2.71 Downgrader Released, Tested!
Using the recently discovered libTIFF vulnerability, Dark Alex has done
it again by successfully testing and releasing a 2.71 downdater. This
is a direct port of his 2.50/2.60 downdater so it functions the same
way only without GTA. For those of you with TA-082 motherboards, this
downdater will not work. But rest assured, for 0okm is working on his
softdown method for the once thought to be cursed PSPs.
Please
realize that you use this utility at your own risk. This utility can potentially damage your PSP beyond repair.
I was able to execute the
downdater successfully. It crashed on the first try but exected on the 2nd to
successfully downgrade my 2.71 PSP!
Download the downgrader now in my homebrew software library. It comes packaged with the needed 1.50 helper utility to dump the firmware from a 1.50 PSP.
