S8 G950F wont get signal - not blacklisted IMEI: NG - Samsung Galaxy S8 Questions and Answers

hi all
i have a uk model s8 on the o2 network which was originally locked to o2.
so i took it the local market to get it unlocked which the market trader did and it accepted another uk sim
but wont connect to any network now. states emergency calls only, even with my original o2 sim.
i cant even search for any networks. when you try to search for networks by choosing the phone option, nothing happens, just states not available at this time. same thing when you try to choose manual or automatic search.
it accepts any sim now but wont connect to any network.
i thought it may have been barred even though i bought it 2nd hand and had it over 8 months so i checked imei on the net and it comes up clean. so not barred.
he couldnt also understand why you cannot search network, why this option cannot be selected.
so i come on this forum for some help, and a member did help me and got it working by flashing something to it via remote team viewer but after a few hours it stopped catching a signal because i downloaded an app onto it to hide root which worked but caused the phone to loose the signal again. and then when i contacted the member, he refused to do it again.
i pleaded with him to flash again or do whatever he did but after days of waiting without a phone he was not available to help. so please can anyone help and tell me what he did so i can fix my phone.
i know from users on here, you can have root hiding apps running on an s8 and still be able to perfom the fix to the problem on my phone.
i know it has something to do with imei not being registered on phone and it showing a NG next to imei.
any help or guidance would be appreciated
regards,
Margaret acey

don't O2 unlock phones for you free of charge? That is how it used to be when I was last in UK.
I really wouldn't trust anyone to remotely download/fix phone, they could do all sorts, hopefully you got a good guy but the fact they won't do it again seems suss to me.
Have you done this,
https://www.technobezz.com/fix-samsung-galaxymobile-network-available/
I suggest you flash stock o2 rom and take it to O2 to unlock phone, this will" clean" your phone so if the helpull member installed anything he shouldn't have it'll be wiped. Also check white o2 if your data etc has being used by someone else ie cloned your phone. (but there may be some other issue as the trader couldn't search for a network)

Thsnks for the response.
Its not locked anymore. As it accepts all sims which it didn't anymore.
This has something to do with the imei not been registered.
The imei status is NG when it should be OK.

Problem connecting to Vodafone on SPV M3100

Firstly, hello everyone.
I recently bought the Orange SPV M3100 on eBay, and can not for the life of me get it to connect to Vodafone with my contract SIM.
So far I have:
-Sim unlocked and superCID'd the phone.
-Installed WM6 (via CUSTEL).
-Tried 3 different Radio versions.
-Attempted to install Vodafones official update (which failed for reasons unknown).
-Played around with just about all network settings.
Basically, the device acts as if it's trying to connect to the network, but doesn't (PC speakers pick up inteference etc).
With automatic network selection it just doesn't do anything.
With manual network selection it gives all four big UK providers (allowing for signal - I live in the North York Moors) including Vodafone, but won't connect to any of them.
If I click 'set networks' I get a HUGE list of providers. Vodafone UK (if it appears at all, for some reason O2 and TMobile seem to appear on the list more often) is nearly always unchecked at the bottom. Checking it doesn't fix the problem. When I go back there later it has sometimes lost that setting and Vodafone is unchecked at the bottom again.
I should probably mention that any setting I change here results in a 2 minute "Sending new settings to the network", and on a couple of occasions has caused it to crash.
If I go onto band settings, originally they were both set to auto. Infact, I've just gone onto it as I type, and they have gone back to auto. Before it had got stuck on GSM/UMTS band type 'GSM(900+1800)+UMTS(2100)' (gave an error message unable to change band etc if I tried to change it to anything else). I cannot change the network type or GSM band otherwise without the same error message appearing.
So anyway, as you can see I've gone through a lot and read a lot unlike your typical n00b, and my prospects with this new phone are bleak.
Can anyone help me or suggest anything else that could get this phone onto Vodafone?
I have a worrying thought that this phone could have originally been half-inched (the eBay seller seemed a tad on the dodgy side), been reported, and is now serial-blocked from UK networks, if that's possible?
[edit] I don't know if they are or can be serial blocked, but in which case, assuming you trust and sympathise with my story, is it possible to hack & change the serial number?
Sounds possible that its been blocked. Yes there is a way but you probably won't find any help on this site to do it as it is illegal. Thats not to say you can't search the site, you may find something that may help... Search is your friend...
Cheers...
Yeah reading into the problem reveals a possible 'IMEI' block.
Time to contact the ebay seller I think.
Have spotted an obvious hole in my theory:
The thing came in it's original box (s/n sticker confirmed) with all manuals and accessories.
So back to original problems; is there anything else I have missed?
[edit]
Phone is unblocked according to http://www.amta.org.au/default.asp?Page=405.
So unless they're wrong, why can't I connect to Vodafone and what else can I try?
did you try *#06# on the phone to be sure the S/N on the stickers and phone is the same as the actual phone S/N?
Yes, they are.
Would Vodafone be of any help on this issue?
Depends if they supply that model of phone.
Do you have a network configurator app cooked into the rom you are using or are you using a stock rom?
Might be an idea to look for a network configurator cab if you're using the stock rom and see if that helps. Also if you are using a stock rom, and its not setup for vodaphone, it MAY (don't quote me on this) be affecting the network settings and making it incompatable with the carrier you want.
Just a thought...
I'd also try to run the sim unlock app again, just remember it has to be the SPL that was supplied with the sim/cid unlock tool. Make sure you install Hard SPL V7 back after checking this...
vodaphone will help you if you ring them up using a the sim card in a working phone and ask them to check if its imei is blocked, they do it totaly free of charge.. had to do this with a viewty i bought from a work buddy shorty before he forgot to tell me he did not pay the contract bill and t-mobile blocked it. well annoyed, but they told me it was reported Lost or stolen.
found a few places on the net that offer a check for £10 sod em lol
luckly got me cash back selling it for parts hehe
What a bloody carry on!
Vodafone told me it was blacklisted; reported stolen.
The eBay member is highly upset at being called a theif and very convincingly tells me otherwise (I'm 90% sure I can believe his story, and feel bad for my accusation).
Orange (of whom I'm not even a customer) then tell me "I'm sorry it's blacklisted for an unknown reason ... <click-click> ... there you go sir I've removed it from the blacklist!"
Well, if it starts working again in the next 48 hours I couldn't give a monkeys what's gone on. I just want the bugger to work!
the only reason that a phone would be blocked is if it was reported.......have you tried another sim from o2 or orange etc.
the question has been asked before about imei changing and as you know its illegal,but can be done so if all else fails search elsewhere,not here, i would suggest that unblocking a phone is never likely to be an achievable goal.the networks are not known for their magninimity

