Alright, I just installed cfm on my PSP-1000 (used off ebay) using the ChickHEN and HC Recovery Flasher method. So far, so good. Now the battery only lasts about 20 minutes when fully charged. My first thought was that the ebay guy gave me a defective battery (his posting said something to the effect of 'I can't guarantee battery life'). Then I did a little searching and found a bunch of people with the same problem (installed firmware, battery died), even if they buy a new battery it dies pretty quickly. People responded with 'something is wrong with your firmware' or 'you got your firmware from someone who is trying to brick your system'... referring to the fact that if the battery had run out while I was flashing the thing it would have bricked. edit: I updated to 5.00 as per Xist's advice from another topic. I don't know if it has any effect on the battery yet, but at least I'm not on the 3.71 anymore. 3. Is it possible older versions of hell cats recovery flasher has some problem where it pandorizes the battery, but doesn't 'un-pandorize' it? I know pandora batteries don't last very long, so that sounds plausible, though I doubt it. edit: I haven't messed with the clock speed controls, but I read somewhere that it might also be an issue.
