My Tab S is wiped clean, has no firmware, except TWRP. I am trying to use an SD Card to install ROMs from it. I am formatting the SD Card in Windows 7, copy the necessary zip files into it, insert it into the Tab S, reboot into recovery. I have tried FAT32 and exFAT. No matter which format type I try, TWRP does not see" the SD Card. Can someone please tell me what's happening and how I can get TWRP to "see" my SD Card? PS I have tried 3 different SD Cards to make sure.
