It’s been confirmed that the 1.50 to 1.0 downgrader released earlier today does indeed work.

It has been confirmed that 100% of ‘virgin’ 1.5 PSPs downgrade to 1.0 smoothly.

How do we define ‘virgin’ firmware 1.5 PSPs? If you BOUGHT your PSP with the 1.5 firmware ALREADY on it, and have NEVER upgraded or downgraded since the purchase, then you have a virgin PSP.

Out of 5 tests on these untouched firmware 1.5 PSPs, 100% of them downgraded to 1.0 without a hitch, and with region coding removed.

What does this mean? Devs can NOW start making custom firmware for the PSP. The process used by the firmware flasher is using custom code to
replace the NAND memory with new root files. Therefore, since we are NOT using the upgrade EBOOTs to downgrade, almost ANYTHING can be written to the firmware.

Team SXT, Yoshihiro, and PSP3D are currently working on finding out how to get this firmware flasher to work with all versions of the 1.5 PSP, so that we can have custom firmware for all!

Think about it. All the features on the new 2.6 firmware on a CUSTOMIZED firmware which is made by devs to support homebrew, yet have all the features of 2.6, and more, as we can now incorporate Flash and other codecs, like DivX into our custom firmwares.

Howto:
- Put the two folders in the /GAME/ directory of you original 1.5 PSP.
- Put the .bin file in the ROOT of your memory stick.
- Run the EBOOT from your PSP.

Remember - DO NOT run this if you’ve upgraded/downgraded your 1.50 PSP - you will brick it. This means, if you have upgraded from 1.50 to 2.0, then downgraded back to 1.50 and you attempt to run this downgrader, you will damage your PSP and it will forever be rendered useless. This includes using homebrew which writes to the firmware - PSPersonalize, PSPset, etc… this will de-virginize your PSP.

THIS ONLY WORKS WITH VIRGIN 1.50 PSPs.
