I've been following the root instructions above. I'm at this step:
Using your custom recovery flash the download you chose above from Step 1 (#3)
However, I had forgotten to move the SU/Bootloader zip file to my SDCard (not a removable SD, the system SD). So I connected to my mac, used android file transfer to move the zip file to the SD card root directory (/sdcard/), and rebooted into recovery mode.
Now I'm in the samsung recovery mode (3e), with the little android fella and the red triangle, (manual mode), and if I select 'external storage', obviously since I don't have any (no removable SD), I can't seem to get to the file.
The first time I had rebooted into recovery I had gotten this screen:
But now I can't seem to get back to that screen to attempt to install the Super SU and Bootloader zip file.
Help?
