Was this 5.8.11 the out-of-the-box firmware? Or did you get it via an OTA update?
With currently selling Kindles, there are good chances that they
might be downgradeable, sidegradeable, or even upgradeable
to factory build firmwares. As long, as they didn't get an OTA update... As for currently selling PW3s: 5.8.9.0.1 MUST be used. Don't fiddle around with the very old 5.7.4!
Your report means for me: Your device
was re-flashable with a factory firmare. But it got bricked, as you've used the too old one with a too new hardware revision... I case of a non downgradeable fw, the factory firmware file will simply not be recognized as valid - the UYK menu entry is grayed out then...
