Screen will not stay on after downgrading... Thoughts?

[five40josh]

I had a 2.71 PSP with a TA-082 board. I upgraded to 2.80, then did the Hen 2.8/downgrader/1.50 Eboot install, and did the 2.80 ID Storage change for the TA-082 board, thanks to instructions by Kernel Kev in his tutorial. Everything went swimmingly- I made it to the blue screen at the end of the process and hit O, and I now have a 1.50 PSP. Only problem is the screen will not stay on now, it will flash on when I power up but flash off just as quickly. I know the PSP is still working, because I can hear it beep when I move around on the home screen. If I leave the psp alone for a few minutes, the screen will come on, but as soon as i press a button, then screen goes out. It seems as if the power conserving feature somehow got reversed!!

Did I do something wrong during the process? Has anyone else experienced this problem? Will upgrading resolve the issue? Thank you for your thoughts.

Anyone...?

Can I somehow revert back to my original firmware or something?

That seems very strange. Only things i can think of is that the downgrade somehow corrupt the video controller files or your screen has become loose at the same time (possible yet unlikely).

The only way i can think of sorting this is to upgrade (official or custom) and see if it continues. Only problem would be knowing what buttons to press.

I am a noob and decided to take a shot at going from ofw to cfw. I did hardmod a battery and created a magic ms. Since I have a slim battery, I just did the method of cutting a lead on the circuit board. Next, I downloaded the totalnewb. memory stick prog. I ran it and when I try to boot, I get nothing but a green light and blank screen...and no pressing X doesn't resolve my problem..(By the way I started with ofw v3.95). I then proceeded to d/l another newbie package to create a ms stick called Pandora -universal unbricker. I am now able boot to my ms stick, using the pandora battery. I go through the screen that says press X, and it finishes...Says press X again. I do that. PSP reboots to the PSP splash screen, then freezes for about 10 seconds, then shuts off automatically..What the hell!...After toying around, I decided to do the hold R button down thing, and power psp on. I now get a recovery menu for custom firmware mm3.71-2. I guided myself to the flash0 option and selected format. It did something and reboot. Now it reboot to what looked like a fresh psp xmb bar! yah...not really cause it went to something that resembles the BSOD on windows and says press O to format flash0 again. I push O and it shortly reboots again and started working again. I checked the system verison and low and behold it is on 3.71mm-2! I was able to proceed to update it to v4.01-2. How this worked, I have no idea but seems to be fine.
