[Q] No carrier signal - damaged HW after L update? - Nexus 5 Q&A, Help & Troubleshooting

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

Installed CM 10.2.1 and now have no service

Okay so last night I installed CM 10.2.1 on my Samsung galaxy S3 (Verizon SCH-1535)
Everything's running smoothly but for some reason I don't have any service anymore
I'm using a Family Mobile SIM card and APN, still have my IMEI and MEID but in the phone status screen PRL version, MIN and my phone number show up as unknown. Also it says that my mobile network state is disconnected.
Right now I can't send texts and call anyone. However I still do get automated billing texts...
Not sure what to do right now. I still have a CWM backup of the stock ROM. I'm rather new to this custom ROM and bootloader thing so I'm worried that I'll accidentally brick my phone.
Nevermind, i fixed it!
What did you do to fix this? I've had almost the exact same experience over the past couple of days but haven't managed to recover my service.
Background: Flashed back to Alliance 23 (TW 4.3) to see if TW would solve anything and it didn't. I've flashed the ML1 modem and NE1 and still nothing. I even went to a Verizon store to replace my SIM in case the PRL got botched somehow. I can receive texts and send texts sometimes but not consistently, cannot make or receive phone calls.
On Alliance I have the CDMA/LTE/EVDO network mode selected (defaults to global). I was previously trying out CM12.1 and had issues with the modem type sticking to LTE/CDMA (auto prl), after reboots it would switch back to LTE/GSM and the network modes presented were LTE, 3G, and 2G which didn't seem right.
The last time I had a fully functioning radio was with SlimKat Stable. Was having issues sending/receiving MMS and figured it was time to upgrade so went to CM12.1. Since I've tried flashing Alliance and other versions of CM I don't think flashing back to SlimKat will do much but I guess that's next on my list..
I feel like I'm missing something simple. Anyone have ideas?

I may have managed to fix this. Remembering the IMEI issues that happened early on in this phone's life I figured it might have something to do with that.
My IMEI was correct in my phone status, however my phone number and MIN were not correct (phone was 000-000-0023 or something strange) and my MIN was 00. Something definitely broken there.
Steps:
It requires you to have an IMEI backup already. I had done the reboot nvbackup from adb ages ago and decided to give it a shot with a reboot nvrestore.
Phone rebooted but was stuck on the Samsung logo...uh oh.
Had to do a battery pull and reboot to recovery manually.
Restored Alliance 4.3 backup and voila! Full service, phone number and MIN were correct.
Restored my CM12.1 backup image I had been trying out. Right off the bat there was still the same issue of no service.
Dialed the phone info menu (*#*#4636#*#*) and changed preferred network type to CDMA only, ping test succeeded.
Went to Settings | Mobile Networks and things looked more normal which was a great sign. My Preferred network type was actually blank, so I selected LTE (recommended).
Tried a test call to #832 and success!
Rebooted to make sure everything sticks and it does.
That was not a fun experience...still not entirely sure what actually broke but I've got a usable phone again and to top it off it's on CM12.1 which is just awesome so far

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!

"Turn off airplane mode to make a call", radio not working

Hi XDA!
I have a problem with my OnePlus One. I have no signal on it and when I try to make a call, it shows me "Turn off airplane mode to make a call". It must be something with the software. I tried huge some ROMs (stock, custom, KK, LP, MM, even ColorOS), many firmwares, modems etc. but nothing helped me. I was flashing with TWRP 2.8.7.0.5, 2.8.6.0 and 3.0.0.0 with no effect. IMEI in my phone is correct. Both WiFi and Bluetooth works. Only the sim card/signal is a problem.
I cannot "Turn on radio" in #*#*4636*#*# -> Phone info. And here's what's there:

I hope you will help me, because I'm out of ideas for this moment. Of course I have "equipment" to flash: unlocked BL, TWRP, fastboot.
Thanks in advance!

Thank you for your answer!
Sadly, I tried it before without success. Now I've tried with few other CMs and other TWRP, but still same. What I have now is: http://i.epvpimg.com/Zdcnh.png
Funnny thing that one time it somehow had signal (a bit weaker than it should and without network).
Solution
I had an identical dilemma this morning. After talking to my insurance, filing a claim, going to my carrier, having a tech look at it, and convincing the corporate office to give me a new phone, I was messing around and decided to try to restart it again.
This time I turned airplane mode on. Then powered off and restarted. Upon powering back on, I was prompted to allow airplane mode to remain on or to shut off airplane mode. I shut it off and service resumed immediately. I hope this helps.
Hi - Few months ago, I upgraded my OnePlus 3T to Lineage 18 and Android 11. today I inserted a SIM card, but I am getting an error "Turn off airplane mode to make a call" Radio Off.
I tried to WIPE/ Clear Cache in TWRP. please help to resolve the issue.
did you solve the problem somehow?

LG G5 Sim not detected only for SMS and calls

As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.

Sudden and persistent "emergency calls only"

Randomly, earlier today my Galaxy S7 went from having signal fine to being unable to successfully connect to a network.
The problem is not the SIM, as I tried my SIM in another phone (fine) and a working SIM in mine (no luck). I even tried a different network but no luck.
The problem survives a reboot, and I tried resetting the network settings. I also tried clearing the cache partition. I haven't yet tried a full factory restore.
I'm on the latest S7 firmware - I'm a beta user for the Android 7 firmware.
Anyone had this issue and know a fix? It could be hardware but I'd find that a bit odd... I suspect something software is going on, as it detects the SIM fine, and shows a signal that fluctuates, it just seems unable to connect properly...
Thanks!
Resolved... turns out the phone I got 2 months ago (from CEX) had since been blacklisted - and it kicked in yesterday. I took it back to them, they're raging but I got a replacement!
