Hey all! Before I start, I'm on the lower end of experience (among those flashing an alternate OS onto a phone at least). I am on a Pixel 3xl. I have successfully unlocked the bootloader, and am now trying to flash GrapheneOS onto the phone. I have the unzipped contents of the downloaded file from grapheneos.org pasted into the unzipped SDK Platform Tools folder. When I connect my phone (using the phones usb-c cable) to my computer with the phone in the bootloader screen, I try to run flash-all (even as an admin) BUT the command prompt flashes up and disappears quickly, without doing anything on my phones bootloader screen. Here's what I've tried so far: -Running MalwareBytes to see if any sketchy stuff is preventing the cmd from running -Running Windows System File Check -Going into regedit, checking for malware that is pretty common (wasn't present on my computer) -I know I have the current version of Platform Tools or whatever FYI, other cmd files have been able to open as normal, just the flash all seems to do nothing. If I'm missing something obvious, please let me know; I am not a software developer of any kind, just a privacy-minded college student with a tiny bit of programming experience.
