[Q] Phone suddenly stopped working with 4.4 topic

Hi,

I was running AICP android 4.4 fine for weeks.

Then it kept hanging at boot screen , well just after when screen went black

Only way I could get to boot was clearing cache and re-boot. Worked OK then same thing any re-boot. This got worse and worse until nothing would boot.

I have found this isnt an ACIP issue all kitkat roms do this now on my phone (has now become they never boot). If I put 4.2.2 back on works perfectly

Im flashing the boot.img and reseting factory, dalvik and cache before flashing

Any ideas - really dont understand why 4.4 worked for a fortnight before becoming problematic and then being impossible to work
