Creality Ender 3 Pro + BLTouch v3 1 + Marlin by Jethro

This certainly happened to me when I changed my previous hotend for a new all-metal one. The difference in sizes created an offset of about 14mm that needed to be accounted for. Double check in the Info menu that the expected firmware version is shown.

Some internet-connected devices regularly check for new firmware and automatically download and install it. Other device manufacturers require the user to visit the manufacturer’s website to download and install firmware updates manually. As technology advanced more rapidly, firmware started becoming outdated sooner, before the hardware got worn down.

Ideally also delete cache for before you attempt a new download. Programs that create HEX records typically use line termination characters that conform to the conventions of their operating systems. For example, Linux programs use a single LF (line feed, hex value 0A) character to terminate lines, whereas Windows programs use a CR (carriage return, hex value 0D) followed by a LF. These examples show the process of creating a Universal Hex. A V1 and V2 hex can be combined to produce a Universal Hex. If you can only support a V2 board, the standalone error can be combined with a V2 hex to produce a hex that will fail with an error on a V1 board, rather than failing silently.

Low-level firmware is typically stored in non-volatile read-only memory chips such as ROM. This means you cannot overwrite or update low-level firmware, which means that low-level firmware is an intrinsic part of the hardware. A device that contains low-level firmware has one-time programmable memory. Hardware manufacturers can use embedded firmware to control multiple hardware systems and devices. The idea is similar to how your operating system pushes updates to the software on your device. The difference here is that firmware installation takes place upon manufacturing the piece of hardware.
