Hello everyone, i have a huge problem with my galaxy s3 i can't make calls or send or receive messages, it keeps saying "not registered to network" even after changing my sim card, it turned out that my imei is the problem, it shows /01 at the end and the bigger problem is that i can't find the original imei under the battery, someone took off the sticker or something, so is there anyway to change my imei or get a new one ?
No, changing imei is illegal in many countries, discussion about it isn't welcome on XDA.
Furthermore, this post is remarkably similar to one posted very recently

AS said in this post and previous post you must take the phone to a Samsung service centre .
Pointless posting here there is no fix .
REPORTED anyway breaking XDA IMEI Rules .

A while back one of my customers found a T-Mobile Samsung Galaxy S2 at a bus stop which she handed in at the local police station. Last week she went back to see if it had been claimed and it had not so the police released the phone to my customer to keep as her own property.
She was aware that it was blocked but wanted to give it to her child to use as an android game device but when she told me about it I said I would have a look at it for her to check it was defiantly blocked.
On trying all network SIM cards I could only get the 'Emergency calls Only' notice. I did a Checkmend report and the device was still listed as stolen and blocked (the police have given her entitlement paperwork for the phone which I have seen) so I guessed it would be out of the question ever being able to use it as a phone again.
I decided to root the phone anyway and install a CM stock ROM. I then also installed the 'Galaxy S Unlock' APK and zero'd out the lock codes. I then tried all the SIM cards again with the same results as before.
After some browsing on the internet I download an APK called 'HC-kTool' and installed it. I then backed up my kernel and EFS folder to my SD card before hitting the advanced key and deleting my current installed EFS folder.
I turned off the phone, wrote down my IMEI number from behind the battery and inserted a Vodafone SIM card.
When the phone rebooted I got a full Vodafone signal and rang my home number, and it rang!
I then dialled *#06# and noticed my IMEI number has changed to something entirely different.
The phone has been connected over an hour now, I have not tried any other SIM as yet but I don't doubt it is unlocked and working on all networks now.
I read something briefly about T-mobile using a non-standard (I think) network system and deleting the EFS folder has the Samsung software revert it back to a non-T-mobile modified one. this could be totally wrong though...
Can anyone throw some light on this?
Is the imei 04999010....?

Most likely a silly network that doesn't block the dummy Samsung "default" IMEI...

Indeed it is. I thought that IMEI wasn't supposed to work to make calls?
Odder n odder!
Yeah had the dummy imei too and didnt notice until 2 weeks or so had passed, thankfully i had a backup from a year or so

So are there any negatives to using the dummy IMEI then? Also, if I edit the hex of the nv_data_bin files from the backup of the original IMEI can I change it to anything I please?
I dont think you can do that as it would be stupid from samny's side but try(after taking an efs backup). AFAIK no negatives except that some providers will block this IMEI

I have dumped the efs of the default Samsung and will compare the hex in hex workshop against the original dump. I'm guessing the main file here being the nv_data_bin.
While it is good news for my customer that this ex-stolen phone now works on Vodafone I don't think it is very responsible of Vodafone to allow default IMEI numbers to connect to their network. If I had my phone stolen I wouldn't like to think that the thief could potentially use it again.
Yes mine too was allowed on Vodafone after getting the dummy IMEI

I remember reading some time ago that although illegal in allot of country's if you were able to change a phones IMEI number so as to connect to a network it would still not be a worthwhile effort as if the fake IMEI was the same as that on another phone you would get the other phones text messages and calls mixed up with yours.
I always had doubts about that as it made more sense that calls and texts would be sent to the phone broadcasting the correct SIM number ID. But I was assured by people much more experienced in this stuff than I that the IMEI was a more secure method of ID'ing the correct device to send secure DATA to.
So if this is true, surely that would mean I am the only person on the planet using the default Samsung IMEI number as I have had no odd text messages or phone calls since I got this phone. (I am now the owner as I swapped it for an 8GB iPod Touch!)
Anyone can un-confuse me here!

As far as I know the default Samsung IMEI number will only work on the Vodafone network. If you have rooted your S2 then there is an app in the Google Play store that will unlock your phone to all networks. Search for 'Samsung Unlock' and you will find it. If not there are plenty of ways to unlock it for free that you can find here on XDA.
I'm pretty sure you won't get it working on any other network without changing the IMEI which is incredibly difficult, not worth the cost of the equipment you would need and of course illegal in most country's carrying a very real prison sentence. XDA and other cell phone development communities will rightly not tolerate IMEI changing discussions and almost always permanently ban members should they attempt it so that is as much as I will discuss that!
Another thing I found recently was a company offering to 'De-Blacklist' phones to certain networks that were on the UK blacklist. At first I thought this must be illegal as if it wasn't it would make a mockery of the entire blacklisting principle, i.e prevention of crime. However more and more companies are offering this service and nothing seems to be preventing any of them from doing so. There are two UK based phone unlocking / modding businesses with a huge reputation online that are also doing it now too.
If anyone knows what that is about please enlighten me. No amount of probing I did had any of the companies reveal any of the methods to me!
I had an iPhone 4 that was IMEI blocked (found in a skip by a charity shop - checkmend reported not stolen) de-barred to 'EE / Orange' 5 days after paying about £50 to http://www.beijingiphonerepair.com/store/#!/~/category/id=4425106&offset=0&sort=normal
IMEI
If you were not cautious enough and you did not saved your efs directory before you made changes or ROM updates to your phone, then its possible that your phone "forget" your IMEI. So if you need to re-write your ORIGINAL IMEI back to that phone that its belong to, then its not a crime!!! There is an online program that can do that for around 4 EUR, 5-6 USD. If you are a half experienced browser user, you can find it by searching the keywords.
Although there is an easier way that you go to your provider and ask them to restore your phone IMEI, they can do that for you. If your wise enough, you put back your Original ROM, and zero the counter of ROM changes. As here in XDA you can find these methodes I wont give you any links, you can find it by yourself.
So, changing the IMEI is illegal in many countries but put back the original IMEI to the phone where it belongs is not!

