There's never a guarantee that a problem won't develop. As repeated over and once, removing the -w prevents the script from wiping the device. It works fine for me and others. Just make sure to use a good USB A to USB C cable.If I remove this line fastboot -w in the .bat file, will it work fine and not wipe my phone or cause any issue? But just technically update my phone. I don't keep up to date with Essential as it's my backup phone but will like to get it up to date now as I'm using it soon for a trip.
