After you have installed TWRP via adb you must boot (or stay there) into revocery and falsh the twrp-xxxx.img as "revocery" (buton down right to change from image to recovery).

Try this:
adb reboot bootloader
fastboot.exe flash recovery twrp-xxxx.img
fastboot.exe boot twrp-xxxx.img (same filename as above)
Then flash the same twrp-xxx.img file via "install"
After this you can direct boot into revocery with apps like quickboot, or via Vol-Down, Power-On, or direkt via reboot meneu if you use G4 Tweak Box.
If you are on 6.0 the recovery will never boot up. But don't worry, all you need to do is just download kernel package like SimpleGX, from this package copy the boot.img, then flash it via fastboot. After that let the phone boot up, reboot it to bootloader again and flash twrp.img. If you did it properly the twrp will boot up. REMEMBER to flash full kernel package otherwise you can have problems with your device.

Never flash recovery for H811 on H815, there is reason why they are different.. You could have bricked your device. Yes flashing this boot.img is completely safe as long as you flash full package later, otherwise you might have problems with software. I've done so many times without any issue, anyway it's not a softbrick, you always reflash the firmware however be aware of that if you do it wrong and get your phone bricked without access to custom recovery there is no way to recovery your data. My G4 is dead but this is caused by the well know bootloop issue (hardware fail).

Thanks for the quick answer... I got a replacement and it ships with v20d twrp for h811 was the only solution to get root... Now i have seen your post... Will try it later... I hope it works
Do you know the reason why we have to flash the kernel? Some poeple can flash twrp without...
edit: i have flashed the kernel but flashing twrp dont want to flash...
the result of fastboot is positive but if i want to boot in recovery the screen stays black and then the phone boots up normal to os...
woult it help to kdz the phone to lolipop?

Install Twrp Manager from the Play Store and then install Twrp 2.8.7.0 from it.
It's working fine on my H815 v20d

I have no idea how did you manage to install TWRP recovery on official 6.0 firmware since TWRP manager requires root and to root android 6.0 you have to have modified boot image...

As I mentioned above in android 6.0 google have modified it as the stock kernel does not allow to use unsigned stuff even though your bootloader is unlocked. So only way to root/install recovery on android 6.0 smartphones is to flash modified boot.img that allows to load unsigned things. If you flash recovery without changing stock kernel you'll not brick your device but the recovery will never open, but flashing superSU might brick your device, Autoprimes flashable zips include modified boot.img I suppose.

i have no more idea what to do... i have flashed the kernel... and then recovery but when i want to enter recovery nothing happens it doesnt load. after some seconds the phone boots up normal.
before that i have tried twrp manager but the app crashes every time i want to select the recovery to install.
flashify is same as flashing over fastboot.
what is the difference between the 2 versions of twrp? h811 got another kernel than h815 but why can i load this one but the right for h815 not?

I have no idea honestly, try to reflash the firmware. Recovery doesn't load only if you don't flash boot.img properly.

how do u unlock the bootloader on a LG G4 H811 ver 20i
It happened with me twice on Lg F220 & LG G2Ls980, stock lollipop firmware and TWRP Recovery was installed on both devices, i just rebooted the device to recovery mode to see which version is installed and explorer the different setting(i didn't activated anything) and reboot back to the system, now every time the device starts, the brightness level go to 100% and screen off time to 2mins. this happened on both of the devices, can some tell me what caused that problem.
Now i have bought an LS980 for myself, i have successfully rooted it and now its time to install a recovery, personally i love 4ext recovery but unfortunately it is not available for this device, i have only option to install TWRP, but now am afraid that if i installed it same problem will occur to me :crying:
""My device has Stock LS980ZVA installed""
Insert sim card or use custom rom. Its not a recovery deal

Never experienced that, after installing a version of TWRP, upgrade to Blastagators TWRP 3.0.2.1 bumped & signed. I don't have the link handy, but searching should find it for you. But i agree, i have never had this happen on any version of TWRP recovery -i thinks it's un-related.

Is there any difference between normal TWRP & Blastagators TWRP ??
i have a Lg g3 (F400S). Currently i am running on cloudy g3. i wanted to update to FULMICS 5.0 ROM. while following the instructions for the rom it was strongly suggested to update your TWRP. previously i had TWRP ver 2.8.2.0. so as per the rom instructions i downloaded TWRP ver 3.0.2.0 for f400 and booted into recovery to install updated recovery image. there i could not see the image button (The option in install menu which allows you to install .img files) in the install menu of TWRP so i downloaded the TWRP app from play store and after selecting the correct TWRP recovery image i installed it from the TWRP app. the app gave me a success message.
but alas now i cannot boot into recovery mode any more. it gives me
Boot Certification verify
----------------------------------------
secure boot error!
Cause : boot certification verify
----------------------------------------
fortunately i can still use my phone and my cloudy g3 rom is running without a hitch. i can also enter download mode successfully. the only problem i am facing is when i enter my recovery mode
P.S i made a backup of all my partitions from TWRP before proceeding with any thing and i still have that backup.
if any of you can help me correct my recovery.

Anybody Plz can i somehow use my backup to restore my recovery through TWRP app

Or use adb......

Also make sure your SD card isn't formatted.. That worked for me but not sure if our issues were exactly the same
I have LG G3 F460S but when I go to recovery mode there is korean language so i can't understand.What should i do.?

I installed some LG Drivers from a root article and now the phone is recognized. I can update to V20G and test it again, hope it works!
Hello!
I was running CM14.1 on my LG G4 and a few days ago I decided to install a new update but from within the phone itself. Sadly, it just rebooted to the recovery and didn't install anything. And from there, it always rebooted into the recovery no matter what I did. I also did a full wipe and installed CM14.1 clean but it still rebooted to the recovery and didn't want to go past that. I made a Reddid thread - https://www.reddit.com/r/cyanogenmod/comments/5gcap3/g4_h815_cm_141_help_i_cant_boot_outside_of/.
So I got help with that - I got into Download Mode and flashed the stock software via LGUP. Sadly, after I did this, I can no longer install a custom recovery. The phone is not rooted and LGUP and LG Bridge don't recognize the device anymore and the phone says there isn't a new update available but it's on the 5.1 stock ROM.
Whenever I flash the TWRP image via fastboot and I reboot into recovery, it doesn't boot into TWRP but it boots into some kind of other fastboot mode. And I've tried to issue `fastboot boot twrp-x-x-x.img` but it fails to do so and shows `FAILED (remote: dtb not found)`.
Is there a way to fix this so I can flash CM again?
Thanks in advance!

The bootloop to recovery is a known issue of one the December nightlies of CM 14. Head over to the CM thread and search for bootloop and twrp. They provided a solution to solve this too.
Besides that: which twrp version do you tried to fastboot? H811 or h815? Taken from the official download site?

twrp-3.0.2-1-h815.img, H815 as the title says and from the official website as I've always done. As for the thread - I don't have TWRP and I can't even flash it as I've written in my post. That's what I'm struggling with.
Edit:

Hi
I've tried 3 different twrp images, all supposedly bumped (take this one for example), but when I try to boot to recovery with any of them I still get the boot certification verify error and can't get into recovery
running rooted 5.0 stock wiped, installed by instructions in linked threads
Thanks
update: used autorec, can now access recovery... but it's twrp 2.8.6... can I install fulmics on this version, or how do I update it?
update 2: TIL that you can update twrp from inside twrp and it still works, but that still leaves me confused with the above problems
