So a few months back I had the idea to use a DSi battery in my AGS 101, however I accidentally bought a DSi XL battery, it would turn on and power fine but wouldn't come close to resting even if I had modified the shell. However I must have left the battery sitting and touching the connectors for a couple of days, no matter what battery I try, mainly the original GBA SP battery, it won't power on. If you plug the charger in and switch it on it'll flicker for a second and then stay turned off. You have to unplug and re-plug the charger in order to get this to happen again. I have no soldering experience but I'm wondering how on earth I can fix this. I modded the console myself with an original AGS 101 screen and although I've just bought another one recently I'd love to get this one working again properly.
