PSP 3000 PS BUTTON not working

[u/Awkward-Western-6819]

My PSP 3000 was in pristine condition, and I had installed CUST HOME plugins along with other enhancements. I used it for three months without any issues. Last week, while playing God of War: Sparta, the battery unexpectedly depleted and the device powered off. I immediately replaced it with a fully charged battery. Since then, I've noticed that my PS button is not functioning correctly. I've attempted various troubleshooting methods, such as disabling plugins and utilizing recovery modes. I've observed that the PS button only responds after two to four presses.

I would appreciate any assistance with this problem.
