TA-082 downgrader

As of December 27th 2006, TA-082 motherboard PSPs with 2.71 firmware can downgrade to 1.50. After you downgrade, you are able to install custom firmwares SE and OE. I have tried the downgrader with both of my PSPs and it does work. After that I upgraded one of my PSPs to OE-B and the other to SE-B''. Download the Easy TA-082 2.71 Downgrader, extract the files to your PSP and:
Step 1. Run Hen D
Step 2. Run TA082 IdStorage Change
Step 3. Run PSP™ Update ver X.YZ
