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.

Hi everyone
so today my tmobile galaxy s2 decides to not receive any signal from my carrier. In addition, the flight mode cannot be turned off.
Did some research and turns out my phone could be locked due to 3 reasons and the only possible explanation i can think of it is blacklisted due to "lost or stolen"
I bought this phone off craiglist.
When I thought all hope is lost and time to buy another phone.. i did a factory reset and wipe cache, and now my phone has signal again. So to all the experts out there.. what does my case mean??
My phone just wanted me to suffer today or this is a temp fix and tmobile will soon catch on and block my signal again??
THANK YOU everyonee
Based on your past posts (in the Vibrant section), it seems you are a T-Mobile USA user. In which case, your Galaxy SII is actually the SGH-T989, not the GT-I9100. You're in the wrong section.
SGH-T989 forum here.
EDIT: actually, since you got the thing off craigslist, maybe you DO have an i9100. Either way, check for your model number on the label under the battery.
perhaps re-insert the sim-card
even though carriers are able to deactivate the phone service for you i never heard of any carrier being remotely interested of offering that service to customers who lost their phone or even the police. the police would not even bother to take action for such a low value object

Recently I stumbled upon an article for US legislating a law that will force the carrier to deactivate signal reception for phone (like the one in EU) if the one is reported stolen by the police (I had a friend who bought a stolen phone and the police came knocking on his door). I know for a fact that "blacklisting" is done based on the IMEI number of the phone (which you can not alter with) so to be honest I don't have a clue what could be the problem/solution in your case.

unless it was blacklisted blocked based on IMEI and by fluke, when he updated the rom he corrupted his EFS folder.. Go into 'about phone' in settings. if the IMEI is listed and correct for the handset, and you have data and phone signal then your phone is not blocked for lost or stolen... More likely the phone has an intermitent fault hence why it was on sale on craigslist.... Use it, if the problem resurfaces come back on here...

I noted you quoted everyone else's reply but mine. ARE YOU SURE IT IS AN I9100 AND NOT AN SGH-T989?
EDIT to add: I should also note: if you are, indeed, a T-mobile USA user, and if it IS, in fact an I9100, then you will not ever get T-mobile's "4g" speeds with the phone. The I9100 doesn't have the required hardware antenna to receive one of the two necessary bands to get high speed mobile data on that network.
If it is an SGH-T989, on the other hand, then you are in the wrong forum. The T-mobile USA Galaxy SII has completely different hardware from the GT-I9100, and thus has a separate forum.
[Q] "Can't connect right now. Try again later." or equivalent in stock, CM9 and CM10
Hi folks! Needing some help, please.
I've googled my problem a lot but couldn't find any working solution. Below is the detailed history.
I have recently bought a Samsung Galaxy S3 GT-i9300, cut my previous SIM, and used it for about four weeks with no problems. During this time, I rooted my phone, backed up the stock ROM, installed CM9 and afterwards CM10.
About a week ago, while using CM10, I switched off airplane mode after about nine hours and the signal power meter was empty. All the services related to my carrier (SMS, 3G, calls) were inoperative. I rebooted the phone, tried removing and reinserting the SIM, with no success.
I tried flashing the previous backups, also with no success, but noticed that while using the stock rom, the signal meter was full. This prompted me to access "Settings > Wireless (...) > More... > Mobile Networks > Network Operators", where to my surprise all the available carriers were listed. I did the same check in the rural area of my town, where I know my carrier does not work, and the cellphone correctly detected only the other three carriers.
These symptoms led me to believe that my cut sim could be the problem. I got a microsim from my carrier, but the problem persisted.
After this, I assumed the problem was software related, googled it and found some recommendations:
Complete wipe and backup restoration: this was not successful with stock, CM9 and CM10.
Complete wipe and stock ROM re-installation with Odin: also not successful.
Modem flashing with Odin: also not successful.
Firmware flashing with KIES: I put the cellphone in download mode and made the firmware recovery procedure from KIES. Also not successful.
Restoration of efs folder and IMEI related issues: I did not have backup of this folder, but the symptoms related to the problem in the posts I found always included the absence of IMEI. When I type *#06# in my phone, I can correctly see my IMEI, so I discarded this possibility. My carrier also informed me that my IMEI is not blacklisted.
I thought of getting a new microsim to rule out any SIM related issues, but still haven't done it.
Information regarding my phone:
Phone model: GT-i9300
Baseband version: I9300UBLG2
Firmware vesion when on stock (from KIES): PDA:LJ1 / PHONE:LI2 / CSC:LJ2 (ZTO)
Could someone please help me? I still have not tried the EFS folder troubleshooting, but the procedures I found were related to problems that did not show the same symptoms as mine. Do anyone have any suggestion? Please tell me if any more information is needed.
Thanks!
Why not just get a micro Sim to begin with....they don't cost anything and it saves a whole lot of hassle. My guess is the sim reader is damaged....IF and WHEN you decide to get a new micro sim, if it doesn't work then that could be the only cause and the service centre your only option. Seriously dude, next time to save yourself hassle....go an get a micro sim from your carrier, I wouldn't even think about hacking away at an old sim because I can't be bothered to walk to a Vodafone shop.

