It’s my understanding that firmware/bootware is needed in order for the sketches to work/run. I installed the Blink and the Blynk sketches and worked but they’re very unstable that’s when I started to look around for the latest firmware.

Well, you can always install the latest AT firmware, test the device, and then install whatever firmware / sketch you need.

It’s my understanding that firmware/bootware is needed in order for the sketches to work/run.

There is a bootloader, that is used to either boot your firmware/sketch or upload a new firmware/sketch; but it is fixed, and is not overwritten when you upload your own firmware/sketch.

I installed the Blink and the Blynk sketches and worked but they’re very unstable that’s when I started to look around for the latest firmware.

You can install back the latest AT firmware, or perhaps the latest NodeMCU firmware, and overwrite your blink firmware.
