Google acc user info stuck

Hello everyone,

I am a little confused and frustrated, first let me state i am very new to phone modification and hacking. well in my case my lg eve was upped from 1.5-2.2 by a friend who is very computer savy also moddes his different phones like crazy. but when he modded my phone, he added his google acc information. after a while I tried to go back into the market and it says that there is a login error and i cannot get into the market because his info is used, we no longer speak so i cannot ask him for his password which i do not want to do anyway. is there a way to get rid of the acc info, i have tried various ways i.e factory reset(did not work) also it will not allow me to remove the acc under acc&settings. and ive spent the last 4-5 hours trying to setup the flashing utilities to no avail as it seems that my pc which is 32bit isnt supported in some way. does any one have any suggestions.
