E63 not starting

SOURCE: mobile startup failed . contact the retailer

hi,
Your phone's memory card must be infected with virus or has some fault. Please remove the memory card and try to start the phone again. If it goes through, please back up the data in your memory card and format it. In most cases, this procedure solves the "Phone start up failed. Contact the retailer" error.
I'd advice you to format your phones internal memory as well, it will flush out any errors present. save your "phonebook" data somewhere and Make sure your phone's battery is fully charged if not plug the charger in and proceed. NB: interrupting this process might render your phone useless. So, be careful.

To format press *#7370# it will prompt you for security code, enter it and the phone will reboot. Your phone will be reset to "factory settings."

Your phone need to be reflash but seeing that may cost you as much as a new 1112 so just buy a new one

It can also indicate you have messages on your SIM that are not yet copied to your phone.

Go to messages -> Options -> SIM Messages and delete or copy these messages and the blinking icon should dissapear.
