[Q] help with GT N7000 00499 imei problem?

Hello
new on here, and hoping someone can point me in the right direction please - I think my phone has developed an issue with it's IMEI, it will no longer register on any networks to make calls or send texts, although 3g internet works. It is a galaxy Note GT N7000 on android 4.1.2 and seems to have a generic 00499 IMEI number. I live in the UK
I've had the phone since new with my contract. I wondered if something happened after the last android update, or whether it has developed another issue. I didn't want to renew my contract, so when it expired I started using a PAYG SIM, and that has been fine for the last 3 weeks so I don't think my phone is locked. The SIM works in other phones so there is credit and network coverage.
It is unmodified, and I have never rooted the device, or installed any custom software. I read online that that automatic updates can sometimes cause Galaxy phones problems resulting in a default IMEI number. As I have only installed automatic updates through KIES and via my previous mobile network, I wondered if this has caused a preoblem, of if the phone is blocked!?
I would send it for repair but I don't live near any repairs shops :crying: I don't want to change the IMEI just restore it to what is on the label if that will fix the 'not registered on network' problem.
If it means buying a new mobile, then I'm happy to learn something new to try to repair it....just where to start?
thanks in advance :fingers-crossed:

Can't call anymore since the motherboard swap

Hallo everyone,
What's up: my Nexus 5 can't make any type of calls.
The story behind: in march the memory chip of my Nexus 5 died, so I let it repair from the official LG support (it was still under guarantee). They changed the whole Motherboard and send me it back. At the same time, I received the new SIM card from my mobile network operator (o2 Germany) because I moved from prepaid to contract, but I still keeped my number.
Since the first day with the repaired Nexus and the new SIM, the LTE worked without problem and I could surf, but I couldn't make a single call. I talkd with the o2 Germany support, and they toldt me that It could have been a problem related to the number porting. After a few weeks the porting was officially completed, but I couldn't still make any call. Then after many weeks and many support calls, I had a so simple Idea...just let's test my o2 SIM on my old Smartphone (an HTC Desire)...and finally I could make a call! So I'm sure that the problem doen't lies on the operator or the SIM.
What's happen exactly with the Nexus 5 and the o2 SIM (here the Video): the LTE Network is full available, I call a number and appears "Dialing" (sometimes the screen turns black without any reason until I press the power button, but not this time), after seconds of absolute no sounds it shows the error "Cellular network not available". Of course I tried to call different numbers, but the problem persist and it still remains, even if I use another SIM from another operator.
I'm really concerned that maybe the problem lies on the Nexus 5 hardware, maybe the antenna, after a bad repair...but that's just what I suppose.
I'm looking forward for your opinions and support, thanks a lot!

Have you taken any steps to troubleshoot?
Seems the issue is the N5, as the SIM is working, but it is unclear where the problem lies. Have you checked the APNs, do they match the ones on HTC device? Maybe try reflashing factory image? Factory reset?
You said LTE is working, so it is not antenna, I think it is a software issue. Start by checking APN.

Thanks for your answer, I will consider the antenna as functional
I have been checking the APN Settings with the same o2 SIM on the two different devices (Nexus 5 and HTC Desire), they are identical, but the Nexus 5 got some extra settings.
As usual, with the Nexus 5 I can't call, but if I move the SIM on the HTC Desire it does. Just using the same dafault APN configuration. Those are the suggested configuration on the official o2 Website, but I would just stick with the default ones that already works (on Desire).
Any suggestion?
I would do a factory reset just a last choice, because I got tons of apps and data that needs time to be reinstalled.

Another info: the LTE Network on the Nexus 5 sometimes disappears, and then appears again.

Bump, any Idea about this problem and how I could fix it?

Hallo, I'm asking again for your support :angel:
those last weeks I couldn't get rid of the problem with the calls, and I'm still clueless about how I can fix it. At the end of the month the 2 years guarantee expires, so I need to hurry up.
Summary: SMS sometimes comes later als expected, sometimes LTE Data doen't work, most of the times I can't make calls.
What I have already done:
- already moved my main SIM (o2 Network) from my Nexus 5 on an old device, and there I have no problems at all, and I can make all the calls that I want.
- already checked the APNs, they are all on defaults settings and are ok.
- already tryed to use a fully functional SIM from another network operator (TIM Italy) on my Nexus 5, even if the Network is fully available I can't make any single call.
At this point, I'm pretty sure, that the o2 SIM and the o2 Network itself works fine.
Today I have done a factory reset after a full backup on my Nexus 5. With all default an no extra app there's no improvement at all, call function works only a few times, most of the times I got the Network but the call function doesn't work properly... here just a frash Video about it:
https://drive.google.com/file/d/0B0yEcZCOozgkdmdjZWs0bkdIUnc/view?usp=sharing
After this try the LTE Network has disappeard (here a Foto) coming back only later as EDGE Network.
Could be maybe that after the Nexus 5 repair in march, the Device was assembled incorrectly and the Antenna have an unsteady contact?

