Need some help/opinions.

Ok, I've tried many times to make a MMS, and I've failed every time(apparently). I don't know if I set up the MMS wrong or the battery is messed up. It's the model that works well(psp 110), and I hardmodded it to Pandora's. Ok, so I was thinking about ordering the tool battery, even though I got a Pandoras battery, is there anywhere to buy a MMS? And is it worth it to buy the tool battery?
My official firmware is 3.93.
I was also wondering if there is any way to get CFW without downgrading?

Use the auto installer link in my sig.

The only recent problems I've had with auto installers are that when they go for the mspformat, my computer fails at it. But I'm going to try it right now, hope it works. Also every time I try to get mms working, I put in the battery and MMS, but the power light is the only light that comes and and nothing ever happens.

You don't need mspformat for my installer.

Just format your MS on your PSP and put your PSP into "USB Mode"

Afterwards, Press and hold the up button as your PSP boots up.

Okay, well I did the program, but with pandora or with the normal battery, nothing happens. Did I forget to do something?
