If you are getting internal system problem on first boot then please download and flash linked vendor image via fastboot (fastboot flash vendor vendor.img --slot=all) or recovery on partitions A & B.

Well I got the internal system error on boot and I have July flashed to both slots so maybe this is based on August or something else is going on.
