But this boots to normal boot with completely purple not working screen.
And I couldn't figure out that it is normal install is broken but not recovery boot.
To more confusion, before accassing lineage recovery or TWRP loads common LG recovery and offers delete all user data.
This creates impression TWRP or lineage recovery is not installed and is broken.
Now everything works.
I used key combination VolumeDown Power release power on LG Logo and hold Power again. Chose erase user data / factory reset and this let me boot to custom recovery mode and flesh rom with sideload command.

Can't boot into recovery using vol down+power but can boot normally

Hi,
I can't boot into recovery using vol down+power but I can boot normally into OS and from there I can boot into recovery through ADB or third party apps.
I was trying to update my OP2 with new OxygenOS 3.0.2. As my device was rooted so I had to do it manually using TWRP. Till now I was able to boot into recovery by vol down+power.
Before flashing I wiped everything(dalvik+cache+system+data), rebooted into recovery and flashed the OOS3.0.2 full ROM. At this point the installation was successfull but I was not able to boot the OS, it was stuck on the loading screen. After several attempts to boot OS, I finally tried to boot into recovery to flash again, but I was unable to. When I press vol down+power for few sec, the phone switches off with a vibration.
Later I found out that I was supposed to use a modified TWRP. So I flashed the modified TWRP via fastboot and flashed the OOS3.0.2 full ROM again, Now I can boot into OS normally but still I cannot boot into recovery by vol down+power. But the interesting thing is that I can boot into recovery through ADB or third party apps.
I tried flashing the TWRP recovery again with no luck. I thought this could be a problem with boot.img which is contained in ROM itself so I also flashed the ROM again with no luck. Also I am absolutely sure that this is not a hardware issue with by volume buttons as I can use them properly when I boot into OS.
A quick thought, is it possible that the boot.img of the ROM itself is broken? Seems unlikely as I am not seeing anyone else having this issue. But if it is, is it ok to flash the boot.img from OOS2.x version ROM, will that be compatible? Just wanted to be sure before doing this.
Any other thoughts are welcome.
Are you used this command for flashing twrp??
fastboot flash recovery recovery.img
You should add "flash", otherwise it won't install twrp in your mobile
yes I used that command only

After flash recovery use this command it will help to boot in twrp "fastboot boot recovery.img " without quotes
yes I know that, thats how I booted into recovery from fastboot for flashing the ROM. But I should be able to boot into recovery by vol down+power. That is why I posted this question.
Will you please send me screenshot of cmd?? after flash recover

You have to install a custom rom or root to make twrp permanent, if you don't do that it will install always after the first boot the stock recovery.

You need to reflash twrp with the bootloader like the first time.

When you have flashed twrp, you do the buton combination to enter twrp, if you fail to enter twrp a the phone boots into system the stock recovery will be reflashed so you have to reflash twrp.
Try making these:
When you are in the bootloader after flashing twrp press button down+ power button. When the screen turns off quickly stop pressing power button and quickly press again until the lg logo appear.
When the lg logo appear stop pressing power button, quickly press again and stop pressing the power button and press again quickly until you see twrp logo.
These method works for me for booting twrp easily
The stock recovery appears but you have to select the factory reset option and it will boot into TWRP

Unfortunately still not succeeded after trying all the solutions i've found here
Hey, i have the same Problem, my TWRP broke, i can't boot into recovery and my Device ist not listed in fastboot mode. Can someone help me out?
I get the ring in windows when i plugin but its not recognizing.. Can someone pls help me out?
Okay, I'm going to try to explain it, and see if I can succeed where others have not.
You install TWRP by booting to bootloader and using fastboot to push a new recovery:
Code:
fastboot flash recovery twrp.img
It seems like you accomplished that successfully. The next step is to immediately boot to recovery; do not boot the phone to system first. You will get the factory prompts for wiping data, but it will not actually wipe your data this time. Instead it will boot to TWRP.
Now, while you are in TWRP, you need to either root (flash Magisk) or install a custom ROM. If you do not, your next boot to system will remove TWRP and restore the stock recovery. If that happens, then the data-wiping prompts the next time you boot to recovery are real and the phone will wipe. So you MUST - must must must - root or install a custom ROM while you have TWRP up, in order for TWRP to persist.
If you have already experienced this problem, you need to start over at the beginning; flash TWRP again, and then follow the rest of these directions.
Maybe this will help clear up the problem for you guys.

I only manage to see the TWRP welcome screen and the the phone automatically reboots to system

WTF is going on?
I have repeated the process many many times and always the same. What i am missing here?!?!?

Got the same problem. I unlocked Bootloader, checked if unlocked (yes). After flashing TWRP i see the TeamWin Screen and phone boot again. There is no TeamWin Menu.
A try with an older TWRP-Version and flashing via fastboot with another PC does not work too.
Anybody an idea?

