Well then dont use it, there is no other root method for the s7 and there is no other fully working CWM for the s7.
Just pretend the s7 cant be rooted and has no custom rec, as noone else has stepped up to make a rooting method for the s7 (even though it's blindly easy to prepare)
If you cant get past the "Basic understanding of the command line" and arnt willing to learn, then that's your own fault.
NONE of the automatic rooting tools work and there's likely to not be any ANY TIME SOON, HC has been out for nearly a year and noone there have been no new exploits.
Using fastboot requires 2 things: having it downloaded, using the command line, the first is provided but you have to provide the 2nd part yourself.
There is literally no other steps beyond "fastboot flash <location of your recovery.img>" the only extra steps would be "remember to extract it" "remember to put them in the same place" "remember to use the keyboard to type commands" "remember the enter button is the enter button", and all this falls under BASIC COMMAND PROMPT KNOWLEDGE REQUIRED.
If you google "command prompt tutorial" there's 2 very long/good guides on learning the basics, but as you CLEARLY did not see the thread on installing CWM 5.0 right UNDERNEATH this one, are you in fact willing to take the 15 minutes or so learning how to use the command line?
There are also just as many guides to using fastboot in general if you type in "setting up fastboot" the only thing is that they dont contain the s7 specific drivers, and all these files are provided in fastboot+adb.zip, which is on the other thread that I have previously mentioned.
This is under the assumption that you are using windows, if you are using linux you should already know this and if you are using osx, I have yet to run into one that has a s7, they are actually on their own to a degree.
As for the SD card not working, great job on not reporting it to anyone, as DJ_Steve isnt active on this forum anymore and I'm the ONLY current active 'dev' (if you call this really simple stuff deving) you wont get any support as you clearly want to be handheld though the entire process. If someone had reported so that the sd card still wasnt working mabye I woulda investigated it, as it was in fact working after I had tested so and no other person reported it not working.
tl;dr: the device cant be rooted, there's no automagic way to do so.
PS. If I were a spiteful person I'd simply remove CWM and superuser7.zip entirely, as between me and DJ_Steve constutute 95% of the active devs that have released stuff for the s7 recently. Then the s7 would have absolutely no support at all on xda. Most of the devs should be able to root completely manually without any tools at all.
(not to discount you giveen, your work is currently even more behind the scenes then me, though i'd imagine if you were nudged and I didnt already make it you'd be able to replicate most of this stuff in a couple hours)
