Ok here is the issue, I was trying to downgrade my psp from 1.5 to 1.0. with the MPH downgrader everything went fine until the downgrader told me to boot the psp. I booted and when i went to turn it on my psp still turned on but it frooze at the middle of the boot when the background starts to appear. It just stays there and turns off. This happens all the time with my psp, with or without a umd, with or without the MS. I took out the battery for a while put it on again and nothing. Now i dont know if the only solution is to buy the UP Modchip, or what. Please Heeeelp is needed.
Thanx in advance
