PSP 2.50/2.60 to 1.50 Firmware Downgrader Guide

Posted by Xavier Ashe on July 12, 2006

Recently we reported the the breaking news that Kernel mode in 2.5 and
2.6 had been unlocked by hitchhikr of “hitchhikr SoftWorks” and demo
scene group Neural via The Edge. This was a incredible accomplishment that was previously thought impossible. Fanjita and many other members of the PSP homebrew community have come together and been testing the functionality of the proposed exploit. 

Using
the tools and methods that have been released, we have compiled a
“Downgrader Guide” for those of you with a PSP with Firmware of 2.5 or
2.6 who would like to downgrade to 1.50. 

Materials need:

  • 2.50/2.60 PSP
     -NOTE: IT CANNOT BE A TA-082 PSP, TA-082 refers to the motherboard, here's an easy way to check.
  • Access to a 1.50 PSP or the files available here.
  • Power Cable
  • MemStick greater than 32MB in size
  • Grand Theft Auto: LCS
    -MAKE SURE IT ISN'T THE UPDATED ONE WITH THE 2.60 UMD FIRMWARE UPDATE, IT SHOULD HAVE 2.00 ONLY
  • Fanjita's GTA exploit eloader installed (See readme inside file)
  • Balls
  • About 5 minutes
