Sorry for offtopic, it's not a Garmin Map pilot project but I'm writing this here because it's also related to changing CID as I’m working on another similar project..
so...I'm trying to change CID:
Writing new CID: 5d53424c32424d31013917ca53010400
Success! Remove and reinsert SD card to check new CID.
but when I unmount and mount SD card again to check new CID, last 3 numbers aren't the same:
/usr/local/src/evoplus_cid/jni# sudo cat /sys/block/mmcblk0/device/cid
OS: Ubuntu 12.04.5 LTS (32 bit)
I'm using "famous" Evoplus 32 GB SD card. Any clues?
thanks for any feedback!
