Need help with playing games on my ps3 again.

I have a slim ps3 which is not compitable with cfw so I cracked it using HWF(4.89) and HEN.
Just before the official 4.90 update I had to install HWF (4.89) via recovery mode for some reasons. Now in order to play games on my PS3, I have to go online at least once. But the problem is since I am on 4.89, ps3 doesn't allow me to go online and I can get past the "sign up" screen.

I tried to go online by bypassing the update using the method on this link...