Isn't the IMEI stored on the motherboard? If so, its possible you got a motherboard with a blacklisted IMEI.

I don't think that the officially LG Support (that replaced my Nexus 5 Motherboard im march) would use Motherboards with blacklisted IMEIs. Even if my motherboard had a blacklisted IMEI, then I shouln't be able to make any single call, but that's not what happens, because I can still and receive calls sometimes.

Well then I think you already know the answer. The warranty repair wasn't successful. You've eliminated everything else except the phone, and it used to work before, correct?

Yes, sadly seems that the problem lies on the unseccessful repair. Could you reformulate your last sentence/question? I didn't understand what you you mean

Is your phone switching to 3G while calling ? Because afaik, 4G can't be used to call someone.
So I suggest you to force your phone to stay in 3G and try making a call.

When I try to make a call with the LTE (4G, with full coverage showed), the call doesn't succeed (look at the last Video that I posted) and just after this the Network disappears and shows "Mobile Network Not Available" (but this doensn't happen always), then a few second later the LTE is available again.
When I move from LTE to 3G there's no Network available, and the call just doens't work. Same with 2G.

Update: I received back from the LG repairing my Nexus 5. In order to fix the problem with the calls, the entire motherboard was swapped. I didn't received more detailed informations about this fix, but right now it works again greatly.

Did you flash all 4 parts of the new ROM with ODIN?
BL + AP + CP + HOME_CSC
Then factory reset afterwards?

Did i made some king of big mess by not choosing home_csc but only csc the first and second time ...

Try the latest BTU from samfirm tool (BPJE)
http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Released today, a lot newer than the one you originally tried
If that doesn't work, I'm not sure

I am downloading it right now. I will try it later and will write. I suppose i have to choose home_csc right ?
I uploaded some attachment from phone info if that could make any change for the solution ...

Try both if one doesn't work
There is also smart switch / KIES emergency firmware recovery you could try
But tbh if ODIN successfully flashes the new ROM and it boots without being able to make calls, something else is wrong IMO
Do you have a network signal for your carrier?
Could the phones IMEI have been blacklisted?
Call up the carrier and ask if it has been blacklisted, if the previous owner reported it stolen they might have had it locked / blacklisted, which would stop it from working on any network

Tried with odin , tried with smartswitch firmware and still cant make/recieve calls.
It cant be blacklisted because when i got it everything worked perfectly until i changed the software. She have internet ( mobile internet ) so the sim card must work someway ... but she cant make/recieve calls

IMEI blocking only bars the GSM functions of a phone (calls and SMS texts)
Mobile data (3G/4G) and wifi services will still work.
Looks like your IMEI got blocked

Apparently it is blacklisted .... Sooooo is there any way to pay or any other way to unblacklisted
We bought the phone in our home country while we were on vacation ( Bulgaria ) and then changed the software and we went back to UK. So the phone is working in Bulgaria but not working in UK
Any ideas...
Atleast we know the problem now ..

Your main post says you bought it on Virgin UK, how if it was in Bulgaria?
And you said you bought it a few days ago, now you say when you were on holiday over there
No, once it's blacklisted it's dead afaik, people steal phones, the real owner reports it stolen, it gets blocked
And it wouldn't be blocked on UK networks if it was originally from Bulgaria either afaik - stolen UK phone = blocked on UK networks
Moral of the story, don't steal phones

I have the payment for the phone so i didnt steal it
Long story short... I bought the phone on 24.10 in Bulgaria ( It is Virgin UK but bought it in bulgarian website. The phone worked with bulgarian sim and changed the software with no bloatware ) , she came on 26.10 to visit me ( vacation from university ). I gave her the phone as a present and it worked great in Bulgaria but only on wi-fi ( she didn have roaming so we never placed her UK sim ). She went back to England on 01.11 and placed her UK sim-card and the phone didnt work. That why i assumed the problem could be from changing software but all along it was blacklisted ... ( Altought it is not blacklisted in Bulgaria ).
So if there is nothing we can do i guess i will have to resell the phone in Bulgaria and buy her a new one.

