I am also encountering the same issue and used the same setup as you did. The furthest I could go was copy all the kernel modules *.ko files into the aosp/device/google/redbull-kernel directory to solve the flashing issue. After a successful flash, the device will boot until the point where it shows the android logo and gets stuck there.
Would appreciate some guidance on this. Thanks!
