My issue started randomly and not after a drop or something like that,basically it wont work on 4G,3G,LTE networks,if you try to call me while the phone is set to those,it will say my phone is offline,i cant call anyone,and i cant connect to any mobile networks,tested the SIM with other phones and it works perfectly,factory reseted the phone,changed the APN and crap to the correct settings at my local service provider and none of those worked,so all im left with is maybe an antenna problem? a major issue is that the screen is c r a c k ed,like a bullet hit it,and i dont know if its safe to open the phone,the service dude i sent it to said,that to reach and replace them antenna he would risk braking the OLED panel and trashing this beauty of a phone,i also contacted mister samsung about this but since me self dropped my balisong on it by mistake,the crack makes the phone a guarantee voided piece of brick.Danke to whoever comes up with a solution to this mess i helped to make unsolvable.

Okay..
So i'm walking and stumble across a G4 Wizard on the road. Now where i'm from, South Africa, there is an option to call the operator and black list the phone.
I have CID Unlocked the phone with lokiwiz 3a and installed a new ROM (BlackDiamond 2.0) to try jack it up.
But when I inserted the SIM Card, the phone wouldn't receive any reception what so ever from the operator.
Does anyone have a clue on how they can get the phone to find signal.
I'll sell it and give u 50% of sale
is it overclocked >276 mhz?
Nope it isn't. Has that got anything to do with the phone been black listed?
What I think happens is that the networks block that specific IMEI number and make the phone void. Is there a way to change the IMEI number of the phone. Like i said, i THINK that is what has happened so I could be wrong...
Did I get it right you found the Wizard on the street and you SIM unlocked it?
If I lost my Wizard I would appreciate very much to get in back - even just to get back the data and contacts etc ...
I would have done that if there was any DATA on the phone. The phone was brand new and had no contacts/calendar notes - zip! And plus I had waited 2 days for the person to call me and no one called.
Now back to the issue......
If the phone was blacklisted then company's can do 1 of 2 things, not send a signal to the phone at all or just not allow you to make calls on the phone at all but the phone would still show a signal. The other possibility is that since you found it on the road maybe the phone had fallen and hit the ground hard enough to detach the antenna. There are ways around a blacklisting, but since that info can be used in the wrong way I don't give that info out. That info however is here on xda if you look in the right places though.
Phone is in perfect condition. Don't reckon its the antenna that has detached at all.
I've searched everywhere on xda and still have not come right. Info can be used in the wrong way? Doesn't make sense. Please PM me and try help me get it working, otherwise I just might as well just throw the G4 in the bin since it's of no good use.
Is it possible for the network to identify a specific IMEI number? If that is possible, maybe they have just black listed that specific IMEI number. Is it possible to change that figure?
My girlfriend has had a Samsung S3 (I9300) for a couple of months and has had no issues with it however she dropped it and broke the LCD . I ordered a replacement screen (Front glass, LCD, and digitizer) from eBay and fitted this without any problems. I tested all functions on the phone and it seemed to be working okay. The same evening my girlfriend went and run the update and went from 4.0.4 (I think) to 4.1.2 since then she has complained about signal issues which I have now witnessed myself. I wished she had waited a bit longer to make sure the phone was working fine before doing any updates as now I am not sure if this is a software related problem or hardware. There is no way to revert back to the older version to confirm software. I know one option on the software side would be to root it and install a customer rom but I have never done this before and even though reading through the forums the process seems to be easy I am a bit reluctant to do this just now.
The signal indicator sometimes shows a circle with a line through it, sometimes it shows a grey triangle with no bars in it and other times it will show a bar or two and even a full signal. I have noticed even without a sim in it that it can show a couple of bars of signal. I have not got this confused with the Wi-Fi signal. When trying to send text messages or make a phone call the following errors come up “Not registered on network” and “No signal found for mobile network”
Below is what I have done/checked so far
I have restored the phone to factory settings but as explained before this will only restore to 4.1.2. This time the only apps on the phone are stock apps, no additional apps have been installed just encase a third party software may have caused issues.
Her sim will work in any other phone. I have an S2 and have ported my number over from a normal sim to a brand new micro sim to try in her phone. Both of these phones are on O2.
I have made sure the IMEI number is correct and matches what the phone came shipped with.
I have double checked the APN details and these match what my S2 has. Although I am pretty sure this is only for internet and MMS and would not affect SMS and phone calls.
After check over the settings and restoring to factory settings I have fitted a replacement antenna which I also got from eBay. I doubt I have damaged the mainboard as all other functions on the phone work fine. (Touchscreen, Cameras, Sound, Wi-Fi)
For some reason I can get the phone to work at my house on both GSM (2G) and WXCDA (3G) although it seems to be more stable when it is on GSM. As soon as I leave my house and go into town (approx. 2 mile away) or over to my girlfriends (approx. 20 miles away) it will stop working. I have gone onto the O2 website and entered both of our post codes on the O2 network coverage checker and this reports that there are no services down in our area and that we should have a good signal.
I have come on this forum for some advice and hopefully someone can recommend what I could do next. I have had a little browse on the forum already but is there something I have missed? Should I root the phone and install a customer rom? If it was caused by the official update is there an a hotfix of some sort coming soon? Or is this a genuine fault with the phone? If it is a fault with the phone and it has not be caused by me I could try sending it back to O2 (where the phone was purchased from) or Samsung seeing as I can’t see any warranty seals so think I would get away with this.
Thanks in advance for any responses I get to this and I am sorry if I have rambled on and provided info that is not essential.
Flash O2 stock rom via Odin .
If that does not fix it its a hardware repair job and you will be refused warranty as you have self repaired .

