How do you even get into doing this sort of thing? Reverse engineering stuff is hard and all trolling is either really expensive, or old and no longer developed; with a few exceptions, I'm sure.
First, you have to buy the thing. Second, take it apart. Third, think of ways to break in. Fourth, actually do them. Fifth, swear because you broke it.
Usually there's a UART. Apparently Starlink terminals don't have a UART, so the guy took off the eMMC memory chip (which is basically a soldered microSD card) instead.
