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] Suddenly phone has lost complete mobile network

Hello there,
Guys really need your help. This is for my friend's phone;
Since last evening, his One has lost complete mobile connectivity. He says he didn't do anything out of the ordinary, nor did he drop the phone or anything.
Absolutely no network even after countless reboots. Once or twice the phone caught some network but only for a few minutes. Tried different SIM cards too. He had been using this phone flawlessly for 3 months, until yesterday.
He is an amateur at playing around with the phone, so I rooted the phone and installed a Lollipop based custom ROM hoping that would solve the issue, but no luck. Even reverted completely back to CM11 (44S) and then did a factory reset, still no coverage.
The phone is connecting to WiFi and seems to have no other issue at all. Only connecting to mobile network is the problem.
What do you guys think? What should I try to do now? Has anyone else encountered this issue, how did you fix it? I read a lot of posts here and on OnePlus Forums but haven't found an answer to this specific problem yet.
Edit-
I did try setting the correct APN, no luck

I have the same problem! I have tried everything: other modems, full wipes, back to 100% stock. The customer service keeps telling me to look at my APN settings...
Sometimes the phone is also stuck in airplane mode after rebooting.

Same here, I tried flashing a modem as well.
You can dial *#06# and see if your IMEI is visible, few users have suddenly lost it and hence no signal. For me the IMEI is present, still no signal

I had a similar issue yesterday after flashing CM12.1. Mobile data would completely cut out with no signal. I found if it toggled mobile data off and back on in settings it fixed it for the time being.

remove sim

Power off the phone, take your sim out and restart the phone without it, then power off the phone, insert the sim, and restart it with the sim in.
Or see if you can't borrow a friend's sim from another carrier.
Worth a shot.

I tried this multiple times, just tried it again but no luck. All other SIM cards don't work, even from different carriers (tried 3).
Also my APN settings sometimes show and sometimes they don't. When I try to save new ones, they don't show up.
My IMEI and baseband are visible and have not changed.

It might be worth it to wipe all the partitions individually from recovery, however first browse the forums to make sure you can do some sort of unbrick or restore the phone if it blows.
There may be data that is not being erased with lesser formats or factory reset. There were things stuck with my phone and it didn't resolve until I formatted all the partitions--except system, I think--after which it worked properly.
Do not just leap blindly in though, so you can be sure to get back out if stuck.
See #9 and #10 here:
http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
Good luck.

You guys would be glad to know that the phone sprang back to life on it's own
Hadn't used it for about 2 days and was ready to take it to the service centre, thought I'd give it one last try, inserted SIM and voila. Full network and working smoothly since.

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,
donk165

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.

Sim card slot 1 not working out of the box.

I have just got my Zenfone 6. Initially I did not insert any sim cards as they were in the other phone. I then start setting up the phone...updating the firmware and the usual stuff. It was only after it was setup that I transfer the sim cards over. Only then I found out that it is unable to detect the sim card 1. I am not sure if it is a software bug or something.
There is nothing wrong with the sim because I have 2 and I can swap them around. The sim card at slot 2 will always be detected. I have tried everything. I am running the latest firmware, I have factory reset my phone. I even tried to add some tape to the back of the sim card to make it thicker. None of it work.
Only thing I have not tried is to downgrade the firmware. I tried downloading the older firmware, putting it in the SD card to try and flash it from recovery, however it detects that it is an older firmware and does not allow a downgrade.

If you don't have your first SIM disabled in the Settings, then it is a probably HW problem (bended contact or manufacturing fault). Unfortunately, you should exchange your phone for a new one or service it.

It happened once for me, but removing and reinserting sim tray fixed it for me. Not sure it is some flaky hardware at sim1 or software issue.

I hope it's software, waiting for the next update. Going to do a factory reset and flash the full FW, not the incremental OTA.

Even i was facing the similar problem when I got my new Asus. Played around with various settings. Then i thought let's just do a hard reset. And that worked for me.

