[Q] no service - Nexus 4 Q&A, Help & Troubleshooting

I have just received a Nexus 4 off ebay today. Said it was a month old, unlocked etc.
I got it for the Mrs. She powered it up, and inserted her O2 sim and it said "no service".
We haven't done a thing to the phone but turn it on. Is there a reason for this?
I've attached the software details.

Have you tried to set the Settings->Wireless&Networks->Mobile Networks->Network operators on "Choose automatically"?
It may have been set to another carrier by the previous owner.

Clicking set automatically doesn't seem to do anything. And when she clicks mobile networks, which usually shows a list, nothing happens.

Have you tried adding your APN manually

http://www.geeksquad.co.uk/articles/chapter/595-04-how-to-set-apn-settings-for-the-02-mobile-network

Take the sim out and make sure its in properly, then re insert and reboot, and try again to find network, try choosing o2.
I had this problem and it just seemed to fix itself while doing the above

Wait is the IMEI present in settings?(don't post a photo)

It does come up with a IMEI when I go into settings. As you can see from the attached, there is no signal at all. I've tried mine and her sim. This phone looks brand new, the guy said he used it for a month, it's running 4.3. Everything works but this.

Did you update the APN or are you just going to keep telling us that the guy used it for a month and that it looks brand new?

Whats the point of even putting in an APN when I have NO signal and it can't even scan for networks.
Secondly, I think it's faulty. I noticed the sim tray isn't sitting flush, with or without a sim card inside. And more worryingly, I just tried the to add an APN, it didn't even save, and there is this rippling effect on the screen if I press the back of the phone, or front. It's in the exact same spot. Even holding the phone in the hand and gripping causes the effect, It's like an invisible stick is poking at the screen, distorting it. Hard to explain.
Maybe all this is irrelevant, but I'm suspicious.

Have you tried performing a hard reset? It could possibly be blacklisted, amongst other things.

Looks like the IMEI is blocked. This can mean the phone is reported stolen and therefore the IMEI is blocked.

one way, but i dont know if this will help you http://www.t-mobile.com/VERIFYIMEI.ASPX
heres another way https://prod.eie.net.au/portal/template/MYMIMEIInquiry.vm

Thanks for that. Both tests included a seperate paid one, show no problems, no blocked IMEI.
The only road I can think of to go down now is the whole unlocking bootloader, flashing other modems/roms etc.

is that micro sim working in another phone? if your sim card works in anotger phone, then the n4 itself is the issue. my first n4 i returned within a day, it wasnt reading any sim cards at all.

Both sims work fine in other phones. I'm so annoyed by this, it's near mint condition. This guy had to know it was faulty surly.

it could be the phone itself then. the n4 has a known issue with faulty sim readers. btw, was your sim cut down to a micro size or is it an actual micro sim?
btw, this simms works fine too

It's a proper micro sim. I just want to be sure that it's nothing my end before I start moaning and getting refunds. But at the moment I think there is no other option. Would trying to flash another radio make a difference? Or is it futile?

the radios might play a role for a little better or worse reception, but one wont not give you a connection and another will is highly improbable.

It's imei related. Since you stated it's present & not erased, that means it can't register with the network due to a possible blacklist.
Also micro Sims and normal Sims that are cut will both function in the nexus(I've tried both).

Can't get HTC HD2 working again!

Hi
Ok so my phone was working fine on a custom ROM when suddenly yesterday an exclamation appeared next to the phone signal and stopped from receiving/making calls and texts. I thought it had just crashed but after soft and hard resets and changing to a few others sims I just can't get my phone signal back.
Really strange as everything was working fine. I now have trouble flashing custom ROMs and am struggling to run a stock ROM because I'm on a mac.
It's driving me crazy as my phone is now useless.
Any ideas guys?
thanks
Quick update
I've managed to get the Leo Lite ROM running and everything is good except that damn exclamation mark next to the phone to phone, which means I can't get the phone working.
Anyone know know why this is???
Have you tried the sim in a different phone?
could just be a simple issue
And I know it a simple thing............but have you got flight mode on?

Thanks for the reply John.
Yeah currently having to use the sim in an ancient motorola and it works fine, tested with calls and texts. Also tried turning on and off flight mode but still that bloody exclamation mark stays.
That sounds like its been blocked. Theres a network there it just isn't letting it connect. Did you buy it second hand? or off ebay?

