I can confirm this works on my 2018 MacBook Pro with touchbar. Problem: Catalina beta 5 (File Vault enabled, did not allow booting from external drive) -> Recovery Mode -> Wiped main SSD -> tried using a Mojave USB to reinstall MacOS Mojave, but the system wouldn't boot. It kept reverting to the Internet Recovery. Option-Command-R and Shift-Option-Command-R (both on WiFi connectivity) presented error 1008F after 5-10 minutes.At this point, nothing worked. I didn't even care about downgrading... I just wanted to boot into SOMETHING.Solution: Shutdown, power on, immediately after powering on holding command-option-p-r until the Apple logo disappeared and reappeared. After it reappeared, I shut down the computer manually and repeated the entire process again (reset PRAM twice). Shutdown again. On the next restart, I held down option-command-R hoping the result would be different, and it was! No error 1008. Although AndyMck mentions that the time should show ~14 minutes, mine showed 6 minutes. It launched into recovery where I reinstalled MacOS (in this case, Catalina beta 5).*Whew*
