At this moment I have done nothing. My "problem" is that I charged my Kindle PW3 after 3-4 months, for some reason I switched off the airplane mode and my kindle got updated OTA (my bad that I didn't block this feature). So it was updated from 5.8.x to 5.9.4 in a while. Then I want to switch on screensaver hack for cover mode, but the old KUAL (dev) didn't work. So it was neccessary to install KUAL (nomax KOA2). I had updated python and linkss etc. Everythink is now working on 5.9.4 but it is not possible to uninstall the old version of KUAL so I have now in collection 2 KUAL (doc and DEV). DEV version is not possible to launch.

So my plans are to downgrade fw to some of 5.8.x versions, install KUAL and block the OTA updates for future. So now I need to find out how to do it.

Just for sure, I am reading threads on this forum for more information because I don't want to brick my Kindle. That is also the reason why I asked "you all" here for advice.
