Hello,
i haven't rooted pohone, everything is on the stock firmware, but yesterday my SGS2 lost signal. Now is there still no service icon, imei is blank, baseband unknown.
Stock firmware version are:
pda: I9100xxki4
phone: unknown (was I9100xxki4)
csc: I9100XAKI4
I found, it is efs directory problem, but i have not root, so i can't access it.
It is possible to repair it myself? If yes, which stock room i have to choose to fit best for my phone? I tried through samsung kies software, but it couldn't detect my phone (still connecting).
Thanks
Sounds like messed efs folder but I can just think how in hell that hapened. But you haven't backup of that. Pretty much you can just take it to samsung retail seller or someone who can do JTAG repairs

last things i done was: installed osmos hd (game, it wants only internet permission), and send few sms ... after few minutes i saw that the singal was out
If you haven't messed with/flashed anything on your phone & this is happening with stock firmware, take it back to have it repaired/replaced.
If you haven't been mucking around with it, you shouldn't have any dramas with warranty service. If you do go down the path of rooting the phone/trying to fix it yourself, you may well bork it so badly you need to return it anyway & you may end up with a lesser or no chance of getting warranty service.
If it were me, I wouldn't risk it.
Some report fix with KTool.

Others have fixed by flashing a stock rom .

Hello,
i have a problem with my I9100G. It has the known IMEI 004999010640000. I want to repair the IMEI back to the original one.
Who can help me with that via teamviewer. The phone also always ask for a network unlock code when the pin of the simcard is entered.
The phone is/was a free one which acceped all cards. But now after the crash it do not accept any card without asking for a network unlock code.
If someone can help me it would be great.
I can also make a payment via paypal if someone help me with success.

First of all, never ever give an IMEI over the Internet, especially your true one. It is enough to mention that your IMEI has been modified. IMEIs can be stolen and in some countries there is a blacklist of them and you risk getting fined or, in some instances, prison.
Now, what ROM are you on? Usually IMEI corruption takes place when you flash custom ROMs. What you should try is flash a stock ROM on your phone. I know my brother has had the issue on his I9000 and he managed to bring back the IMEI by flashing a stock ROM.
If you have a backup of your /efs folder you should restore that. If not, for future reference, you should use Root Explorer or any other file system explorer to backup your folder and have it ready in case **** happens.
Some Kernels, including Siyah Kernel back the folder automatically.

Hi all,
I recently lost my IMEI number (I do not know how, I did not install any weird apps).
The IMEI number says unknown, the network does not work.
Some things to note:
I am not rooted, never have
Using official FW 2.3.3
Never made EFS backup
Have original box (with IMEI number might help?)
Did not install any malcious application
I have read that if I root the device and try the GSII_repair it MIGHT fix, but I don't want to run into more trouble having to result in a BRICK or anything.
Is there any way to restore the EFS thing without having to resort to Samsung?
Solution?
You might need to root your phone.
Since it only needs a new IMEI number you could backup all of your apps and settings and reflash the same firmware and finally restore apps.
This will almost likely require you to root

Good luck and don't give up!:fingers-crossed:

I tried rooting the phone,
I tried the GSII_Repair, no luck.
Any hope?
Without a backup, no. If you've never messed with the phone (not rooted/not run non-stock firmware) & you bought the phone new, your warranty should be good. If so, use it. If not, it's either pay Samsung/authorised repairer to fix it, or ask local mobile repair shops. You may get lucky.
Hello People
Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.
I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.
Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.
I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?
Many thanks.

Flash a patched modem and kernel from here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << see if that works if it doesyou will always need to use the patched files.
Thanks tallman43! I'll try that. Also, I noticed now that the EFS folder is EMPTY :/. and the backup .tar I made with CWM says it's 0 bytes? wtf?
still, in phone info, imei and s/n are there. weird?
THANK YOU

Your recommendation worked like a charm. My signal is up and running normally. MANY THANKS tallman43.
Lastly, even if I sometime I decide to try out a custom ROM (unlikely at the moment, but who knows?), I still have to flash patched kernel&modem? or in case of factory reset (I will be selling the phone soon) ?That custom really messed up my phone...

I would still like to solve the problem at its roots: to fix the "not registered in network" problem whenever factory reset or stock ROM flash via odin is done. That is simply not normal. I might be selling the phone soon and the new user won't most probably know he/she would have to apply a patched kernel or etc.. ( let alone about rooting the phone).
Basically, bring the phone back to it's original sound state before I tried out the custom ROM. What can I do about that?
Hope I'm not being annoying.. just trying to get to the bottom of things

There is nothing you can do without your original efs backup.Only a service repair can fix it.