If it locked once you start with non-original operator sim card it will ask you for unlock code, so you will know it's locked
do you receive sim error after airplane mode ?
Mine has a bended / broken sim reader pin and didn't recognize any sim card and after restart I got SIM error msg.
I have somewhat of a like issue. After restart takes a LONG time to connect and update the tile. Wife's phone, will state no service or emergency calls only, but she can text out AND I can always call her, so POSSIBLE the tile is not updating. Sim card replaced twice by ATT. ATT stated working on local towers for LTE upgrade, and after a whole weekend of no text coming in (able to text out)(???) all incoming test text messages (say 25) arrived at 6am on Sunday morning.
no data updating (email) while in this half-working mode. next thing I can think of is get new phone.

If the phone is the ATT model and is still locked to ATT then you obviously have an issue with the phone and should sen it in for service. There is no reason why an ATT phone and ATT SIM should have an issue on the ATT network otherwise.
I have this issue as well but only since I got it back from Nokia repairing the dust in the front camera problem. They changed the internals for some reason and now I have No Service and also now have new IME number. I contacted them and they said try a hard reset which didn't work then said I would have to send it back again for this to be repaired which when I got it back today has the same problem still. There is nothing wrong with my SIM card and have even received a new Orange one which still did the same. When I contacted Nokia they were next to useless saying I need to send it away a 3rd time (my phone was perfect before I sent it away apart from the dust in the front camera...don't I regret getting this fixed now!) which I declined and have asked to speak to the manager. I have to wait 3-4 business days for them to ring me and see what can be done. I know this is probably not much help but will let you know the outcome as it might be a setting or something I can do with the phone.
One thing I have found is Nokia Care is they are the most unhelpful company ever! Basically just suggesting I keep booking it online to be collected for repair. Once this is sorted I hope I never have to deal with them again!
At&T no Signal as well
Default AT&T Lumia 920 bought from ebay NO SIGNAL ! I flashed it but... no signal
--------------------------------------------------------------------------------
I bought this yellow Lumia 920 form USA. I live in Europe.
Unfortunately it was locked, I called AT&T and they gave me an unlock code and now it's unlocked.
I put 2 different SIMS inside but the phone shows no signal at all. It reads the SIM from inside ( services etc) but It will not lock to a signal.
When I boot it it shows an airplane mode and in 2 seconds the no signal icon. The airplane mode is disabled thought I checked enabling and disabling.
I decided to flash it to Rogers after reading all these comments here using Nokia Care Suite. It was succesful. The conversion was from RM-820 AT&T to ----> RM820 Rogers Canada.
I had the ability now to change from LTE to 3G and 2G but to no avail. The signal remained dead and it wouldn't find any signal after searching for new networks associated with my 2 sim cards that I tried.
If I flash it again to the rm-821 euro dev rom will it work ? The thing is that I can't find it nowhere to download it. Where did you guys found it from ?
Thanks
Lumia no signal
Try hard reset!!!
Permanent no signal sounds like it could be blacklisted by the networks, check the IMEI here and it should show if it's blacklisted http://www.amta.org.au/pages/amta/Check.the.Status.of.your.Handset

Have you had any luck for fixing this? I also have the same issue. I gave my lumia 920 for screen replacement at Nokia care and after some time, it would just not pick any network. Please help me
***I have the fix***

I had this issue with a replacement Lumia 920 that I ordered online. To fix this you will first need a t5 torx screwdriver in order to remove the two screws from the bottom of the device. Once those are out you have to pry the main body of the phone from the polycarbonate case and expose the bare backside (*giggle*). look to the upper right portion of the device for a really thin coaxial-esque cable... this is the antenna. To fix my issue I simply had to push the connector piece back into it's slot. There will be a firm but tiny click once this is properly inserted and you should now receive a signal on your 920 again. (apparently the build of the phone makes this piece pretty easy to become disconnected which is why we see a lot of this issue from various 920 owners). I hope this helps, if you need further instruction/pictures let me know.