To the OP.
Did you experience loss of functionality at all?
Someone i know followed what you did on a barred s2.
It now connects to virgins network but she can no longer switch on Bluetooth.
It tries to start then Bluetooth flicks over to off again.
Looking in phone details reveal that Bluetooth address is listed as unavailable.
Everything else seems to work fine.

Quick update, my friend tells me virgin seems to have blocked the imei now.
I purchased the Samsung Galaxy S2 from someone and after a month the Sim card did not work, tried other sim card same and I have a feeling that the IMEI is Blocked and I would like to see how if anyone can. Unblock IMEI/ SIM
Cheers
You can't. There's almost always (99.99% of the time) a good reason for a phone being IMEI blocked. Call your carrier & sort it out with them.
Theres a thread about a bird getting a phone back from the police and someone got a barred imei working on vodafone.
The title was "..........came alive".So search for that.
Hey guys,
Well where to I begin. Well to start I have been trying to fix a Samsung Galaxy S3 since two days ago and I have had absolutely nothing but headaches for most of that time. My friend came to me and asked me to fix the phone. I fear that it is IMEI blocked by the network (It was on 3 for the UK and when I unlocked it it went to GiffGaff in the UK) but it had been working for about a year before this and I am not sure why it has been blocked now. The phone just keeps on saying "Not registered on network for the Sim card inserted in it for Giff Gaff)
I have tried to see if there was something wrong with the IMEI number but as far as I can see the phone has the right number with it.
I am wondering what else I can do because I have tried factory resetting it, using the EFS professional incase it had something to do with the EFS, though I don't think it does.
Can anyone point me in the right direction? Thanks a million.

yep mate phone defo blocked you will have to change imei to get it working again.
Changing IMEI is illegal and forbidden on XDA .
Google IMEI checker see if it registers as blocked .
Then go and read the faqs and guide or pay for a service repair .

Critical you read the first two posts .
Firstly this is my second post about this as I posted in the wrong area. (hopefully an admin deletes that thread)
Hey I have done some reading but I am a little confused.
I have a phone that will not call out to other numbers due to being locked,
I also have another 2 phones that will only use wifi. The sim card in and still not a detection.
This forum looks like the right place to help but I just don't really know what I'm looking for.
Could someone provide me with a little information about what I need to do with my 9300/9305 phones to get them back to normal.
My opinion on this is that these phones are blocked/locked and I need a program to fix these issues.
If they are imei blocked then no, you won't get any help as it is illegal. Contact the mobile network operator to reverse the blocking.
Three blocked phones is quite suspicious.

POST 2 network and EFS
Hi folks,
This is my first post so if I've done anything wrong please let me know. I think I'm experiencing quite a unique issue.
I have a Samsung Galaxy Nexus (Maguro) phone on O2-UK.
I'll try and summarise my issue
Currently I cannot make calls or send messages but can use 3g on the device.
When I put my girlfriends EE sim into the phone I can make calls and send texts
When I went to France with my O2 sim I could make calls and send texts
When I put my O2 sim into another device I can make calls and send texts
Whenever I try to make a call it states 'mobile network is unavailable' and when I try to connect to O2-UK in settings it states 'cannot connect at this time. please try again later'. The phone states emergency calls only but on the status bar it looks like it has a network connection and 3g can be used.
I've tried phoning O2 to setup the APN settings
It all started when I upgraded to CM12.1 from CM11. Although I have tried downgrading to the previous version and I am still having the same issue. I've tried wiping everything on the phone numerous times.
Is there anything else I can try, something I can wipe or a setting I can change?
Any help would be much appreciated!
If I can't sort it I'll grudgingly have to buy a new phone which is annoying because it only seems to have an issue with O2 in the UK
I had this when I upgraded from cm11 to cm13, all I did was turn on airplane mode for 10 seconds and switch it back on.
I wish it was that easy for me!
It seems that my phone has been blocked on my network (O2) since updating. Is there any way that an IMEI number can be involuntary changed during a root and installation of ROMs/radios?
I know this may be a very stupid question but my provider seems to think the IMEI number is strange, even though I purchased the phone from them in November 2011.
When I phone O2 their system says my IMEI number is different from when I type in *#06#.
Has anyone experienced this?

Hmmm, you stated that the card worked in other phones right? I am pretty sure you stated that other cards also worked so to be honest, this is something you have to phone them up seriously about.
Yes when I put my girlfriends EE sim into the phone it works fone. Also when I was in France my sim card worked fine, I'm guessing because it was using other networks.
It gets even stranger, when I type *#06# into my phone I get an IMEI number. I used an online website to check the status of the IMEI number and it stated that my Samsung Galaxy Nexus (which I've owned from new) is actually an iPhone....

I think we just found the source of our (well technically, your problem) problem. Now, do you have a nandroid backup or something that you are willing to restore to? I will look online for how to restore the imei.
