Hi!!:
After reading and reading and trying every method i found on the internet, i still have not succeded with my problem which is this:
I tryed to flash an stock 4.3 to my free s3 movistar chile, but when it rebooted and after i wrote the pin code, it asks me for an unblock sim code
It presented signal but uknown network. I got back to 4.1.2 thinking that it should repair this, but no, it was worst, i got imei null,
After searching and searchingI found a cwm 3 files patch on the internet: one for cleaning kernel, other one to install kernel and the other one to install modem, and with it i got my imei back, (this is when i made efs backup, i know i sould have done long before ) but also the wknown network problem, with the phone asking me for this unblock sim code again.
I used galaxysim unlock to try to repair this, but it showed me that the phone is totally unlocked i think i remember it also showed me the state of csc and it appeared blocked, so i think this is where the problem lies, but i couldnt find any info about this.
when i go to state of the phone i see this
network: uknown
kind of network: umts
service state: out of service
mobile network state: disconnected
imei:3537.... thats ok, fits with the one on the back of the phone
device state: modified
(sorry if my einglish is not very accurate)
So resuming: my imei number is ok, wifi works ok, but even though the phone shows signal, it presents uknown network, and i cant do or receive calls.
i would be very thankful if any of you could help me
Your phone was unlocked using a crack that only worked on 4.1, by updating to 4.3 you've corrupted the efs folder.
You now need to buy an unlocking code and pay for a repair, make sure it works on 4.3 before you accept the phone back.

Thanks a lot for answering!. So, if the phone was cracked in 4.1.1, is there any chance to downgrade to that version, use the corrupt efs backup that i have, just in case i lose the imei, and try to unlock?, or would be too risky?
Not without a backup of the efs before you upgrade, no.

my friend gave me SGS II with the following problem:
when dailing the phone just close the call
when dailing to phone its just output busy signal.
1.Phone is not locked to any Carrier (i checked).
2.has bars when inserting Sim Card.
3.Rooted/Custom ROm installed.
4.Phone see the Sim Card Carrier.
5.Mobile Network state is unaviable.
6.Serial Number is unknown
OS : 4.0.3
Thank you
Have you tried turning it on and off again?
Sent from my GT-I9100 using xda app-developers app
Try a different modem. Here is the modem thread!
All are CWM flashable and there are specific modems for Three and Orange available.
well i tried serveral modems and still the same result
if it the phone was decleared as Stolen is it possible the effect
if so can it be fixed?
full wipe and try again
also had the same problem, you probably flashed a rom on your previous rom
or maybe the rom doesnt get your apn's.
try full wipe and flash rom again, for me it did the work
First you need to know where your friend got it from.
1.If its possibly a stolen phone then it may be locked by IMEI by the last carrier used.That makes it completely useless.A phone locked by a carrier once declared stolen can not be fixed.
2.If when flashing the custom ROM the IMEI or EFS folder has been corrupt or wiped then it wont make or receive calls.
Check the IMEI number (*#06#) and make sure its the same as the one behind the battery.If it is and your friend found the phone then it may be locked as a stolen phone.
well the IMEI behind the battery is similar with the phone IMEI..
what do i need to do in order to make the phone to output/input calls?
So basically it sounds like a stolen phone, in which case you can do nothing and you will get no further help from me or this forum.
well thank you ill return it to my friend ..
It has to be the same not similar.If its only similar then its corrupt from a bad flash and can be fixed but if its the same then yes Im afraid as posted above it does sound like a locked stolen device.
Hi guys,
I've messed up and need help. Here goes...
I had a locked phone on the 3 network , a S3 I9300; and I wanted to unlock it. Simple I thought to myself.....anyways, I downloaded the voodoo unlocker after rooting successfully with Odin. Nothing happened it wouldn't read my T-Mobile sim card and I can't remember what I did exactly but I did press some buttons on that app in attempt to unlock the sim. I then realised that it was not compatible with the S3 and then I proceeded to use the GalaxSim app. I had to download busybox for that, after doing that I attempted to unlock it. Yipeee! Phone unlocked and everything green.....but not. I still couldn't register on any network(using manual method as well). I had even cleaned my SIM card(but not tried another sim card). I then unrooted the phone with stock rom and unrooted again to use GalaxSim......and pressed backup accidentally! That I means I am now with an unlocked efs folder as my default efs, I didn't check the IMEI number to see if it changed, but how I return it all to normal? Has my IMEI number changed or would it not show IMEI if I overwrote the EFS folder?
I need help, I'm confused.
What phone you post I9100 ?????
No or broken EFS then just restore your backed up EFS .
jje
sorry i9300.
No, the EFS I had was overwritten with the newer version when I reinstalled the app. Now I have only one EFS and that's the one currently installed(which says the phone is unlocked). The phone is not registering on any network. Is this a baseband issue or a unlock issue? The app is showing unlocked, it shows all the networks, but some are written as"forbidden networks" and I can't connect to any.
By the looks of it, the simlock will never return.

