No signal - Nexus 5 Q&A, Help & Troubleshooting

Today I received a phone recharge, and the first 5 minutes after this recharge everything was good, but then, with no sense, my smartphone didn't receive the signal.
Like I said, the first 5 minutes the device is good, in fact I called my friend with no problems...
I tried to change the SIM, but it doesn't work anyway...
What can I do?

Assuming the reprovision didn't work and you can confirm its not the SIM card damaged.. You could always flash a different radio in recovery or return to stock 4.4.4 via factory image to verify its not the software it'll also flash the latest stock radio.

Unfortunately my pc doesn't work, so I can't do nothing for now, there are other things that I can try?

Mmm... can I restore the nandroid backup of two days ago, when the signal was received perfectly?

Of course you can restore the nandroid. I'd do a full wipe first just to make sure everything is cleaned up.

Ok, now I try to do wipe cache, wipe dalvik cache, wipe data wipe system and then a restore, thanks.

Flash the factory image in fastboot and see if that solves the problem. If it doesn't it could be a hardware issue.
Edit, I see you don't have a pc Can you borrow one?
Sent from my Nexus 5 using XDA Free mobile app

Today I'm gonna send it to repair, I hope that I can have the pc as soon as possible...
Anyway, in the hardware problem case, can I send it to LG?
I don't have the Google warranty...

Also tried to flash the rom's update, but it still the same.
So my last hope is to flash the factory image, but I have no pc at the moment.

Install Philz Touch. Wipe all partitions and flash vomer's stock 4.4.4 rom via recovery. This should be enough in most cases to rule out a software issue. But I agree, fastboot cleaning has solved my problems which recovery wipes couldn't!

Ok, thanks for the suggestion, I'll try it when I recover my pc

If you didn't mod the system files then the original owner did. To resolve, flash stock factory 4.4.2 images. If you did a factory reset when you got the phone, and don't want to start over, flash the img files one at a time with fastboot (excluding userdata.img).
If you don't know how to do that, check out the stickies (I think in general). There is a very detailed thread there.
The phone was brand new when I got it. I believe it said update ready for download when I did the factory reset.. Now it just says that..

you can take the ota update through wi-fi only...
no need to reset. but i prefer to do it to prevent any system app from crashing and to have a fresh firmware.
All you had to do was connect to wifi. That update required you to do that. "Via wifi only".

Oh. Thats odd, but I guess you got it working, so thats good.
Your screen shot shows that your not connected to Wi-Fi. It says you have to be connected to Wi-Fi to update.

[Q] sim card

My nexus 5 will not read any sim card at the moment. I flashed back to stock 4.4.3 and ever since that, no matter what carrier sim card I put in, I get no call reception. The phone is recognizing there is a sim in because I flashed a custom ROM and whenever I put in a sim from T-Mobile,att, etc., there APN settings come up. I have no idea what's going on. I am no noob. Any suggestions would be greatly appreciated.

Restore a nandroid if you have one. It should fix it.
Flashing factory images didn't help me to recover the network signal and to detect the sim card.

Yes it's possible. Are you trying to just return to stock/another rom or do you want to flash back your nandroid?There's an easy way to flash zip files through twrp easily. *adb sideload*

I've tried that... No dice. I've tried everything. At this point I'm guessing its hardware. Although it doesn't make much sense that the phone is recognizing there is a sim in just will not connect to a network. This is a major bummer.

Yep. Same thing happened to me. It would detect my sim, it would connect to WiFi, but it wouldn't connect to mobile data. I flashed almost everything I could find and nothing worked. Just RMA it.

Unable to mount /sdcard0

Started having an issue with dirty unicorns so I went to wipe in recovery and I tried installing a new rom and it failed. Next time I tried wipe it says unable to mount /system. Tried mounting sdcard0 and same issue, unable to mount /sdcard0. Haven't hooked up to PC yet at work all day. Any ideas? Will upload logs after work. Any help would be great using backup phone that's half busted. Thanks!!!

You might have to Odin flash the stock firmware. Sdcard0 is the internal sdcard. It might be hardware failure. I'd flash the stock firmware and see if you still have the problem

Just a question: flashing the factory image will delete my nandroid backup, right?
If yes, I can save a copy of the backup in my pc and paste it in the device after flashing the factory image and restore it?

The factory reset would also have deleted your nandroid if you'd done it from stock recovery like the thread says.

In fact I see this after the factory reset with TWRP, anyway I can do what I said in the last post?
To flash the recovery stock I simply use the command fastboot flash like I was flashing the factory images or I have to do anything else?

Flashing the factory image will wipe your device if you use the flash-all bat. Copy your nandroid to your pc. You can copy it back after you re-flash install your recovery

[REQUEST] Upload of the latest AT&T update

If someone running the latest AT&T update, IIRC 21p, could take a nandroid and upload the system, boot, and modem partitions it would help me out a lot.
Don't have a PC at the moment so I can't go back to stock to take the OTA for fear of losing root and custom recovery.
Preferably with no debloat or changes other than root (or Viper )
Thanks.

Try taking out the SIM card and checking for the update on WiFi after a couple reboots. Works for me every time, of the update is 100% available.
