Flashing out is the final step, manual flashing can easily be done by using fast boot and ADB. The fash boot method is the proper way to downgrade your device. You need to download the fastboot tool from Google and then run it on your android.
Once you have the program, you need to run it and open the file explorer. Next, you have to save it to a location on the SDK installed on your device. You need to make sure that all the images you want to flash are in the same location as well.
