FIRST: This brew is ONLY ONLY ONLY for NEW 2.71 TA-082/TA-086 PSPs which haven't been downgraded yet.

This Downgrader improves on Dark_Alex's original TA-082 downgrader by minimizing the keys corrupted in the process ONLY to those required to run FW 1.5 (hence, "Corruption-free").

READ THE README!!! Also, READ THE RELATED ARTICLE ON QJ.NET FOR OTHER IMPORTANT WARNINGS!!! (look for this app in the title) There isn't enough time in the world to duplicate instructions, and besides, reading the Readme must be developed into a habit.
