A while ago I was fed up with Android Wear smartwatches and bought a Garmin Fenix 5 Plus. After using it for a while I started to explore the possibilities beyond the manufacturer specifications. This lead to a firmware patcher based upon work from Alex Whiter (who sadly passed in 2019). That patcher modified the firmware update file and disabled the license check for Garmin Maps. After installing a patched firmware, you were able to use any downloaded Garmin map on the watch without having to buy a license. Alex himself also offered a patcher to enable the use of custom made JNX "BirdsEye" files. (These JNX files can be easily created with SAS.Planet / SAS.Планета, a Windows tool to download map tiles and export them to different formats.)
These patchers sparked my interest in the firmware format as I've noticed they not only patched the few Bytes in the code but also modified other areas in the file.

2C (Comm signal analyser) which is a pure-software option. (In later production runs, the device might also already contain the necessary hardware for the bigger memory option
2M. Check whether your serial number starts with
B4xxx. Mine didn't.)
The original firmware in the HP 50g emulates a Saturn CPU
like the HP 48 and HP 49 had. However, the built-in ARM920T
processor has more power than the Saturn.

A few years ago, I got a Wansview NCH-536MW IP
camera. That was one of the first 720p cameras with night-vision, motion and
all features you could wish for.

Samsung seems to have failed, rushing to put out an update to the "Volume-"-bug in their Galaxy Nexus.
They provided a wrong-signed Google+ and Google Maps app. They failed to update ("Wrong package signature", see here).

To manually update the firmware, put the new firmware named as
