possible to root Amazon Fire HD 10 5th gen running Fire OS 22.214.171.124?
I've come across this device and figure it'd make a very nice information display. But after searching this forum and reading tons of posts I am uncertain whether or not it's possible to root this device, root this OS version, or (if needed in order to root) downgrade this OS version. Most success stories here appear to refer to the Fire HD 7 5th gen, I think.
I've disabled wifi on the device so that it can't install any more system updates. Has anyone tried KingRoot with this one? Their support list doesn't mention Amazon devices. I suppose I could just try it and hope nothing gets bricked. I'm happy to try other methods if they'll work.
Looking for Testers for a Possible Root method
Using the same method of creating a Boot.img that makes the /system rw for the 2015 7 in Fire. @csolanol and @diegocr have created a batch file, with a modified boot.img for the HD 8/10.
There is some risk that this method will not work, Amazon may have done something different in the 8 and 10 models.
If the boot.img does not work, the tester may have to re install the firmware via adb sideload, or this could brick the device, although that is unlikely.
just post in this thread, if you are willing to test, the batch file is already uploaded to dropbox.
