Code:
Yes, that is right! Another downgrader is in progress as we speak. Yoshihiro, Mathieulh, and Dark_Alex are currently working on a downgrader that will allow you to downgrade your 1.50 to a 1.0 PSP! This was the first firmware that made it onto the PSP, and was only available on Japanese PSP's at launch. This first firmware was, and still is the only firmware that will allow us to run unsigned eboot files without any exploits. Nem was the first to release a homebrew application in the classic form of a "Hello World" application. The one benefit for this downgrade is the ability to run unsigned eboots, and ultimately hacked firmware. This means that, like the Undiluted Platinum modchip, we will be able to use custom firmware as our firmware. This downgrader has been tested by FreePlay and Dark_Alex to work, so all looks promising!

Mathieulh, Yoshihiro, and Dark_Alex will be releasing this downgrader tomorrow if everything goes to plan. We will inform you all when the downgrader comes out as fast as humanly possible. In the time being, feel free to check out the talk as it happens in Fanjita's IRC channel. You can access this by opening your IRC client, join the irc.dashhacks.com server and join the channel #noobz.


looks yummie Very Happy

Video : , Is there any point in downgrading to 1.0? I might do if it gets rid of those annoying currupted icons...

But will all the homebrew still work? , And does KXploited homebrew still run on 1.0's?

Quote:
nstructions for the 1.00 user:

- Copy the downhelper100 folder to /PSP/GAME/ and start the program.
- It will dump your flash and your ipl to the memory stick. After finished, the program will exit.
Send the folder created at the root of your memory stick called "DOWNDATER" to someone with 1.50 to allow him to downgrade.

Instructions for the 1.50 user:

- Copy __SCE__downdater100 and %__SCE__downdater100 to /PSP/GAME/
- Get the DOWNDATER folder from your friend with a 1.00 version PSP and put it on the memory stick.
- Get the official Sony 1.50 update and put it under /PSP/GAME/UPDATE
- Start the program.
Note: You need to set the language of your psp to either english or japanese before starting (anyways, it will advise you if you don't have that requirement and it will exit safely). Also, connect the PSP to the AC adaptor.
- After a confirmation with the X button, you PSP will start to flas to 1.00.

DO NOT REMOVE the memory stick and DO NOT shut down the PSP.

After it is finished, the program will tell you to restart the PSP manually, and you will have a 1.00 PSP. Remember, this will flash your PSP's flash memory and you could potentially brick (break) your PSP.

I hear ISO loaders don't work on this firmware... *Stays on 1.50* Very Happy

Quote:
Please take note. This downgrader is not of immediate use to the normal end user (like myself) this will downgrade to 1.0 but will not allow the broad use of iso loaders yet. It will eventually lead to a revolution as it gives complete access to the psp hardware

iso loaders will need to be rewritten.

I think the above comment hits the nail on the head, this will in time help, but for now.. we should stick to 1.5.

Are you sure? If so.. then why has this not been done already for the 1.0 users then?

For example could we make a "custom firmware" that could autostart a peace of homebrew upon bootup? A bit like the Xbox softmods using Evox.
