So, my PSP 1.52 is comming today according to FedEX. I was reading and googling about how to upgrade and downgrade the firmware. I found a couple of guides but some had a little bit different information then others so I though I would write out what the difference is and see if anyone can help me out.

# Go to the Photo icon on your PSP and scroll through the pictures to get to overflow.tif. You do NOT have to press anything. It will start automatically. Two strings of letters/numbers will appear. This is normal and good.
# Wait AT LEAST 30 SECONDS and then turn off your PSP by holding the power button up until it fully shuts down. Then, start your PSP again.
Now the Wait AT LEAST 30 SECONDS is what is different from here,

Step 5: Navigate to Photo then Memory Stick via the PSP’s menu system and start scrolling down through your photos until you reach the overflow.tif picture.

You’ll know you’ve hit it when everything freezes and you get a black screen with a bunch of white text output.
three
If your PSP freezes without going to this black text screen, then hold the power button for about 10 seconds until the PSP shuts down, then hit the power button again to start it back up. Repeat this step until you get that black screen.

Now that method doesn't say you have to wait 30 seconds at all which is why I am posting.
I also have one more question, the psp-hacks had a download link for 2.0 upgrade from 1.52, to do that all I have to do is put the EBOOT.PBP from the 2.0 on my memory stick by creating a folder called UPDATE inside /PSP/GAME/ and then what? Load up my psp and go to Games - Memory stick and then hit "X" and the upgrade will start??
