2.80 to 2.71 Downgrader Released

greg | January 2, 2007

Update: 0okm has released his downgrader to the public. If you know what you’re doing, and you’re willing to take the risk involved with downgrading/flashing, then go forth young Jedi — may the force be with you. Download below.


0okm has released a 2.80 to 2.71 downgrader for motherboard models TA-079 all the way through TA-086. Although in order to get a copy you’ll need to email 0okm requesting it — see source link below. Once retrieved, the steps are relatively straight forward:

  1. on FW1.50PSP:
    Download PSARDumper
    Download PSP FW2.71 Update EBOOT
    Download PBP Unpacker

    use PBP Unpacker to unpack FW2.71 EBOOT.PBP
    copy FW2.71 DATA.PSAR to ms0:\
    run PSARDumper on FW1.50PSP then press circle to dump encrypted without sigcheck and decrypted reboot.bin.”
    to Dump “FW2.71 File”
  2. on FW2.80PSP
    Extract FW280DownDate2FW271.zip to ms0:\
    check ms0:\F0 have 286 files and total size is 18,598,267 Bytes
    PowerOff PSP to CleanReboot
    Run xLoader on FW2.80PSP
    then Run 2.71DDforTA-079~086FW2.80PSP

You can fetch xLoader here.

Once successfully downgraded you may proceed to FW 1.50 by using one of the supplied downgraders. TA-082 owners, ensure you use Dark_AleX’s TA-082 downgrader to avoid bricking your unit.

Perhaps we’ll see a public release in the near future.

2.80 Downgrader Released!

greg | December 23, 2006

Holy homebrew-fest Batman, errr I mean, 0okm!

0okm has released the almighty 2.80 downgrader for non-TA-082 users. Yup, this does not work with TA-082 boards, so don’t ask. Otherwise, if you are an existing 2.80 user and wish to downgrade I highly suggest you follow the instructions very very carefully.

USE AT OUR OWN RISK

video tutorial (thanks for the link mwj)

HowTo

  1. Run moonlight’s “FW2.60 DownDate helper” on FW1.50 PSP to Dump “FW1.50 File” or Download “FW1.50 File” from psp-hacks downdater_final.rar.
    Extract downdater_final.rar \DOWNDATER\ all file to ms0:\DOWNDATER\
  2. Run FW150IPL_Dumper on FW1.50PSP to Dump ms0:\DOWNDATER\PRX\FW150_ipl.bin
    NOTE: if no FW150_ipl.bin in ms0:\DOWNDATER\PRX\
    Run FW280DownDate4TA-079 will brick your PSP !!!
  3. Run FW280DownDate4TA-079 By xLoader
    NOTE: Don’t use eLoader to Run FW280DownDate4TA-079 it will brick your PSP !!!

Awesome work 0okm!

Remember, if you haven’t a clue or the instructions seem fuzzy to you, DO NOT use this. Good luck!

TA-082 Breakthrough!

greg | July 27, 2006

0okm has made it apparent that there is indeed hope for TA-082 motherboard owners! As simply stated on his blog:

PSP Multi Firmware module will support TA-082 on NEXT Ver.
so if your TA-082 PSP is FW2.50 or FW2.60
don’t update!!!

What does this mean? Well, by the looks of it, TA-082 owners who are currently left unable to downgrade could very well be on their way to 1.50 freedom! Nothing is available to the public as of yet – rest assure, it’s being worked on and we may see something sooner than later. In the meantime – as 0okm said – don’t upgrade your PSP! Good lookin’ out WiLLiAM.
