Hi,
I have my N810 for only few days and today, when I tried to install mplayer and other application, system doesn't give me a permission to write into an Internal Memory (/media/mmc2). I don't know what happened with the permission because I can't remember I did something with it. But now, I can't create anything in there. Mount options are here:
/dev/mmcblk0p1 on /media/mmc2 type vfat (ro,nosuid,nodev,noexec,uid=29999,fmask=0133,dmask =0000,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8)

I wanted to try to edit fstab but I don't know how to get root permission to edit it.

Can somebody help me please?

Thanks a lot...

For some reason, on soe N810s, the filesystem isn't formatted to the right size of the actual flash storage. When Linux detects that, it puts the the filesystem in read-only mode. the easiest way around is to re-format the internal flash disk. - either from within the file manager or when plugging it into a desktop computer and formatting it from the desktop. if you previously had swap enabled, you might have to reboot first and hope the os can disable the swap before linux detects the formatting problem anc puts the drive into read-only mode again (and thereby preventing the disabling of the swap, necessary for reforrmatting or external access from the desktop)

Thanks. I've already solved it by this article.
