Hi all - hoping I can get some help here with the following as I have no idea what to do after failing to find any solutions this far.
I got an ROG Phone 5 (base model) a while back from a well known online marketplace reseller (never again!) and only recently tried using it, but for some reason the phone does not recognise or connect to any network at all. I have attached a few screenshots of what I mean. I get the same thing regardless of whatever SIM I try.
The only possible thing I can think of now (and am dreading) is that it may be a blacklisted phone but no idea how to confirm this.
Any thoughts?
Thanks in advance!
Does the device have an IMEI? Check that (but don't post your IMEI here).
Yes it does have an IMEI number (two in fact)
this happened to me too. did you find the solution?
This may be because of a recent update.
Remove the sim card, and reset it to factory settings.
There was a recent update that has caused problems.
I have the 5s, and the Wi-Fi connection has not been working since the last update, a few weeks ago. Also, now there is problems with the cellular data connection.

Ok this is a weird one.
Phone was working ok yesterday throughout the day. In the evening I noticed I had no signal so I rebooted the phone but still nothing.
Checked my operators (O2) website and it said there was a fault with my local mast. Ok I thought...should be ok tomorrow.
Woke up in the morning, still no signal. Mast still showing a fault. So I travelled to work 6 miles away, but still nothing. My local mast in now working again, as is the one near my work, but still can't get any service.
Factory reset to no avail. Tried another sim card of a friends in my phone but still nothing. If I try to search operators it brings back the usual UK list, but if I try to register on the network I get 'Currently unavailable. Please try again later' (or words to that affect).
Im starting to think it's the radio in my phone. It's just strange that it coincided with the fault on my local mast.
I also have the issue that I slightly cracked my screen about 2 month ago, so now I apparently have voided the warranty on the phone despite it being less than 6 months old.
Anyone have any suggestions? Or is my phone screwed?
N.B. I should probably add that I am on OTA Android 5.0, have been for a few weeks now....and my sim card works ok in another phone.

Have you tried reflashing a radio .img using fastboot while in the bootloader? Or maybe the cell tower is still having issues.

The warranty doesn't cover non-manufacturing defects. I don't think they'll replace it under warranty if its physical damage/wear and tear that didn't occur during the manufacturing process.
Also, Google's "policy" of a one-time replacement of a cracked screen for US customers is NOT part of any sort of warranty, more of a "why not since we have so many spares from people RMAing because of silly things like speaker hole size, light bleed and loose power buttons". Google has the right to refuse if they don't feel like it regarding this "policy".
Do I have to have rooted to reflash the radio ?
The mast isn't having issues anymore according to my operator, but I'm in a different location now anyway so am on a different mast.
Unfortunately I'm in the UK so don't qualify for the cracked screen replacement as I looked at that option when I first did it.
Does the fact that I can see the list of mobile networks in settings mean I don't have a hardware fault with the radio / modem?
1 more thing I have just noticed. I was going to check my IMEI to see if it was somehow blocked. However, when I go into Settings > About Phone > Status, the IMEI shows as 0.
When I dial *#06# the IMEI also shows as 0.
I'm guessing that's not right and it's the reason I can't connect to any network ?

That's probably your issue.
Flash a radio and cache.img from factory images.
If that doesn't work and you don't have an EFS backup then there's not much you can do.

Thanks. Not sure how my phone can just lose it's IMEI. Especially as I haven't rooted / unlocked bootloader, etc.

It's happened a couple times to people, mostly with cache derps. Either that, or they restored an EFS backup from a device with a different IMEI (which damages it permanently unless you had an EFS backup of the intended IMEI), flashed something not meant for their device, or something else that damages it.
I have a similar problem. No service, sort of stuck in airplane mode. Radio is off and I can't turn it on. It all started after I upgraded to 5.1.
I've tried downgrading to 4.4.4, cm11, flashed different radios etc... I do see IMEI though but my radio is unresponsive. When I manually try to save APN settings nothing happens, they don't get saved.

I had the same issue as the OP - a tower was down in my area, and even after it was restored my phone got stuck with no mobile date service (although the odd thing is, voice and texts worked fine, just not mobile internet).
A factory reset was the only thing that fixed it.
I have a note 3 sm-n900t that I just bought from a private party. He said it's unlocked so I bought it and haven't had any issues until I upgraded to lollipop. One I upgraded via Odin I was having issues so I found out a factory reset would fix most issues. So after a factory reset it seemed better but had no network and the phone kept telling me I needed to insert a t-mobile sim. Couldn't find anything on request unlocking so I downgraded back to 4.4.2 and magically my network was back. Not sure what this issue is but I've checked apns and network settings and finding nothing works. Any help would be appreciated, Thanks.
Edit: I figured It out, it just took an unusual amount of time to connect to my network.
Hii... Have been searching forum but seems like no one has the answear
Galaxy s7 european version. Phone worked perfectly for 4 month and then suddenly I lost mobile network and service Tried hard reset, network setting reset ect. nothing helps Put simcard in different phone - everything is ok. I red that this problem most likely can t be fixed by software... Is that true? Can I try something else to fix this? Whats the cause?
Thanks for your time
Still got an IMEI number when you call *#06# ?
Yes IMEI and SN pops up. What does it mean?

