Home button doesn't work, flickers, doesn't go home

[CandleStick69]

Like 2 weeks ago this problem first started, first it would go to the navigator app when I pressed the home button..
I force killed navigator and it fixed itself, sometimes it wouldnt work but most of the time when i pressed hom ei went home.
well today it hasn't been working at all, browsing sucks,

i have to press back like 40 times to get home.
i can't use my phone properly.
i tried a hard reset, formatted SD card

i have stock 2.1 hero downloaded the update today, but i had this problem likebefore the update but it wasn't as bad. if i could go back to the old verison like whatever was released today, the one before it that would be cool..

i just reset my phone andlost my settings and all. i was hoping the hard reset would work but it didnt. please help me.

i beg you. :/
