Hi all... I was following step by step these instructions Instructions ------------ Here are the steps to downgrade any 3.50 PSP to 1.50: 1 - If you have a 3.50 PSP skip to step 6 2 - Download 3.50 update from here: http://dl.qj.net/PSP-Firmware-3.50-(North-America)-PSP/pg/12/fid/13840/catid/163 3 - Unzip and place the file in <pspdrive>:/PSP/GAME/UPDATE 4 - On the PSP, run the 3.50 update from the memory stick under the Game menu. 5 - Delete <pspdrive>:/PSP/GAME/UPDATE 6 - Copy the contents of the folder MS_ROOT from the 3.50 downgrader ZIP to the memory stick 7 - Unzip the 1.50 update to a temporary folder. Rename the EBOOT.PBP to UPDATE.PBP and copy it to <pspdrive>:/PSP/GAME/UPDATE/ . DO NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP! 8 - Load Lumines and press x to start the game 9 - The screen will clear to black and fill with a light blue colour, then the PSP will reset itself 10 - Check that HEN is running by going to system settings, then to "System Information" and it should show up as system version 350 HEN 11 - If it is showing up as HEN then go to the memory stick and run the x.yz update 12 - If you have an unpatched TA-082 or higher motherboard, you will be prompted to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it. 13 - Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing, if you no longer want to continue press the Right Shoulder Button (R-TRIGGER). 14 - Once you have agreed to start the downgrade do not unplug the PSP, or try and restart it 15 - Once finished the PSP will ask you to press X, and reset itself 16 - If it comes up saying that the settings are corrupt, press x to continue, this will mean you will need to re-enter the settings for network connections into your PSP, otherwise go to step 18 17 - Load the included NetConfigBackup application in your PSP, and select to restore, this will take the backup that was done of the network config that was done automatically during the downgrade. 18 - All done now Hopefully you now have a 1.50 PSP. Enjoy it responsibly. After step 15 I got a black screen with a pinkish text saying OK. I pressed X and then my screen went black... Apparently it was restarting itself... It started playing some music which I think is from Lumines but i'm not sure... After waiting a while I tried to restar the PSP bou no uck... I hear all the standard sounds and plin and etc but no image at all... Eventually when i hold the power button up i see a flash of a blue screen with lots of white txt. I have no idea what i've done wrong... any guess? Thanks!
