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 was been having some problems with the charging of mi SGS3 and decided to put it back into stock rom and use my warrenty to fix it.
When I was flashing to the stock rom, it failed and everything on my phone was gone. After hours of trying I finally found a ROM that worked (4.0. one). Even that ROM doesn't work properly (+ its in fabrication mode or something)
NOW
the most important thing is that my IMEI was gone too, completely, no recovering via EFS, tis COMPLETELY gone. Is there a way to put it back in? I still have is (back of my phone), is there a way to just put it back in the efs folder or something? I have been searching the forum for days.. NO result, so I decided to post a thread myself. I did come across a link to a thread but it seems to be deleted?
I really hope somebody can help me... Hate using a backup phone, I want to smash it!
Thanks!
PS: it is a GT-i9300 and I'm from Belgium if that helps with anything.

You will need your receipt or invoice .
It is not a warranty repair as you flashed stuff but you may get away with it .

Ok thanks man.. and what if i bring it to the shop where i bought it (they will send it up to samsung), would i risk it?flashing is allowed in europe i think...
no, flashing in EU doesn't void the warranty if something else is the cause of the problem. in your case, flashing IS the cause of it.

As true as that is, in practice it is not always that clear cut. Loads of Europeans get conned out of warranty repairs for having customised their phone.

FYI: I took contact with the closest Samsung center, explained the issue and they told me they will try to fix it under warranty.
Just one last question, if i set the binary counter to 0, is there any way they will notice I did flash it?
it also has to say "no" and "official"

If you've tried everything else, I suggest you take it to Service Centre near you. Looks like that fall is to be blamed.
P.S. Please post device related issues in their specific forums. That way you will get faster and better answers! :good:

im out of warranty and i took it to service center but they tried without success Due to baseband and imei unknown problem,the guy told me that it is software he flashed it several times but it didn't work,so i have to take it back,i will try the link and give u feed back,thanks for your help
i tried that link but unfortunately it didnt work may be is because i didnt have backup of esf files i missed some of the files like .nv_data i only have nv_data.bak,
So, your SIM card lost contact when the phone hit the floor and then instead of trying to remove the SIM card and put it back in you went and flashed the phone to solve the problem and that resulted in loosing IMEI number?
The Custom Rom you installed didn't make backup of your EFS folder?

yes exactly when the phone hit the floor and then instead of trying to remove the SIM card and put it back in i went and flashed the phone to solve the problem and that resulted in loosing IMEI number, but before i flashed it i made a backup of my rom using twrp but after this crash i restore my rom using the same twrp but my phone hang on booting,i was using ApoloJb_4.8_Extremev2_twrp kernel
the phone is acting very strength now,i found out even when i installed stock rom, my files are still on the phone,i used odin flashed it,please can any one provide link for me on how to fresh install stock rom and clear everything on the phone
How to install stock rom ? Search. This has been covered here thousands of times over the past two years, I'm not about to regurgitate it because you can't be bothered searching. Get a stock rom for your carrier/country from Samfirmware, then read the guides/tutorials stickied near the top of the General section.
If you want this fixed it's going to take a bit off effort on your part, we can't do everything for you.
Have you
1) Try another SIM card?
2) Look at the mobile network setting? Look for any abnormal setting? can search the mobile provider etc?
3) Try to flash another modem driver?

Hi, to add on, maybe you should tried again flashing with different modem/radio. The different ROM that you flashed may be using the same modem/radio and they may not work on your phone.
http://forum.xda-developers.com/showthread.php?t=1131950
This link seems to have mentioned various modem/radio for S2. You may want to try it. You may want to refer to another working S2 and check out what is the working modem/radio working well in your area. Then you flash in the same radio/modem.
If this still does work, it may be really the dropping of your phone has kill some physical part of your phone?

so i quickly go to recovery and flash a Modem/radio that i downloaded earlier.
after flash and it booted with good signal.
but my cause of issue i believe is kernel related as i just flash a dorimanx kernel yesterday.

Hi, i "bricked" my phone, i got a generic imei and i dont know what i did, im sorry for my bad english, i dont have any kind of back up and i deleted efs folders, please heeeeeelp !!!
Lost efs + no backups = trip to the service center.
Not to rub salt in a wound but you could have figured this from reading around a bit. Its very well documented around every efs related thread, tutorial, etc.

First of all, I'm sorry if these things are already discussed somewhere. I never owned a Samsung phone, so this is my first time here. A friend of mine bricked her SGS3 and I have to help her to get it back working. She tried to install an update and the phone is now stuck on Samsung logo, but she can access the download mode.
Since I'm not an Samsung user, can you, please, give me some easy to follow instructions how to repair the phone? Is there an repair option in Kies/Odin or we have to flash the ROM manually? The phone is not rooted, and everything was stock.
And another question, before proceeding, is it possible to save some data from the phone or no?
Thank you a lot!

Thanks a lot Yes, everything is stock on it. We will try and see. There is a high possibility that the phone is hardware damaged because she used to have problems with it and the repair center told her that there are signs of water and corrosion inside. Is there a possibility to permanently brick the device if something went wrong during repair? For exampe, if the USB connector fails or something?

There is always a possibility if the installation is interrupted anyway. But in almost all cases, things go fine so don't worry about it. Plus, flashing takes a couple of minutes.
Thanks! I managed to repair the phone with Kies recovery and now it's running Android 4.3 and all data is still there. The phone is pretty slow but it's full of apps and data so I adviced her to do a factory reset.
