I am running Ubuntu on my computer and I plugged in my tablet to flash TWRP to it. I enter
adb devices and here is the output:
juniorRubyist@juniorRubyist-iMac:~$ adb devices List of devices attached ???????????? no permissions ...
Why is it doing this. I have a Kindle Fire 1st Generation, it says that it will ask to authorize ADB, but it will not. It has ADB enabled (I think) and everything.
