Latest OTA update stuck my phone in boot loop, please help me recover data

[AC Question]

Basically my phone is unrooted, completely stock etc. I tried to update it by pressing "update" on the notification. It worked for a while until it just said "Error!" with a little android lying on its back.
I got it to bootloader by pressing power+volume down, I tried to start it, but now it's just in a constant cycle of the google logo, "no command" with the android on its back, and then a message saying my device is corrupt and cannot be trusted.
I tried rebooting it by going to stock recovery and selecting "reboot now" but this didn't change anything. I wiped the cache and this didn't change anything either.

Please help me, I have photos on my phone that I need to save, I don't care if I lose everything else, is there any way that I can recover my pictures from this phone?

sorry I should have mentioned, my phone is a nexus 6 on android 6.0.1

Try Recovering files via adb (Post #22). No guarantee, but a phone in a bootloop doesn't normally have access to the data in a particular partition (other than the boot partition).

Most of these cases end in reflashing the ROM and losing your data, which is why EVERYTHING should ALWAYS be backed up.

How do I reflash the ROM?

I've given up on saving the data, I just want my phone to work now.
