Flash magic uses... 3pulse on reset method with the command and programming data sent to the RxD / TxD UART pins of the micro.
The UART requires a stable/reliable Osc...
If you have reconfigured the Oscillator configuration non-volatile selection then you should get the micro oscillator operating in this mode, as the UART is Dependant on oscillation from the selected - reliable source.
So that may mean putting a Xtal or Osc and Osc-caps on Xtal1 Xtal2 pins of the micro to get it oscillating in the correct mode, programming the part and selecting the correct Osc input.
===> Otherwise the brute force method is to use ICP which programs the micro at a lower hardware level where the Osc is not required.
