Re: Can't get serial connection in bootloader mode
Bootloader is different then Diag mode. Bootloader will not work.
If the ##3424 or ##3424# codes don't work for you, try going to the Windows directory, locate LaunchDMRouter, and tap it to start Diag. mode.
You must put the phone in Diagnostics mode, then:
Check your device manager to see which port the HTC modem is actually on.
Then go into QPST Configuration and add new port, select the one you just found it to be on in device manager.
Then you should be able to open QPST Service Programming and change your MSL.
If you need further assistance, let me know.
