SE C905 Unlock??

[wozski]

Go to "Settings" and put your username and password. Press "save changes".
Now, go to "Job" tab, choose your phone model, choose "direct unlock(+sec.zone rebuild) at "Security zone operation", uncheck "Repair EROM/SEMC boot", check "show codes", and at "set certificate to" choose "no certificate change". connect the phone while holding "2+5".

I did all the above before reading this however i didnt uncheck repair erom?
will this still be ok?
I have also noticed its not recognising my memory card?
