Yep. PCMHammer does contain a fair slab of the code from my ls1flash tool, and I have been working closely with NSFW developing it. The supplied kernel is a variant of my from ls1flash, with slightly modified timing to work around a timing issue we encountered with the allpro. Specifically its not listening and cant listen on the pcm side while its sending to the pc. So the 'About to send payload' closely followed by the payload fails unless the allpro has just a moment between messages to push the first short message to the pc. Any further discussion, please use the other thread.
