Is this correct?

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.

http://www.psp-hacks.com/psp-downgrade.php
# 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??

Remember you first have to upgrade to 2.0.

first upgrade to 2.00

then follow this link
http://www.dcemu.co.uk/vbulletin/sho...hlight=PspSetX
to get pspsetX .

you need to run this through the eloader. go to noobz.eu for any eloader info

get a 1.50 update either on a UMD or download. be sure it is 1.50!

*charge your psp fully, and keep the charger in at all times!!!
*make sure all files are in the correct places
*run the eloader from the photo menu
*run PspSetX
*choose downgrade...it will then trick your psp to think it is a 1.00
*now exit to the home menu
*run the 1.50 update.
the update will start, it might get to 99% and freeze...dont worry, wait at least 30 seconds then hard reset.
*you will get the blue screen, just press the circle button.
*enter your settings and enjoy your 1.50 homebrew!!

What's the difference between the other method and the PspSetX method?

[Accordion]

pspsetX is safer as it runs the flashing app through a stable exploit. you simply select the option to downgrade and it confirms once it has done it.

[Rogu]

Is there any reason why I don't see very much info about it? There are about 5-6 tutorials on the other method but I could only find one other tutorial for PSPSetx.

FedEX was wrong, I get it tomorrow =( Now I need to figure out devhook because I didn't expect to get it so soon!

Has anyone used this from this site?
