the signal connection is only made when the back cover is on, I believe that the radio antenna is made when the metal contacts inside the bottom plastic back cover are in tact and clean

Have you tried to put a piece of paper behind the SIM card? I have to do that with mine - a strip about 6 mm wide, folded over so it's 3 layers thick and slid in behind the SIM card when the card is inserted to make sure there is sufficient contact pressure.
yeah tried the paper in sim card trick. interesting tho whenever i try to change it to gsm only it wont let me, i wonder if its actually barrred. but won the phone say when i put sim card in ??
Try it in another phone or call the network provider and ask them

Do other SIM cards work in the DS? It sounds like either the phone has, somehow, become 'locked' to a specific provider, or it is being black-listed - maybe the network thinks it has been stolen?

well ive unlocked the phone, and i checked checkmend dnt show up as flagged, but i spose that probably aint totally accurate.how can i tell if its been imei blocked , will the network provider tell me even tho im not the original acc holder??
I had the problem that the sim-card was to deep into the sim-slot.
So maybe you can try to put your sim-card not to deep into the slot. Just enough so the clip that holds the battery can close.

maybe theres a hardware bug, who nos
Hi guys,
Would love some advice. I bought my brother a nexus 5 and he used it for a few weeks. Then one day the signal just shows empty triangle. Won't connect to cell network at all. I tried flashing it to upgrade to newer rom, and even tried downgrade to different stock Roms from Google, and nothing has made the signal come back. I also tried new SIM cards. Didn't work. Then I Took a working sim out of my phone and tried it in the nexus 5... Still nothing. I have no clue what else to do. Is this a hardware problem? Anyone else ever see this happen before? I'll try any suggestions and report back.

Sounds like you have a imei issue.
Open the phone app, dial in *#06#. If your IMEI shows as "0" read this http://forum.xda-developers.com/showpost.php?p=60421668&postcount=26
Sounds more like phone got blacklisted and you got scammed
Thanks for the advice. I'll check into both and report back.
My imei is displaying fine. I checked it online and the swappa ESN check reports it is clean. I also tried opening the back and disconnecting / reconnecting the antenna wire. Still nothing. Anything else to try?
Did you check other sites to check for blacklisted imei numbers? Does the imei in the phone match Imei on the phone box or sticker attached to the back cover?

The Imei Doesn't match the box. When I was taking a second look at the antenna cable - I found something! I think someone repaired it in the past, and probably did a crappy job. On the main board, just northwest of the antenna cable, you can see some traces leading to another component. And along those traces, there is a blob of solder. I cleaned it off with a qtip and some alcohol, still no joy. But glad to at least understand what the hell is going on a little more. I ordered a scrap phone off the internet for cheap, and I'm going to assemble a frankenphone. Hopefully it will all work great at that point. I'll report back.
Got a phone that was fully working, but had a cracked screen for a good price. Swapped in my screen, bam. Problems gone. Thanks guys.
Glad to hear you got the phone fixed. I also have a phone with a smashed screen. Just looking to find a cheap used N5 with a good screen.
I have a nexus 5 "hammerhead" running the latest version of android marshmallow 6.0.1 .
My issue is, the device wont detect any network signal. At first i thought it was a software issue so I downgraded to lollipop and kitkat but the same issue still exist.
All I see is the network provider name, and beside it 'No Service'. I really dont know what else to do, unless this is a hardware issue. Anyone here had experienced the same issue and have it solved? Or am I just going to have to turn this device into a tablet. -___-
p.s. The screen broke and was replaced, and after return of the phone this happened. Is it that the phone repair guy damaged my device?
Plz help!?
Is the imei okay? Are both of the antenna wires properly connected?

yes i can clearly see the imei #. ..and about the antenna wires, yes both are connected but just that the white wire seems abit off. but i tested the continuity and it seemed to work.
The imei is the same before and after the repair?
Did you remove the motherboard and examine it for signs of damage or alteration?