"Not registered on network" "No Service"

Ok got this phone but it wont ring or recive calls ! .
After putting in my SIM card, entering my PIN code it still says no service. When you try and make a call it says "Not registered on network".
It was on T Mobile which I have had it unlocked via eBay. I got past the Google registration page by entering APN settings for my SIM card (O2).
Now I can user the browser and market etc but no calls.
I have done everything in THIS thread and think I have flashed it with
JFv1.43 RC9. (When I say think it seemed to flash but I cant see any difference so not sure if it worked).
Does anyone know how I can get the phone to work?
Thanks for your time
i have been in this same situation for about 3 weeks and after spending countless hours on phone and at store with tmobile 3 replacement phone 5 sim cards and a new number they close my account and reopened it this was just tonight so i am testing it out so far i have lost servie twice within 3 hours restarted my phone both times and regained service so im not sure if it is completely fixd just yet
Its really annoying such a simple thing. When I try to manually select teh operator in settings it says "Your SIM dosnt allow connections to this network".
I tried an orange SIM card and for some reason it puts the phone in airoplane mode and wont come out :s
Any ideas would be appreciated.
Anyone got any ideas on what could be causing this ?
Thanks
same boat
man I'm telling you that's been happening to me. except I upgrade to ION and then reverted back to haykuro's 6.0r1. everythig that;s happened to this guy has been affecting me
No service
I also have a problem with my G1. Bought it from my local polish netwerk (Era) and the phone works OK however, from time to time it looses the connection to network and it needs a reset in order to login to network again. Don't remember if it happened before they released the software which supported polish language. So what do you recon is it a hardware problem or did those useless local IT guys screwed sth up while translating android??
hi i have he same problem stuck in airoplane mode and no service has anyone found a fix yet????
I´m yet another user with the same problem. For a few hours yesterday I suddenly had service, but it stopped working in the evening again.
Any solution?
A similar problem. Tell me what to do. Thank you.

I just bought a fido sim card and I get the msg: "cannot register on this network. choose another network, or disconnect your data connection and try again" when i try to manually connect to the network. I have using this phone with at least two sim cards back in my outcry and i bought it independently from my previous network from an eshop in Ireland..
Any thoughts? Could be the ROM and radio installed?

