Nothing jumps out at me and says: "THIS IS IT!"
The early failures to setup lipc seem strange, but I **think** I have seen those before from a device that is working normally.
The recent thread about using fastboot to recover an erased Kindle PW-3:
https://www.mobileread.com/forums/sho...d.php?t=269099
has a lot of serial I/O capture logs attached to it.
(Which I think you have seen, your post reads as if you have anyway.)
Read through yours above and some of the later ones (after we used the recovery menu to re-load the factory Update image) side-by-side.
Clip out and quote any differences you find.
Keep in mind that since it is a different device, there may be minor filename differences, but they are both 5.6.5
@MadMAXXX : See, I knew we would find a use for all of those log files.
