Hi Guys,
Someone please help. I am not able to connect to the network to make calls. Funnily 3g is working but not able to select Airtel as my network. Dont know what to do.
Running the standard firmware but it is not registering on the network.
Regards,
Vijay.
Maybe it's sim locked.
I did reply before but my post disappeared.
It is not sim locked. Bought it on Lets buy and tried to install a custom rom. that didnt work so i reinstalled the standard firmware. and not able to connect to mobile network since then. Tried multiple versions of firmware, still on stock firmware. can check my mails and connect to the market but mobile networks are not available. Pls help.
No CSC wrong CSC set all mobile's network
settings manually .
Or flash back Orginal branded rom .
Phone firmware Country Specific Codes does not cover your network is the usual answer to the problem .

Restore your backed up efs folder as per the instructions .
failing that search for IMEI fix or flash stock firmware see if you get IMEI back .
no IMEI means unrecognised phone network will not accept it .

HI JJEgan,
Unfortunately i dont have a backup. carelessly started assuming nothing would go wrong.
I have flashed the stock firmware for india. i didnt get the imei back. trying to find something to fix the imei without any success. could you please help me with any resources you might know? Thank you for the efforts taken.
Regards,
Vijay.

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?

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.
Hello,
I have the Samsung Galaxy S II
Flashed with Dark litening rom.
Just today, this problem started. When I start up the phone I have signal for maye 5 minutes. Then I see coverage bars, but it says emergency calls only in the notification menu, and I cannot connect any calls.
I bought two of these off the same guy online about a month ago, the other one works fine so i think (hope) its not imei blocked.
I have googled it to no avail.
I have tried removing battery sim card and resetting.
I have tried a different sim card.
I have tried factory reset.
None of the above worked.
Please help.
Thanks in advance, any and all suggestions are appreciated
I checked the imei here:
http: //www . amta . org.au/?Page=405
And it says unblocked.
So it must be an error with the phone? Please help.
Thanks

Check your IMEI is the correct one that came with the phone and matches up under the battery ..
Probable you damaged EFS folder when flashing a rom .
Restore your backed up EFS folder .

Do a factory reset, wipe data and cache from CWM recovery if you have it, or flash a new rom. (Backup anything you dont want to lose).

Hi! i experienced this issue with my Samsung Galaxy S2 after flashing ICS rom. It's weird as well that when I transfer the sim to different phone and place it back again to my phone then it works but the moment I reboot my phone then I will get the same issue...
Same problem
Same problem right here about a month in to using CM7
Going round in circles...
I've now tried all sorts.
Wipe caches, factory reset, different kernels, different modems, new SIM card, battery & SIM out, reboot, chec ed if phone is barred, checked if IMEI has changed, all sorts....
Still no luck.
Can anyone help?
I found out what the problem is.
The same thing happened to me.
Emergency calls only, couldn't connect to a network, out of service state, IMEI was fine.
I went to the network operator that sold me the phone, and they scanned my phones barcode and told me the phone is blacklisted.
Go to your network operator and check if this is the case. I'm 99% sure that it will be. You ought to be able to unblacklist the phone

Sadly 99% of those with a problem have not a blacklisted IMEI they just broke the EFS and never bothered to read the fAQS and GUIDES .

And have you both asked your carrier if the phone is IMEI blocked & absolutely positively 100% ruled out a carrier side problem ? (Given a lot of these problems tend to be carrier side one way or another).

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 .
Wrong modem unlikely .
Best to restore phone to original firmware .

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).

Have u tried restoring With Samsung Smart Switch
No i have not tried
Try restore it with Samsung switch, if not you'll have to find a way to change the imie no. Back to its original otherwise your network won't register the phone to you.
I got the same problem... I guess the IMEI has been altered or the update failed... i tried to downgrade to 5.1.1 but impossible. :/

I'm also having trouble. I bought my phone out of an independent shop, on purchase they told me it's not possible to update, and basically got the phone at a bargain. But, I have been doing digging. My guess is they have bought a blacklisted phone and flashed a cert to fix it. So my question is.. what is a cert? Does it contain the imei info, and is it tied to the software version the cert file? And will it ever be possible to flash a MM rom. I have tried and it won't go past the Samsung logo, only 5.1.1 Roms work :/
