I think wrag needs to change his original post and say it will work only with 2.00..

[Accordion]

no the thread is called
2.0 to 1.5 downgrader.
it is pretty obvious what the thread is about
some silly people seem to think that a downgrader whould be kept secret

hi guys,
This is my first post so be gentle. Just bought my 1.5 om ebay and upgraded it to 2.0 firmware (cos there was a thing that said click here to run update so I did. Now I've read a bit more and decided to go back to a 1.5 but it did not work out quite right so I thought I'd start again by going back up to 2.0. However, it got to 97% complete and froze, so I switched it off after a wee while. Now, when i start it up (with no demo disk in it) it makes a little noise, says the date is 1/6 0:12 and then powers down. Is this dead or can it be fixed? If i start it up with the demo disc in, it seems to launch insofar as it will buzz occasionaly, and will also sometimes actually play the demo disc fine. So whats the story, have i killed it or is their a fix.

Have you tried using the power lead when you turn it on? And where did you download the downgrader from?

[ultralord]

Yes, tried just now with the power lead and no different. When I did the second upgared to 2.0 it was powered up via the usb cable, is that significant? the downloader came from a link off psphacks, the file was called EBOOT_Loader_v_09.zip and i pretty much unzipped it and followed the instrauctions. One other think, every time i booted it up, until I changed the file in the Photo directory, every time i went into the photo directory from the psp, some gameof pong would automatically launch, is this significant as well?

[Zion]

Very significant. that sounds like a dodgy downgrader! Download the downgrader from this website. And the 2.0 and 1.5 update files from the official psp website. And have the power cord in while your doing it. not the usb way!

[ultralord]

I'd love to have another go the power chord way- just how do i get the psp started , I have no menu, nothing to choose, it just powers down after 30 seconds?

[Zion]

Try starting the psp without the memory stick in.

[ultralord]

Nope, still no good without the memory stick. It starts, shows the the sony splash screen, then a standard background with the date (1/6) and time. The time is actually corrent, 1:11. Then it goes off a few seconds later.
