Well it starts off really funny. I heard about the new and improved firmware 3.72HX and proseeded to install this into my PSP. I known that HX1 didn't have 1.5 so I waited untill a patch was out BUT! I didn't know that the 1.5 patch was only for HX1. I installed HX2 than installed the 1.5 patch, never tested it since I had no time.
Anywho. I wanted to try DDR today for once and well it didn't work for me. I was liek WTF?!. I redo the 1.5 patch than AFTER THAT I relized what I just installed it and it DOESN'T WORK FOR HX-2. "sdhfisdhyfisdyhfiusdhifu ". I downloaded the recovery files for recovery mode and I had a ERROR while it flashed "ohno!!". I press X to what I think is the end of my PSP life. BUT!! it still works. The god dam thing works still -_-. So I went around the forums and saw one thread (that I'm happy about) that allows you to DOWNGRADE from 3.72HX-1 to 1.5
I do that and it saved me. Thanks!
