yea if you know android well enough tha password is irrelevant, i cracked a galaxy s2 with no real trouble at all by flashing a custom recovery then using the adb connection to delete the file that stores the lock code. after that the pattern lock still appeared but would accept anything
all anyone has to do is.know what theyre doing and get an adb connection and its up for grabs, so if i were you id try to find a way to factory reset it first. get an adb connection in, erase everything in data, and cache, then youre good to go. any method of deletion will work and perform the same function as a factory reset through normal.methods
