    Also if the tool "said wrong chip" it means it is the wrong chip. Find the second 16MB chip and use the tool with the dump from that chip instead of posting requests one after another. This is your sixth or seventh request this week, are you going to open a Hewlett-Packard dealership there?

      Hi
      I'm looking at post 21 and 22
      where a member requested removal of password
      from 32MB chip like mine and one of your team
      removed it for him and it worked (post 24).
      Can you do the same for me?
      I had several that's why I made a good faith donation
      on the 24th.

          I resoldered the 32MB chip back onto the motherboard and then
          used RCunlocker on the 16MB dump but just got a solid CAP's lock LED.
          The motherboard went bad, a resistor near the 32MB chip broke off and
          could not be resoldered back on.
