LG H815 Bluetooth won't turn on - G4 Q&A, Help & Troubleshooting

I've recently returned to stock ROM due to the camera issues on any custom ROM for the LG G4.
I've now ran in to a problem where my Bluetooth won't activate, I activate through settings, the button flips to the right as if it goes to activate but switch doesn't turn dark grey and it stays that way.

}
Going to another screen and coming back to settings shows that Bluetooth is switched off.
I've got a logcat dump but I'm not entirely sure what I'm looking for.

I can see it's having errors but I'm not sure what to do about it - is anyone able to help?
Many thanks!

I'm having this exact same problem now with my G4...
Did you end up fixing it?

i think i had the same problem before.. flashing with LGUP using refurbished fix it... or try a factory reset..

then its sounds like a hardware problem.. sorry.

Fix
Do a full wipe.
Flash the stock rom via twrp (20d prerooted).
And then flash stock rom via LGUP or install any other custom rom and it should work. I had this problem many times and this method always worked for me

No signal at all

Hi, I tried to install X-Rome 3.2, everything was ok but I had no signal.
I tried to restart / reinstall / change modem and then I installed Moon Rom.
Still no signal, seems that the IMEI is not good but I don't know how to fix it.
I made an EFS backup before I rooted my phone but my PC crashed and I lost it.

Hey, I found myself in the exact situation. My SIM was fine, my phone worked normally, then only today I realised I could not sen texts or make calls.
3-4 days ago i installed X-Note ROM, not sure if the ROM did something or not. But I restored my stock nandroid image and problem persiste - no service
Would really appreciate any advice form our experts
fixed
So I ended up restoring my EFS image (glad I backed it up) and that sorted my phone out. Nothing else had helped. I thought maybe it was modem related but nope.
If you can't find your IMEI data you may be screwed. Good luck.

Phone stuck on boot screen, bootloader fails

I have my cousin's phone right here - just yesterday he tried to update to Lollipop. He was on stock TouchWiz, no root or anything of the sort and installed the update.
Now, if I try to turn on the phone, all I get is this screen and it just stays there forever:

"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If I try to boot into the bootloader, all I get is this: https://goo.gl/photos/WBSAcHhALQ9Jmz2n9
I really don't know what I would do here - can you do anything once your bootloader is f*ed up?
If it helps, the phone's model is SM-N7505
Yes, the same issue happened with me today on Note3 Neo. I rebooted the phone and it stuck on the same place. Checked in local phone repairing shop unable to make hard reset. They are suspecting of hardware issue. What could be the coz of this?

Try flashing the rom using odin

How would I do that without being able to access the bootloader? I haven't done much with Samsung devices yet, only with my HTC phones. I've heard of the name ODIN though... Are there any tutorials you can recommend?
You don't need bootloader to flash stock rom via Odin, you only need to access Download mode (vol. down+home+lock). You can look up tutorials on YT. Just type "How to flash stock Samsung rom using Odin". Hope that helps somehow

Security Settings Error!!! *HELP*

Every time I try to go to Settings>General>Security on my LG G4 H810 (Stock) the security app closes, and the message "Unfortunately, the process com.android.settings has stopped." appears.

I've tried factory resetting multiple times - it doesn't work.
You should better flash a tot if possible or try a kdz to flash to same version
Dont try other coz there are many dead bodies of g4 lying

Try rebooting into safeboot mode and see if it works there. If it does, the problem may be related to an app you've installed or one that has become corrupted. I would also clear out cache and data (backup first) and reset all app permissions.

Still not solved.Almost all v22 have those problems and can't be solved.

Nexus 5x sensors unavailable

Hey guys!
I recently purchased a 5x off of ebay for $200 and have been largely happy with it. Unfortunately, I've been noticing little annoyances, like not turning off the screen when I put my phone to my face. Not noticing when I pick up the phone, and not noticing when I try to rotate the screen into landscape mode.
I found some other users talking about re calibrating their accelerometers, but I think my issue may be a bit broader.
Testing with apps seems unresponsive on many levels. Using "sensor readout" app all sensors seem to have the same fate shown below. "Waiting for sensor to become available"

I don't know what that means
Edit: Newest n2g47w vendor image installed Still no sensors available
This vendor fits to Android 7.1.2 revision 12 and higher.
Still not working
Well, I just performed a "flash-all" with Google's most recent bullhead release
bullhead-n2g47w-factory-e4179e51
I am still getting "possible malfunction" in the app GPS status and toolbox.
I fixed it! I had installed the
H791-32GB-MDA89E TOT file, and repaired the sensors
Fine

False. I had to reflash the firmware

Bricked TCL Alcatel 1x 5059x

So, I really wanted to get the phone rooted, and I couldn't do it without a recovery, because I can't find the firmware for it no matter what, there is only firmware for 5059d, so when I flashed TWRP for 5059d, it was asking for a password, but I didn't have one. I made one, but TWRP didn't let me mount internal storage. I tried factory reset and it made it even worse, it showed me this image

I tried factory reset but didn't help, then I tried to flash 5059d stock recovery, it worked, but now it does not even want to boot into system, I have tried Wipe data/Factory reset, didn't help. I am stuck now. I did try to flash stock firmware for 5059d, but I can't do it for some reason, SP flashtool throws me some ERROR : STATUS_BROM_CMD_FAIL /0xC0060005) error. I really don't know what to do now, if someone knows to help me, it would be preety cool . This is not my main phone, but I really want to get it fixed. Screw rooting now.
Where did you get the ROM?

First Google search, phone is completely gone though so not worth investigating

Look at this: https://forum.xda-developers.com/t/...rom-a-5059d-to-unbrick.4598953/#post-88676529
May be worth a shot. If I were you I'd first try normally just plugging the usb cable in while the phone is off, and if it doesn't work, take it apart, unplug the battery, and then plug it in
