k so rooting went easy peasy very nice link there Saguran

but changing or swapping out the rom not so well, good thing they made it idiot proof,
not feeling any more adventurous I decided to go with the latest stable release cm-10.1.2-i9100g I got from here
http://www.get.cm/?device=i9100g&type=stable
after I backed up and then wiped the data tried installing the CyanogenMod 10 ROM
gave me an error assert failed: getprop something something tried again and again
gapps installed easily I did this just to test the "theory"
Good lord had a heart attack when installing the backup up I made earlier, kept saying MD5 check sum error, tried multiple times still the same. decided to call on divine intervention (praying really hard) and the by the powers that be the phone is back to it normal self
not sure where I went wrong. maybe its the release I downloaded ?
while googleing the error msg I got this website

My one says something slightly different to the error msg this guy got but mostly the same, I am thinking of trying it out unless you guys got some expert advice.
I will wait for a reply before attempting it again my heart can't handle the stress
