You have to create md5 files with md5 hash of the saved files (using, for example this or any other utility http://www.winmd5.com/) you only need rootfs and fsk.

Download installer, in PRSPInstaller\Sony Reader\software\firmware\505\ replace:
1) Fsk.img with corresponding backup file
2) Edit Fsk.img.md5 and put updated hash info there
3) 1.1.00.18040.root file with corresponding backup file (1.2....)
4) Edit 1.1.00.18040.root.md5 content accordingly

Then start PRS+ installer, go to advanced settings, force flash root fs then force flash fsk.

That should restore your UK firmware.