I guess tomorrow I will return the device. Bought it from official carrier. Doubt it s blocked. Strange that no one has solution to this problem yet because there are quite a few similar posts online. :/

Hey there. I have the same issue with Vodafone Sim card AUSTRALIA. phone just stopped working all of a sudden. Why would they blacklist it? Other sim cards work on the phone.

have you been able to resolve your issue? what was the fix?
Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.
I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.
A few weeks ago I started having signal losses on my D820, later on it stopped detecting my SIM card altogether after I reset it.
It's been going on-and-off until about 2 weeks ago when a factory reset and cache wipe seemed to have fixed the problem - or so I thought - until it happened again today in what seems to be a permanent metamorphosis of my phone into an over-glorified 5" tablet with NFC.
So I started snooping around the googles, seems to be a common problem.
(can't post links yet but google isn't lacking results under "nexus 5 no sim no signal" and "Nexus 5 SIM not recognizing")
So far none of the "Turn airplane mode on and off" or "Reinsert the SIM / clean the slot" tech support quotes helped. The phone is physically intact, and none of the 3 SIMs I have in my disposal get any signal on the device in the rare case they even get recognized (My brother's G4 works fine with all 3). I did a few full factory flashes - ROM, Radio, recovery, everything (M4B30Z - latest 6.0.1, MMB29S, and even went back to 5.1.1 LMY48M). Also tried the latest CM13 snapshot, later on with a factory radio image on top but absolutely nothing. The CM ROM managed to consistently read the SIM but it didn't get any signal.
I would highly appreciate any information or insights, and even though I'm not exactly an expert I will be more than happy to help troubleshooting this jazz.
The phone shows the correct IMEI#? Phone is not blacklisted for some reason?

No reason to believe it is. Had it for over a year now, came unlocked without any contract with in closed packaging from a trusted retailer, IEMI was fine on the day of purchase.
It shows the correct imei via dialler?
Did you check imei on blacklist checker on swappa? Not likely to be blacklisted but you may as well rule it out.
If it's not blacklisted and can't be resolved via flashing roms, it could be a hardware failure.
The IEMI is fine and the phone is clean.
It could be hardware but that doesn't explain the problem being temporarily solved for quite a while by wiping the system, and a lot of the users complaining stated they started having the problem after upgrading to 6.0.1.
I've been running on stock unrooted MM for a while with no problems. A couple of people at work also run stock MM without an issue. I wonder if the problem is related to a particular batch.
So a few weeks ago I bought a pixel for my son from someone local. It was very cheap and my son was using it for school using his mobile data. Today I have then tried to use the phone as I await for delivery of another handset and am faced with some issues. First the phone won’t connect to the WiFi. It’s currently running Android 8.1.0 May security patch and no matter what WiFi wont connect. At times it will say saved network but won’t connect. I have tried to reset the phone but alas no luck. The other issue is that phone is sim unlocked and can use my ee and 3uk SIM cards but the oem option states “connect to the internet or contact your carrier”. Unfortunately I cannot get the person who sold me the phone and all I remember is he told me he bought it from Very UK. Any suggestions please to fix this?. I as under the impression only phones which are sim locked have locked bootloader and also any ideas on how to fix my WiFi thanks.

Seems like you've bought a Verizon locked phone. Those phones has locked bootloaders and recently there was a tutorial on how to unlock those bootloaders. So it can't be done on the traditional way. Here's the tutorial: https://www.google.se/amp/s/forum.x...unlock-bootloader-verizon-pixel-t3796030/amp/
You say you're running may security patch see if there's an update first to June. The non Verizon phones got that already on Monday.
Another thing you could try is to do a factory reset and don't restore any backups at all. Because some backups tries to restore previously remembered wifi. So try that and connect to the wifi. If all this doesn't work then you could try to enroll into Android P beta and see if that fixes it. If that doesn't work then it's an hardware defect. If you cannot get a hold of the person who sold you it then I'm sorry to say that's probably why he sold it to you cheap as he probably knew about the problems it was having. I personally would try to get a hold of him first.

hmm many thanks. How do i tell its a verizon device as its currently working with a 3 uk and ee sim card. Am just installing the android P better now and does this resolve the wifi issue because without wifi I wont even be able to follow the bootloader unlock guide above.

Bootloader unlock has nothing to do with carrier. If you could use 3 UK Sim then you're fine. Unlocking bootloader is only needed to flash custom ROM with some exceptions. Are you able to turn on WiFi and see your wifi but not able to connect or does it not turn on at all?

Hi thanks WiFi can be turned on but it won’t connect. At times it says connected and just saves the network. Mobile data is working fine so completely lost, and now trying to flash the P beta.
Just tried android p and same issue. WiFi will try and connect and just end up with saved but it won’t actually connect. Any other ideas please?

Have you tried pressing the wifi name and then press forget and try to put in the wifi password again. Is it the same issue on all wifi? Like at home, school, friends home or only at home? If it happens everywhere then I don't have any more ideas. My thought would be that it's a hardware defect. Is there no chance of getting hold of the previous owner?

They would probably only need the IMEI number, but if it's out of warranty they'll refer you to a repair center. Wish you all the best and hope that they'll be able to fix it. Let us know what Google says if you do contact them. Keep us updated please.

Thanks will update you as soon as I have spoken to them. The person I bought it from did say it was only bought last year from Very UK and it also looks mint. Has anyone had any dealings with Google RMA with phones without receipt?
