Fw1.0 Backup and Restore Tools


That mad scientist 0okm is at it again. And this time, it's something pretty revolutionary. He has just managed to write a program which can flash your 1.5 PSPs to 1.0, provided that you've backed it up using his tool. This isn't a true downgrader since you can't actually downgrade your original 1.5 PSPs, or even the 1.0s unless you've backed up your firmware with it. But if you're one of those lucky people to still have a 1.0 PSP, rejoice! You can actually take a trip to the 1.5 firmware, and come back home to 1.0!

How is it possible? Well, in simple words, it's just copying the firmware to the memory stick and later, just re-flashing it again. But then, why wouldn't a normal firmware file work, like in the 2.0 downgrader? Under the circumstances, I'll assume that all the files in the flash are somehow encrypted differently for every PSP. That's why it isn't accepting files from a different PSP. It will only restore your firmware if the backup is taken on your own PSP.

And this comes from the guy with the multiple firmware hack which we covered some time back. Seeing all his wacky projects, I'm pretty much sure he has a bunch of stuff up his sleeve. What exactly, I can't tell you because I myself don't know. But whatever it is, I'm waiting with bated breath. For now, enjoy this backup and restore tool for your 1.0 PSP.

The download file is locked by a password. You should open the attached README and find it out yourself since it carries an important message. Please make sure to read the README because it also mentions a lot of info which you should be aware of before embarking on this adventure. And as with every firmware tool, it is risky. Make sure you know what you're doing. Neither 0okm, or QJ.NET accepts any responsibility if you burn your hands badly with it.

But if you're still dying to try it, download it using the link below. And thanks for the tip i386!

WELL DONE!

sorry, n00b question but..
whats the advantage of 1.0 vs 1.5?

   by DiabloTerrorGF - 2006-05-23
 » #1

Quite possible, but first we need to get more than the limited usermode that's available for 2.01+.

I wouldn't risk it right now though.

looks like we have some good progess here. slowly sony, we inch closer to the ultimate goal of ultimate downgrading for iso capability! mwhaha!

Please don't upgrade upwards of 2.0.
And if possible, not even above 1.5. Nobody can guarantee the results of this tool if you go over 1.5

props to this guy. made it easy for all those 1.0'ers that never wanted to update. 1.0 & 1.5 oooo !!!

   by photoboy (Unregistered) - 2006-05-23
 » It's good but...

there's not much point in upgrading to 1.0, there's only a few extra games that work with it. Most games now need 2.0+ so you're knackered whichever firmware you use (at least until a new loader is released anyway)

 » upgrading to 1.00

You'r not realy upgrading or downgrading to 1.00, you'r just restoring your flash from you'r origional 1.00 firmware
the only reason anyone would do this is so they can upgrade to 1.50 in the knowlage that if any custom firmware comes out (most likely any custom firmware will only be usable on 1.00)
they can replace the origional flash.
1.00 isnt better than 1.50, the best way to describe it is 2.00 without the webbrowser and any new game support etc. but homebrew is accessable through game menu without any exploit.

 » Is this possible?

Isn't it possible if someone backed up their 1.0 files and hosted it on the internet so a person with 1.5 PSP could copy the 1.0 files to the memory stick and downgrade?

That's neat...but if only it worked on ALL 1.50 firwares to downgrade to 1.00 firmware... Either way though, eXcellent WORK!!!

There is a Backup of a 1.00 somewhere just have to find it (dont google go to other psp news sites)

   by Illegal Machine - 2006-05-23
 » nice progress

But Pretty much useless to like 97% of the people who are lookin at this..


I suppose theoreticly, one could go all the way up to 2.0 with this.. Backup, upgrade to 2.0, downgrade to 1.5, restore with restore tools.


but then again, if its only good for 1.0 users who cares I guess...


at least this gets people one step closer to being able to downgrade to 1.0

 » Good Idea

Good Idea but only if it came out like a year ago, I think most people who had 1.0 psp's is already at 1.5, but its better late than never ;)

   by SRD (Unregistered) - 2006-05-23
 » Question

If you have a 1.0 PSP, is it possible to upgrade any further past 1.5 and then back down, or is 1.5 the limit?

Also I thought that when you use the 2.0 downgrader, your PSP becomes 1.0 until you upgrade to 1.5. Is this not true 1.0 or something? Did Sony ever release 1.0 PSP's in the U.S.?

 » He is working on downgraders like this

I remember he is going to make a downgrader by using the mobo board.

 » tight

this is cool. You should compile this one and the 2.0-1.5 downgrader all in 1.

   by soopergooman - 2006-05-23

3. Start work on 2.6!

Go you *****ing Genius!

 » I like the idea

This is somewhat of a good idea but I kinda see it pointless. I mean both 1.5 and 1.0 can play homebrew right so why upgrade and downgrade. Maybe just to play some iso's or homebrew then yeah I get the idea but still.

 » What about higher firmwares?

Could something like this be done for 2.x firmware? For example, 2.0 > 2.60 > 2.0?
