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.

I got my samsung galaxy s2 this month. Everything is ok until the day before yesterday. When I try to make a call, it says "mobile network not available". I go to the setting--->wireless and network--->mobile networks--->select/unselect use packet data, there is no icon indicator it is activate as it should be. I tried the factory data reset, but the problem is still unsolved. Thus far, call/message stop working. Wifi is OK. Do you have any suggestion on that? Thanks.
Please check your IMEI, and your Baseband version.
If they are not available, you will need to restore your EFS, if you do not have a backup, you will have to visit Samsung Service Center, or repair the EFS yourself.
Do not use another phone's copy of EFS as it is illegal to modify or clone your IMEI number in most (if not all) countries. You can however use someone's EFS backup, and mod it with your phone's IMEI if you know how to.
Hi,
I'm in this horrible situation: no baseband, no IMEI. By ny chance, do you know how to get a EFS backup and change to my IMEI?
I appreciate any help. I was trying to make a call, the person on the other side could not hear me. I reboot and...lost my baseband. Checked IMEI, it was also missing.
Thanks

have u solved your problem? I got something quite similar...
In my sad experience, your only chance is going to Samsung and ask them to restore your IMEI. From what Samsung in BRazil told me, it should be in the same country of the device. As my device was imported from the UK, Samsung Brazil could not do anything, as IMEI database is Country restricted. I believe this info is correct as the representative was very helpful. It did not look like a lame excuse. If your device is not under warranty, it should not cost you more than U$ 50. That was the price here, and everything in Brazil is so expensive these days.
My solution was to buy another Galaxy S II in Brazil as it had been released here in between the time I imported mine and the time it got screwed.
Wish you good luck.

I have the same problem, but if I take out the sim and put in another phone, it works, and if I took another sim (from another operator) and put it in sgs2, it also works, just this sim not working in this sgs2. Is this operator controlled by apple and trying to block sgs2 devices?

Thanks
I've got the same problem...
does anyone have came up with a good solution?
Try this
Root your phone.
Go to efs folder in root. Go to imei folder in that you will find a file named mps_code. Edit it using root browser from market. Erase everything and type your original imei no. and save it.
Reboot your phone and now check.
Cannot guarantee it but it worked on mine. Good luck

All I had to do to go to the Access Point Name ('APN') settings and change the Authentication Type from its default 'Not Set' to 'None'. After that, my internet is working fine.
It would appear this may be an issue common to a number of Chinese phones, so hopefully this will be of use to other people in the same situation.
My previous phone was Walkman W8 and i used to root the phone and install custom rom and stuff and i was using the custom romed phone for a long time..
Then i got Samusng Galaxy S2 GT-I9100G and stared custom roming and rooting stuff.. After losts of soft bricks and hardbricks i managed to install rootbox rom with codeworkxx custom kernel in it..
But when i booted the the phone then the phone didnt detect sim card i tried restoring to original OS it sill didnt work..
Then i came across efs problems in xdaforums.. So i tried to use efs pro v1.7.14, backed up my efs and tries to restore them.. It didnt work then i downloaded a efs.img online for my phone and tried to restore my efs with that.. I didnt work also..
I tried to restore my backup and efs pro showed me this error...

take it to warranty
I have the same issue and i made lot and lot of reasearch about the EFS folder, IMEI recovery, etc etc, and i concluded that if you still have warranty return the phone to stock and take it to warranty (mine is with samsung warranty since yesterday).
I'll update you if they could fix it.
So I guess there is no other way then..
Anyway thanks for the reply.
My flash count is 7 will they accept my warranty if I restore the phone to its original self and give them...
Is there Anyother Way using Odin to repair my phone..
Badly want my s2 back
OK. I looked here and there and got my efs folder back...
But still my Sim dosent work and also have a problem with baseband version, my phone says base-band version unknown..
You need to flash another modem, but before that enable Flight mode.
Well if you still want to put your phone in Samsung for warranty flash an ICS ROM and then use Chainsfire Triangle Away application to reset your Flash count.
That way you wont have problems with Samsung.
You have the application in Market or in a post in this forum, market its 1.75 € if you get it from the forum its free.
Guys thanks for the replies...
:fingers-crossed:
But some how i got my S2 to detect my SIM card by flashing stock modem..:good:
The modem that worked for me was DZKL3 stock modem... now my unknown baseband is solved.. And my phone detects the simcard but still not perfect have lots of bugs..But even though my cell detects my sim card when i try to call or sms i get "Not registered on a Network" warning...
Now i am stuck up there....What to do from here
Have you tried to switch operator in cellular networks settings?