I have just come back from the carrier store, where I got a new SIM, and the issue persists. I also double-checked any IMEI blocking or problems with my services, and everything is ok.
Coincidentally, a Samsung consultant was around. He checked my phone and talked to Samsung tech support describing the issue.
They do not think it is related to the cutting of the SIM card for two reasons, the first being the ability to locate the carriers, the second being the fact that a visual inspection of the slot and the scratch marks on the SIM card do not indicate a broken or bent contact.
Obviously, he recommended that I send my phone to an authorized Samsung service center for maintenance.
I am still inclined to think it is a software related issue. I will, of course, send my phone to Samsung if it is case, but in the meantime I would like to try new procedures to bring back my phone's ability to connect to my carrier.
Suggestions?
Thanks in advance!
An additional information:
I tried checking my sim through some apps, to confirm there is no damage in the contacts. GalaxSim Unlock is able to detect my sim and correctly show my phone status as unlocked.
Any suggestions on tests?

Hi!
I bought S939(not completely new), which from what I understand is not a device that's created for the European market. In order to make it function, I believe that the device was rooted\modified. Now, I can perfectly use it to go on the internet, make photos ecc, but when I put my SIM , I'm unable to "catch" the network of my provider. A message "Can't connect right now. Try again later." appears. I can save numbers on the SIM, for example, but unable to register on the network.
Also on the main screen, I can see writter "Invalid IMEI".
Thanks!
no backup imei ? try flash stock, should repare imei (i think) - but i have phone with mediatek and cant flash (get error)

