[Google Pixel 4 XL Questions & Answers] ashtonv59:
Hey, I've been searching all through XDA and google to find someone with the same issue, but I can't find it. Plenty of experience flashing/rooting/etc. I've had a Pixel 4XL for a while now, never had an issue with custom roms. But lately I can't get it to take ANY flashes except official OTA sideloads or the online Android Flash Tool. Anytime I try to do a normal ./flash-all.sh it will flash normally UNTIL it hits the "booting into fastboot" (fastbootd) command. Then it will bring up the fastbootd screen and do absolutely nothing no matter how many hours you let it sit there while you resent its existence. Has anyone had experience with this? I'd really appreciate the help. Here is the full read out of my terminal when I flash (I've tried zsh and bash, i've made them executable with chmod +x, and have used them both with sudo and without):

bash-3.2$ sudo -s ./flash-all.sh
