Re: 5.12.2 jailbreak steps done - downgrade now?

Hi,

I've read through the various posts and done the following (mainly https://www.mobileread.com/forums/sh...d.php?t=267541) with some minor modifications. I've detailed what I've done in case it helps someone else.

1. Set up a 1.8v serial to usb device
2. Removed my KT2 device from its frame and expose its serial debug slot
3. Manually held pins down with my hand onto the Tx/RX points (making sure to only touch the plastic bits). I taped ground to one of the heatsinks.
4. Connected via Putty after changing baud rate
5. Pressed 'd'- diagnostics inaccessible. So 'exit login' brings up the username/pw prompt
6. Accessed root after figuring out my password (not necessarily fionaxxx, I've found) and changed /tmp/main/etc/passwd
7. Ran jb.sh from "kindle-jailbreak-1.16.N-r17396" in the folder "JailBreak\kindle-5.4-jailbreak"
8. Installed "KUAL-KDK-2.0.azw2", "Update_KUALBooklet_hotfix_v2.7.24_install.bin ", and after that MRPI from "kual-mrinstaller-1.7.N-r17940".
9. Added the partial download folder to Kindle root and disabled on the air update through KUAL helper

Q1. Context: I wish to use the KT2 with WiFi on as I want to use Python to display images being pushed from a webserver (I already have python and usbnetwork installed). My question is that since I am on 5.12.2 is the KUAL helper and partial download folder enough to stop updates or should I downgrade the firmware?

Q2. If so, I've been through the factory downgrade instructions but this isn't clear I think. I've downloaded "update_KT2_5.6.0_initial.bin" and from what I understand I should run this as 'update you kindle device'.

Q3. Also, before I write it, does anyone have a Python script that pulls images from a webserver? I've found that pjimenezmateo has an interesting github project here "https://github.com/pjimenezmateo/kindle-wallpaper/" that does something similar.

Thanks.
