So I had all updates blocked on my Note 7. I am 100% sure that no update was pushed to it. There are no pop-up messages and it charges to 100%.
It stopped working on Bell's network but the SIM card works fine in other phones. I called Bell and they checked my IMEI and confirmed that it wasn't blocked.
WTF.... Is Bell lying ? I know there was no update pushed to it because of the blocks I put in place. Wi-Fi/Bluetooth both work and it charges fine.
So it has to be an IMEI block right ? My guess, Samsung told Bell to block them and Bell is simply lying. The guy literally went "oh well it must be a hardware fault". Yeah right....Hardware fault on the day they block them off...What a coincidence....
There is no reason a random CSR would even be able to check this. Some tech fed the results of a database query on one table into another table, and your IMEI was blocked.

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...

you will be surprised how well the carriers are informed and trying to stop thievery. Orange and Tmobile are teaming up to share their database

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.
i've orange uk line. been to abroad for 4 weeks, lost my simcard there, got back to uk and called orange.they sent me a replacement but it's been 1 day still no signal.when i put my simcard to another phone it works fine.when i put someone else's working simcard to my phone, it doesn't have a signal.if i check about section on the phone, it says i'm connected to orange signal strength is high but no service.what do you think the problem is?
IMEI blocked or account at your carrier's end not setup properly (or at all ?) perhaps. Given you lost your sim/had to get a replacement, I'm betting they've still got a block on your account as a result of this.
Call your carrier to check this. Not much point troubleshooting this only to find this is the problem later. This is the most obvious thing it could be in the first instance so clarify this with them.
you're definitely right.i called the carrier and they said they'd blocked my phone either.thanks for help.
No probs. Hope you get it sorted out soon ;-)
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?

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.
OK this is my first post and it's a weird one. I've always known phones to be useless without a SIM card except for emergency calls. Well today I purchased an S4 on Craigslist. As I was bringing it home, it started to ring. I didn't answer it and shortly after I received a text. There was no SIM in it so I thought it was weird but left it alone.
When I got home, I did a factory reset, put in my old SIM card and activated it to my number. Everything went well - received texts normally, emails worked great, called my husband's phone and worked great until I looked at his phone and saw that the number that popped up wasn't mine, it was the old number. Tried calling my phone with his and went straight to vmail.
Seems like everything activated correctly except for the phone function. Called Verizon and the rep thought it was odd as well since texts went through, but could not figure it out. The rep said the phone is probably tampered with, but I've never heard of anything that could make phone calls without a SIM or wifi.*I reactivated my old phone and left the S4 with no SIM and it's still able to make/receive phone calls!! Weird!
All IMEI numbers match, physical and in About Phone even on box. Phone is not rooted according to Root checker.
Please someone tell me what this is so I can just can undo it and activate my number to the new phone.Thanks
Maybe Verizon or an emergency service was trying to call you... They don't need a sim for that.
The old phone issue is normal every time they port a number or switch a number they [email protected]#$ it up I've had it happen a couple times it on their end not yours

The Sim is only for LTE service, you use built in CDMA radios for calling.
I honestly don't know about the number issue, take it to a corporate Verizon store (the private stores only care about sales not customer service) to have them properly activate it.

Sounds like the phone is set to nv-only mode. The vzw s4 is fully operational in this mode but it won't pull your phone info from the sim card.
This is the mode we put the phone in when flashing to carriers like page plus, selectel, etc.
If you want, you can PM me the meid of the device and/or the phone number the calls are being placed with. I'll check to see if it's an active page plus account.
I have an lg k8+ model x210ulm that i want to use with cricket. The phone is fully unlocked and will accept any sim from any carrier but has an odd behaviour that wont let me use my own sim.
I bought a feesh sim from cricket and when i put it in and set it up it will register with crickets apn and mobile network settibg. I get data and it shows up in the about network as connected and working. It shows cricket carrier in notificstion and i can get texts and even voice mail. But ........
I cannot use the dialer. Upon connection there is no error toast or anything it just imnedistely hangs up.
I can use my wifes my sons or my friends sims in the phone and after a reboot works perfectly. But when i put mine in it stops.
Also my sim works fine in any other unlocked device or cricket device.
Any clue as to wth is going on
Ok so after talking to lg and really that was frustrating. Why because the rep told me it the phone was carrier locked to us cellular which i knew it wasnt because its advertised as being unlocked and well us cellular put up an advert a few years ago stating that all thier phones are unlocked.
So after that i went ahead and talked to a rep at us cellular who assured me it was unlocked and checked the imei for me and sent me link to the advert about thier phones being unlocked.
Back to lg and got another rep this time who knew a lil about something but not much. Could not tell me any thing though.
Now back to cricket where we tested my girlfriends sim in my phone to which it worked and mine in her phone to which it worked. We put the sims in my aristo 2 and fortune 2 and both sims worked. But when i put my sim back in my my k8+(2018) once again every thing works fine but you cannot make or recieve phone calls.
We also tested the voice mail app and and thier what qualifies as a carrier app and it registers. The sim registers in about phone shows service and is connected. Shows the phone number every thing works.
Just not the phone Dialer app
So is there any one out there at all that has had an issue like this before. Any one that can help me figure out what the problem is. This is so crazy that my sim wont work and every one elses will.
Could it be something i did using dialer codes? Any cLues at akl
So here we are months later and im still having sim issues with my k8+ ulm. I ended up buying a brand new device and i tried my provisioned sim card with it not working but literally every other sim card works fine.
I have switched from cricket to assist wireless now who is run or what ever by sprint and i can get the sim card to work for a couple days before switching it to another phone but the main issue is that i get a error popup stating that the sim card has locked and that i need to power cycle and call customer service.
But i made a ton of changes by adding all the system apps from sprint including sprinthiddenmenu and any other apk that was on the tribute dynasty they came from. I also went through the file system and made any prop changes or any thing else that was needed to enable sprint.
At this point id flash a sprint modem but i cant find a cv1 device provisioned under sprint
