5.14.1 locked kernel?
Hello!
I connected via terminal to my pw4 running 5.14.1 software and discovered something scary. In this software there is no console for emergency FAT partition sharing and software reload. It looks like the last way to repair these devices yourself has been cut off.
Shame on Amazon!

Yes, but when the device falls into bootloop jailbreak will not help.

recovery-util is presumably still there somewhere as it's needed to apply firmware updates (unless this has changed recently?) - what happens if you keep pressing Enter around this point in booting?

It's not even the biggest d*ck move we've seen from Amazon on the newer models; having Secure Boot enabled and a locked bootloader means that it's impossible to load even an Amazon signed U-Boot or kernel.

Unfortunately, pressing Enter does not give anything. Interestingly, after loading the system, there is also no login screen. I do not know if this was already the case in previous versions of the Android Kindle?

If there is firmware on the fat partition, then after the reboot, the installation is automatically attempted as before. The problem will be when the system does not start for some reason.

Did you guys ever find a solution? I'm stuck in a bootloop on my PW4 (was just running stock fw!) and I'm on a version that doesn't have the recovery mode prompt.

I'd love to just mount the internal storage and feed it a clean image!
