Hi....
I am new here.
Need some help with my psp.
I updated it to the 4.05 firmware.
How am i going to access my games??
Or how can i change it back to the 4.01m33?
I'm sorry to say,but that's a very silly thing to do.Now that you've upgraded it from 4.01m33 --> 4.05 official firmware,you can only revert back to your previous firmware(custom firmware) if you have a Pandora's Battery.
Read the following Pandora's Battery creation methods,and tell me which ope suits you best.
1)Softmod the battery
-This requires you to have access to an ALREADY hacked psp a.k.a homebrew capable
2)Hardmod the battery
-This involves you cracking open the battery using a pick or anything like that,and snapping off a pin.(Very risky process,and you might cause injuries to yourself if it's not done right (No joke,i'm serious).This method might also take a couple of tries before you can get it to work,and this means....more batteries and a complete waste of money.
-Remeber,do it wrong,and your battery is cooked.
If you ask me,i'd go with the 1st process.It all depends on ya'

If you don't have any of the above,get an original battery and a genuine memory stick and give it to someone you trust in the forums.They will convert it into a Pandora's Battery.

When i updated my psp to the 4.05 firmware i cannot access the recovery setup anymore. what should i do?
You can't access recovery mode on official firmware psps.Why? Because there isn't one.
