P769 Safe Mode - LG Optimus L9 P760, P765, P768, P769

When rebooting, at the LG screen, press and hold volume down. This enters safe mode. Maybe certain exploits can be run that way, as minimal drivers/software is loaded? Just a shot in the dark.

Safe mode?

Did anyone know that our phone had a safe mode to them?
The only real safe mode is keeping it in the drawer and not touching it...
This is for the Galaxy S
If you run in to problems, you may want to try to boot the phone into Safe Mode so you can undo whatever was done to cause the problem.
1. Power the phone off.
2. Turn the phone back on while pressing and holding the Menu button.
3. Keep holding the Menu button until the Home screen loads. The lower-left corner should say Safe Mode.
Once you’ve removed the offending app, you’ll want to boot normally. To do so, pull the battery from the device, then replace it. The next time you start the phone, it should no longer be in Safe Mode.
FYI I have never had to do this.........
Hope that helps,

[Q] Safe Mode

Pretty much my phone wigged out started flashing between the lock screen and the keypad to unlock, so i took the battery out and it resolved the problem, but let to another. In which my phone is now stuck in safe mode and i can not get out of it for the life of me, ive done everything, called tech support and motorola but they told me to do everthing i already did, so they are sending me a replacement, but my question is there any other way to fix the problem besides, factory reset/data wipe, power down power on holding vol up and down etc.
What is safe mode
What is on the screen
all the normal screens it just has a tab in the lower left hand corner that says safe mode, doesnt allow you to use and apps, well downloaded apps, you can boot into safe mode by powering down and then powering on by holding down vol up and vol down and power button, and they told me to that to see if it would take it out of safe mode but it didnt happen

[GUIDE] [SAFE MODE] Enter safe mode on stock roms

This is an extremely simple guide for those who are not familiar with the opportunity of going into safe mode. Safe mode disables all your third party apps and prevents them from doing anything on your device. You can install and remove new apps, but you can't open any. This is also helpful to determine whether your battery genuinely is bad, or if it is an app or two who are the culprits.
To enter safe mode:
Press and hold the power button until the 'Phone options' menu pop up.
This gives you three main options - power off, restart or turn airplane mode on.
To enter safe mode you have to press and hold 'power off' for about 3 seconds. It will then ask you whether you want to boot into safe mode or not. (Tested on D802).
On some device models, you have to tap and hold 'reboot device' in order to get that option.
It works flawlessly and in order to turn it off, you just reboot your device. During safe mode, the phone can be used as usual, with the exception of 3rd party apps.
Hope this helps!
Sent from my LG-D802 using XDA Premium 4 mobile app
Or, from the phone turned off, press power until the LG logo appears, release power and press the volume up button + volume down until the phone boot. You'll boot in safe mode
(tested in d80220D)
Thanks for guide

thelightphone 2 - fastboot/safe mode

Just got my lp2 and it's a neat little minimal android device. The farthest I've gotten is not very far, but I can post here in case anyone's looking.
lp2, software v48 (48-release), firmware 4101.0.A.0070
fastboot:
you can enter fast boot by "hard rebooting": hold the lock and tool button simultaneously for 20-30 seconds, the phone should vibrate, then the screen will flash and it will show the "go light" screen, then turn off. Hold the power button again to turn it on, but hold the vol down button. It should stay on the "go light" screen. If it's plugged into your computer usb,
Code:
fastboot devices
should now list it. I also found it in usb info as having manufacturer "Google", while in the normal mode it has manufacturer "Android".
Code:
fastboot oem unlock
does not work.
To resume normal booting, press the lock button again.
safe mode:
if you reboot and hold down the ringer up + ringer down keys, it'll boot the phone into "safe mode". I'm not yet sure how safe mode is different from normal mode, other than there will be faint text at the bottom right of the screen saying "Safe mode". Rebooting will return it to the "normal" mode.
Has anyone else gotten any further? It's running a nonstandard base for android, so developer mode doesn't seem accessible from the menus. I'd like to at least get adb shell on this thing, but my endgoal is sideloading apps.

[HOWTO] Force a reboot in TWRP

So the dog tried to eat the phone, thus the bottom part of the screen is dead so there are no software buttons to use.
Now where the problem comes in.
You go into TWRP to see if you can make a more resent backup but you can't see enough due to the strips on the screen and since the software buttons are gone you're stuck and it will lock itself and you can't even swipe to unlock. Since newer phones don't allow the battery to be pulled you're stuck until you run it down which will take days.
TWRP and any other recoveries should reboot when the power button is held down IMHO but obviously they don't. Few things are more annoying than something electrical that you can't turn off.
I found that if you hold down the volume up and volume down buttons then press and hold the power button it will force a reboot.
Forced power off is holding power down and power button: https://www.verizon.com/support/knowledge-base-215164/
This is also provided as a popup instruction when you first boot the phone after setup. So, there is a way to force it off, just not with a single button as you might prefer.
You may have found another option with the reboot process.
I can confirm this procedure worked on my Redmi Note 4 (MTK) stuck in TWRP after I executed "/sbin/recovery" from adb shell, which killed the touchscreen and USB connectivity (??). The standard way (volume down + power) did not work, but this volume up + down + power worked, strangely enough.
