If you type "h" after step 15, you'll see a much bigger list of commands than normal - these are the ARM11 hidden commands.
If you boot into the ARM9 bootloader (hold VOLUP on powerup) with security-off, and type "h" you'll see a list of some of the ARM9 commands. There are actually more; it just doesn't list them in the help screen.
hello . can u please take some photos on HTC Multifunction Audio Cable YC A300 and the inside of it so i cnow what i need to do
does anbody else have this pinout screen or description? link is dead :/Hi KinkyGolab,
You can get the pinout details/pictures from my wiki http://www.suphammer.net/Hero/ExtUSB
Please note there is two PCB's in the dongle. I have only investigated the connections for the audio board (where the TTL serial signals are available).
Please use a TTL 3v level serial adapter when connecting to the serial pins. Connecting the serialport of your pc directly to the serial pins of the HTC will damage your HTC.
