Glad you like it, but there is no need for uninstalling before update. All PRS+ updates or branches - like PRS+Zork Edition - can be put atop each other. Also stepping back from higher to lower versions, say 2.1.01a to 2.0.18 can be done at once.
All installer packages will contain a folder PRSPInstaller. Copy this folder to the IM (Internal Memory) of your reader.
For 300/505 a installation menu will show up upon disconnect from USB.
For 600/x50 shut off the reader and restart. Update will be installed while restarting.
Sony changed the underlaying OS from x50 to T1 from Montavista Linux and Kinomas FSK-framework to Android. So PRS+ can't be ported. It would be a complete rewrite in a whole new environment. BTW rupor is doing a great job for T1/T2.
