Please reply to me.
You're mixing thing up here, try backing up your EFS folder while on m250s, make sure you back it up with 2 or 3 app. (ktool and simlar).
Keep flashing your devices ROM till you get all networks going and stick to the cell's original region.
Now, once on I9100, start with GB ROMs.
And then some, try sii_repair from play store and give it a shot at restoring those previous back ups with the same tools.
Try to keep them ROMs apart till you solve one of the two issues.

Thanks for your reply Bro.
I tried everything you mentioned but still no luck.
Is it possible that SKTEL has blocked my IMEI on their network.
While I still can access other networks..?
Check you IMEI status online.
Don't think so tho, if it would be blacklisted then you wouldn't be able to use any nerwork.
Are you using the same partition lay out for m250s & I9100?

I am using diffrent PIT files for each I9100 and M250s.
On the online status it shows an old model of Samsung, not the SHW-M250s while it says IMEI is ok.
Alright, when in "I9100 mode" flash from GB to JB (thru ICS 4.0.3 and 4.0.4).
We need to see if you get your IMEI right at some point on those ROMs.
Flash CM 10.1 to see if that helps.
You're not having any trouble with m250s ROMs right?

Can you give me the original CSC, Phone, PDA, Bootloader link of SHW-M250s, and I am having problem in SHW -250s as I attached the screen shot. some unwanted text appear on the home screen, which says CSC: Unknown, PDA version etc.
And now:
My phone is not starting in SHW-,250S after flashing one of the I9100 ROM , CSC, MODEM from sammobile
I've got no idea about your device's model.
Check the thread posted in the general forum, they've got a site in which you can download ROMs and all.

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.

Hi everyone,
What would be the general steps to take to update to 4.3 from 4.0.4. I messed up my phone a while back updating (no signal basically, no calls, etc, yeah... my fault for not reading...) so I had to take it to a shop. They downgraded to 4.0.4 and I'm not even sure my IMEI is the same...
Anyways, how can I upgrade and not lose their "fix". I remember reading about backing up my modem, flashing then reflashing my modem. Would that be enough?
Is there any backups that I can do that will create an "image" of the phone that I can safely flash back to in case anything goes wrong?
I currently have SuperSu and I think CWM (but an older version).
Any help would be appreciated!
Backup your efs folder, then make a nandroid of your rom. You will end up with no network after upgrade, try patched modern and kernel but there is no guarantee.
Search and read for the hundreds of other people who did the same thing.

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.
However I Flash with smartswitch, and after reflashing the bootloader with odin and a Root Kernel, I can boot into the device and using root explorer, I CAN see my EFS folder. I deleted the .nv_data.bin files and changed the .nv_data.bak to .nv_data.bin (was an older date) and I now have the network options back but a generic IMEI and can't register on a network.
I feel SO close to getting it up and running, but if smartswitch can't help, not fully anyway, I'm not 100% I can be rescued either.

I got 3 old smartswitch backup and i find a file with the imei and everything , do you think its possible to backup this files ?
You CAN recover your phone with smartswitch, there is an emergency recovery function with a IMEI and SN input option, some users who used the same threat (android 6.0.1) and has lost their efs partition reported that smartswitch worked.
I've done this procedure too for some weeks to recover my phone an everything is working fine.
possibly with root explorer
