Zero Neck, thanks for setting this up! Got my N7 for Xmas and am now unlocked, rooted, and TWRP'ed! I read through the thread first and thought your directions were a bit odd (eg. "fastboot-mac")...once I unzipped the superboot folder, it appears it's simply a mini-sdk of sorts? If so, thanks for putting that together! It also raises another question - if we already have the Android SDK downloaded, we could have avoided that step, yes? I'm still learning how/when to use ADB, so I stuck to your instructions, but I'm thinking I could've done all this using my own SDK files and and tweaked the commands.
yeah for sure. if you already have adb/sdk you don't really need any of the files in the superboot folder (that's a paul o'brien creation - very simple package, easy to use). If you already have adb, you just unlock, dl and flash recovery, and install superuser/super su/or any rom that has root.
so if you already have adb/sdk, you just stick those files in the adb/sdk folder that contains fastboot (exe). so, for instance, you have a folder in your home directory called "adb", and "adb" contains a folder called "sdk tools" that has your fastboot exe in it. You stick the files you need in there (the recovery image, basically) and you put the su file in the virtual sd card on the tablet after you've unlocked the bootloader (bc the bootloader will erase the virtual sd when its unlocked).
so using that pretend set up, you would open up terminal on the mac and 'cd' to the folder that has fastboot, wherever it is.
ie:
cd home
cd adb
cd sdk tools
then you can do the commands as usual (usually, if you have a complete adb/sdk setup, "fastboot-mac.exe" is just "fastboot.exe").
so you would just:
./fastboot flash recovery xxxxxx.img
or what have you.
hope that helps. glad you got it done without any trouble.
