Can you trick the PSP to think it has a different firmware?

[Mr.Denny]

Consider this situation

What if i upgraded to 2.70 eventually because upcoming games i wanted demanded it but i still wanted to play my homebrew. If that was the case, could i trick the PSP to think its still has 2.60 firmware?

Probably a stupid question but i thought i`d ask.

Thanks :)

Nope, 1.5's can be tricked up to a 2.6 and 2.0's can be tricked to a 1.0, no 2.01+ tricking yet.

[Mr.Denny]

Oh, i see.

Thanks ;)

would it be possible to encode an eboot into flash-format applications than run it on firmware 2.7? if so than that could be a possible way for downgrading

[mesosade]

or...you could somehow change the url that the network update uses so it updates to a fake-value upgrade thinking it's 2.whateva whereas it could be 1.5

[mesosade]

my last idea would be probably impossible but anyways how about creating an eboot file that actually contained a replica of the psp browser that you could run eboots of that? (dam i need to write this down)

[jrsmaster411]

with x-flash u can change the number in 1.5 to any number up to 9.99 but it still doesnt let u play anything higher but still funny to see it say 2.70 when it's 1.50

need help on sons psp, can someone tell me if on version 2.0 you can play new games suggesting and upgrade to 2.6? and on umd movies are they region fixed as have one ssays sorry wrong region code? can i get round both or neither?

[nesianstyles]

lol, triple post from you mesosade.
1. No there is no way of running an eboot through flash. Also, flash is another language called action script.
2. Nope, changing the update path isn't going to help one bit. You can download updates and put them on your memory stick but it won't let you downgrade. It would most definatly check firmwares before it started.
3. ? didn't quite understand that, but it is impossible to run an eboot through the browser.

[mesosade]

just a noob trying to help :P