Hey Sam
Do you know what, I did buy it second hand, from a reputable store in town.
However this raises more questions than answers;
1. Why would it be blocked after several weeks of normal use.
2. Doesn't some sort of message need to be displayed stating the handset has been blocked.
Does anyone know if this is what happens when a HTC HD2 is blocked? i.e. the exclamation being shown all the time.
I presume a handset is blocked for security measures like theft. I will take it back to the shop tomorrow, they will have all the details of the person who sold it to them.
However is there no way this can happen from flashing custom ROMs? Even though that doesn't really make sense cause I had a ROM that was working fine and this happened when I was out and about.
It could be a bad rom, but it certainly wouldn't be in every rom.
I think id try going back to the stock rom, radio and spl (i.e an sd card flash, do you now if it has a provider locked rom?) and see if it is still there. If it still won't work, then it's definately either hardware or network.
The reason it could have taken weeks is, , seller trades in phone for cash, waits a little while, thinks 'i know'..., reports the phone lost/stolen to claim on insurance, insurance won't pay out without the imei being blocked.

Well I've tried flashing at least 6 custom ROMs, all show the exclamation mark.
The phone was sold to me as being unlocked to all networks, however I never tried with anything other than a o2 sim.
Now going back to the original ROM has its own problems. First off i'm quite new at this so sorry for sounding silly. How on earth do i go about finding out what the original stock rom, radio and spl is?
When I have these I can't easily go back as I don't have a pc, using a mac. I would have to use the sd card way but I can't find an official signed .nbh file.
I have a brand new T-Mo US HD2 with similar issue (out of the box). It's like the radio will not initialize. Did hard resets, tried to force it finding a carrier, etc, and it just will not turn on the radio.
I did find out that there is a likely issue with my SIM slot. If I attempt to remove my SIM card (which works fine in other phones) it is almost unremoveable and feels jammed in. However, once removed, I get connectivity via wifi and touch response is great.
If I insert a SIM card, it takes a LOT of pressure to reinsert it (yes, inserting it in the correct orientation), and the phone cannot connect turn on the phone's radio. Also, I get random phone.exe and credential.exe error message (plus the phone becomes very slow.
Don't know if you have any of these other symptoms, but the lack of connectivity sounds similar.
Supposed to get a replacement HD2 today, and we'll see.
I had the same problem too. I got unlocked code from tmoile and everything working fine for a month. It was working great after upgrade the latest rom 3.14 from tmobile download site (i got the message from them to upgrade), until i went out off country last month then the phone could not turn the phone's radio on. It kept at airplane mode. I been try to flash back and forth all the tmobile .50 stock rom and still having the problem.
Does any one know the issue to fix it? TIA
Looks like a hardware fault. You need to open case and check bottom two brass hinges are in working order and correctly hinged to make contact with antenna which is on the rear case at the bottom.
Follow the guide of opening s HD2 on YouTube there is a factory guide to dismantling the HD2.

Thanks for reply xlr8me. I just check the two brass hinges at the right side of usb connector. It looks fine to me. The other thing i didn't mention on the above post I was flash the dft_leo_nand android after tried all the stock rom from tmobile and the android said "no sim card", i also checked and cleaned the sim slot. Do you think any thing else to cause that problem?
One more thing without the sim or sd card the about phone show up all info of phone: imei, serial..... But with sim card in it just blank when i read the about phone hardware info. Thanks again
Did you try simcard from another carrier?

Yes I did tried the sim from the carrier of the asia country i was traveling to last month, that why i call tmobile to get the unlock code before i go. When i was there and inserted their carrier's sim and it won't work, even when i get back to U.S. I been tried either tmobile or at&t sim too. The phone radio won't turn on. The rest is working ok except those above error messages "A problem has occurred with device.exe" and "Credential.exe".
Do you think i can reflash with WWE rom .50 radio instead of tmobile's official rom?
Thanks
htcphonelover,
You will have to reset the phone back to default rom from htc website. You may also need to reformat sd card but the radio should still work regardless of whether the sd card is in or out.
My only concluding thoughts are that if the above fails to work then try a different sim card and still no good then probably something with the motherboard on HD2.
Good luck and update us with any new info..

