Copy all contents inside MS_ROOT to the root of your memory stick. Change the language to English, under System Settings -> System Language See the enclosed Downgrader_HOWTO.txt for details. You can also use this HEN to run a downgrader, which will automatically perform any necessary idstorage patches and install v1.50 firmware on your PSP. See the enclosed idstorage_release.txt for details. It allows you to restore your PSP's idstorage to its original factory settings, so that it can be upgraded to official Sony firmwares, if required.
Note that this package also includes a key restorer for v3.11 HEN - this key restorer is designed for TA-082/TA-086 motherboard PSPs that have previously been downgraded to v1.50. It does NOT rewrite any existing file in the system, it writes new files, so the probabilities of bricking are practically null. Note: this program writes some small files in the flash, ONLY the first time is executed. This is based on the source for HEN 2.71 provided by Dark_Alex, thanks for the code and the help. It makes a patch that remains permanent until hardware reset. This program enables homebrew and downgraders to be run on 3.11 using the US or EU version of lumines.
