As the title says, I'm wondering if there's a way to disable signature verification when I boot my Android phone into fastboot. I know that CWM and TWRP have an option to toggle it, but they aren't able to complete the job I'd like to accomplish. I'm trying to reflash the original stock ROM to my Moto G. I installed CyanogenMod but was dissatisfied with its instability at the moment. I then decided to return to the stock ROM and accidentally flashed the wrong region to my phone and I realized that I forgot to backup the original ROM... So now, as I try to flash the proper stock ROM I found on the Internet, I keep getting the "invalid piv signed system image" displaying on my phone. TL;DR - How do I disable signature verification in fastboot?
