[Q] Can't boot to recovery

I have a F400K G3 (Korean Olleh). It's rooted and bumped. I flashed the bumped TWRP image via Flashify and rebooted recovery via Flashify. It works. But when I try boot to recovery from a complete shutdown. It just boots into safe mode. I did exactly what was stated in the Bump thread (Power+V. Down, when logo appears, release then press again quickly) and also tried substituting V. Down button with V. Up, but it still wont boot to recovery. It just keeps going into safe mode. The video provided in the thread was using an AT&T model so maybe it differs from every variant. I want to know if I'm doing something wrong or the instructions are wrong.
Thank you.

You tried without releasing? Just keep holding buttons

I have tried it as well without releasing. Does the same thing. And it never shows the reset screen. It just goes directly to the boot animation. Rebooting from Flashify also doesn't show the reset screen but it does get to TWRP. But I need to boot it from complete shutdown because I'm gonna test a Flashable zip ROM without root so rebooting using Flashify would be impossible.

Bump.
Seriously. Anyone?

I am subscribing because I have the exact same problem. I have tried every key combination I could find for the G2 and G3 but no luck...

This is exactly the kind of problems you get when using stuff like Flashify. The holding of the buttons etc you mentioned should work. Are you sure you aren't connected using a micro usb?

No, I am not connected to USB. If I reflash the recovery using ADB will it work? But I do have some worries because I'm using KitKat bootloader on a Lollipop Stock-based ROM (here) and I think I may get some errors.
It's not very important right now because I have root now and can reboot to recovery using Flashify.

I think all korean models cant enter recovery via hardware keys, mine is F400L and have the same problem.

Turn off the phone completely. Press and hold Power and Volume Down. When the LG logo appears, release. After a split second, press volume down and volume up. White screen asking you to reset will appear. Press Yes two times using Volume buttons.

UP!!!
Any remedies? I justed from stock to cm12 LG g3 F400L..
Cant go to recovery mode. Cant flash anything..

Same prob,always going to safemode.f400k rooted,cloudy2.5

i've Lg g3 F4ooL and using Resrruction remic 5.5.5
I stuck in a Bootloop and my device is also not booting into Recovery or safe Mode.
Lg flash Tool is also not Connecting to my device in Downloadmode.
I think There is NO solution At ALl

Has anyone solved this issue?

to get in recovery on F460s, worked on mine, Press Vol-up + Power, as the logo appears release the keys and press Vol-up + Vol-down, you will boot into recovery.

I have the same issue, cant go into recovery using hard buttons on F400K. Any one able to succeed in this?

Same issue on LG G3 F460S, no combination of power + volume buttons + releasing them and pressing again when LG logo appears works. The device go straight into booting system and gets stuck. Is there any other method - maybe short-circuit some pins on the motherboard, to boot into recovery or do a system reset? Please...

OK, turns out that the combination is different for Korean models of G3, as misbah711 wrote, volume UP + power, when logo appears, release and press both volume UP + volume DOWN. If that does not work, try again, but release only the POWER button and press immediately volume DOWN (while volume UP was held all the time). Also, I first tried it without the back cover, as I have to remove battery to turn it off, did not work. Then with the cover it did, not sure if it's an important detail or not.
However it's not the end of the story for me. An image with Korean text appears, and nothing. No combination of power and volume buttons pressing does anything. I'm attaching the image. Also tried a web service to do Korean OCR and then used Google Translate - does not make any sense. Could anyone advise how to proceed and do a factory reset on this device? It won't boot into the system (gets stuck), no adb or any other communication with it.
Edit:
Turns out that when the Korean text appears and I connect USB cable to my PC, adb works correctly. Typed:
adb reboot recovery
The phone rebooted into recovery and now I'm doing a factory reset on it. Looks like all will be fine.

i have d851 on stock kitkat. I flashed TWRP and Philz but no way i can get into recovery mode. it always goes to fastboot mode no matter how I reboot into recovery. Now i am looking for stock recovery image. or a way to fix the twrp/philz. ROM boots just fine.

[Q] Secure boot error

hi all! I've certainly royally screwed myself over this time around.
I installed sling v3.2 and restored my apps, after restoration I tried to unlock bootloader with freegee (since it was pre-rooted) and freegee showed it was already unlocked, so I tried to flash a custom kernel and viola! this happened!
Problem is, my power button is close to broken and no amount of pressing down will turn the device off. is there anyway I can turn it off or save my Optimus G? thanks in advance!

UPDATE:
I've tried to get into download mode but to no avail (tried pressing volume up + down while ramming the power button on my PC desk). I tried Vol Down + Power and I got into factory reset mode, so i pressed vol down because I didn't want that.
It restarted to LG screen which showed that dreaded secure boot error message. This time around I tried Volume Up + power button and it restarted but with the message "something unLock!! restart boot!!" something like that, didn't really see what it was, it flashed too quickly for me to see what it said. Anyways it then rebooted into CWM and now I've cleared cache/dalvik/system/data and re-installed Sling v3.2!!
Hopefully this will work out so I'll update this when it finally boots back to life! (hopefully!)
BTW, my device is an LG F180K the Korean Variant, it's color Maroon with an Olleh logo at the back, just in case anyone was wondering.

I had a similar issue but was able to get into recovery mode and restore a backup.
Can you get to recovery like this
Power Down the LG G4
When Off, Press and Hold the Volume Down and Power Buttons at the Same Time
Continue Holding These Two Buttons Until You See the LG Logo
When You See the LG Logo, Let Go of the Volume Down and Power Buttons for 1 Second
After 1 Second has Passed, Immediately Start Holding the Power and Volume Down Buttons Again
Continue Holding These Two Buttons Until You Boot Up into the LG G4 Recovery Mode

i told you nothing work i cant go in recovery mode with this option . and hard reset doesnt work too ... im blocked

Hi I'm sorry if you've already said you can't get into recovery mode or anything but when i bricked my g4 i used the lg flash tool to flash h815 10c stock and then instead of flashing the latest twrp (the blue themed one) i flashed the one before it which is 2.8.6.1 and it worked perfectly so if you manage to get into recovery or fastboot then try and flash that version of twrp instead , good luck buddy...

How did you "brick" (it's not) it? Kill switch is an anti theft feature, usually triggered remotely by the user.

This button combo you posted is wrong any way...you only release power for 1 sec and continue holding vol down and the re press power

I cut and pasted those instructions from another site. They held me back from fixing my phone for hours until I discovered the method you have mentioned. I haven't seen any site that tells us to do it like you said, I just was trying different ways and then hey presto!! it worked.

LG G4 bootloop. Can't go into recovery/safe mode and pc isn't recognising phone usb

My LG G4 goes to the 'LG Life's Good" loading screen and just stays there. The light swirls around the LG logo repeatedly and the devices sometimes vibrates once or twice when I press the back buttons a lot.
I have tried going into recovery mode and safe mode and they don't work. Also, my PC doesn't connect via USB to the phone while it is in this state.
Any ideas?

so how did this happen? did you try to root, flash anything? Is the phone on stock firmware? lp, or mm? give us something more
How did you try to enter recovery? Try to hold power+volume down, when lg logo appears release power but NOT volume down. Wait 1 sec then press power again (while still holding volume down) this is the correct way to enter the recovery
