[Q] F240L Stuck at bootscreen - LG Optimus G Pro

my phone is stuck on bootscreen I tried flashing it following this method. Everything went successful but I can't go to recovery menu to reset the device cuz it's stuck on bootscreen. Anyone got any idea how to fix this?

I have found, on my phone anyway, that when you hold the volume down key and the power key it just sits there. I have to hold the buttons, let the power button go til I see the "LG" logo and hold the power button again. Then it gives me the factory reset screen. But you have to let go of the buttons as soon as you see this menu. Then you can hit power, hit power again, and it boots into recovery. Give that a try and see if it works.

ok so I hold down both power and volume down button then the lg logo showed up I released the power button and hold it again then the lg logo disappear and comes again and then it goes blank (um still holding both of the buttons) and the notification light keep on blinking. um really starting to get worried here I exchanged the phone with my galaxy s3 there is no way I cud return it now and I wudn't even try to re-flash it if it wasn't for the miui rom it had installed when I got it. I just want my phone to be at default 4.1.2 and now I'm clueless :crying:

however if I press and hold power and volume up button and when lg logo appear I keep pressing the volume up button rapidly this shows up:

i dont even know what it says its like in korean or something

That looks like the Korean download mode. When I use that method to get into recovery it's a bit tricky. I hold both buttons, nothing happens, while stil holding the volume down button, I let go of the power button just till I see the LG logo, then I hold the power button again til the small menu pops up. You have to let go of the buttons really quick when you see this menu because the power button and volume buttons are also the select button for this menu. Holding the buttons too long causes the menu to think you want to exit it....At least that's how it acts on my phone.

Remove battery, wait for 5 sec, attach battery again. press and hold power + volume down + home key, when you see reset option or recovery press power button to confirm and it will be fine.

Just try in the lg mobile support tool on top left and select update recovery the firmware will download and the phone will alobe get in the download mode and you don't have to do anything.

Download Mode

I am having no luck getting my device into download mode (I can't believe it).
If I hold volume up, menu, and power button, 'samsung' in white letters just keeps flashing slowly.
if i let go of holding them, then it brings me to an android recovery screen.
any advice please?
edit: solved ---- thought it was volume up i was supposed to hold, but is volume down

Yep... Vol Down + Home + Pwr for Download mode. BTW, it's the HOME (center) button... not the Menu key.

Device no longer boots or responds. Please help?

Booted into twrp.
Wiped cache system and dalvik.

Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

THIS TRIC'LL DO IT, BUDDY..... SUGGEST NEXT TIME YOUSTAY CLEAR OF THE HIDDEN MENU THOUGH!!! UNFORTUNATELY YOU'LL LOSE ALL OF YOUR DATA..NO JUMPING THIS.
1. Start your phone up by holding onto both the power button and the buttom volume key. When the logo pops up, let go for a second, and hold onto both buttons again. This should bring up the option to reset your phone. Agree to both prompts.
2. You should be on a new screen. It may warn you not to touch the screen because it is calibrating or testing it. You will have to press OK, and then give it a few seconds to do that bit.
3. The screen should have a list of options at this point (some of which say "+power) on them. If you want to use any of these options, you need to hold the power button, and then press that option on the screen. Press "normal boot (+power)" (don't forget to hold the power button at the same time). This should put your phone back to normal, and set it up again just like it came out of the box.
ENJOY YOUR PHONE BACK

Shut the phone down. then remove the battery and wait 20 seconds and reinsert it. Then try to get into recovery (look here for how to http://www.android.gs/enter-recovery-mode-lg-g3/) mode and see if the phone is recognised by the computer if you connect it. Then do a data factory reset in recovery.
Turn off your phone – you can press power button once for selecting “power off” or you can press and hold the power key for about 5 or 6 seconds.
Now, press and hold Power and Volume down buttons at the same time.
When the LG logo appears, release the keys.
Immediately press Power and Volume Down buttons again until the Hard Reset menu will be displayed.
Press Power button once and confirm the hard reset operation (this will not be necessarily if your LG G3 is running on a custom recovery image).
That’s it; now your LG G3 will boot into recovery mode.

How Do I Get In Recovery Mode?

I used "adb reboot recevery", it takes me to the laying android with "no command" but the old power button/volume nerve pinches don't seem to work to get to recovery.

This is the most finicky device I've had for getting into recovery.
You need to hold power and then press volume up and immediately release both of them....just keep trying, it's very picky

that is insane. After about 8 tries of doing like you said I got it. Finally flashing 8.1.
This took me a few tries.
When the Android logo is displayed hold down the Power key for a few moments.
While still pressing the Power button press and release the Volume Up key.
The following steps worked for me (taken from AndroidExplained):
Pixel 2 Fastboot Mode
Press and hold the power button for a few seconds
Tap the Power Off option when the Power Menu appears
Wait for the Pixel 2 or Pixel 2 XL to completely turn off
Then press and hold the Power button and the Volume Down button at the same time
Continue holding these two buttons down until you boot into Fastboot Mode

That only gets you into fastboot. From there you will need to select recovery, then you will arrive at the dead android screen, at which time you will need to hold the power button, then while holding the power button, tap vol. up to enter recovery.
Verified instructions
Here are the instructions I pulled from a Google forum:
1. Press & hold the Volume down button. While holding Volume down, press & hold the Power button until the device turns on. You'll see the word "Start" with an arrow around it.
2. Press the Volume down button until you highlight "Recovery mode."
3. Press the Power button to start recovery mode. You'll see an image of an Android robot with a red exclamation mark.
4. Press & hold the Power button. While holding Power, press the Volume up button once. Then release Power.

This works like a charm on the P2.
