I recently became an owner of a PSP Slim 2003 after losing my beloved modded 1000. :(

As for the slim, its a 2003 model, date code 8A and its serial HB05xxxx
(bought after looking up the date code if it was hackable)

but its previous owner had no knowledge of CFW and just stuck OFW 6.37 on it before sending it to me.

I was wondering if I could get some help getting CFW on it, I've purchased a new datel tool battery from amazon but it doesn't seem to want to charge. I followed the instructions given but seems like nothing will get it to charge :(

I've looked up HEN etc but none of it will work.

Any help is appreciated!!
