The US distributor said GPH won't replace it & he doesn't know how to fix it if it's that badly bricked. Last edited by a moderator: Feb 4, 2016

I have found this: http://www.bluewaternz.com/corporate/uni/unikit/jtag/ Can't read the scematics but the specs for this are kicking around the net. you could also buy a kit for some obscene ammount of $$$ (100s atleast). Basiacally JTAG is a sort of debugging and testing / recovery facility on CPUs and FLASH memory (and other devices). Don't know much beyond that. Someone here must have made their own JTAG cables'n stuff? (special software will be needed as well, along with a firmware image) speak up!
