Nexus 5 - No service....help please

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 ?

Only an unlocked bootloader.

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.

[Q] Google Nexus 5 - No Mobile Network Issue

Hello,
I am from India. I had purchased a Google Nexus 5 phone (Black/ 32GB) last year (December 20th, 2013)
I have started facing a serious issue since yesterday. My entire mobile network went down all of a sudden. Tried using other SIM but of no use. The same SIM works fine in other phone. Other functions including WiFi in Phone works perfectly fine.
A couple of things that I noticed are:
1) When I try to search for the Network manually, I get the message "Error while searching for Network".
2) I noticed that the PREFERRED NETWORK TYPE is defaulted to LTE. I cannot select any other option 2G or 3G.
3) When used Choose Automatically option - it starts with Automatic Registration and then flashes an error "Can't connect to this network right now try again later"
I tried doing a Factory reset hoping that it would work. But, no success. Have contacted LG Direct Service Center (since I bought it from retailer and not from GooglePlay store) and they suggested it's a PCB problem and it needs to replaced which would cost me around 12K INR. Which I am not ready for.
Please let me know what needs to be done. Any help is highly appreciated.
Regards,
Vijay

He's clearly not in airplane mode.

I have tried with all basic troubleshooting options, kindly check the attached screenshots. Please please help needed urgently.

I was going to make a new thread, but his problem matches mine almost exactly.
Hi guys, i have this problem for over a week now.. A very frustrating week i must say. I got this n5 about a month ago, my uncle got himself a G3 and gave his nexus to me.
Everything was smooth, amazed by the phone, everything working fine, happy as hell. It all crumbled when I went to spend the holidays at my brothers, where he lives my carrier doesn't work (everyone uses another one). When i got back to my house where the mobile network works fine it just stopped. All other sims would work on my phone and my sim work on other phones.
I gave it a time, thought it would be cause i spent too much time on my brothers and it would be ok after a while. It didn't. Then i started to worry and try to fix it somehow. First i got a new simcard (same carrier), no bueno. They told me to restore my phone and stuff, it didn't work. The phone has always that empty triangle, doesn't matter if it's 3G, 4G or 2G.
So I came to the internet look for help. I saw that some people had bring this to the LG, their response was to do a recovery with fastboot and then put 2G on the mobile network. For a moment i thought it was over, my phone finally had some bars !! But to my disgrace I can't make nor receive calls, i can only send/receive SMS and access internet thru 4G, not 2G as the support said. Oh, if i put 3G or 2G dem bars go missing and the empty triangle ****er appears again. Still, my simcard works on every other phone but now only one carrier works on my phone (not mine unfortunately).
Then I started looking on forums like this one and a whole bunch of others and tried many things, all of them unsuccessful.
I tried many things, maybe forgot some but will list those that i remember.
I tried to flash the factory rom. Then tried to flash only the radio of previous androids (tried too many of them to count). Dialed that *#*#4636*#*# or smth, put LTE/GSM, only LTE, activated/deactivated radio. Airplane mode on/off. Tried to recovery on fastboot again. Tried to make new APN. To finish my story, put a Cyanogemod rom and it also didn't work.
So now i decided to post here as my last shot before i go to that carrier that still works. Also, what guarantees that this carrier won't stop working like the others? I'm afraid that may happen. Further informations, i saw many people complaining about T-Mobile and other carries, but I'm brazilian, so it's not one of these. My carrier is Oi and the one that still works is TIM.
The two threads i got most tips were these and some sites in portuguese:

http://forum.xda-developers.com/google-nexus-5/help/bug-make-receive-calls-wifi-enabled-t2839814
Thank y'all in advance and sorry if my english make it hard or impossible to understand.
My fingers are crossed!

Mobile data stopped working, APN is correct.

So just randomly yesterday the mobile data on my Honor 6x just cut out. I am just getting the service signal bars, no 3G, 4G icon. I've tried resetting APN and formatting the phone back to original spec, but I still have the same problem. I also ejected the SIM and reset it just for a shot, but nothing.
I am using a T-Mobile MVNO called TAG Mobile if it makes a difference. I can make calls and text fine, and wifi works as well. Just the mobile data acts like I have it turned off. I've checked to make sure all toggles are switched on for 4G but to no avail.
Oh and I am running Nougat 7.0 emui 5. I've been using it for a couple months with no issues till now.

Can you try another SIM card?! Just to know if the issue is from the phone

I don't have one available right now, but I will try to get a replacement SIM sent out to me. I don't really have anybody near that would let me borrow their SIM either.