Your main post says "everything worked fine , could make and recieve calls and so on"
Now you say you only used WiFi?
Anyway, the phone was obviously reported as stolen, it was a UK phone being sold in Bulgaria, there's alarm number 1, so most likely the seller you bought it from had a hand in that if you have payment receipts, so contact them, request refund
If you sell it on, make sure you list it as UK IMEI blocked too

Indeed when i bought it i tried it with my sim-card and i could make calls ( after all i am buying a second hand phone , i checked everything ).
I will try to request a refund but i dont believe that will work..
Anyway i think we can close the post if there is nothing else we can do.
Thank you for all the help!

Question T-Mobile A32 With AT&T Sim Card Won't Make or Receive Calls

Before I get on hold with AT&T tech support, I wanted to ask the experts if anyone else has had this issue.
I bought my new A32 about a month ago. It was branded for T-Mobile, but was unlocked already.
In the past, I just put my AT&T sim card in the new phone and it was ready to go (I don't mind the T-Mobile start screen).
It worked fine for a couple of weeks, then T-Mobile sent out an update and it stopped receiving texts. AT&T put in a new sim card, and that fixed the text problem, but now it won't make or accept phone calls. Calls go right to voice mail. When I try to dial a number, it just disconnects immediately.
Anyone have any idea of what could be wrong?
Thanks.

You bought an unlocked phone for a different carrier, unlocked by a third party, and updated it.

the phone can have some issues if...
1. the software version running is different (each carriers may have different versions they approved and pushed to update for their customers, hence not supporting some versions)
2. If you have unlocked and the carrier is some minor name carrier and not the main ATT then the phone may not be supported by them.
You should backup all your data to either Google or Samsung account or whatever option is shown... then ask to have the device flashed with the latest market software version from ATT. Hope this helps.

I have the same problem. Acquired a NIB T-mobile Samsung A32 that is confirmed unlocked but doesn't work on PuretalkUSA when it came to calling or receiving calls. Texting and websurfing works but call get immediately terminated and calls made to the phone go automatically to VM. I spent three hours on the phone with Puretalk tech to make sure the settings were correct. The tech had me attempt to update the carrier configuration version to no avail. It refused to update and remained at version 0.0.0. I then stuck an T-mobile sim in the phone and noticed that the carrier config version change to some series that I currently do not recall. However, I still could not make or receive calls. I then purchased a prepaid ATT sim and stuck it in the phone. The carrier config version changed back to 0.0.0 but I was able to make and receive calls. I'm putting one more call in to puretalk to make sure I've tried everything before giving up on the phone.
I recommend that you check this guy's video on youtube. He seems to be on to something:

No Cellular Service

Hi,
I bought the phone about a year ago, secondhand from the local ecommerce. The phone still had android 10 so I updated it to 11. It was fine, until a few months later when it started to lose cell service. It could be solved by turning airplane mode on-off or restarting the device back then, but now I can't get service at all.
Pixels isn't officially sold in Indonesia, and it was most likely bought in Japan. I can see the "osaifu keitai" app but also a load of Verizon-related apps/activities. I'm not sure if this is a locked phone, not only because I've unlocked the bootloader easily (like a regular phone), but I also only have "Sim 1 not allowed" or "Phone not allowed for voice" notifications instead of "Contact Verizon" or something like that.
Here's the thing though, I can't get service with almost all major carriers here (Telkomsel, Indosat, XL), but I can with Smartfren, even surf the internet with LTE, but still can't make a call or dial USSD codes. I have done this guide, also manually select a network from settings, 4636, even locked freq band with Network Signal Guru, still no luck and I'm out of ideas now. Whether it's the official build from Google or rooted LineageOS (what I use now), it's always the same.
Please help. Thanks in advance.

Hope I'm not too late to reply.
Hi, I'm currently using Pixel 3a XL that i bought around 4 months ago, "blackmarket" phone is banned in Indonesia so this tend to happen. Government blocks the "blackmarket" phone's IMEI because the IMEI in our phone is made by "injection" or sort (yeah, your provider is connected to your IMEI code, i don't know how it works) and that is illegal because we don't pay tax for the phone. In my experience of buying "blackmarket" phone, i had to send my IMEI image to the seller as for "warranty" purpose, if that didn't happen to you when you were buying the phone, it's better to use third party store to restore/inject new IMEI, don't forget to move/backup your data before doing it.
