Default [Q] XT926 RSDlite not recognizing device

So my razr is softbricked. I have been reading the forums here for the last 4 days, probably around 10 hours+ reading for solution. Anyways, my phone refuses to turn on and it pulls up the "downgraded security version" on the fastboot screen. Now, adb recognizes my phone in fastboot mode, and I tried flashing back the stock firmware (I had it updated to 9.30 locked bootloader) to no luck. I read that RSDlite is the way to go, but it refuses to recognize my phone. I have updated the drivers close to 9 times already, and I honestly doubt that's the issue, as adb can recognize my phone just fine. Under configuration/Flash Modes there's an option for fastboot, which is greyed out and unclick-able. Is there something I could do to get it to recognize my phone? I'm not ready to give up on it just yet.
