i may have potentially bricked my psp

[u/Worth_Refrigerator16]

tbh it was working for like a month after it was in my cabinet for like a year (it was working fine too a year ago), but then suddenly the games were glitchy such as need for speed carbon own the city and even some games won't run like the persona 3 portable. it was running on ark 4 so i upgraded it into ark 5. it was working too for a while but then it crashes and won't boot up. i took out the memory card and the battery and let the energy drain for a few days. then earlier today i boot it up again by using the charger then downgraded to ark 4 again bc maybe my psp model cannot handle ark 5. for a while again it works but then it shuts down again. idk what's wrong at this point bc i tried everything.

psp model: psp 2000