Hi there if you can also send me some pics etc on how to do this. that would be great.
I got this wife for my wife and have it for close to 5 months and it won't work.
And she really loves the phone
thanks

I have this same issue, although hitting the phone on my hand or flexing the phone will cause the service to come back until its jostled again. ive tried to find a connection with the antenna but no luck,
I have the same issue too...
At first I notice that my phone became hotter in my pocket and the battery drains quicker than usual.
After that I just thought maybe it was because of the bad signal on that area.
Then I got home and facing the same thing, my 920 still got "no service".
But I notice in the full signal area, my phone still can catch the signal. And when I get into the lesser signal area, all I got is "No service"
I've handed it up to the Nokia Care. And they fix it and cost me Rp.750.000 (US$60-65).
And still I'm having the same problem :crying:
Same problem, no connection on 3g, but 2g works fine
Hi,
I am having a similar issue with my unlocked lumia 920. While using it with 2G I have no problems, I can make phone calls and the internet although slow, works. Whenever I decide to switch to 3G it can no longer connect to the internet nor can I make/receive phone calls.
The antena cable is new and the signal for 3G shows 2-5 bars (but sometimes it looses the signal. Any hints??

tnx very much for advice, i bought used lumia 920 yesterday and signal was very poor and often without reception then tried this and VOILA, there is now full 3G (H) signal in my room. When you push connector here is a smaaaaaaall *click* and thats almost sure sign it's reason for bad signal.
Hi guys,
First post so please bear with me...
The phone was dropped recently and screen smashed up badly.
Replaced screen and thought all was working fine until tried to make a call/send a message when I discovered that the phone had no network access...
Here's the diagnostic process I've been through...
Wifi works100%
Sim works in other phones
Other sims don't work in this phone.
Checked the antenna assembly to ensure contacts okay
Sim definitely reading - able to read sim contacts
Switched to airplane mode, reboot, turn back on - no luck
Searched for networks manually - no networks found at all. Another phone (samsung galaxy gio) finds all three (Optus, telstra, Vodafone)
No networks detected automatically either
No network detected using 2g only
So, if my wifi is working fine, that should rule out an antenna issue which to me indicates a hardware fault with the network side of things...
Is there a way to verify this is actually the case? And if so, is there a way to repair/solve it without doing a motherboard replacement???
Here was I thinking that it would be a cheap, easy repair... :/

If you want it free of cost so first try flashing new firmware via odin and then check it if not then give it to service centre !:good:
Make sure you're using a stock rom just in case it is a software problem, but it looks like a hardware problem to me. I recommend taking it back to the repair centre where you got your screen replaced.
I don't think it is possible without a motherboard replacement.

thanks
I think I'll do a total strip down again just to make doubly sure that i've got absolutely everything connected in the right place and then if it's still not resolved, I'll look at sourcing a motherboard through some chinese friends...
The phone was actually purchased when in china, and as a result I had to flash it with an Aussie rom to get the google back in android. It's all worked fine since then until dropped which makes me think it's hardware related. problem with buying it in China is that I can't seem to find a motherboard online for it galaxy ace 5830i (the 'i' is the problem... can find plenty of 5830 mobos but seems the consensus is using a 5830 mobo will brick the phone...)
Oh well, thanks for the advice guys.
Even i had the same problem, but i solved it by flashing a stock ROM. You can try that or flash a stok kernel
recently I also had this same problem, even installing the stock rom did not solve, so I researched in several places and saw what could be problem with the IMEI, I did the whole process of repair IMEI and my phone is back to normal , try this method:
http://forum.xda-developers.com/showthread.php?t=1968360
Sent from my GT-S5830i
So...
I pulled it apart again to double check everything and noticed that the cell chip had come disconnected from the mobo upon impact and was only attached by three copper strips. After staring at it under a bright light for a while (no magnifying glass was to be found!), we stuck some super glue under it and tried to dry contact all the points... but it still didn't work.
However... after talking with a mate who's into circuit boards, he suggested that I try putting the mobo in the oven at 350 deg for 15 min to resolder all the joints as they use low-temp solder on these sort of boards.
I've got nothing to lose, so will be giving this a try when I get a chance and see if this brings it back!
I'll post back my results.
Yeah, and I recommend using a fine tip on your soldering iron just to be safe.

So i've had my S6 edge since 2017,after 6 months something happened out of the blue (i've dropped the phone but there was no damage the day or even week it happened) and the 3G/4G wouldnt work,it acts as if there is no SIM card in it when its on these spesific settings (AUTO 4G/3G/2G, 4G/3G, 3G) anything that dares to have 4G or 3G on it,the phone will act like theres no SIM in it,the mobile data wont work,and when someone calls me,it will say i have my phone turned off.First thing i did is go to the SIM carrier,they reset the phone,reset the APN settings,gave me a new SIM just in case and sent me on my merry way.Rubbish didnt work,so i am here to ask,could this be a hardware failure or should i do something with the software side.I should mention that the screen is cracked,would this be a dangerous repair because of it?
