Do we know what Amazon patched out of the firmware to prevent downgrading after 5.8.7? I've been trying to figure it out by comparing different OTA bins using NiLuJe's KindleTool but I haven't found anything. I'll probably end up doing the serial port method (I'm on PW2 firmware 5.10.3) but it would be nice to figure out a software jailbreak again.
