PSP's firmware might be the cause for Home button/XMB button not working properly?

Model: PSP-3006 (04g)

OFW: 6.61
CFW: 6.61 PRO-C

So long time ago I started to fiddle with my own PSP and upgraded its official firmware to 6.61 released by Sony official website (now it has been taken down and replaced with Sony's support page), then downloaded the 6.61 PRO-C custom firmware and installed it. After a certain period I noticed Home button doesn't work when I want to quit the game, so I assumed it might be caused by the degraded ribbon so I bought and replaced one by myself.
At first it works properly for a period, like over 3 months span but soon it fails to work again. So I ended up order another one and replaced on it.
But now without me disassembling and reassembling the Home button still doesn't work sometimes, it works somehow after I put it into hibernate mode and wake it up, completely turn off and on, uninstall CFW and install CFW once again, and even take out the battery and put it back again to boot it up.

I have never encountered such problem when I was using 6.60 OFW and 6.60 PRO-B2 CFW, and I've tried with several 6.61's CFW I could find from forum related to PSP modding, could it be the 6.61 OFW bug?

I dont think its a bug of any sort. Software wont break a button or a ribbon cable. Its either a user problem or a problem with your device somehow.

Sorry for the 6 days late reply.

So I determined it as "probably the software that causing XMB button doesn't work" is because, I have replaced 2 new ribbons before that and now I have the 3rd one in and hold the ribbon in place with a tape to make sure it is connected properly. But the XMB button still doesn't work properly sometimes.

Speaking of other possible hardware problem, I suspected that once I took out the battery, the system will ask me to set the time again rather than just restore the time itself. Not sure this could be the culprit.
