No signal. Need to get in airplane mode first - One (M7) Q&A, Help & Troubleshooting

I have this weird problem for almost a half year now but now it is getting realy annoying.
If I reboot the phone and enter my pin I don't have signal. The bars shows a X.
But If I enter airplane mode on and off and re-enter my pin, the signal comes back.
It only happens when I reboot or shutdown my phone.
This problem is on every custom rom. ARHD, Insertcoin etc. etc.

This will most likely be down to your firmware or kernel. Installing custom roms will have no effect as they do not include firmware or kernel.. can you post a fastboot getvar all minus imei and serial number

[Q] Flight mode activating on random intervals

i am having a very annoying problem with my phone, i have just done a clean install of darkys 5.6 rom and every so often the phone will enter flight mode, the same thing happened in doc's rom. i have tried flashing other roms but still flight mode will activate,
is there any way to force disable flight mode or should i just send my phone back for repairs
please help
Can you check if your IMEI is still valid and correct? Compare it with IMEI sticker on the box your phone came with..

[Q] Phone is in a reboot loop with no radio signal

I've tried flashing numerous ROMs and they all boot up then proceed to restart about 30-45 seconds after doing so. When the phone turns back on, it just comes up to a black screen with nothing but the wi-fi signal, radio signal(which receives no signal), and battery icon at the top of the screen. It'll continue to reboot after 30-45 seconds on this screen as well.
Now I can access my settings on this screen if I pull down the the tab from the top. When I go to my phone info, the MEID,phone number, and IMEI among other things are "Unknown". I have tried clearing cache and doing a factory reset but it doesn't help.
If it helps, this is an HTC One that I bought from Ting so I was unsure if this should be here or in the Sprint HTC One subforum.
I just want to get this phone back to how it was working when I first got it. What do I need to do?
Did you figure it out
Did you happen to figure out how to fix your phone? If so please post how you did it
If it is a CDMA version it was flashed with a GSM ROM (could be vice versa as well). Only an RUU fixes it. I had a friend flash a GSM ROM to a Sprint and it was the exact same symptoms. Black screen, no IMEI, reboots.. no ROM flash will fix it.

[Q] Htc One m7 -wifi stuck "turning on"

Hei guys !
I have a htc one with unlocked bootloader and s-off.
Yesterday my phone started to experience some trouble with the wi-fi connections. When i turn on the wi-fi it remains stuck on "turning on" and i can't turn it off anymore. I tried to more options by clicking on the 3 dots in the right corner but no succes..all options but "Advanced" are greyed out.
I already tried to flash a custom rom (Viper rom) and reflashed stock ruu and the problem persisted.
Any of you experienced similar problems?
I had that problem on another type of phone. It was hardware. You've already factory reset and changed the OS. The only other thing I can think of is to pull the battery (and you probably don't want to do this yourself). Good luck. I would send the phone in for warranty repair, if you can.
Unfortunately i can't rma the handset for repair because it was bought second hand.
I thought maybe it was another way to resolve this issue.. I found it odd because while i was using the device over the wifi connection it just disconnected and would not connect back on. No other glitch , fireworks or nothing..
Same problem here,
it suddenly stopt working.
it trying to connect and stays there.
reboot is fixing it for a few minutes and problem is there
again.
i have the problem on multiple networks.
new firmware flashing didnt help,
new OS didnt help,
new Recovery didnt help...
I have the same exact problem.
It did turn on randomly one night after restoring a back up. Stayed on all night, gone in the morning.

Im on ViperOne and the problem is still there.
I Wil go back to stock soon and try if that helps. Don't think it will cause I think it's hardware related. But have to go stock when I want it to sent in for warranty.

I bought a brand new second One M7 and flashed a backup from the "old" one. WiFi is working.
Running ARHD with experimental 14.11 I did a factory reset within TWRP 2.6.3.3 recovery on the "old" One and until now WiFi is already working for a day.
I thought it was hardware related but why is the "old" One working again....
And why is the new One has working WiFi with the exact same copy of OS....
Strange
Edit,
The "old" One WiFi stopt working.
Suddenly it was gone.
Going back to stock with that one and sent it in for repair.

After a lot of sending and receiving, the phone stayed at HTC and they sent me an m8 for the inconvenience...
Ok. So I can't tell u guys what the problem was.
Hola, I seem to have a similar issue to the OP. After flashing a 5.1 GPE ROM, wifi never worked again.
I tried different ROMs, different TWRP, different firmwares, and even reformated partitions using mkfs.ext4. Wifi still stuck at "Turning on..."
Do you guys have any ideas? Thank youuuu!
Try going to the root folders and delete the wifi folder from data/misc then restart the phone. Might work.
After running the command below on Maximus HD 46, I was able to turn on WiFi, but the connection would be unstable, with the adapter often turning off and on.
Code:
su
restorecon -FR /data/media/0

I tried removing wpa_supplicant.conf. Tried removing the entire folder, connection still resetting randomly.

