What would be stopping someone from manually cross flashing firmwares?

[hanakomisa]

Say for example, if I wanted to flash PW3 5.14.2 on a Kindle Voyage (either through UYK [probably impossible without modifying the update file] or doing it manually through flashing the eMMC), what would really be stopping it from working? AFAIK since both have identical SoCs and same amount of ram, as well as the same screen resolution.

I hope this post is allowed, and I'm asking this question from a perspective of someone who doesn't know much at all about Kindle's own hardware. Would love to learn it more though.

If you try to install the a firmware from a different model Kindle, it just won't work. You won't be able to try installing it.

Other aspects of the hardware are different. People that have forced such installs via the serial port or before amazon had safeguards in place ended up with bricks.

@hanakomisa That particular thing (PW3 firmware 5.14.x on Voyage) has already been done

Ah okay, makes sense, thanks for the answer.

Oh I searched for related topics and couldn't find anything mentioning it, thanks for bringing this to my attention! (This makes me oddly happy for some reason)