Inactive sim?
Beamed in by telepathy.
First of all, I'm in the US. I bought the Samsung Galaxy S II GT-I9100 (I'm in the right forum, yes?) off of ebay.
From what I remember, when I received it, it had some weird ROM that I had never heard of and can't remember the name of, along with clockworkmod recovery already installed.
I put cyanogenmod 9.1.0 on it via: [cyanogenmod's site, model galaxys2 cm9.1.0] (I can't post links yet, so I had to remove all of them).
I was using it mainly for development for a while, so I never tried to activate it on a network using a sim card, but recently I tried to do that with StraightTalk (using an AT&T sim). Nothing happened. I rebooted my phone multiple times, took the battery out, reseated the sim card multiple times, etc. Nothing is any different than before I put the sim card in (except the messages about "No sim card installed" have gone away). And in the settings, it shows that it can read the phone number from the sim. I actually talked to their support for a while and they couldn't figure out what was wrong. I tried the sim in 2 other phones and it works fine on those.
I thought maybe the problem was cyanogenmod 9, so I tried installing cyanogenmod 10 nightlies made specifically for this model from: [cyanogen's site, model i9100 cm 10 nightlies] . Same thing with that. No network connection, emergency call only, etc. I've gone through the settings, trying to change things throughout. I've tried to force-connect to AT&T's network via the Mobile network settings -> Network operators menu, but it just says it can't connect to that network. When I tried to connect to TMobile's network, it said this sim card did not allow a connection to that network.
I wanted to double check to make sure the sim was actually unlocked, but none of the magic codes ( [cduu wordpress galaxy s2 secret codes] ) work except to display the IMEI. I've checked a couple online databases to make sure my IMEI is not blacklisted, and both said it was not blacklisted.
Getting pretty much nowhere, I wanted to return it to stock, but when I read up on it, I could not figure out what to do in order to do that. I'm not very experienced with the GS II; my personal phone is the galaxy nexus. After reading up on it, there's about 100 different versions of "stock" for this phone, depending upon what country/language. I don't know where this phone is from, but the only booklet it came with was in French.
I did find the sammobile released firmware versions for jelly bean and ice cream sandwich (I9100XXLSJ_I9100OXXLS1_OXX.zip and I9100XXLPH.zip) from [sammobile's site] . I don't even know if these are technically stock though. The only one I tried to flash was the ice cream sandwich one; the jelly bean one is still downloading. When I tried to flash the ice cream sandwich one using Odin3 v1.85, it just failed. Didn't harm any of the software that was on there, so I'm guessing it found that it wasn't the right version for my hardware?
So after all this work, I'm coming up empty.
Is there anything else I can do to try to troubleshoot why I have no cell network connection at all?
Should I try to flash back to stock and if so, can anyone tell me what english-language version of firmware/software I have to flash/install to my phone to get it back to stock?
Can I provide any more information to help?
Thanks for the time.
Since you have verified that the sim card is working properly.
Then the issue is with the phone,did you check with the provider if the imei of the phone is valid or not. It maybe a blocked device because it was reported lost or stolen previously.

I only checked in a couple online databases and they both said it was not blacklisted. I found the IMEI issuer at imei-number .com though, and it says it was issued by BABT (British Approvals Board of Telecommunications). Is that who I would contact? I don't know how I would contact them and get a response. Other than that I don't know what carrier the phone was used under before.
If it is not blacklisted
It maybe a hardware issue in that one pins for the sim card is not making contact properly. You may need to take the phone apart to see if there is an issue with sim connection.
Would it be able to read its phone number from the sim if a pin wasn't making connection?
Under About Phone -> Status, Network is Unknown, Signal strength is -111 dBm 1 asu, Mobile network type is HSDPA:9, and the phone number is listed correctly.
Oh, one thing I didn't mention is that the device ID from "adb devices" shows up as 0123456789ABCDEF.
And I just noticed in the About Phone -> Status menu, the Serial number is "unknown." Is there something in my ROM or something that is blocking or has erased the serial number or device ID?
Any ideas?
I'm probably going to have to buy a new phone for development today, so if anyone had something to try before then, it'd be really appreciated.
I know this is an old thread. But spent so many days reading all those stuffs. Finally contacted samsung service centre and they says they can't repair my phone since its not manufactured in my country. Tried repairs like '' GSII repair'' and lots of other. Am not sure what I did. Deleted efs folder and copied, pasted. Nv files restarted. But of know use. When I tried inserting another network simcard(my friends) . The imei didn't change. But I was able to make phone calls and 3g. Bought a new sim of the same network. But I couldn't use it to make calls. It shows network not registered(like my previous carrier). The only thing I am able to do is I can use 3g. And I am typing from this same phone. Thank you for reading this..

how to change imei number samsung i think you will get some good vids
OP - take it to a local mobile repair shop, most should be able to fix this fairly cheaply (I can get it done for ~AUD$30).
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.
