the wiki describes a method where "jump drive" can make the device accessable to the cpu like "tow-boot" does. seems like more hardware is required for the "jump drive" option which makes me wonder why someone would use the "jump drive" option?
As explained in my previous comment, "Tow-Boot" is the bootloader based on U-Boot (see https://tow-boot.org/). It has a USB Mass Storage mode started with the volume key at boot. Flashing with Tow-Boot is only possible if you installed it to the boot medium (microSD card, eMMC) on the regular PinePhone (not the Pro).
Jumpdrive is a tool to expose the eMMC to the computer, which you can boot from microSD card.
