After an unsucessful unlocking of my 166+ XP AROIA "Y" it seems I can't get it back to 10.5 default multiplier.I tried isopropanol alcohol and also Acetone to clean the L1 bridges.I used crazy glue for the pits and defogger repair kit for the contacts.I must have cleaned it about 2-3 times with the alcohol and a dozen times with acetone and no luck getting it back to default.There is copper showing between the 3rd and 4th dots in a vertical line but not touching each other.I was wondering if this might be my problem even though they don't touch.Any help out there on what I could try?.
