[Q] Stuck in boot loop after enabling second screen in developer options.

While attempting to get HDMI working, I stupidly enabled second screen in developer options in my aosp ROM, which immediately rebooted the phone. I'm now stuck in a loop whereby the phone boots and then restarts when loading the lock screen (presumably it's enabling the second screen).
Is there a simple way of resetting settings to default or bypassing this during boot? I'm away from home else I'd wipe and recover, so any help would be appreciated.
I'm using teamwin recovery if that's relevant.

Try clearing cache, if that doesn't work restore backup.

I think there is a safe mode, not sure how to activate it.
Also, factory reset is possible.

It can be activated only once the phone is booted afaik.

Thanks chaps,looks like a recovery cache didn't work. Lesson learned!

So you got out of boot loop or what?

Sorry, to clarify clearing cache didn't work. I ended up wiping and recovering.

I know this is an old thread but I think I found a solution.
If you wait until the boot animation is already showing and then hold down the buttons like you were trying to boot into recovery it should boot your phone into safe mode. Then you can go into settings and disable the second screen. It may be different on the one x than on my phone though. I have a note 2. I am just trying to keep anyone else who has this problem from having to wipe their device unnecessarily.

[Q] How to enter recovery mode using key combination?

I can use "adb reboot recovery" to enter TWRP 2.7 recovery mode, but I want to use key combination, please tell me how to that.

Hold Power + Vol Down > Wait until LG Logo pops up and release from both buttons > quickly hold Power + Vol Up + Vol Down again
It will pop up with some message about reset to factory settings, but it's all a bluff.
Hit Power x3 times to confirm and you'll get to TWRP recovery

Thanks, it works.
actually I enter this factory reset mode before, but i just don't know it a "fake".

so will this erase all data or not?

That will depend on whether you've installed TWRP or not.
If you've still got the original recovery it will wipe it like it says it will, if you've got a custom recovery it will take you to it.
The standard recovery isn't a recovery like you're expecting it to be, if just has a way of resetting things to default without allowing you to do anything extra. OEM don't like giving people options but want a way to reset to defaults that the customer can use before needing to return a faulty unit which might not be faulty. If that makes sense.

From what I can tell, it's not a "bluff". It seems that the stock recovery partition would just automatically do a factory reset, so it warns you before booting the recovery partition. Seeing as you're non-stock, it just boots into TWRP/CWM. It's a valid warning that's simply set up in a weird way.

You don't.
We'll you might be able to but you're going about it the wrong way.
First you need to find the right forum for your device, then you read, followed by more reading.
At some point you've hopefully discovered that you should have done all this reading before you reset your device.
Also before pressing the post button on your next post, read it first to make sure it makes sense.

Thank you very much, I tried other combinations found on some web pages that failed. This one worked!

Issue remains.

I got myself in a pretty bad situation. I have the stock rom. I am trying to get that back using recovery but it's not working. Only factory reset screen. This tablet stopped working in 2015. It cannot write ANY data ANYWHERE. Can't take pics, Can't take screenshots, Can't download apps. Nothing. I really want my tablet back... :/

I'm probably not the best person to help, however if you put a new post up with more details on what you have access too, the community will be able to help out.

Install LG software on your computer first. Then with the tablet completely off, hold VolUp and plug the tablet into the computer. That will enter LG download mode. Use the LG software on your PC to install the latest firmware available for your device. From there you can use the guides on this forum to go custom if you so desire.

[Q] Unfortunately,the process com.android.systemui has stopped.

Okay, so I have a rooted, stock 4.4.2 G pad. I was never able to successfully get a recovery and I have no backups. The issue started when I used G2 xposed and I changed the multi tasking tiles. Now the navigation and status bars are no longer visible and I can't do anything in the tablet because the error message pops up and it won't let me navigate. The error comes back every time I turn the tablet on. Someone please help. ?

A factory reset should sort that out.

I sorrowfully don't have USB debugging enabled and I can't do so, and I can't go through the factory reset screen on the tablet because it thinks I have a custom recovery.

Have you tried the default way of factory resetting? from powered off do the following : hold power and volume down, when logo appears release power, now also hold volume up and hold power again so you have all buttons pressed. You should be given the option to reset.
Good luck.

I've tried that. When i do that, under where it says confirmed in the upper left hand, it says "Secure booting error!" I'm pretty sure it has to do with the failed custom recovery. Thanks for trying to help. (But don't think I wouldn't welcome more help )

Try restoring your tab to stock via the 'Link to LG mobile support tool'. There is a little video here showing you how its done https://www.youtube.com/watch?v=ASllzBNc6hw

You will need to touch quickly. Atfer the force close message close, you have .5 second to touch the screen before it shows up again.
Happened to mine. In my case, factory reset did not help. Flash stock kdz will solve the problem.

Stuck on boot animation

Hi,
I unlocked via LG dev my phone yesterday, it worked fine, then installed TWRP and SuperSU. Then I restarted my phone and now I do net get into any bootloader anymore. I can use the Hardware Button combination to get into IMEI display screen, but nothing more. I always get the screen Bootloader unlocked then get into LG Logo animation and that's it.
Nothing more.
Sometimes I can start over and over again and I can get my phone recognized by adb, but it says "unauthorized" or "offline".
What can I do now?
Or is it bricked and cannot be used anymore?
edit: I got it in that state that I am not authorized with adb.
I put my pub key in /data/misc/adb/adb_keys on the SD Card, but it seems that its not working...
bye LG

Use the button combo to get into the factory reset screen. If twrp installed it will not reset but open twrp when going through the reset.

I can only use the combo to get into IMEI Display screen. Then I can get into boot animation screen. I cannot get into TWRP.
I can use lg flash tool 2014 and it will get until the screen on phone is at 0% copying, but it will not go further.
And I can get the phone to be regognized from adb, but it is unauthorized. What can I do that it will be authorized?? Is it possible to do that without being into andoir OS?

Do you have tried this exactly?
The only valid and always working and supported way on getting with a hardware key combo(!) into twrp is using the factory reset screen.
Any other key combo like vol up + power depends on the kernel of the ROM! So it may work or not. Factory reset will work always.
For this you have to ensure that you have the latest twrp version really installed(!) because if twrp sits in recovery it will ignore the factory reset command when going through it.
Power down and pull out the battery. Do not forget to remove any USB cable.
Press power down and hold it down. Put battery back while keeping vol down pressed. Press power button and keep now both buttons pressed. When you see the LG logo the first time just release the power button for 1 second ( do not release vol down ) and then press power again and keep both pressed until you see the factory reset screen.
Once you see that screen just go through the steps like you would do a factory reset. If twrp is installed you will just open twrp without wiping any data. Again it is mandatory to have twrp installed otherwise it would really reset your device.

Go into download mode and use LG up to flash a stock rom seems to be the next step you should try.

It is still the same problem. I can use the LG Flash tool, but it won't start the flash. It is stuck at 0% and the Flashing Tool says that the connection to server is failed.
I can still go into the reset menu, but it will do nothing.

Nokia 6.1 (TA-1054) stuck in boot loop

Hello.
I did a factory reset on the phone and it went normally but then at "set up as new" option, after booting up, started crashing and saying that setup has stopped working or something like that. I tried to access recovery menu to do a factory reset from there by pressing volume up and power buttons but instead of going to recovery menu, it's been stuck on "Powered by android" ever since. Can't even turn off the device and nothing seems to work. It's stuck.
PLEASE HELP!
