It's a safe rooting method. If your device isn't compatible, it will just tell you that when you try to run it. It is supposed to work on any device with a kernel build date prior to June 3, 2014. If you try that, let me know how it goes.
I'm not sure that there is even custom recovery available for your device, but you might also ask around in HERE to see if there is anything they can do for you. If they are willing to give it a try, they may need you to dump some memory blocks from the device so they can get the partition layout.
