No service, stuck on airplane mode - Xperia Z3 Q&A, Help & Troubleshooting

Two weeks ago i wnet to a pool and i took pictures under the water wiht my Z3, at first it didnt have ayn problems but then it started to reboot constantly, then my desplay show diferent type of frames.
I thought it was xposed cause i used the workaround method and it reboot some times.
After a restore my phone went well and it appears everything works good. But i didnt have any signal. After a few hours of waiting i turn on airplane mode and then i turn it off my phone had signal and it appeared everything worked good. After two weeks, my phone had lost data i could navigate or connect to mobile data.
I thought it was for reception and laso because i install xposed again. I did a restore and suddenly i didnt have any singal. I tried everything restore, airplane mode... etc. The only thing that worries me is that when i try to call it says that i must turn off airplane mode before. I search a lot about this issue i found one similar thread in xperia support that it happened the same way i did. Also other has the same issue because he upgrade his phone to lollipop.
But thats not all, also it has happened to other android phones but no one has find any solution.
After a few hours of trying everyhting im going to take my z3 to sony on thursday .
If some has some similar and knows a way to repair this is the time to tell jeje.
Greetings

[Q] Connection Problems

For the past couple weeks I have been having major connection problems with 3G & WiFi. It would just stop working, even though the bars would be there and show that it is working, but nothing would load. Normally have to turn off Wifi or data for a couple minutes and then turn it back on, or reboot, but even then it does not last that long.
I found on these forums and other places that people seem to have been having the same issue and was caused by the recent update from SuperSU and something it was giving permissions to called mksh. So I denied it permissions, continued to have problem, I went back to the older version, still the saem, I removed the program, and started using just normal Superuser, and the problem still continues.
I was for sure this was the problem, but the program is gone now. I know it can't really be the mksh by itself because it's part of the android OS. For awhile I thought it might have been my SIM card but quickly realised that well WiFi is a problem as well, not just 3G data.
Any one have ideas about this? It's getting really annoying and almost not usable.
BUMP, anyone, this is getting quite annoying. I have searched and done everything possible.
Still needing help.
I don't like bumping this all the time.
I have done all the searching I can, no one has similar problems, no one has any ideas?
Still looking for some answers.
I guess I am the only one.
service issue
toggle airplane mode and if it works call your provider it sounds like a issue with your service

Click to expand...
Click to collapse
What do you mean by toggle Airplane mode, when having the problem, turn it on, then turn it off, to see if service works again?
Yes that works, that is what I do most of the time, actually most of the time I have airplane mode on, and then have only wifi enabled.
Either way, how does troubles with WiFi as well as 3G connections mean a problem with my service provider? They don't provide WiFi
Anyone..

[Q] No carrier signal - damaged HW after L update?

After updating to 5.0 my Nexus is kind of stuck in airplane mode.
I usually turn to AP mode at night. Yesterday morning, I turned AP mode off, but I didn't get any carrier signal. The AP mode icon is not there, but when I try to make a call, I get the "turn off AP mode" message. Wifi works fine, but I can't make any calls or receive messages.
First time it happened, I removed the SIM, rebooted, put it back in, and it was back. This time, it doesn't work. I tried another SIM to no avail. I even rooted, did a full wipe, but the problem persists.
Any ideas?
Solved!
I flashed all of these modem images:

Should have done it in ascending order and not from the newest, as only the second one worked, lol
EDIT:
Not.... signal is gone again and I get random crashes. Trying to install vanilla Lollipop.
I tried everything I can think of. Even reverting back to KK. Still, no signal. I got some the other day, but soon it disappeared. It's probably a HW error, sadly :crying:
Is it possible that my antenna was damaged because of the L update? Am I the only one who has this problem?
Can you check your IMEI in About Phone => Status? It may be that your IMEI was lost during the update.
I already relocked the phone and sent it back to the seller for a reclamation. Hoping to get a new one by Xmas

[HELP] 5.1 Suddenly WiFi, ADB, roaming don't work...

So I've been in a happy relationship with my rooted, stock rom/recovery Nexus 5 for a while now. I updated to 5.1 the other day through ADB without issue and everything has been working fine until I took a plane to France (I'm originally from Spain) a couple days ago for the weekend.
First thing I noticed is that roaming didn't work. No matter what I switch on the phone I get network but no data coverage. I checked with my carrier and everything is right on their end. I switched SIMs just in case and it's a phone issue.
The next thing, WiFi doesn't work. When I go to WiFi through quick settings it's always toggled on, searching, but never getting any results. However the icon appears as WiFi off. When I go to WiFi through general settings, no matter what I click, it appears as off and with no results.
I thought about reflashing radio, but when I got to my hotel room I discovered that ADB wasn't working. ./adb devices throws no result. Plus, Android File Transfer (I'm on a Mac) doesn't work either. USB charging works just fine.
Next option would be to restore the phone to factory settings and go from there, but I would rather not use that option before discarding all the others. I have my TB backups in order, and the most I would loose would be a couple pictures.
Any crazy ideas I can try? I'm flying back to Spain in two hours so when I land I will discover if I have data on my home network or if I don't. In the meanwhile, I'm going to be on a plane with my laptop, a USB cable, my phone and a lot of time to try things.
Thanks!

Nexus 5 WiFi Crashing Phone

Hi all. I have a weird issue that after Googling it doesn't seem anyone else has had.
The issue started earlier today, in the morning. I was using my phone on the WiFi and it was working phone, then my phone crashed, restarted itself.
I noticed it wasn't connected to the WiFi, went to the WiFi settings and where it usually says the list of networks it said "Turning on WiFi" and the slider at the top was greyed out so I couldn't turn it off.
I tried airplane mode and that didn't help. But the phone was working fine on my mobile data so restarted.
Now the weirder part starts. I basically have an issue where, if I turn on the WiFi, my phone crashes, or doesn't act like it's turning the WiFi on.
Even going Settings and then pressing on the WiFi option freezes the phone.
The problem started when I was still using 4.4.4 however since the problem developed I've used my mobile data to download the updates and now have 5.1.1 I think.
The problem persists even after updating to the most recent version and doing a factory restore. The phone is currently completely stock with nothing downloaded on to it. All I did is go through the first time setup for the device.
The WiFi currently is off, and the phone is working however it won't connect to my data, it has the signal bars and then an ! instead of a 4G icon.
If I try to turn the WiFi on it crashes the phone.
The phone is still under warranty so I plan on contacting LG on Monday however it's currently 3:34 AM on a Sunday so I have a day until I can call them and was hoping for a solution in that time.
Thanks in advance. I have the phone to hand so anything you want me to test I'm able to.
There is some information I didn't type as I don't know what is important was trying to avoid a wall of text so if you have any more questions I'll answer I best I can.
Thanks for reading, I hope you can help!
