First I'll give you a brief rundown of where I am..... In the process of upgrading from 3.01 OE-A to 3.02 OE-B, my unit suddenly stopped powering on properly. I'm able to get to the recovery console without any trouble but when I try to run the 1.50 downgrader or whatever, it gives me the "Doing preparations" message and then the screen goes blank. Now, let me give you a really detailed explanation of how I got to this point...... The PSP I bought had a TA-082 motherboard and firmware version 2.71. I was able to google instructions to get around this. I downloaded a downgrader specifically for the TA-082 and it worked fine (http://www.psp-hacks.com/file/983) on the second try. Then I upgraded to 3.10 OE-a (using http://www.sendspace.com/file/2mntd6) and things were working great. I ran into some problems when I uploaded certain files onto my memory stick... I was uploading stuff to the wrong directory and getting "corrupted data" errors and whatnot but I eventually figured things out. I was actually able to put a full copy of Vagrant Story on my memory stick and it was working beautifully. I was really psyched. I also downloaded a copy of Castlevania: SOTN and wanted to use it. It was a PSX rip and, according to what I read, I needed to upgrade to 3.10 OE-B so I set about doing that. Unfortunately, the directions I was able to find online were a bit hard to follow. I downloaded a file called PSP 1.5 to 3.02OE-B kit.rar. Inside the rar file there was a oeb.rar and a 302OE.rar and 302.pbp and 150.pbp. Inside the 302OE.rar there was a directory called OEB_UPDATE and a readme with these instructions: "Place the folder OEB_UPDATE inside /PSP/GAME150 and run it. The update will take a very little time, since it only updates the files needed." So I did that. But when I did, my PSP screen went black and it semi-bricked. The power LED stayed green and I couldnt turn it off by using the power switch. I had to take the battery out to turn the unit off entirely. When I tried to turn it on again, the LED would light up green but the unit wouldnt turn on. I thought I had bricked it completely but then I googled a bit and saw instructions to run the recovery console by holding R when turning the power on. I did this and it worked, I was able to get a recovery screen with the following options: Toggle USB Configuration -> Run program at /PSP/GAME/RECOVERY/EBOOT.PBP Advanced -> CPU Speed -> Plugins -> Registry hacks -> Exit I asked around a bit on some mIRC channels and people told me I needed to have the 1.50 downgrader in the /PSP/GAME/RECOVERY/ folder. After some experimentation I was able to get it right sort of. I have two files in that folder right now: EBOOT.PBP (63 KB) UPDATE.PBP (13.5 MB) And I choose the "Run program at /PSP/GAME/RECOVERY/EBOOT.PBP" option from the recovery console menu. At first, it gave me a message "Battery must be at least 75%" and turned off. So I left it to charge and tried it again a few hours later. Now, it gives me a message in small red text saying "Doing preparations" for about .8 seconds and then it flashes off and my screen goes black. The screen and unit are still on, but nothing else appears on my screen. So that's where I'm stuck... in the process of upgrading from 3.01 OE-A to 3.02 OE-B, my unit suddenly stopped powering on properly. I'm able to get to the recovery console without any trouble but when I try to run the 1.50 downgrader or whatever, it gives me the "Doing preparations" message and then the screen goes blank. Any ideas?
