yes, your SD card is wrong!
"Failed to enter vendor mode. Genuine Samsung Evo Plus?"

...so better luck next time. But if you are buying only for RNS 315 you don't need CID changeable card, you can use any card as long as you find anyone who is willing (and has the knowledge) to calculate pw from the CID. Contact user chelnov above..

Guys, as I cannot find anywhere laptop with proper sdcard reader I used android tablet to change the CID.
Im wondering if its possible to lock the sdcard on android?

EDIT: Never mind. I used my 2in1 Chuwi H10, was unsure of result because it showed mmcblk2, but it worked like a charm. Maps are already updated! Thanks.
