chmod 777 /tmp might be YOUR friend, but it's not mine, nor is it a
friend of any other user on the box. On a box where /tmp isn't borked,
chmod 777 /wrong
ls -ld /tmp /wrong
and notice the difference between the permissions on /tmp and /wrong .
What is really your friend, and the friend of all users of the box, is
chmod 1777 /tmp
which allows any user to create files in /tmp, and only allows THAT
user to erase those files.
For Andres problem, without knowing more details, he could boot in
single user mode, and do
mv tmp bad-tmp
chmod 1777 tmp
