Right, so I've got the Paperwhite 2nd Gen with a serial number starting with 9017. As with many other people, I have an issue with the Update button being greyed out. The Snapshot files in
https://www.mobileread.com/forums/sho...d.php?t=225030 do let me update, but I have a feeling they're overwritten immediately.
So here's my scenario. I install the Jailbreak update, then I add the MKK bin file (again from the Snapshots link), update, the device restarts, and then I try to install some kindlets like the Collections Manager (which I put into /documents), but it tells me that the application could not be started. This leads me to believe that it seems like the jailbreak and updates worked, but somehow the Kindle is overwriting it.
I'm on update 5.4.3.2, by the way. It should work, but i'm not getting it to.