You cannot update an EFS with a newer version you can only restore your original backed up EFS .
Does the IMEI match that under the battery if not its a service centre repair .
jje
Oh and the platform is jellybean.
The imei is the same, but it is still "sim unlock". How can i redo the process?
your phone should be fine you restore your original imei or just copied your origanal imei again probaly for the best as you know you have a back up of it now
chances are your phones unlocked now and probaly just need to register the sim card with T-mobile to activate it
should always place the back up of your efs somewhere else aswell incase things do go wrong mem cards can corrupt
Both sims that i've used are contract. I can't register any. They all say disconnected on status settings.

Hello! I was having issues with my SGII since I lost my IMEI and I struggled to recover it You can check my story here.
Now I have mi IMEI but my phone is network locked. I tried to unlock it with Galaxy S Unlock but it didn't work.
Tried with GalaxSIM and after reboot it says is unlocked BUT my IMEI is lost and obviously my phone doesn't recognizes my SIM card.
I'm on Android 4.1.2
Build Number:JZ054K.I9100XWLSE
Kernel:3.0.31-Siyah-s2-v6.0b4
Baseband: I9100XXLS8
If my EFS folder is corrupted shouldn't I lost my IMEI?
Why I lose my IMEI after attempting to network unlock my phone?
Here are some images.
First everything is normal, I have my IMEI and stuff...
Unblock successful!!!
But after reboot, my IMEI is lost
And so my signal...
Thank you!

I don't have warranty anymore.
I'm currently traveling ( in other continent for 3 months ).
I don't have my ticket purchase with me.
To trigger this IMEI problem I have to attempt to unlock the phone... so I need to root, reset the binary counter, and then re-flash the original firm, after that binary counter won't be zero.
Hi guys,
This is my first thread and I've just recently began rooting and flashing roms etc.
I'm sorry if this is a duplicate thread but I searched the forum and found nothing. Here's the thing:
I have a Samsung GT-i9300 ( international version ) and after the first flash I lost my efs folder.
Which did not only mess up my IMEI. It messed up bluetooth, connectivity, wifi adress and the phone lost it's identity.
I took it to a " technician " who said he could fix it. He restored my imei, but the network wouldn't work. So he put another IMEI and voilá!
The phone had connectivity and worked perfectly. So he told me that my phone's imei was reported as stolen because the network wouldn't let it connect. ( and I have had this phone since it first came out of the box and I never reported such a thing. )
He then said the police would have to be involved to verify if i'm the owner so I just told him to put a new imei on.
When I picked up the phone it was working fine. Full connectivity. Then I flashed a rom and lost my efs folder again.
Luckily I had a backup of the imei, wifi, serial and bluetooth adresses. Which were sucessfully restored.
But still, no connectivity. So I googled it and finally found a solution! The problem is with the Baseband.Basically the phone lost it's baseband files, without which the phone cannot connect to the network, and when the " technician " restored my imei, he copied the whole EFS file from the dead phone. Which then replaced the missing files and the phone worked. So my IMEI wasn't blocked, my EFS file was corrupted and the baseband files were missing.
I used the Ariza patch. And voilá, the connectivity is back. But after being turned on for about an hour, the phone has a pop up which says it's not registered in the network and it must restart with a valid sim. And it's a no option pop up, you are indeed forced to restart your cell phone which is annoying because it shuts off at night and operations that take more than an hour are impossible.
But still, after 2 days, the ariza patch stopped working. The phone is in Emergency Calls only now and it doesn't detect the sim. But it's not blocked, it connects to the network.I read that you could flash the modem files to fix this aswell. So I downloaded the modem file for my phone, from my carrier ( VODAFONE PORTUGAL ), from one of the threads here. It didn't work.
Now, this is the question:
Is it possible that it didn't work because my new EFS file is from a phone based in the UK and my phone is from Portugal?
Can it be a sim software problem?
Also, is there any solution found other than the obvious which I've already exhausted ( flash stock rom, wipe cache, etc )
Thank you an Advance guys!
Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...
