I've managed somehow to brick my phone. Booting stops at "Decription Unsuccessful" screen. Reset phone will not work. Cannot access recovery. ADB says phone unauthorised. Any assistance greatly appreciated.
Are you able to get into EDL-Mode with pressed Power and Volume Down-Button?
Boot into TWRP recovery. Select "wipe". There, you should find a button to change partition system. Change the data system partition type from f2fs to ext4. Your phone should now boot succesfully.

Shutdown phone, press and hold power and vol- button until you see the ftm screen. Then you can send reboot edl over adb.

Thanks for your suggestion but I cannot boot into TWRP. Data partition is already ext4.

Thanks. I was able to access FTM and send reboot over ADB. That action leads to black screen and no led.

You could now use the Axontool for instance and flashing "Fastboot, then (re)flashing roms, TWRP, et cetera. If you're able to connect via adb (to reboot the device), you should be able to follow the guides in this forum.

After attempting to use this tool:
http://forum.xda-developers.com/v20/development/lg-h918-t-mobile-one-click-recowvery-t3491969
It appears that I do not have any recovery installed or it appears I don't have a bootable recovery. Previously I got the custom TWRP recovery to work but the installer went ahead before I was able to wipe data. Now I cannot even boot into stock recovery. even the command "adb reboot recovery" just makes the phone start up normally. Volume down + Power makes the phone start normally as well.
attempting to run the tool again will cause it to deny flashing the custom IMG file as it tells me my recovery is already modified and won't continue unless I turn off verification (highly ill-advised) It refuses to flash TWRP.
At least I have a working phone and not a boot looping brick but is there a way to get stock recovery back just so I can try again? I have been told I need to re-lock my bootloader and hopefully that will restore everything back to the way it was so I can start again.
Any help is greatly appreciated!

If it is the stock recovery it will only format your system to how it is out of the box.
If it goes into TWRP then you'll know.

That doesn't work for me on my Freedom Mobile H915 with a locked bootloader. I only ask how to without ADB because I want to help someone else that bricked their device upgrading the firmware to factory reset it and/or wiping cache hoping it'll help.
I was flashing the MM zip file that was provided with TWRP but when the phone restarted it just got stuck on the logo (not the lg one). Can anyone help me?

I made a mistake by flashing the SuperSU zip without booting into the system first. Can you tell me how to boot into recovery with the hardware buttons ?
Turn off your device then hold down power off + volume down button when you see lg logo release the power button for a second while keeping the volume down button pressed then press and hold down power button again with the volume down pressed. Your phone should boot up into factory reset menu click yes to factory reset. Don't worry click yes to factory reset. It will boot into twrp.
NOTE:- It will only work if you have latest twrp build installed, won't work, if you have first build installed.

If you still have the first build, you can still enter the recovery by adb with "adb reboot recovery" while the factory reset scrip of the twrp runs. It won't be immediate, you'll probably lose your data but it will work

You need to use at least SuperSU 2.79, previous versions won't boot and will get stuck al LG logo.:good:
[Happened to me >.<' ]
The problem is I can't start my phone at all. Can't get adb because I can't boot up the system. When I go to recovery TWRP just does something and reboots to the system where it gets stuck again.

That "something" that twrp does is probably the factory reset scrip, so you have to keep the phone plug and adb running so while it's doing "that something" use "adb reboot recovery" command

Only option left is Download Mode and flash .kdz again.
Take out batery, plug the phone and put the battery on while pressing vol+
By the way, which SuperSu version did you use?

I really don't know what happened then. I flashed SuperSU and MM altogether several times (Trying to fix another problem) and I never had a problem.
But well, as long as you have Download Mode you can always start from scratch

Remember, without battery plug it to the computer, press Vol+ and then put the battery. It'll show you a message telling you to keep de Vol+ until the "Download Mode" screen appears

Ok so I got everything back to normal thanks to you guys. But I have a question. I found that there are 2 aboot.bin files in the system. One is in dev/block/bootdevice and one is in dev/block/platform. So do I run the command twice for both or do I do just one ?

These are the same. Just do
Code:
dd if=/sdcard/aboot_v10f.bin of=/dev/block/mmcblk0p5
assuming aboot_v10f.bin (the patched aboot) is on the root of internal storage.
Thank you very much to everyone that helped. Everything worked perfectly. Had some problems with the official TWRP app so I used Flashify to flash the recovery. For now I am going to use the v10f rom until there is a custom one ( hope we get LineageOS soon ).

Dont reboot the device after flashing recovery in ADB. Boot straight to recovery.

but can u tell me how to reboot straight to recovery while finish flash recovery in fastboot mode, i can't find way do this.
I have unlock the bootloader so each time i boot up the phone, first there is a lg logo displaying for about 2 second and then a warning msg will appear on the screen. this warning message will display on the screen for about ten second and then a lg logo appear again then boot the android system. i don't know how to interrupt the normal boot process and get into recovery manual.
when i use adb to reboot to recovery, lg recovery will appear after the warning message screen off. i turnoff the phone and press power+down button together to try to get into recovery manually, but after the lg logo appear the second time, there is no way to start recovery. the phone will boot to android directly.
ok i find the way to get into twrp now by vidoe in youtube.

Also having this problem, however when I hold the POWER+VOLUME DOWN buttons to try to boot into recovery after shutdown/battery removal - the system STILL loads.
I get the warning saying the bootloader is unlocked though. After that the phone just starts up as normal, even though I'm holding the buttons

here is the step i find finally
1. re-boot into fastboot mode
2. flash twrp use fastboot command.
3. power-off the phone
4. power-on with power and volume down button holding
5. while lg log appears, release power button immediately for 1 second and then hold again
6. when recovery selection screen appears, select 'yes' both two times.
now phone boot to twrp recovery.
REMEMBER: WHEN YOU BOOT INTO LG'S SYSTEM AGAIN, YOU WILL LOST TWRP. IF U WANT TO USE TWRP AGAIN, U MUST RE-FLASH TWRP AND REPEAT THE STEPS ABOVE. THIS WILL LOST ALL DATA(PHONE WILL GET FACTORY RECOVERED)!!
I hope this can help you, good luck.

You need to delete the file recovery-from-boot.p in /system
Each time you boot, that file gets executed and restores the stock recovery from recoverybak. Alternatively, you can flash TWRP to both recovery and recoverybak.

Hey all! Got a quick question for ya. So the key combo to enter fastboot mode is volume up and power right? It won't work for me and I'm not sure why. When I press volume down, recovery mode works just fine, but trying volume up boots OxygenOS normally. Using advanced reboot from developer options can put my device into fastboot mode, but key combo won't work. Suggestions? Thanks guys!

adb reboot bootloader
Edit: I just tested it out on my TMobile variant.
Power + vol down (this is the typical button combo)
It then asks for my pin. Then asks for language. Then its the recovery mode. Asks to wipe, clear cache, or boot into fastboot.

That's exactly how mine works! Volume down takes me into recovery, which has an option to reboot to fastboot mode, and that WORKS! But holding volume UP for fastboot mode boots the device normally. Weird. Maybe that's just how these phones work? Recovery first, THEN fastboot? Idk, I'm puzzled here.
EDIT: Might be worth mentioning I bought mine from OnePlus directly. The 256GB storage model.

Found the answer:
To boot directly into fastboot mode, it's vol+ AND vol- and the power button.
All three buttons.

Install twrp through magisk
try this, root without twrp, it worked for me
TWRP dont support Android 10
