I dropped Rom and Gapps into root folder of S3 GT-I9300. The Resurrection Remix rom update and Gapps will not show in SD card folder when I try to flash using TWRP. I did the other S3 update ok, so can't understand why this one is being iffy.. Sd card is mounted ok- that can be seen in Storage and USB folder. Any ideas please?? When I updated the first S3, say S3A, the backup, rom flash and Gapps flash went great, but as I was messing with the other S3, I was supposed to have wiped cache and Dalvik cache, but phone just carried on happily by itself and started optimizing apps. All seems to be ok with that one. Any harm done ?
