[rach1984]

I recenlty had to make a claim on my insurance so got a replacement handset which is obviously a refurb. Not sure if that is relevent to the problem im having though?

I fully charged my phone while it was switched off as i always do at night and when turning it on this morning i just keep getting 'unexpected error' notification with please help us.... If i click on it my screen flashes off and on with a no apps showing at all just the background and if i clear it it does the same?????

If i lock the ohone it stops but i cant access anything??? Help!

Are you rooted?

If so, you could try wiping cache+dalvik and fixing permissions in CWM recovery.
(I'm unsure if these options are available in the standard Nandroid recovery)
