If a non-functional bootloader were flashed to the SPI flash, then that would be the 1st choice for the RK3399 to boot from, right? So even with a working SD card and eMMC disabled, it would try to boot from SPI and fail (assuming SPI has a bad bootloader).

If a serial console cable is used, then it should be possible to see if pbp is attempting to boot at all and from what it is booting. Then you narrow down which of the two most likely problems you have, a) bad bootloader, b) bad battery.
