I rooted my Infuse with InfuseRootUnlock v4 and it worked great for about a month. Went to turn it on & the phone starts normally but when the AT&T Logo screen comes on (after the Samsung swish screen) the phone vibrates 1x & then about 1.5 seconds later, its vibrates twice quickly & the screen stays black. It will do that until I turn it off or the battery dies. I've searched everywhere for a fix but only find the boot loop issues (which I did try but to no avail). Any advice will be greatly appreciated.
