I'm an older teenager that got interested in computers and computer repair after killing a computer at the age of 5. Since the age of 16 I've also been into game console/handheld repair, and I'm the one out of all my friends that is willing to open their system up to do basic maintenance.
Sony did that throughout the Dualshock 3’s production as they found out what would cause them to malfunction and fixed the issue. It should be alright as long as you are able to replace the battery when needed.
You broke the controller… I feel sick
What size are the screws? I’m trying to get a replacement set and it does me no good to not have a definite answer
