Hi.
Some times this pin no need. U can cross data lines pins between themselfs.
Flash chip pins: 29,30,31,32    &    41,42,43,44
Try Google to translate this article:
Test MODE (VID/PID=0000)

Yes!, but u have not this pin! Try to join 29-30 memory chip pins => connect to USB => wait for detecting new device => then uncross 29-30pins => try AlcorMP util.

I think that the controller is patched with an error.
Please give mark the memory chips and controller, the number of memory chips. I will try to create a *. ini for use it in utility.
If it don`t helps, you will need to check a power at the controller pins by using the datasheet. There should be all the supply voltage! +5 V / +3.3 V / +1.8 V + / - 10%
Sorry for my "ruglish". )
