lmfao relax. Hold your volume button down, hold the end key down(the button you hang up the phone with) then push the power button.
When your phone boot you should see a gray screen that say serial, plug your device into the computer and serial should change into usb. Then run the rom and there u go

Doesn't that trigger Ramdump mode (well, I don't know what that means, actually)?
All the OP needs is to go to Bootloader Mode to flash a ROM via USB. Bootloader is easily accessed by: Turn off phone, then press/hold Volume Down + Power button.

thanks guys, ive been using android, and never a minmo device, thanks everyone!!

Yes that mode what ever its called

If you read the sticky posting on Task29, you would see it tells you that this is normal behavious for Task29, and it also tells you how to get out of it

Sortof. I just tried task29 for the first time a few days ago. I freaked out when I got in the same situation as him, but then read through the thread. There's the option of shutting the phone off, and pressing vol down + power key. I ended up doing vol down + power key + push reset with stylus at the startup screen. Simplest solution for me.

taking off the battery, istnt that simplest?
Amd here is the theme about this

In the very first posting of the Task29 thread, it says :
When phone boots to "Touch Pro 2" screen (or whatever your splash screen happens to be), I hold down the volume down button while hitting the reset button.

IMO, the smartest thing to do is when Task29 is near 100% (I think it pauses at around 96%), hold down the Volume Down button. That way, when the phone (tries to) reboots, it goes straight to Bootloader.

thanks all you have been more than helpful, ive been using this site for a while (for my android device) but just recently made an account. All of you keep on getting it done!!!

Hey, I have a Touch Pro2 and I tried the key combination above and it didn't work for me. I did get it to work however using the send key (green button) instead of the end key....
I.e, held volume down button, held send key and pressed power key once... ;-)

Phone MUST be off before doing the key combo...

unluckily, I can not hard reset by pressing volume down and power
DO U have another method?
thanks!

for hard reset on stock cwm : turn phone off. press vol up + vol down + power.

I had the same problem. I even got worse and the phone wouldn't even turn on. So what worked for me is this:
I put the phone in download mode (Vol Up + Vol Down and then plug the usb)
After that I open LG Mobile Support tool. http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
Wait for the program to detect the phone then go to Options-> Upgrade Recovery. Wait for the process to finish.
After it finished the phone loaded normally and everything was intact. All my files and apps were untouched.

[Q] F240L Stuck at bootscreen

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.

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.
