Hi, I have JB Kindle PW3 (2016). I did JB long time ago, and everything was working great. I am not sure what was my daily driver FW version. May be 5.8.4 or so. Few months ago, I accidentally updated my PW3 to 5.9.7. Since then Kindle launcher does not starts: "Application Error". Although KUAL (I think it is a booklet) runs, and I can start and use KOReader and apps, that I had before. I just would like to see Kindle launcher running again.

Is there any way to roll back to previous FW version? What If I reset a reader, then flash factory_initial_5.7.4.bin (the one that I used to JB my Kindle), then JB once more, install fix and apps, and then update to latest version in which Kindle launcher would work?
Is is a good idea or I will end up with a brick?