With 3.2.1.0, 3.2.2.0 and 3.2.3.0 it only briefly shows the TWRP screen and then boots into system anyway.
With 3.1.1.0 the key combination to boot into TWRP as with the other versions above simply doesn't work, again it directly boots into system without even showing the TWRP screen.
I'm stuck with a resetted phone because of this bull****, because some instructions said "oh, the reset dialog will not really reset your data..." - yeah thanks for nothing, buddy.
So what now?
EDIT: I got it working using TWRP 3.1.1.0, but the same version from the OFFICIAL site didn't work, as I described above.
The only 3.1.1.0 TWRP that works with my phone is the one from this Link: http://downloads.codefi.re/rashed/g6/
(which is linked ... somewhere here in the Forum, don't remember which thread)

Not booting into TWRP

Hey everyone,
I decided to root my lg g6 and got a fickle. After unlocking the device and flashing TWRP I tried to boot into it (''adb reboot recovery'' command) and it deleted all data and then twrp shows on screen for a split second and almost instantly boots normally into android so I set it up while still being unable to access twrp and any of it's functions. Does anyone have any idea what could be the problem?
P.S. Of it helps: before that i had a problem that every time I tried to use the ''adb reboot recovery'' command the console said ''no devices/emulators found''. After a couple tries I wanted to check whether the phone was connected just to make sure (''adb devices'') and after that it worked and I ran into the problem above.
Thanks for all the answers
When you first unlock BL and flash recovery you have to manually enter recovery mode.
Hold power and vol down till it turns off. Hold same buttons again until you see lg logo. Release power and press and hold again.
Then ask you to wipe etc hit yes both times and it will boot to twrp.
I tried that but it still doesn't go into twrp. After confirming that wipe stuff it just boots into android (without wiping)

You have to flash TWRP recovery and when it complete then use the button combo to boot into twrp, otherwise it will boot and restore the recovery.
flash twrp
button combo to twrp
done
Yes I've done that but the problem still exist.
btw thanks for the help
Maybe try fastboot flash recovery recovery.img
Try the all-in-one tool on this forum
By the way, I am running into the same issue.. I have a LG G6 US997,.. I have tried installing TWRP unofficial ones so many times and every time i manually try to access the recovery.. the phone simply wipes all my data to default
Hello,
I have the same problem. Did anyone figure out how to solve it? I'd highly appreciate any help.
If I try to boot into recovery, it asks me to factory reset, i hit yes twice and then the phone just goes on to boot normally. The data is not wiped but I can't get into TWRP.
If I enter "fastboot reboot recovery" after flashing TWRP it returns "fastboot: usage: unknown reboot target recovery"

OP5 Needs Help: Wi-Fi Broken And Unable To Boot Into Fastboot Or Recovery Mode

Hey all, I recently flashed the xXx_NoLimits_3.5_magisk_rom
magisk module and the blu_spark_r136-custom_treble_op5-op5t_d8ba1bb.zip and my Wi-Fi function broke.
I did a backup on TWRP previously but then found out I can't boot into either recovery (not even stock recovery) or fastboot mode. I then uninstalled the xxx magisk module but still can't boot into recovery/fastboot mode. Thus, I suspect the problem is with the custom kernel. Problem is, even if I want to flash a new kernel, I can't use fastboot to install twrp boot.img
I did a factory reset but the phone just did a regular reboot with no data loss at all. Is there something I can do to get fastboot working again?

If you power down the device and power up with pressed power h volume up button what happens? Did you see the menu to select either fastboot or recovery to boot in?
Which stock oos rom do you have?

Hi, adb recovery boot, quick reboot pro app, and OP5 advanced reboot buttons didn't work, but booting into recovery manually (holding vol down + power buttons) worked, so you are right about the method. Thanks for your reply.
If you are running OOS, you flashed the wrong kernel version. Note the difference below:
blu_spark_r136-oos-treble_op5-op5t_4aea761.zip
blu_spark_r136-custom_treble_op5-op5t_d8ba1bb.zip

G4 Plus stuck on twrp recorvery unless booted through recovery mode (power+volume dn)

I recently installed twrp instructions and installed a custom ROM. Even since then the device boots normally into twrp recovery only. to boot into the rom, I have to boot through recovery, press power + volume dn and then it boots to the regular ROM. Should I start over on this or is there a way to change that preference so the device boots normally into the OS instead of twrp.
Sorry if this has been answered somewhere else already. I looked.

I am facing same issue. I don't have twrp or custom rom but stock recovery and stock rom. Everytime I boot or restart my phone it goes to recovery mode!! I couldn't find solution yet and its very annoying.
Try following the steps in this thread: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325 Of course, ensure you have backups before erasing anything.