Yes I did. Motherboard checked out ok. Just can't understand why no signal tho. Wifi and Bluetooth works well. And to answer your question, yes imei # is the same.
Also, I was told that the phone fell before the screen replacement and that's when the issue started.
Even if the antenna wasn't connected, it should be able to pickup some amount of signal. If that's not the case then I'll just have to replace the cables and the lower PCB also the speaker area.
Maybe the drop caused a loose connection on the motherboard?
Did you try pressing against the antenna connection points on the motherboard with the back removed?
Well not entirely.. All I tried was checking the antenna wires (which I realized are just the WiFi antennas) and also, tried placing a copper wire in one of the testpoint area that's dedicated to GPRS.
Is it possible that the transceiver may be damaged? Or that's not possible from a simple fall.
Imei is not blacklisted?
Nahh I doubt it. Phone was purchased unlocked was working for a while.. Fell, signal went ..broken screen.. Then once the screen was replaced, inserted sim and it detected sim and also the network but won't gain any bars (service) nor will it detect any other providers.
I would check the imei just in case.
What would I compare that to, apart from what the phone telling me?
I'm registered on the cell network, but no service despite the adjustments of changing the network type or by dialing *#*#4636#*#* and making alterations there.
You can check the imei in swappa.
same problem
same problem with me sim detecting i can see card name but no service in signal bar wifi bluetooh all ok
Pretty wierd

Yeah pretty weird if you ask me. But if you do get a solution to that issue please share :good:
According to Rameeze87, possible hardware issue. Here's the link http://forum.xda-developers.com/google-nexus-5/help/nexus-5-network-signal-wifi-ok-t3310047
Had no idea couldnt duplicate threads, then again it did help to justify the issue.
same
Mine is doing the same thing. Once in a blue moon it will show full bars upon first inserting the sim for maybe three seconds and show provider then drop all the bars and say no service. Dont think there is a simple fix.
Having this issue right now with my wife's phone. Power button broke and was going through endless power cycling so I removed the power button. Got the phone working but will not connect to network. I have checked everything 20 times.
Any solutions?
Sent from my LG-H811 using Tapatalk
Yup.. same issue. Phone fell and no mobile signals since (sim gets detected). Everything else is working fine, checked the antenna wires and they are connected properly... Anyone here who was able to get the signals back?
similar issue here in the uk.
N5 phone worked fine for 2 years with a 3 sim.
i changed the knackered battery and that all works and charges ok.
but the 3 sim now wont work(but it does in my motorola moto g), the only sim that will work in my N5 is an O2 sim ???
why does one sim work but not another, the phone isn't locked to a carrier?....
Have my Z5 since before christmas, was working very well till 7 days ago, suddenly dropped from H+ to Edge, then no network, and its been like that most of the time ever since, do a network search, sometimes it finds all the network, sometimes it finds only LTE, most of the time it cannot connect to a network. when I walk outside I can get a connection, but sometimes it cannot make calls, text or data with full signal on H+, for the last 7 days, if I walk outside by 5 feet away from the house I get a signal, walk another 40feet further I have no signal, walk another 30feet further I have a signal, while I have a Z and a s6 both working fine on H+ on the same network, swapping sims made no difference to the z5, and my sim works in all other phones perfect.
anyone experienced this?

only had a few games installed, and word, nothing other than that, phone bought new in December 2015, 1 week after MM, was using Androplus v22 and Romaur v2 phone sitting on charger, with good H+ signal suddenly dropped to edge for less than a minute, then no service. have the S6's and a XZ here sitting side by side, they all work perfect with H+ except the Z5, swapping sims makes no different, but the sim from Z5 working in all other handset, all sim are billpay on same network

First do factory reset if nothing gets better
Take it to service to check antenna

How they are going to replace a phone with unlocked bootloader and with custom kernel?
Did you flash your phone with full firmware and full wipe?

