PW5 how to restore this kpw6

MYY · Today, 11:08 AM

KPW6, firmware 5.19.6, Véra jailbroken, hotfix installed. Boot loop / white screen after adding two files: /etc/udev/rules.d/99-bt-keyboard.rules (contains ACTION=="add", SUBSYSTEM=="input", IMPORT+="/usr/local/bin/dev_is_keyboard.sh %N") and /usr/local/bin/dev_is_keyboard.sh, followed by udevadm trigger. usbnetlite was NOT installed. The USB drive was visible for a while, now it no longer appears. I've placed /mnt/us/emergency.sh with the removal commands hoping the bridge companion job picks it up. Questions: (1) Does kmc.conf's start on framework_ready ever fire if the framework never comes up — is there a job that runs earlier that reads from /mnt/us? (2) Does PW6 have accessible serial pads? (3) Any way to trigger an official firmware flash without the UI?

If you can’t drop any files to USB, and have no usbnetlite, this is it. Modern Kindles (PW4+) have no serial access
Sorry

Why do you even put these files manually?
If this is for kindle-hid-passthrough, you should have used the complete tested package from the latest releases

If you manage to drop files to USB, either try dropping the full firmware from https://ftvdb.com/

or a file called DO_FACTORY_RESTORE

You have a really slim chance of catching USB windows to transfer the file (maybe try vibe coding with Python)
