My 6th downgrader idea

[psycx]

It said "The update failed. The memory stick was removed." Can this be hacked in the updater program so that the memory stick removal doesn't trigger this?

If anything could be hacked in the update program we'd have a lot cooler stuff than downgraders

I am racking my brain for possible ideas.

Still thinking...

OK! Can anyone give me that bogus 1.00 update if they can find it?

i thought of another idea

What if someone made an index.dat that could not be overwritten, so when the PSP updated, the file would be the same? i.e. I have version 1.50, use a version changer to change to permanent 1.00, update to 2.50, still thinks it is 1.00, downgrade with 1.50 update.

What do you all think?

I think we should wait and see what happens with the GTA exploit soon.

nice! make the index.dat not be able to be overwritten by encrypting it or somthing
?

Man I am so tempted with this, has anybody tried it? it's been 10 days since this was posted.

[Fanjita]

The INDEX.DAT file is already marked as read-only by the system, which write-enables it during upgrade.

So, nice idea, but I don't think it can work.

I meant the swap trick. anybody been brave enough to do that? or is that a dead duck now..
