Hi, I have a similar problem to a couple of other posts in this forum. I can't find the SD card that came with the device when browsing within the RG350M - I put it into my computer and it shows fine. But nothing on the device itself.
Second weird thing - I try a new card that I already have, format it as FAT32 and if I try to boot the device up it won't boot up. It will only boot up with the original 16Gb card that came in the RG350M. If I swap cards after it boots then the newly formatted card also can't be found in the RG350M's file explorer.