[Network] loss of connection on Orange Network, need help

Hi there,
I am confronted with a big issue which affects my ability to place or even receive calls: I cannot connect my HTC HD on the Orange Network anymore.
Two weeks ago I was on the road using TomTom and suddenly Windows Mobile told me that the distant server was disconnected and that I was not connect to the network anymore. Each time I am trying to get a connection, I can see that the mobile detects a network, tries to register (I even can see the Edge icon and some network bars) but always fall back to the 'not connected' icon.
The weird thing is that the mobile detects all the networks it is intended to: Orange, Bouygues and SFR (the three main operators).
Since that day, I have tried everything to re connect the mobile on Orange network but nothing was successfull:
- many and many reboots of the mobile,
- I have suppressed the Orange network connection in the connection wizard and then re created it.
- I have switched the network connection to manual and tried to connect manually: as for auto mode, it displays the following message:
"cannot connect to the selected network. Choose another network or stop you data connection and try again"
- I have switched the band mode from auto to "GSM (900+1800)"
- I have done hard resets
- I have changed the ROM two times: the first one for an up to date Mia and the second time for a Rhodyum 1.1 (the one I am using now).
- I have called the hotline to check if the problem is coming from their devices ; apparently not the case
- I have put my SIM card on another mobile and its working. A different SIM on my HD is not working. I even have changed my SIM card !
I am really desperate now because I do not know where the problem could come from. Should I do something else ? How can I be sure that it comes from my mobile ?
Thank you for your help
Yesterday evening, I have tried to restore stock SPL1.14; It did not work either
Nobody can help me or just give me clues to solve the issue ?
What is your SN? Is a 84x? See here: http://forum.xda-developers.com/showthread.php?t=476139 could be an RMA candidate, read the thred
OK, here's the short answer:
your phone's a nicked device and it's on the IMEI blacklist.
the other possibility is that the contract didn't get paid off so the provider blocked it because of that.
I'm generally always right on this - go get a CheckMEND report from here: http://www.checkmend.com/uk/public/check_start
Your IMEI goes in the Identifier box.
I appear to be having the same problem, I checked via that site and it didnt flag anything up, it was all clean. The problem started yesterday afternoon.
I've tried an O2 sim card in there which works, and someones elses Orange sim card in there, which doesnt
Orange have confirmed the phone is blacklisted, even though the site said it wasn't.

the problem is if this "legitimate" ebay seller, sold it to you before the contract was paid to orange, legally the phone belongs to orange, therefore you've bought stolen goods. Hope you used Paypal, they might offer some protection.

[Q] Wildfire: No Service

I was wondering if anyone can help me.
I recently flashed my phone which I have done many times. I then installed beautiful widgets from a apk off the net. Once I had decided I likes the software I deinstalled it and ever since I have been unable to get network service on my wildfire.
Whenever I try and connect to a network I get:
'Unable to connect to this network at this time please try later'
I am currently on baseband version 13.53.55.24H_3.35.149.25 but I have also flashed later radios and still have the problem.
I have also checked the phone information settings and radio is turned on so unsure where to go from here.
The phone is also unlocked to any network but I have tried a Orange, Virgin and Vodaphone chip and none work.
Cheers for any help ;-)
i was in touch with beautiful widgets developer a few weeks ago, and he mentioned there were 13 different pirated versions that they were aware of, and they were having troubles with them. the first thing he wanted was my google checkout receipt number, i wonder if you have picked up a virus somehow, with a malicious copy.
have you tried restoring a nandroid backup?
Hi
Yes I ran a nandroid restore and I still have the problem. I have also been into the phone's testing menu, phone information and it wont let me select radio band just comes back Set{Automatic] Unsuccessful ;-(
Tried numerous Roms and still the issue.
Will I have to totally flatten phone to get this working?
cheers
Have you checked your apn settings?
I have checked the APN section and I have one for orange internet and one for Orange MMS. I have looked through these settings and everything is blank except when I get to the MCC section.
One thing I have noticed is when In restore or use a new ROM I still have my details for Wireless setup etc so is it really doing a full wipe of settings?
Cheers guys
I have just spoken to Orange and they have informed me that the phone has been blacklisted hence no service. I have had this phone for over 6 months and now they decide to blacklist it even though I paid good money for it and it wasnt stolen...Nice!!!!!
Thanks for your help anyway guys much appreciated
why has it been blacklisted, and how?
The phone has been blacklisted by Virgin as stolen just recently even though I bought the phone over 5 months ago with original Virgin Chip, booklets etc. I have spoke to Orange (my own network) as the original owner is obviously trying to maker a claim which is indeed false.
I am in process of writing a letter to virgin explaining my predicament but I dont expect anything positive of the outcome. Last time I buy anything of a Forum all my own mistake to be fair!!!
Bought a Samsung I5800 just get me back up and running as the wildfire is now just sat at home awaiting to hear what Virgin say as I may sell it as parts.
cheers guys ;-)

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy
You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.
Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.
Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.
If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/
The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same
If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.
It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.
I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!
I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.
