I have firmware 5.4.2 and I am quite confident BackDoorLock will prevent silent update to 5.4.2.1.

Just discovered that with the backdoor lock enabled on a PW2 with the latest firmware (5.4.3.2) Amazon are still able to remotely remove books from the device.

I assume the lock is only for updates, is there any way to prevent them from remotely killing books on the device?

You assume correctly.

It is intended for users who believe in "My device - my rules" principle.

It doesn't stop Kindle from downloading the update file but once it is downloaded, any silent installation attempt fails instantly in an early stage without depleting the battery and intercepting the GUI.

...

Here is how it works:

It replaces the line
Code:
_UPDATE_WAIT="/usr/sbin/updatewait"
in /etc/updater.conf with this one:
Code:
_UPDATE_WAIT="$(if [ -x /mnt/us/backdoorlock/updatewait ]; then echo /mnt/us/backdoorlock/updatewait; else echo /usr/sbin/updatewait; fi)"
Wrapper script /mnt/us/backdoorlock/updatewait passes any calls to /usr/sbin/updatewait but only if called with parameter -i (immediate/interactive) - that's how "Update Your Kindle" calls it.
OTOH silent updates call updatewait without any parameters and such attempts are intercepted and logged to /mnt/us/backdoorlock/update.log or /mnt/us/extensions/backdoorlock/update.log .

On KT and KPW lines
Code:
legacy.GET.FWUO=com.lab126.ota
legacy.GET.FWUP=com.lab126.ota
are commented out in file /etc/todo/handler_registry.conf

Does this hack still not work with PW1 on firmware 5.4.4.2?

Oh I must've misinterpreted dsmid's original post where he posted, "Silent update detection does not work on Kindle Touch and Kindle Paperwhite as the hack uses a different method to stop silent updates on these devices."

Implies that the hack works.

I assume what doesn't work is the report card about the successful blocking.

I while back I backed down to 5.4.2.1 because that enabled me to use CM and Calibre/Collections Plugin and I'm happy with what I can do.

Will the BackDoorLock prevent any automatic updates while I'm at this level?

Hi,
I had to re-install some stuff on my KPW2 after an update. So I thought I'd install the backdoor lock too this time. But I didn't get the option to update the Kindle (greyed out). Probably this one doesn't work for my Kindle?
I had the same problem before with Python and Screensaver hack, for these I needed the newest snapshots. So maybe my Kindle is too new? Will there be a backdoor lock that will work on my Kindle? Thanks!

EDIT: extra info:
first 4 characters of serial number: 9017
The firmware version is 5.4.5.1
