problem in sigmatel s3
 

i have sigmatel s3 model.. it works without sim perfect but when we insert sim card.it will not power on i hav format with spiderman and write software in it ...but still handset is in same condition.......... plz post solution ...thanks

you need to do just formatt.
if u have read backup flash write it and just formatt after boot
when you click boot it shows formatt address
select that address in formatt option manualy

if u do not create backup before formatt and write find similar version from another working phone and flash it
