Success at last!I'm trying to install TWRP on a new unlocked G7+ (updated to Android 10 patch level August 1, 2020)
Unfortunately, the fastboot boot twrp.img hangs on my linux host. fastboot devices reports my device is ready.
I've tried various images: twrp-3.3.1-lake-Q-v1.img, and twrp-3.4.0-0-lake.img with the same results.
Edit: I've tried using an oder machine with a USB 2 port and the boot command downloaded and restarted
the phone and looks like it tried to go to recovery. However, after a few seconds it returned to the bootloader.
I must be missing something. Any ideas?

(yes, I've cracked the glass)
I had to use the latest image twrp-3.5.0_9.-0-lake.img on a USB2 port.