Is your IMEI 004999010640000 ? Whatever you do, don't post your IMEI (important) if it's different from this, a yes/no answer will do.

YES!
In that case you have the generic IMEI. Your original IMEI is gone. Sounds like your carrier blocks access to devices with non-unique IMEI's (lots of carriers around the world do this; some don't).
Restore your EFS backup if you have one (lots of threads on here detailing how to do this), if you don't have one it's either a service centre job (which you'll probably end up paying for), or you can contact a member on here called Odia by PM who might be able to recover your EFS/IMEI for you (for a small donation; much cheaper than paying Samsung/an authorised repairer to fix it).
Thanks Mate:highfive: this helped me a lot! Hope this solves my problem...:victory:
Sorry for posting this again...
I think i already know my imei number so is there anyway that i can restore my imei number through terminal, or using an external application....
If so can u guys help me... Thanks...
Without an EFS backup, no. Only Samsung/authorised repairer can fix it (Odia can sometimes as well with whatever form of magic he uses to recover them).
IMEI's are a unique device identifier, I.E your IMEI is unique to your phone. Changing IMEI's or transferring them to other devices is illegal in most jurisdictions throughout the world.

I didn't say that. I mentioned it because whenever we get these threads on here, the conversation invariably turns to 'can I change my IMEI or transfer it to another phone', that's all.
You only have the two options. I'd recommend you contact Odia via PM & be patient.

This thread is outdated and not related to the new problem with EFS coruption. Solutions proposed here wont help you if you lost your network after downgrading a ROM from MF6 to earlier.
Ok it's not the first thread about this but no one seems to have an answer. I'm trying again.
I flashed a custom ROM on a friend's phone i9300. After the flash the phone keep saying "Not registered on network". I tried everything I know.
I changed modem
I changed ROM (3X) (with full wipe)
I returned to stock
I installed GetRil (changed the baseband)
I installed Galaxsim (phone already unlock)
when I try to set the APN I get a message "registered on network" but when I do a phone call I got "Not registered on network"
Is there anyone who knows any way to solve this problem?
New sim? What all works?

Get a new sim from your carrier. Either your sim tray is broken or your sim card is. Sim card is cheap/free to replace so try that first.

sounds like (both of you) your EFS folder is corrupt - the only way i've read of repairing it is to have a back up. service center for repair is the only option AFAIK.
The IMEISV means nothing, don't even worry about it. Know what you're talking about before you blurt out crap.

Usual suspects .
Sim you tried another .
Sim carrier unusual to be damaged .
IMEI wrong .
No phone number details standard with many roms .
Network details not entered or incorrect or wrong CSC .

First I restored the phone with the nandroid backup I made just before flashing. (still not register on network)
Then I restored the phone to stock Samsung with Odin (still not register on network)
The IMEI is still there(most thread I read with this problem people lost their IMEI)
The phone can connect to the network because it can retreive the time from the network.
If I make a network operator search it finds China Unicom(This is my sim card) and when I choose it it says "register on the network" but as soon as I try to call, I get the "not register on network" again.
I thought the IMEI might be block as it might be a stolen phone but I made a search on two IMEI database and it says CLEAR.
I flashed 3 Asian modems( I used to have a S3 I know the XXELJ2 was working with my sim card) and same result.
Have you tried flashing a different modem to your device and reporting the problem to your provider.
May sound obvious but the provider's logs may clearly show what is wrong and they can report it back to you.

Hey guys, had a very similar problem to kremata (everything in EFS folder seemingly ok (IMEI and S/N were fine)), and for me it got fixed by applying Azira's Patch ( http://forum.xda-developers.com/showthread.php?t=1918601 ).
However this solution only works by rooting and if you try to return it to stock it will reverse to being a 500$ PDA sadly.
In any case, the phone is now fully functional (calling/SMS/mobile data).

My phone developed the 'not connected to network' problem which I'm suspecting is down to the IMEI on the software (004999010640000) not matching that on the back of the handset. I've seen the solution in the FAQ but that seems to be for rooted phones. My device is completly stock. Is there an alternative method or do I have to root my phone to get it to function again?

If you dont have backup of system search for 123unlock download use test user make repair imei in advance option insert your sn and imei and start.pay 25 euros and repair imei.make backup of efs folder for future.2 things, sgs2 must be rooted and on android 2.3.6.
My network provider has agreed to repair the phone if I send them it after a second phone call.
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.
