Nokia Nseries :: N8 Startup Failed Contact Retailer

ive had the Nokia n8 for a year and ive hated every single day of that year...... the nokia n8 is THE most problametic phone ive ever had.... and will be my last ever nokia phone. no matter what i do i get the nokia startup failed contact retailer. yes ive restarted my phone at least 100 times ...... yes i literally restarted my phone 100 times no exagaration.... my phone will start up like usual ..... then after a while it will give me the nokia n8 startup failed contact retailer is there any way to get this fixed without having to reset the whole phone to factory settings??.... ive been able to bypass the startup failed contact retailer by quickly quickly clicking on the small button on the left that then gives me the menu with all my applications but realisticly i shouldn't have to go through all the work to get my phone up...
