My friend has LG G7 ThinQ G710AWM 20d, Android 9, and I'm unable to enter into fastboot or recovery mode because I plan to wipe and install a custom ROM without all the bloatware and spyware. Tried ADB, button combos, etc. No luck. I've successfully rooted and modded other phones but I am stuck with this varient, please help!
UPDATE:
I think I need to cross flash to Android 8 Oreo, I am stuck at which firmware to flash from the LG site, there's a bunch of them listed for the model G710AWM all having different versions.

I decided to downgrade from Android 7.0/Nougat back to Marshmallow, so I flashed the H850 .kdz file using LG UP to downgrade. Unfortunately it failed and now my phone only boots to download mode.
I have tried to boot normally and into recovery mode, but I am taken into download mode each time. Any help?
Edit: Fixed by plugging into LG Bridge. Bridge detected that it was running Marshmallow and updated it to Nougat, correctly restoring the software.
to downgrade follow

I have a LG G5 h850, and I am trying to install a custom ROM, but I can not access the recovery mode, I try physically through the buttons, and through the ADB appears the message "no command"
Dear XDA community
Recently I had bricked my LG G5 on LineageOS (red boot flag - system integrity check problem found or something like that) and after that I reflashed the firmware with LGUP and various kdz files. Everytime it works good but I get the common error on boot (can not match cust for NTCODE=[,]) but still it is not an issue. Yesterday I found out that i can not longer access recovery even after flashing TWRP from fastboot, it seems like the factory reset prompt just vanished. I tried many combinations for accesing the prompt but it doesn't show up and the device boots up normally (LG logo -> orange flag (bootloader unlocked) -> LG logo)
I hope that someone will find a way to solve this issue.
Also i noticed that LGUP does only a dirty flash and everytime it leaves some system apps from "clean europe kdz... with Orange Jeux app"
So tracfone doesn't allow me to unlock the bootloader of my motorola e (xt830c). I know its kinda stupid, but I tried flashing a stock rom for the moto e but for the standard U.S. version to see what would happen. It didn't work, but I was still able to flash the standard Tracfone firmware back. However, I didn't learn my lesson and I decided to try a different version. I didn't work and neither does flashing the tracefone firmware. It only boots the logo, then the fastboot screen and it says:
version downgraded for boot
failed to validate boot image
Fastboot Reason: Fall-through from normal boot mode
USB connected
Is there anything I can do to unbrick it?
Thanks for any help.
If your LG G6 G600L bootloop when trying to use and can only be saved by charging the phone.if cant use lgup to reflash stock firmware.use lg bridge and if the problem still there after flashing using lg bridge.do what i do.try to enable usb debug.enter adb and check the devices using adb devices.if its there proceed to enter this code.adb reboot recovery. and on your phone it will say erasing and will boot and the phone is fixed.all data will be lose thought
