Is there any easy and quick way to get to N810 the missing files that are needed for the installation of new applications and their updating? I do not want to make the flashing operations of http://wiki.maemo.org/Updating_the_tablet_firmware .

I have N810, and its latest updating of OS2008 was done online to v. 4.2008.30-2. The installation of OS2008 Feature upgrade and Almost TI , and the upgrading of maemo-mapper and MPlayer-Plugin fail. Each installation end with an error notice about a missing file. Among them are:
libhildonfm2 (=1.20,5),
pre-installed-documentation-rx44 (=5.4),
libc6-dev | libc-dev (for libhttrack-dev).

I have installed several applications and tuned the N810 for WLAN etc, and do not want to spend one or two days of my holidays with flashing etc - I'm a newbie with OS2008. This is why I ask whether I could add the missing files somehow to N810, and then continue trying to install the applications and to make some updates. If yes, from where could I download the above files?