Ok, once you do it, let me know the results

Weird, the network came back up randomly. Didn't even need to try a different SIM card. Thanks

My friends One cant make calls anymore?

So me and my friend swapped our Ones because mine had a broken aux port and his was fine, but his casing is pretty battered. So my phone which is now his, its been fine for a few weeks but a few days ago, the network has been playing up. He cannot make calls, but can send texts. But, in network settings, no networks appear when you go to select one. The APN settings are correct, signal is a bit hit and miss, sometimes its there, and sometimes its there but cannot connect to the internet. WiFi works fine. I also tried swapping SIM cards and the same issues were happening with my SIM or his SIM.
It was running Sultan's CM13 ROM with the "firmware_fixed" firmware/radio. I thought maybe something had gone wrong so I then flashed Sultan's Lineage OS and it is still having the same problems. I've tried a full wipe and factory reset, no luck.
Does anyone have any suggestions on how to fix it? or could it be a hardware issue?
Thanks,

Try flashing other firmwares as well.

I've tried flashing the idprophecy's c1_11_00006 firmware , the stock 0241 modem and also the firmware_fixed one. All of them are doing the same thing, the main issue is that I get an error while searching for networks. I can call my network operator's topup number but people cannot call me, it either cannot connect or goes to voicemail.

My friend is on EE and I am on Three. Both are different networks, and with both sims, it does the same thing, It cannot find the network. I have tried both sims in the other OnePlus One and it detects the networks with no problem.
I guess the next step would be going back to full stock and see if that works. If that is a no go, I can only assume its a hardware issue

Hi again,
I have tried again to fix this phone but I think I have exhausted all software options. I fastboot flashed all the original stock files, completely went back to stock ROM and the same issues are there. It gets signal, and it says that mobile data is working, but doesn't actually connect if i open the play store etc. I managed to get a call to work for about 5 minutes before the call ended on this phone, but was still going on the other phone which called it. It does allow calls sometimes but they drop out, other times it wont dial at all.
At this point, I can only assume there is some antenna damage or something similar? I did a quick google and worked out that the antenna is on the daughter board on the bottom of the phone, and there is also an antenna wire also. Would it be worth it to buy these replacement parts and see if this would fix the issue?
Thanks

You only need the network antenna,I suppose,but is there any recent activity that could damage hardware in your device?

Its my friends phone now, we traded. And he said he hasn't dropped it or anything like that. But judging how battered the phone is that he traded me, he might have damaged it and not realized. It had been working fine for me in the 2+ years I had the phone. And after the trade, the phone worked fine for him for a few weeks. Its very weird. I've tried my SIM and his SIM in the phone, both sims work fine in my phone but not his.

I see,so if you believe that there could be a hardware damage,you can go with the network antenna and see if it fares.

Anyway to recover from this?

T-Mobile Variant OP7P, was on Latest Pixel Experience+, Sim Unlocked, Unlocked Bootloader - Went to transition the phone back to T-Mobile stock OOS, not sure what happened. But since, The Sim card is recognized, but carrier and phone # are not, resulting in no service, also cannot modify APN settings.
Have tried to MSM back to all different firmware, remains the same, SIM Active, but not usable for mobile data or anything else

Try clearing the sim toolkit data, clear system cache and network reset.
Replace sim card. They are suspectable to ESD; always handle them like a stick of ram. While they are dirt cheap, a failure can prove costly in other ways.
A factory reset to purge it if less drastic measures don't work.
Not sure, never had to play with that.

Hello, I was previously on a htc u11 and had something similar as in no data connection and no wifi, Mac address issue,,the thing that fixed my problem was an "erase persist" command in bootloader, not saying this will help your problem , just throwing it out there.

I MSM'd to stock firmware versions around 10 times, nothing different. Should've mentioned that the SIM works fine on my other phone, thing is totally clueless on how to read my SIM card it seems, registers as having one inserted and all, just doesn't do anything
Cannot even access APN settings when updated to the latest TMO Android 11, started from first Android 9 distro and continued updating on both paths, TMO and International versions of OOS, even tried flashing back to Pixel Experience- the ROM that was being used right before this took place.

Weird thing is Wifi works, think I may have messed up EFS but not sure, IMEI is still valid and Wifi works, seems like only 2.4Ghz though with the speed of it

Try a hard reboot.

Hard reboot stimulates pulling the battery. Not normally found in recovery. Done by holding down a button(s) depending on the phone or physically disconnecting the battery.
