It was Pomtroll, asking for the 350-version.

installing PRS+ (with the ..setup.exe) should be a straight forward process.
Please check the "About" screen after installation.
If all went well, the first screen of About will show the PRS+ fw-version. Also the third row of home-screen will look different with PRS+
Browse Folders instead of periodicals
and More instead of ....(don't remember, sorry)
There is a "glitch" at least with 350/650.
After installing PRS+ all looks and works as expected.
After the first full shutdown and restart the standard UI will show up. (Maybe you got this effect)
Just do another full shutdown restart and PRS+ will show up again.
(Added this as Note2: on the
PRS+ project homepage wiki installationguide, too)

PS: I remember you wrote about a boot-loop with PRS+, so it may be be wise to backup the content of IM (Internal Memory) to your computer, format the readers IM and try the PRS+ installation with a "clean" system