[Q] No Sim card in phone (Emergency calls only)

Hi,
I rooted my phone using the ultimate s=off guide on this page:
http://forum.xda-developers.com/showthread.php?t=858996
However, with a SIM card in the phone, it says "No Sim card in phone (emergency calls only)"
I've tried both a Rogers and Mobilicity Sim card and they both work in other phones. How can I get it to read my SIM card?
Thanks in advance for any help. I really hope I can get this working.
I'm really hoping for a reply here, because I have a feeling that the phone is damaged and I bought it on ebay.
I flashed the phone with the royal ginger rom and I tried adding APN settings for Rogers, however nothing pops up for me to select after I click save. It is just an empty black screen.
Is it worth it to buy an unlock code from ebay and try unlocking it that way? It looks like to me that the phone is not recognizing the SIM card at all.
If you used the gfree method and added your APN, it should work, unless theres no coverage in your area.

No it did not. As soon as I got the phone I tried putting my SIM in and it did not ask me to input unlock code. So I rooted it using the gfree method and it still didn't read my SIM card. I'm left to believe that I was sold a broken phone, so I'm going to ask the seller for a refund.

yep, good idea. hardware problem that I'm sure the seller knew about
On a side note. Is it possible that the seller did an unroot and reset to factory settings improperly that is what broke the phone? They claim it was fully functional and the seller did do this before shipping, so if that is the case I''m going to make it clear.

That's your best move but first, slide a piece of folded paper into the SIM slot and then put the SIM card in under it so it'll make contact, that's the only way my MT4G will recoginze the SIM. I use regular notebook paper folded once and cut to be about 1/2 the width of the SIM slot and long enough to let me grab it and pull it out so I can remove the SIM.
Try it, it might work. If it does, it's not a big deal, you can return the phone or you may decide to keep it.

Hmm, this is interesting. I'll try it when I get home. I've tried pushing on the SIM with a bit of pressure while the phone was on and it didn't make a difference though. The SIM slot is pretty tight though, do you place the paper first, then the SIM card?
Tried the paper thing and it still didn't work. Going to have to try and get a refund.
You know, now that I think about it, the phone was powered on when it arrived. It was in postal for about a week, could that have caused the SIM to get damaged?

SM-N910F "No Sim Inserted" Issues

As the title suggests, my phone is coming up with "No SIM Inserted" warnings, and forces me to restart two or three times to get the problem to go away. This happens pretty much daily, at the minimum.
Restarting takes an annoying amount of battery and time, so it's a bit of a pain. The SIM eventually works, but it's not a good sign.
Since the card eventually works, I'd imagine that this is some sort of Firmware issue? My internet is horrible, so downloading it from sammobile would take forever. So I thought that I'd come get your guys opinion on it first on whether it's a hardware issue, or a software issue.. I've noticed a lot of other phones (such as the S4) having this issue, and I'm wondering if anyone has had any experience on fixing it?
It's unrooted so it's still under warranty.
Cheers,

First thing I would try is clean the sim card then factory reset with the sim inserted. I had to do this with mine (once) but thought it was just a glitch so never posted about it. After that I'd try another sim to test the handset or replace the sim card if it was the same.
Had this problem in one of my older phones, can't remember which.
At some point your SIM will stop working altogether and reboots just won't fix it anymore.
I contacted my provider and asked for a new SIM and that solved my problem.
I think it's worth getting a new SIM, or at least trying with a different one.

I'm not sure how I'd clean it, exactly. So I just sorta blew on it, and the tray. If it happens again I'll probably just get a new SIMcard.

The SIM is barely a year old, so it's a bit of a pain if I'll have to get a new one. However, it'd cost me nothing to get a new one, anyway.
Thanks a lot for your input. It only started happening about a week or two ago, so it probably is the SIM.

When I had that issue, it was with a few days old SIM, sometimes they're just defective. I know what you mean about the hassle though.

[SOLVED ]Nexus 6P - No service message

Hi all!
I've bought a Nexus 6P in september 2016, worked fine in every part until yesterday: my phone stopped showing signal strenght and says "No service" in the upper left corner of the screen.
I was on a custom ROM (Pure Nexus) but:
- Restoring factory images didn't help
- Restoring the oldest Marshmallow factory image didn't help either
- Erasing cache didn't help
- Switching to 2G and 4G didn't help
- I did a network settings reset, nothing changed
- I've switched to a new SIM card, nothing happened (old SIM card worked well on other phones, like this new one)
- I've never touched EFS partition but my IMEI is still there, so i don't think it's a network problem
So... Any ideas?
Oh man... I was hoping it was just me. This has happened to me too within the past few days, twice.
After waiting a few minutes it came back. It *May* be they are doing tower work. That's what I'm hoping.
I am on Verizon Wireless on the 3.79 radio if that helps add info to the pile. What radio are you on?

