For correct operation device it is necessary to change CID SDcard on 035344535330344780399b1368010300.

This procedure is supported by not each SDcard.

Programs for change of CID and the description of process easy to find in the Internet.

I used mmc32 and evoplus_cid from github. This programs for linux. I haven’t found soft working in Windows

It is difficult to find SDcard which supports change CID.

SDcards with built-in chipset of production Samsung meet such requirements.

…or buy on Alibab, using search “CUSTOM CID”.
