Can you root your Kindle without using a Kindle?
Your question is illogical. First, a regular Kindle does not
even run a version of Android so you can not root the device.
Second, how do you root a device you don't have without having the
the device. But, you can root a Kindle Fire which runs a custom
version of Android 2.3. Please specify you question, are you
talking about a regular Kindle or a Kindle Fire?
