Hacked my PSP1000, question about my friend's PSP2000

[crash331]

I used a Pandora battery and a MMS to install 3.71 M33-4 and eerything is working perfectly. My coworkers want me to do the same to their system, but theirs is a PSP2000 bought in store about 3 weeks ago.

Should I have any concerns with this? I really don't want to brick their systems and then owe my coworkers money if they get pissed off. I am going to tell them it is at their own risk, but I still don't want to screw anything up.

Its cool, psp fats(1000's) are capable of using the batteries on slims.

I suggest you charge them though, co-workers/friends are the easiest to get money off of.

Atleast, I would. To my co-workers that is.
