Success! Acer 5515 is activated. Thanks to all who helped. This was a little more complicated for me than prior activations. For some reason, the first time I renamed kaw6100_SLIC.WPH to kaw6100.WPH the flash process failed, but I retried and it worked the second time. Seems like I did everything seven times, but anyway it now works! Thanks to all who helped, and I appreciate the patience.
