Rank up codes

[Shandai]

I ranked up a friend and I only have 1 psp.

----Edit:----
It is simple...

Get a good rank up code.

If you do not have a good rank up code it probably won't work. Again, do not have any other codes on or highlighted or you maybe end up getting banned. Don't be alarmed if you get a 35 error. Just remember to corrupt your psid.
