1. Buy a serial cable. They are cheap and the USB cable won't work for this 2. Download Bitpim (it's free) 3. connect your treo to your pc with the cable 4. Run bitpim 5. read the bitpim instructions. You are going to have to go through the supported phones until you find one that allows bitpim to read your phone. I am not at home so I can't tell you which one works. 6. When you get bitpim to work with the treo, look at the file system. Go to NVM, then NVM02 (or nvm002) 7. when you view the file (in hexdump) you'll see some stuff on the right of the screen, some that looks like garbage, some words like "Sprint". Look for a a sequence of numbers, 6 digits then a period, then six more, like xxxxxx.xxxxxx The second number is your MSL. That's the code you need. You can program your phone with it. If you have access to a program like QPST, you can change it to all 0's.