Understood. I think I have the original EFS in my SD, though I tried replacing it once and it didn't work out... I suppose I'll have to make do. Thanks for everything man
Flashing modem with Ariza patch was bad idea. Your efs folder is screwed up now and you are addicted to constantly flash this dirty workaround.
If anyone have problems with registering in network please check your device serial number first. It must be the same as on the sticker under battery. If it's not then type *#0011# and check info under IMEI CERT. If there is FAIL info then you should use any box ie Z3X to correct phone's serial number. It takes only few minutes and is cheap. It's better long-term way than patching and permanently destroying your efs informations.
If you have backup then you should flash normal modem and restore original efs partition. Then find any GSM service center with box and tell them to fix serial number. It shouldn't cost more then 5-10 dollars.

I have never flashed the Ariza patch nor have I even mentioned it on my previous posts explaining the problem. Fixing the s/n issue is indeed adviseable, but paying to correct s/n using box here where I live is ASTRONOMICALLY expensive. They should answer for never having fixed it, but they won't. Here is a hell of a lot more than 5-10 dollars, unfortunately.
Believe me , I'm no happier in applying this sorry fix every time I want to factory reset or upgrade, etc; it's the only option I have left at the moment.
Those files you have flashed, I mean kernel and modem are patched with Ariza's method. It is called Ariza patch and it is latest solution you should take to resurrect your phone because it is a destructive one.
Sorry to hear that you can't repair it as it should be especially if you want to sell this device.

May i ask a few questions about your problem?
Which version were you using when you desided to use a custom rom?
Was your phone ever rooted before installing a custom rom (when you were on official)
Did you upgrade your phone before? (Official via ota or odin)

I was on 4.2.2 leaked version ROM some guy installed at a repair service some time ago when the phone belonged to my mother. I was actually rooted using the CF AutoRoot method, with Philz CWM recovery. I decided to change to a custom 4.3 without having changed first to a stock 4.3.
The problem came when, within the custom ROM's aroma installer, I ticked an option to upgrade the modem to some build I can't remember now and my signal became screwed up. I informed this in the developer's custom rom discussion thread about the issue to which he replied that the problem was that the EFS folder tried to convert from v1 to v2 and failed (this was when I learned of the whole efs version folder change since build XXX (don't remember).
I download a stock unbranded 4.3 ROM and flashed it via ODIN, believing that would solve the issue; it didn't. Finally, I became desperate and took it to a repair service where they used box. Apparently, late did I notice s/n was not the same as the one in the back of phone. I'm guessing that would solve the problem? I don't know.
i am sorry for your loss . i wish you had all that info you learned before a try and fail. now that your imei number is a clon number, and once a box tempers with that you cant go back even if you have your orijinal efs folder or backup. you should always have that 2 patched modem and kernel files on your sd card just incase. you can use custom 4.3 with the patched files and get a signal but you will always have some lags after some time because of the kernel. and lucky you samsung stopped updating s3 officially because patched files are only for 4.3. if you dont have a desire to use custom 4.4.4 kitkat roms then you are good to go and when it comes to sell the device, the price will be much lower then an original s3.

Well, actually, IMEI didn't get cloned; of that I'm certain. IMEI is just the same as it was before I took it for the first time to repair service. It was the S/N that got changed somehow. Should I get them to correct the S/N, and use the original EFS folder (I found it, i think), would that correct all problems?
S/N number is the same with imei number as when you dial *#06# . And as i said before you cant go back even if you have your original efs folder. Dial *#06# and check your imei number from an " imei check site " you can find on google search. That will tell you what i mean.
There are: IMEI, device serial number and Android serial number. First two numbers are on the sticker in battery Bay. They must be correct because are used to authorize IMEI certificate.
Samsung's IMEI begins from 35.....
Serial number usually from RF......
If you see serial number in HEX format in phone's info section, something like f1abcadef1.. than it is android not device serial number and this mean troubles with authorize SIM card in operator network, even if it shows proper signal power.
I don't know there is any secret code to display serial number but there is plenty of phone's info apps in playstore which displays this alphanumeric string.

I have replaced my S3's broken screen with a new one. The think is now i have "baseband unkown" and "IMEI unknown" and i can't make any calls. I have no network. I have read numerous threads here on xda and elsewhere but nothing seems to work. I haven't backed up the efs folder nor the IMEI. I don't even have the original screen with the IMEI on it. (If i only i knew back then) . I don't even know what version of I9300 i have. I think is the Exynos one. I have installed many Stock roms with different firmware and custom Roms but nothing works. I even tried to flash different modems but still nothing. Is there a way to find my IMEI and restore my baseband? Now i am on lineageos 14.1.
There is only 1 model of the GT-i9300.
If you flashed the latest stock ROM with Odin and the imei does not reappear, it likely that the EFS folder has been corrupted. This can be corrected by flashing the phone via jtag but you will need the original IMEI.

So basically it's a lost cause. I don't have the IMEI. Is there a way to read the IMEI that is hardcoded on the board?

Not that I know of.
Do you have the original box, receipt, or cell contract? The IMEI is sometimes printed on these items.
