PSP 해커팀은 최근에 구입한 SXT Firmware Flasher 를 가지고 한가지 실험을 했다고 합니다.

그것은 순수한 1.5 펌웨어를 별도의 조작없이 1.0 펌웨어로 만든 것입니다.
(다운그레이드라고 할 수 있지만 별도의 1.0 펌웨어를 이용하지 않은 방식)

이것은 무엇을 의미하느냐?

바로 개발자가 독자적인 PSP의 펌웨어를 만들 수 있다는 것입니다.

현재 PSP 해커팀이 커스터마이즈된 펌웨어를 개발할 예정이고, 이것을 설치하면 소니에서 만든 모든 보안장치가 무력화되고, 사용자가 마음대로 PSP를 개조할 수 있답니다.

(설치방식은 일반 업그레이드와 동일...커스터마이즈 펌웨어를 정품 펌웨어로 인식해서 자동으로 업데이트될 것으로 추정됩니다.)

예를 들면 UMD지역코드를 무력화시킨다던지 개발자들이 만든 Homebrew프로그램이나 에뮬레이터도 별도의 로더 프로그램 없이 쉽게 돌릴 수 있습니다.

펌웨어를 조작할 수 있는 SXT Firmware Flasher 프로그램은 용량이 커서 PSP 자료실에 업로드했습니다.
필요하신 분은 다운로드 받으시길 바랍니다.

단, 이 프로그램을 이용해서 직접 다운그레이드를 하지 마세요. PSP가 뻑납니다.

Recently we brought you news on the SXT Firmware Flasher. Well now we have some big news regarding it.

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.

EDIT: 4 MORE confirmed reports of untouched 1.5 firmware PSPs being downgraded to 1.0 successfully have been sent to us. This brings us to a total of 100% downgrading or 9 out of 9 successful attempts. Expect a video of the whole process coming soon!

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.

DO NOT USE ON A UPGRADED/DOWNGRADED 1.5 PSP. IT WILL BRICK.

To use it, 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.
