Well I was looking into my walkman's service menu to do the ATRAC Type R hack along with the R900 Features hack while learning how it works by looking in the service manual, but I messed up some things so I panicked and then decided to do a 021 Reset NV... Now it just sits at the service menu blink, according to the manual I need to do the electrical adjustments, but all I have is MO type MD's and no CD type MDs... so I cant do all of the adjustments... Can anyone help me? I've tried http:
