1. Download the SU zip file from HERE.
2. Extract the contents from the SuperUser zip in a single folder on your desktop.
3. Go to the newly created folder and open the ‘system’ directory, then open ‘bin’ and copy the ‘SU’ file and paste it in the folder you’ll be working from. Then, open ‘system’ directory and then ‘app’ folder and copy the ‘SuperUser.apk’ file and paste it in the same folder as the ‘SU’ file.
4. Connect your Kindle Fire HD 7 tablet to your PC via the original USB cable. Open Settings app on your Kindle Fire HD 7 and then select ‘Security’ and now you need to enable the ‘adb’.
5. Go to the folder that contains the SU and the SuperUser apk files. Press and hold ‘shift’ key and at the same time right-click in the folder’s white space. Select ‘Open command window here’.
6. Now you will need to push the files by using the command lines below:
adb shell
rmdir /data/local/tmp
ln -s /data/ /data/local/tmp
exit
adb reboot
7. Your device will restart and the local temp file was removed and now you will have a false link to the whole data directory. After the device reboots you have to enter the following commands:
adb shell
echo ‘ro.kernel.quemu=1′ > /data/local.prop
exit
adb reboot
8. The Kindle Fire HD 7 will now reboot and you need to push the SU binary files. Enter the following commands:
adb shell mount -o remount,rw /system
adb push su /system/xbin/su
adb shell
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
rm /data/local.prop
exit
adb reboot
9. A new restart will be applied and now you can push the SuperUser apk file. Enter this final command line:
adb install Superuser.apk
10. That is it. You’ve finally flashed the root on your Amazon Kindle Fire HD 7 tablet.
If you didn’t manage to flash this tutorial, then you should ask for more help in comments.
