preinstalled books lost while firmware-upgrade
I am using a PRS-505 a couple of days (fw 1.4...) - and did an update with prs-plus.
Unfortunately I deleted the german preinstalled books while doing the upgrade.
(e.g. "Gut gegen Nordwind" etc.)
Is there a legal way to get the books back (perhaps download somewhere)?
(without paying for them)
Thanks for help.
