I've done that, but still get the error when I try to open the KUAL document. Tried various solutions presented here, but it's hard to know what's still relevant.

I've got a Kindle Keyboard 3.

It looks to me as though the current set of archives need to be updated as something has timed out. Is this planned?

I'm probably not going to spend any more time on getting KUAL working, as I suspect it doesn't add much for me. I got launchpad and KOReader working, and will probably look at Calibre integration and USBNetwork next.

I found a temporary solution until developers pitch in to correct the issue.
This is the only solution that worked for me on KPW1 after 3 days and multiple resets. Upgrade to 5.6.1.1 finally after everything worked for me.

Brother!

Your advice saved me from turning gray haired too early!
it was updating firmware to 5.6.1.1 that solved the issue of the "signature" error.

as of 15 of June 2026 I confirm the above described methodic has allowed me to lunch Kual and install KOReader on my PW1 with 5.4.4 firmware.