I did, tried 5 different ftf full wipe everytime.
yea bad move for unlocking, certainly wouldn't go with my current provider again, regardless of unlocked bootloader, they have no intention of replacement.
I just checked the antennas they are fine, only thing I see different is with or without the grey antenna wire connected or not, it made no difference to the signal, sub antenna looks perfect and main antenna look perfect too. there's nothing to is just metal contacts.
if the fault is not the board then it be down to software, the phone works in area with good signal, in town and city I get 4g+ and download speed is great, but upload speed still poor, would it be the ic on the board?
PS. the Z5 is much easier to open than anything else I worked on before
maybe a silly question, but should I unlock the simlock first before I unlock the bootloader? this is my second z5, first z5, a week after bootloader unlocked, no network, no sim work in it, no TA backup but it does work in area with strong coverage, even on 4G+ with full signal
bit worry to do anything with the new one now
Hello,
I have a big problem with my OnePlus One: After it detects the SIM and I entered the PIN the phone isn't getting any reception. I tried multiple SIM cards. I am actually having a IMEI, tried all APNs, which are available by the providers and I even tried multiple ROMs (I have no problem with erasing data or so, 'cause it's my backup OPO)
But in each single ROM the One isn't getting a signal.
In the settings I can actually choose the providers so the chip/ module ist working (maybe interesting to know: I repaired the phone's screen, so of course i fully dissembled the phone and first i thought maybe I cracked some parts, but the motherboard of my normal OPO is working fine and gets reception WITH all of the parts from the backup phone. In the other way the "not working" motherboard is also not receiving reception with the normally perfect working parts.
So there are only two ways:
Some software isn't working perfect, especially the modems' one, because I can't connect to any network. (I already typed in "+#+#4636#+#+ to see if the phone is getting a signal and yes it does!)
OR some components of the chip on the motherboard broke by the repair, but because it is getting a signal this isn't this way I think.
So I am over. Do you have any hints like a special modem that I can flash?

only resetting to the defaults no, but this should also be done by flashing a ROM to a completely wiped phone.
But now I have done this, but this didn't change something.
Hey,
I have a similar problem but with 3 and 4g. It works for a while then it stops : phone shows full signal icon but I cannot make calls or connect to the web.
However my 2g works fine. Try downgrading to see if it changes anything?

My problem is that I'm not even getting a signal in the notification bar. I am only getting a signal in the hidden menu (call *#*#4636#*#*)
A change between 2g/ 3g and LTE hadn't changed anything and a swap with the frequency via the hidden menu also didn't changed anything.

Make sure the antenna is plugged in.
Worst case scenario, IMO, is that your antenna connector has broken itself from the board at the trace level.

No. It happend a week or two ago. I started my phone in the morning and there were 2 problems: The touchscreen didn't reacted to anytging, but the LCD was working and the signal icon in the notfication bar didn't showed anything. (I didn't use a pin with the SIM)
So I restarted the phone with a long press (about 10 seconds) on the power button.
Nothing has changed so I thought that the cables where loose or so.
I took it apart and disconnected every single connection inside. Put it all together then. Touchscreen was working again, but nothing has changed by the signal.
So as I already wrote:
So I swapped the motherboard with my other OPO and it happend.
So the antenna and bottom part is working.

Check the connection of network antenna again.It might be loose.
Problem solved. It were some "not perfectly working SIM cards" as my provider wrote me in a letter, which came with some brand new SIMs, which are working fine right know. Don't' know why they were all working in the other OPO, but now the problem is solved!
Thanks for any suggestions!

I'd still check it physically. I practically tore my hair out for a few hours after receiving a friend's phone after having its screen replaced. Similar symptoms wherein you can ping for networks, there appears to be signal from the debug menu as well but it just wouldn't connect to a network. I suspect that once it tries to connect and sends the required voltage to do it it fails as the antenna isn't there. The board and the connector itself is a bit of antenna on its own + you may be in an area that has very good reception in general.
