yes its a tricky one this one
make sure you get the order correct
mine has been doing this for 2 years, and i got the order of things mixed up and lost my phone for 2 weeks whilst on hols with the bl**dy cr*ppy white screen.
today i fixed again by doing this:
take out batter
what the sh*t out of it on a table
punch it squarely in the centre too
Remove the SIM
Place battery back
turn on
i got the welcome screen again
then turn off, replace the sim and pray to buddha the next time u turn it on, it works.
Dont whack the phone if you can help it!
and if you do remove the batterry first, the small plastic hooks are very sh*t and break easily making the battery fall out and short the connections.
peace
