All these patches and repacks require a new flashing, so unfortunately your books will most probably be lost.
As I see it there are two possibilities: either you get the IQ hooked up to you computer (or someone elses) by using
PDA NET and save your books that way,
or you try to get "Z4ROOT", an app that allows you to root your IQ (i.e. gaining administrator rights to see all parts of the operating system and change values there iso only seeing most parts without real access) thereafter you can copy and paste nearly everything by using "RootExplorer"
If you have read the whole thread about the repack you might have found
my uploads to get all you need, if you require more help PM me