You too? I did try factory reset. Is that the hard reset you are referring to?

Yes.. Hard reset.. Wipes everything.. That helped me

When you first got the phone, did you set it up without inserting any sim? It's only after you finish setting up then you move the sim cards over?

Yep, when I get a new phone, the first thing I always do is factory reset to make sure everything is as it should be.
It doesn't hurt and it could prevent possible problems.

Question eSIM Broken, Sim Manager Screen Frozen, Unable to remove eSIM

Hi all, currently having an issue with my phone which I am unable to resolve. I'm beginning to think I may have completely broken my phone.
Yesterday I decided to install a Lycamobile eSIM on my phone. In doing so, it has broken SIM manager and also caused my device to stop recognising my physical SIM (which is with EE).
I've attached a photo of the issue. Here's what happens.
When I enter SIM Manager, the loading animation continues for quite a while. As you can see, the eSIM has no phone number assigned to it, and my physical SIM, which is inserted in SIM slot 1, is not recognised.
Whenever the loading animation decides to stop, er, loading, I access the eSIM. When I click to remove the eSIM nothing happens.
If I scroll down and go into More SIM settings and click to Remove all eSIMs, nothing happens.
I was on the phone to EE today for about an hour and a half. In that time, they tried to get me to install an eSIM but it didn't work. Every time I try to install it, the screen simply vanishes, taking me back to SIM manager.
After exhausting my options with EE, they referred me to Samsung. Samsung told me to contact Lycamobile, who in turn have decided to send me a new QR code in order to install a new eSIM...which also did not work.
I have reset network settings. I have cleared the cache partition. I have factory reset the phone twice. I read that apparently you should get the option to remove an eSIM when you factory reset, but I'm not sure if that applies to Samsung phones and that option has never been available to me. I did contemplate flashing the firmware (it has been many a year since I did that), but it appears that this wouldn't resolve the issue.
I'm stumped. The phone is in warranty, so I suppose I could send it back to Samsung, but unsure if and how they would be able to sort it.
Any advice would be hugely appreciated.

Try this: put a sim card in the 2nd slot and then try removing the eSIM.

Unfortunately the physical SIM is still not recognised in slot two, and I am still unable to remove the eSIM. As I said, whenever I access the eSIM and press Remove it doesn't work.

Have the same problem. Trying to fix it for a second day now.
What I tried so far:
Factory reset
Clear cache
Tried to remove it - nothing
Reset network settings
Reinserting sims in different variations
Checked physical sim in different phone - which works
Tried to reflash it with Odin, esim still there
Has anyone got some different ideas of what to do?
Thanks

If a factory reset doesn't fix a problem, then it means a bug in the software. This is unacceptable bug. You should try getting a replacement under warranty.

I'm assuming phone is unlocked. Any particular reason you are using EE firmware? I would try, via Odin, unbranded firmware

Samsung punted me back to EE and sent me a repair centre. They managed to fix it. According to the repair notes they replaced some hardware:
"Replaced a part that holds internal parts in place."
"Replaced an internal flex component."
"Replaced the main board (?!) inside your device."
They also flashed some firmware, which they say on the repair note was "the latest version" but I got a security update download notification as soon as the phone was setup.
This was done at a same day repair centre and I got the phone back after a couple of hours, which was unexpected.

To answer this question: EE are my network provider, and thus is a contract phone. The phone is unlocked though, EE did confirm that to me. I would have flashed firmware as a last resort but was keen to explore every other solution first. In the end, EE did manage to fix it by replacing some internal components (detailed in the post above).

Great! All well then

Sorry to bring up an older topic but is there any other suggestions to get this solved. I've got the exact same issue caused by a Lycamobile SIM. I've sent my phone back to Samsung but they won't repair under warranty because of minor cosmetic damage and I don't want to pay for an expensive repair for something that seems like it's a software issue.
