Remarkable 2 requires a bit of parts and possibly soldering (but not required, just might make things easier if you don't have pogo pins with handles available).
Both are fully recoverable unless you do something really impressive.
Physically breaking the hardware through software, for example. I believe there's some fun possible in most embedded designs like the one used in RM1/RM2. Like manipulating power management circuitry, or maybe forcing overheat with disabled throttling, and the like.
