I'm using 2 PSP's. Both have been successfully downgraded to 1.50 using pandora's battery. Now, when I run the m33 installer, it works on one of the PSP's. Using the same memory stick, I go to the other PSP, and I flash it. Upon rebooting, the orange light(MS LED) blinks fairly quickly. The backlight of the PSP is on, but it doesn't load.
