*#3646633# off my mobile and now it is just blinking

This means you have tweaked in misc setting......

Solution: You need to format your cell.There are two ways to format a cell:
  • You need a P.C. box to format & reinstall the O.S. of your mobile.(This option worked on my mobile)
  • The other is, fully recharge your battery & hold down end key for 1 minute 10 sec..This will format your cell.

Nokia PC suite will not work for sigmatel..
Sigmatel will work as a plug and play device like your pendrive

When you insert the data cable in the computers USB port the Phone would get a screen asking you to choose from 3 option
select the first option mass storage and then use you phone as a pendrive to move music files, videos and even snapshots....

i hope this helped otherwise pls post on any problem you face during these steps
