If you're getting an incorrect voltage error, it's a common issue w/ '02 WRX's that can be compensated for by powering one of the jumpers directly off the battery. I had to come up w/ a semi-elaborate means of routing power from the dash lights through a potmeter into the jumper to get my ECU to write.
There's a ton of info on NASIOC about the issue you and your friend that's doing the update should read.

I've made this work by jumping the jumper connector straight to the battery.
