U12+ suddenly had gsm bluetooth and wi-fi stopped working - HTC U12+ Questions & Answers

Hello,
So basicely my GSM, bluetooth and Wi-Fi stopped working suddenly. I have done nothing particular to the phone. He had an OEM ROM, just relocked the bootloader 5 months ago.
I tried to ON/OFF airplane mode, then Reset Network settings, then reboot to Safe Mode, then Reset entirely the phone, then flash a ROM with 2Q55IMG.zip technique but it stil doesn't work.
Do anybody have an idea ?

[Q] [i9023] Stuck in desk cradle and landscape mode

Starting this morning, my Nexus S is stuck in landscape mode.
When I fist boot up the phone, it seems to launch directly to the desk cradle mode, but it has never been connected to one.
Everything is landscape even the launcher. I can't use the phone because I can't reach the OK button for the SIM card PIN enter screen.
Factory reset didn't help. The inital setup is portrait, but after that it reverts to landscape.
Any ideas? Might this be a hardware problem?
EDIT: Android 4.0.3
EDIT2: I applied the VQ8PQk_V.zip OTA update manually to my stock 2.3.6 version. After a factory reset, the phone works as normal until the first reboot. The accelerometer is still working, i tested it after a factory reset before rebooting the phone.

Sorry me for waking up this thread from his graveyard after 3 month.
I have an i9023 with the same issue of Tocharius:
my device is stucked in landscape mode and when i try to turn on it I cannot enter PIN code because OK button is outside the screen. The only way I have to make it works is to wipe data partition and everything works fine until first reboot.
In addition to this problem fastboot has stopped recognizing my phone, while ADB still recognise it.
When the issue firstly appears I was under CyanogenMod 9 v6.0 (Kalimocho).
I tried to flash other ROMs, but nothing has changed.
I tried to revert to stock, but nothing has changed.
I tried to open the phone, clean every connector i found, but nothing has changed.
Someone can help me?
I got this problem too. Lately I installed CodeNameAndroid 2.0 http://forum.xda-developers.com/showthread.php?p=25941996#post25941996 and after reboot my phone got stuck in landscape mode. I tried to reflash the rom and everything was fine until a reboot. Wiping data and resetting factory helps until reboot. I flashed another rom http://forum.xda-developers.com/showthread.php?t=1588799 and again the phone was stuck in landscape after reboot. I tried all rotation settings but nothing changes.
I was browsing settings searching for something that could fix it and turned adb debugging off and on and now it is stuck in portrait mode.

Nexus 5 wifi stuck on turning on

I was using my rooted Android 6.0 with that kernel chainfire uploaded here on xda with the supersu 2.52 beta, and it was working fine for a few days until my wifi started to stop working, turn off, then turn on after a few seconds, lag, reboot, turn off, on, off, on until it stopped working. Putting the phone to airplane mode then back to normal or safe reboot could get it work for 10 minutes and not every time.
Solutions I have tried and didn't work:
Reflashed android 6 without wiping data
Factory Reset android 6
Flash 5.1.1 with wiping data
Clear Dalvik Cache
echo -ne the .macaddr file
delete the wpa_supplicant files
Nothing worked. When I dial *#*#4636#*#*, wifi state shown "UN-INITIALIZED"
What to do! I need to fix my wifi and can't afford a repair shop, and I'm out of warranty and outside the US so can't return it.

I just started to have the exact same issue last night. Wifi won't come on and if it does my phone reboots. There is a thread about it on Google Nexus help forums: https://productforums.google.com/fo...ification#!msg/nexus/yx5kGasv2lE/Pbx5KNQjCAAJ

Nexus 5 WiFi problem with Marshmallow
Hello, after updating my Nexus 5 to Android 6.0 the Wi-fi is no longer working. It keeps trying to connect but never actually turns on the Wi-Fi or show any networks. I've turned it on in Safe Mode and it still has the same issue.
Please help!

I tried that but didnt' help. Almost every time I turn the wifi on my N5 eventually reboots. I did have wifi connect for a few minutes today to my 5Ghz wifi but then failed for no reason.
I am guessing the wifi chip has burnt out or its some other hardware/software problem. My N5 is a day 1 shipped phone and had no other issues with it. Such a bummer....

So its probably not the same issue. Did you tried all bands? Is it doing the same thing on different rooter brands?

S7 Tmo Wifi and Bluetooth suddenly stopped working.

The wifi and bluetooth on my s7 Tmo suddenly stopped working. Its running nougat, network unlocked and has root. I rooted following this thread: https://forum.xda-developers.com/tm...eres-how-rooted-nougat-s7-edge-g935t-t3567502
Everything was fine after rooting and I was using it for a while but suddenly, those two functions stopped working: Bluetooth cant find devices and other devices cannot find the s7, the bluetooth switch turns on but it seems that's just cosmetic.
The wifi switch isn't even working at all, The wifi is just not starting. It tries and fails.
Please help. I've tried different solutions like deleting this file: data/misc/wifi/wpa_supplicant.conf and restarting, downloading wifi fixer apks, clearing the cache, master reset, installing 2 stock roms, the oreo update and the nougat, nothing as worked.
Please help.

HELP MY PHONE CAN'T CONNECT TO WIFI!!!!!!

So I just finished rooting my OnePlus 7t Pro and when it turned back on it won't connect to the wifi. Everything worked fine before but now when I flip the wifi switch to "on" it plays the animation but stays in the "off" setting. I've tried to look online for help but everything is from years ago and no longer relevant on android 11. Help please this is my first root attempt.
1. Wipe /cache partition
2. Forget the Wi-Network ( means remove Wi-Fi network from saved networks list ) and reconnect
3. Switch off Bluetooth

I've tried to turn off the phone then press all 3 buttons to get it into fastboot but instead it just does the bootloader thing again and wifi still doesn't work. When I was installing a driver on it I couldn't find the one that matched my build number exactly so I got the next closest thing. Could this have something to do with it?
It should be obvious to you that when the phone is started in Fastbot mode (AKA Booloader mode), the Android OS has not been started at the same time, so Wi-Fi cannot work.

I know that but after going through bootloader mode it restarts like normal and goes back to the home screen. At this point I go to settings and proceed to switch the wifi on and the switch does the "switch on animation" while still staying "off". I did in fact delete all previously known wifi information and managed to wipe the cache partition.
