My KT3 currently runs firmware 5.16.2.1.1, jailbroken using LanguageBreak. Why this happened is simple: I got curious, found out that I can boot my Kindle to DIAGS with the idme command, and just went and typed 'idme -d --bootmode diags' and rebooted. And now it's stuck in the tree screen.
It makes sense though - I have seen that the contents of the partition /dev/mmcblk0p2, which is supposed to be an alternate but valid Linux rootfs, has become sone 'Nhxxxxxx' and 'hjkl' garbage. The kernel might've just panicked upon not finding an init system at its desired location.
So, of course, since what's accessible by the 'idme' command is persistent, just rebooting the device did not help, and now I wonder how I can bring my Kindle back to life (i.e. make it boot to the 'main' system). I'd prefer a method that does not involve opening the device for UART access (if that's even possible).

*I have an ENABLE_DIAGS file present under both / and /mnt/us.

p.s. Is it okay to just connect a random CH340 to the Kindle's UART port and just start typing in the console? I've heard that Kindle uses 1.8V UART while most USB-Serial adapters do 3.3V, and pumping 3.3V directly to 1.8V may fry the deivce
You should be able to do that yes, i used a random one on a pw4 and it didn't hurt it (further)
