[Fire HD 8 and HD 10 General] :
Ok, I have tried again, with same results: SuperSU says there is no su binary installed. Here are the logs. The top log is more of each actual "human" step by step, and the bottom is the adb log. I gotta be missing something. Now, on my earlier attempts messing with it, I remember not issuing those "rm" commands and I went into superSU,and told it to update the binary and it took FOREVER, but eventually succeeded....I made sure it was sent to always grant, but root checkers/titanium backup would hang when verifying root, so despite that weird initial su updated that I got yesterday trying to get this going, I don't think it ever really did, and doing it via these order of steps I get that error. Any help appreciated.

so, right now, the tablet is at Step 10, with that error on the screen. I'll keep it right there, so you know where im at.

Thanks.
