Locked out of system (ncurses, zsh, ssh)

I had my raspberry pi running with archlinux for quite some time now. I had installed ohmyzsh over bash for shell.
Today i updated rtorrent, and as soon as after that, i got errors regarding libncursesw.so.5. So i updated ncurses as well.
Unfortunatelly i had to restart the system, and now i cannot login because zsh uses ncurses. I cannot ssh as well, although i tried these things
1) I removed /usr/bin/zsh to /usr/bin/zsh-backup and soft-linked /usr/bin/bash to /usr/bin/zsh
2) I deleted /usr/bin/zsh and copied /usr/bin/bash to /usr/bin/zsh

I did those things while i mounted the sd card to my desktop. But still, when i put it in my raspberry and try to login with ssh i get:

$this->bbcode_second_pass_code('', '

')
What can i do?

And yes, bash also uses ncurses, so i won't do much if i switch to bash.
I wonder, what happened...

Ok, i think i updated ncurses but all the other programs, including bash, zsh were not updated before the restart.
So they could not work with the new library, because the version that was installed had to work with libncursesw.so.5
I mounted once again the sd card to my desktop (under /mnt) and run:
$this->bbcode_second_pass_code('', '
cd /mnt/usr/lib
ln -s libncursesw.so.6 libncursesw.so.5
')
and i logged in the system. Now i'll update and remove the softlink above.
