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.

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.

2M. Check whether your serial number starts with
B4xxx. Mine didn't.)
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.
