Keyboard backlight not turning on Razer Blade Stealth 2016


I have a 2016 12.5" QHD. Everything was working fine and then I booted Kali linux off of usb stick and once I restarted the computer the backlight no longer worked at all. I've tried FN an F11, I've deleted and reinstalled the keyboard drivers, I've uninstalled and reinstalled razer synapse, NOTHING SEEMS TO WORK! If anyone has had a similar issue or knows how to solve this please let me know what worked for you.

Try wiping Synapse out of the system completely and then reinstall it back. To do this, just follow these steps:

1. Uninstall Razer Synapse from your PC and delete all files in C:\\Program Files (x86)\\Razer and C:\\ProgramData\\Razer directories. These folders may be hidden by default, so please be sure to unhide them. We want to ensure that there are no residual files remaining that may corrupt your installation. This is important so please do so. Restart your computer afterward.
2. Go into device manager, go to Keyboards/Audio inputs and outputs/Mouse and other pointing devices, uninstall HID Keyboard/Mouse Drivers and all other Razer product drivers, and restart your PC. Be sure to select delete drivers as well when uninstalling. Restart your computer again.
3. Turn off all Firewall and Anti-virus software to prevent any conflicts. Download and install the latest version of Microsoft .NET Framework (4.5 or higher) at http://www.microsoft.com/en-us/download/details.aspx?id=30653 (In some cases, you may need to uninstall the older version on your system). Restart your computer again.
4. Install the latest version of Razer Synapse that can be downloaded from http://rzr.to/synapse-pc-download (for Synapse 2) or http://rzr.to/synapse-3-pc-download (for Synapse 3).

You may test the unit again after this. Update me how it goes.

I used a program called Revo Uninstaller to delete razer synapse and chroma HDK from my system then manually checked through searching with the windows key for C:\\Program Files (x86)\\Razer and C:\\ProgramData\\Razer directories. I adjusted the settings to show hidden files as well then restarted my computer.
under device manager I went to HID devices and deleted Razer Blade stealth, HID-compliant touch screen, Synaptics HID Device, under keyboards I deleted HID Keyboard Device, and Razer Blade Stealth. Under Mice I deleed Razer Blade Stealth and Synaptics Touchpad. I was only able to uninstall most of the drivers, there were a couple that let me delete the data as well but I don't remember which ones let me do that. I then restarted my computer.
I wasn't able to unistall or reinstall the Microsoft .NET framework. I was able to go into the system settings and turn the .net framework off, reset my computer, then reset it again.

I reinstalled Razer Synapse2 and it still doesn't allow the keyboard to light up after I turn the .net framwork back on.

So, after this didn't work I pushed the windows key, typed security and did a fresh start. from https://support.razer.com/gaming-laptops/razer-blade-stealth/ I reinstalled all the drivers and updates for the security then reinstalled synapse and the keyboard still wont light up.
