TA-082 Downgrader minimizing keys corruption">XsavioR of the Exophase forums has released this 2.71 downgrader for TA-082 and TA-086 PSPs, tagged "Corruption-free". At the end of the entire procedure, whose instructions can be found in the Readme included in the package, the result is a FW 1.50 PSP
The "Corruption-free" tag comes from this 'brew's feature which eliminates superfluous corrupted keys from the first generation of idstorage patcher. It will only corrupt those keys necessary to run FW 1.5. As it's also integrated into one package, this downgrader saves the newly-initiated into homebrew the trouble of "even knowing what idstorage is," XsavioR explained in the Exophase forum. This package also includes HEN-D, necessary for the downgrader process.
There is almost no way you can brick your PSP with this! Great App for any newbie incoming to PSP scene
