i have problem i cant downgrade iphone 4g ios 5.1 to ios 4.1 i need full steps on how to do it if it possible

thanks in advance

Not possible unless you got shsh blobs for 4.1 saved on cydia (saurik)

i havent any saved shsh for any ver and really need to downgrade it it updated by a mistake any other ways ???????

Unfortunately NO!

Apple has stopped signing anything older than 5.0, you you will get error 3194 when trying to downgrade.
