The intialization from the SD Card was not the problem, i already managed to enter Vendor Mode, but i will send CMD26 write new CID....
How can i send CMD26 with new 16 bytes CID?

The first link references this: "...CSD and CID are sent to the host as 16 byte data block. For details of the CMD, CID and OCR, please refer to the MMC/SDC specs..."

How to do this with Arduino, i need an example how to send Cmd26 with argument and new Cid?
Can i do this only with sd.h und spi.h libraries, how to send the 16 bytes Cid in hex?
