New to CFW, issues with charging, Adrenaline and storage

So have my Vita 2000 modded now. The Vita games install no issues to the sd2vita. They seem to all run fine. When I try to install PSP games, my understanding is they are supposed to load to Adrenaline automatically. When I open it, there are no games. And its showing free storage from the sd2vita so i think i have it configured properly.

When plugged in with the Vita on, it charges for about 30 seconds and quits charging. Then see battery percentage drop while plugged in. Shouldn't it charge to 100% and also run off the charger? It charges just fine when turned off.

When i was setting up the sd2vita, the last step said to delete files off the vita itself, but when going into the vitashell, the uma0 and imc0 folders are no longer there that i can see. Not sure what im doing wrong.

Any advice much appreciated! Thanks
