This is for use with Jailbreak

so possible downgrade option?

ugh.. well if it works, yeah..

Sure, if you want to downgrade from 3.41 to whatever.

How are you going to run unsigned code on the 3.50? That's right, you can't.

#im not very good with all this downgrading and stuff, but i downloaded file, but what does it do. it trys to open with adope but wont load :/
p.s how do i downgrade software???

Shiver is right, What you need to wait for is a hacked version of Firmware 3.50 that blocks whatever it is from using jailbreak or a completely custom firmware

Ya the only way this would be helpful is if there WAS a real custom firmware. But don't worry, there soon will be. I can almost taste it, its basically right around the corner.

No this will not let you downgrade but you may be able to run a lower firmware while using the app. It's only temporary and you might have errors... There are other ways to downgrade though such as replacing the flash.

GUYS! The socalled CFW Loader allows us to load a dev_flash from USB! So customizing is limited to that folder! Also atm we don't have the decryption keys for sprx and self files (stored in the isolated SPUs).
so the only thing we're able to mod are RCOs and some other non imporant stuff like the FONTS. There is a way to bypass 3.41 but I can't tell you because it would be patched (and I would get really angry if they did).
Using CFW Loader is like using a LIVE CD of an OS!

I`ve gotten a great idea, Don`t know or its possible.

1 Download the cfw on the ps3 with V3.41
2 Like the mw2 hack you send the cfw to the ps3 at V3.50
3 Load the cfw on 3.50 and test it out

Don`t know or its possible, It`s just an idea.
