[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

Do you get to that factory reset screen?

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.

Cant boot into recovery mode

Hi,
I need some help.
So i rooted my D855 G3 using the avioch's 1 click method.
I then flashed the TWRP recovery image on the phone. Now every time i try to boot to recovery mode , my phone shows a "boot certification verify error" in the top left corner and then goes to a black screen with the LED flashing blue and red.
I am able to get back into my regular phone OS , so its not bricked. I have tried several methods of getting into recovery mode (apps, holding power + vol down, adb)
Please can someone help me with this , ive read soo many threads but cannot find a straight answer on how to get passed the error
Thanks

Same problem here my friend D855 stock rom 20i

Install TWRP Manager from the Play Store, and see if it recognizes that TWRP is installed. If not, you can use the same app to install the latest version 2.8.7.0

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.

[Q] P2a42 keeps stuck on first bootlogo

My dear P2a42 keeps stock on the first boot-logo :crying:
I've already tries to recover boot and system with TWRP 3.0.3 and TWRP 3.0.3-3. Also tried to wipe the whole phone and reinstall the ROM (the modded newest stock ROM), this also didn't work.
Strange problem IMHO... What's the best way to completely reset the phone to stock, flashing it with fastboot?? Or is there a possible other solution?
Thanks in advance :good:
Have a nice day y'all.

Actually in video it's fastboot method only i didn't read the article of yours properly.
Sent from my Lenovo P2 using Tapatalk

Lenovo p2a42 stuck on logo
Lenovo P2 is stuck in a boot loop.
I can't enter the recovery menu. If I press Volume up and power, it tries to start normally. If I press Volume Down and Up and Power, Phone enters "Bootmode is 'recovery'". After 14 seconds, it tries to restart in the normal startup.
If I press power + Volume Down, it enters a menu to swich between "Start", "Barcodes" and "Power Off". it shows dthe device parameters like serial number, storage, ram and the date of the installed software.
What can I do?

The only fix to get back into TWRP,
when the phone reboots, in the short moment of a blank screen you need to press Volume Up + Power.
The only catch is you have to press the Volume Up for a very short time.
It took me many attemps untill i got back into TWRP !!
Do not wipe anything or the phone boots again and you might get stuck in the same shizzle.
So install your favorite Rom & GApps and hopelly all works fine again.

Help!

So, I was on /e/ os, and I wanted to switch to lineageos, so I downloaded the zip, flashed TWRP (as recovery) went into it, flashed los, rebooted, got to boot screen, and right as it was about to go into setup, it turned off. I tried again, same thing, etc etc. I tried to go into fastboot and recovery, nothing. It's stuck at the Recovery mode... loading... then it has purple led at the top. it is the canadian h812 version.

Hi. I don't know exactly what the problem is and how to solve it. I would wait for an answer steadfasterX, or someone who knows the exact answer.
I would try to do this, but as I wrote above, I do not know if it will help or not:
Factory reset hardware key combo (https://forum.xda-developers.com/t/unlock-unofficial-g4-unlock-any-lg-g4-device-with-usu.3760451/)
As written above the regular key combo to get into the LG factory reset screen changes a bit:
power off device
disconnect any usb cable from the device
press volume UP + power button and KEEP THEM BOTH pressed until you see the LG logo the first time! THEN you have to immediately release the power button (ONLY that) and press and keep holding the power button directly again! Keep them pressed until you see the white LG factory reset screen
After that, I would try to go into the recovery, to format and restore or reflash.
Hope this helps. But it is better to wait for the answer of the knowledgeable. Good luck!

It worked... I hope the factory reset actually fixes it. (by it worked I mean I got into it)
Nope. Didn't work. It freezes up and says 'Secure booting error :1003' MODIFIED!' with a purpleish pinkish led.

Boot in fastboot and execute:
fastboot format userdata
(this will erase all internal data, pics, apps etc)
Then let it boot.
