Good evening: There is no way to differentiate between the 7' and 8.9 inch tablet because they physically look the same.
You do have a 2012 tablet for which the SRT tools were designed for.
If you tablet is about the size of an 8-1/2 inch sheet of paper or (10" X 7"), you have an 8.9 inch tablet and the 8.1.4 tool is a good one.
If your tablet is smaller (about 6" X 8") then you have the 7" tablet and you need the 7.2.3 version of SRT.
None of the tool software will work unless, you can issue fastboot commands from your PC.
The SRT tool folder contains the fastboot executable so, in theory, if you move your command prompt to be in the same folder as fastboot.exe, you can use the tool.
Thus, you do not need more tools but, rather, you need to be able to use the SRT tool commands.
I indicated, you need to get the tablet into fastboot by issuing the command I listed at the command prompt where you have the fastboot.exe file located (In the SRT folder-wherever it is):
(with you tablet off and not connected to the PC
fastboot -i 0x1949 getvar product
The response will be "waiting for device"
If you see, "waiting for device", you are all set and can proceed.
If not, you need to get your command prompt window into the SRT folder where fastboot.exe is located.
Plug the tablet into the PC USB port.
Your tablet will boot up into fastboot.
You are then ready to use the SRT tool to restore to a working Kindle OS version.
Thus, the first step is to let us know if you can get your tablet into fastboot and whether you have a 7" or 8.9" tablet.
The above method only works on the 8.9. The 7" needs a special fastboot cable.