I'm on the same radio, latest radio in latest 7.1.1 release, january security patch, as i said before, installing the oldest Marshmallow release (so the first radio released by Google) didn't change anything!
My provider is Vodafone IT, I don't think they are doing some tower work, because everything works fine on other phones and the same SIM card in!
Good day,
Got same issue few days ago, after phone restarted due to installing January security patch. Phone was not rooted on stock firmware 7.1.1 with locked bootloader.
Cellular network don't work at all, if try to find network manually it return: Error while searching network.
In *#*#4636#*#* all switches in OFF position and cannot switch on. IMEI available.
Also when try to make a call(without network of course) it return: Turn off airplane mode to make a call. Of course it not turned on.
I try flash vendor, bootloader, baseband/radio(3.72, 3.78) previous stock firmware 6.0 and 7.0.
When flash cyanogenmod 14.1, SIM card was not detected.
Carrier Elisa (Estonia), bought in November.
Any ideas?
If you're not on Verizon, I would just switch back to 3.78 radio. Flash it manually. Don't see how that wont fix your issue

Hi mate, a friend of mine have a Nexus 6P, we are on the same carrier and the same 3.79 radio, everything works fine on his phone!
So my problem is not radio realated!
Radio 3.79 is also good for other carriers over Verizon.

Hardware problem with Huawei. The gold contacts on your SIM card are not making contact as they should. Likely a problem with the SIM tray.
Eject SIM card and put some scotch (cello) tape over the card to hold it in the plastic tray. You may need two strips (I did.) Now reinsert the SIM tray. All should be well now with your cellular connection.
Added thickness of the tape holds the SIM contacts to the connectors inside the phone tighter when the tray is closed and the problem is solved.
I did this about three months ago when I started having this problem and have been fine since.

I know you tried an old SIM, but have you been up to Vodafone to get a new replacement SIM as the next step? In my experience they are happy to replace at no charge. If Vodafone IT's new SIM doesn't work, just try a 3 ITA or TIM.
had this issue ONCE, and flashing the proper vendor file again fixed it.

Thanks but I've already re-flashed factory image, so vendor is built in the restore procedure!
So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?
locked and unlocked bootloader,
hard factory reset,
flash google factory image and erase all internal storage,
wiped dalvic/cache,
flash vendor image,
flash different radio and bootloaders,
but still no service and no data. i think it's hardware issue and i have no warranty

Axon 7 A2017g b04 Cellular Radio off ???????

Hello,
I just got the Axon on amazon, a 2nd hand one.
I inserted my sim card and there is no way to have the cellular radio on. I did an full wipe twice, swapped sim, inserted a new one... nothing. Signal strength is zero. I tried also to do an emergency phone call (it should work even without the simcard) nothing. It says that I'm in aeroplane mode. But it's not. I did a manual search of the network, it says error while searching for networks... If I select choose automatically it says registered on the network (but it's not!).
I installed LTE discovery and it says that radio is off... I've tried to reset data connection... nothing...
any thoughts ?
I will send the phone back to the seller but if it's just a software glitch I would rather keep it ....

-Look on the back of the phone, below the Dolby Atmos and "do not dispose of" symbols, and tell me what is the model of the phone. It may be an A2017, and if that's the case maybe they installed the wrong modem and erased the IMEIs
-Try putting your SIM on the 2nd slot
-Try finding the phone's IMEI from the system, maybe it is under About phone - Signal status or sth like that.
-Try another SIM
Those are my ideas for the time being. I also remember there was a secret code that you can put on the phone app, it opens a settings app with a bunch of tweaks and you might be able to change something. Just google "axon 7 secret codes" or similar

Hello,
many thanks for your answer...
I've both IMEI available, I've tried 4 different sims in all slots, the situation is the same. I've also found some secret codes,
*#*#4636#*#* and from the phone info tab I says service: radio off ...

Send it back... almost 100% not a software issue
Mine stopped working out of nowhere, the radio that is. I sent it back in and they send me a new one, no questions asked. Although the replacement they sent me may have been refurbished and I set the phone down and picked it back up and the screen was unresponsive after. It turned on but I think the digitizer got unplugged or something because I couldnt do anything on the screen. Yay for mid-range phones?

I've read that you can fix that by applying pressure on the screen, like in the center, then going to the sides or something like that...
The digitizer is the same plug as the screen though, so it didn't get disconnected
