[HELP] Wiped everything and now I can't even flash FTF firmware

[:No-Frost:]

OK, here's my problem.

I've decided to perform a clean install but by mistake deleted everything so now I don't have a system to boot to (loose my recovery in the process)

Thing is that I'm trying to flash an FTF file using flashtool, but I get the following message:

05/005/2015 17:05:04 - ERROR - Drivers need to be installed for connected device.
05/005/2015 17:05:04 - ERROR - You can find them in the drivers folder of Flashtool.

Now, I'm trying to install the drivers, but then again, I get an error when installing:

Sony (WinUSB) sa0111AdbDeviceClass (04/15/2014 2.0.0010.30024) (this one installs fine)
Sony Net (05/05/2014 6.0.6000.16509) <------------- This one fails.


Any idea??

Thanks in advance.

ok, now you open prompt command with administrator permission and write this: bcdedit -set TESTSIGNING ON. Restart and try to reinstall driver