Hello. I have created an account here just to share how I fixed this problem because I couldn't find that solution posted on any forum. It might be helpful for someone, but also I might have been the one that caused the issue in the first place. I have a rooted HTC One M7 running 5.0.2.
So, the "Turning on..." for me occured once my phone's battery completely drained. I have plugged the phone in the charger and it displayed 0%. Once the charge level reached 1% I turned on the phone and almost immediatelly turned mobile data off and wifi on. It was then when it got stuck. I have tried almost all the accepted solutions and none of them worked. As I didn't have time to keep trying to solve the issue I left the phone as it was, not trying to connect anymore but saying "Error" under Wifi in Settings.
I thought about what might have caused this and remembered that I have recently tried to use my phone as a wifi extender using the app called "fqrouter2". Within the app there is an option in configuration "Disable Wifi P2P" that should be, as recommended by the app, disabled if the app failed to work. I have, of course, tried it but it didn't work anyway. I have uninstalled the app and that was it. Wifi worked fine until my phone died. So I decided to reinstall the app and try the "Restore Wifi P2P" option. After restoring it I uninstalled the app and power cycled my phone. When it turned on wifi started working again as if nothing ever happened.
As I said, I might have been the cause of the problem in the first place and I doubt somebody had the exact same situation as mine, but I'll leave this here, just in case. Cheers

[Q] LG G2 Cell Radio stuck OFF

Hello XDA,
I have an LG G2 on Verizon that is showing the cell radio being off. I am not sure how to get it back "on". Antennae wires are on perfect, just not showing any cell signal on the signal bar whatsoever.....phone was give to me from a friend and I assumed I could just fix it! When I go to make a call it says " Airplane Mode on" and when I select to shut if off, it not being on in the first place, nothing happens. I have tried to use Toggle Cell and Cell Radio Shutoff and neither works, the Cell Radio Shutoff actually stops in error.
HEEEEELLLPPP!!!!!!
Bought a phone off ebay and have the same problem. Have you found a solution yet? Mine reads the sim card, but no reception to make a call or connect to data. I'm thinking its a hardware issue or the efs got jacked up.
I have this same problem on att note 3. I have not found a solution yet. No pattern, just the phone may, or may not boot with radios on. Grrrr
would be willing to bet that someone flashed a ROM that is not compatible with the radio - they need to match. TOT it back to factory stock and try it.
So. I've gotten service back.
What makes it work is to make sure airplane mode is off and turn off the phone from 5 - 100 minutes.
With one ROM, firekat, I was able to boot a few times with radios on if I left the phone off for 4 minutes. This new ROM seems to take longer. I ended up leaving it off over night and it "works" now :/ would like a better fix.
98% of the time when I boot up airplane mode is on and the radios can't be switched.

Actually. It works if you make sure airplane mode is on, I turn it off and on with tasker and secure settings. Leave the phone off for 10 minutes. Boot it up. Airplane mode should still be on, turn it off, and voila. Service.

No Sim detected, No Wifi

A few hours ago my phone lost signal, I thought nothing of it at first as there is a dead spot close to my home.
Now I noticed the WIFI is also not working, and I cant switch it on, the toggle just jumps back to off.
I reset the phone, removed and changed sims, and did a factory reset. Nothing fixed it.
The phone wasn't dropped or anything.
Any ideas?

If I hold power+ up I get a message saying "no Command" but I cant do anything.
Did you try the test mode : *#*#4636#*#*
to test some functions ?

No, I cant get past the setup screen after the reset, as I cant connect to anything.
I think the only way to fix it is to flash it somehow. I guess the radio is part of the kernel, does anyone know where I can get the stock kernel to flash?
Why don't use the warranty ?
I bought it off gearbest, so think the warranty is going to take a long time.
But maybe it is the best option. I'll at least find out what the procedure is.

I'm not sure but maybe you can ask to gearbest and to xiaomi directly in your country before any other modifications on your phone
Same here straight out of the box in Sweden global version ?
It usually is a kernel problem. Flash trough fastboot the rom if you can and see if it fixed.
Maybe your persist pertition got corrupted you have to flash it manually. Or if you have warranty then just claim it.
I'm having the same issue :/ Any update on this topic?
