i recently got a samsung g-600 from my friend, she had it unlocked as it was locked to orange and she had a vodafone sim. it worked fine for her and when i first got the phone it worked with my virgin sim. i turned the phone on again a few days ago, the phone goes through the setup of date, time and skin etc, the phone then resets itself over and over and the phone wont turn on?

ive tried different sims and none of them work they all do the above.
any ideas on how i can reset the phone or get it to work.


thanks for your time.
