[Q] Rescue Killed Shield Tablet K1

i'm trying to rescue my killed Shield K1.
we know that the tablet is still in APX-Mode and there is the possibilty sending commands with nvflash.
what we need is the cpuid or uid which is to get with a special script (thx Moscow Desire). in many cases was people able to find out the "cpuid" and obtain the SKB
. eg. hier with iconia a500 : http://ift.tt/1Z92Akd
i also tried to get the SBK from my K1 with a modificated script(changed the "vid_pid to 0x0955, 0x7F40" and "received_length" to 16) but without success. i got a wrong uid (just last seven digits was true the first eight digits was ziros) and thus a wrong SBK.

if we get the right uid we can be able to use nvflash.
hier is some questions:
how many digits are the right cpuid from K1?
can someone make a script for our purpose?
thanks for your help.
regards
Cappy
