small number of
discoloration dots, as so-called "non-conforming pixels." This phenomenon is a limitation of TFT LCD

Longines’s Flash Tool SOP
This document will give the sop of Longines’s Flash Tool. It includes two parts-the open of flash tool and
the download of a version.

After decompress the flash tool archive, the flash_tool.exe shows in Figure1 is the tool that we need.
Figure 1 The location of flash_tool.exe
Double check the flash_tool.exe, Figure 2 will show up, and after the “ok” button is clicked, we will
enter the download interface (Figure 3). The download of Fossil HD’s versions will be operated in this
interface. By now, we can start to use the flash tool.

Figure 3 The download interface of flash tool

14
Figure 4 The format interface of flash tool (forbidden)
As shown in Figure 4, the “Format” interface is forbidden to use. We just need to use the “Download”
interface shown in Figure3.
2. Download a Fossil HD’s whole version
It includes three steps shown in Figure 5, Figure 6 and Figure 7.
Step 1 and Step 2: click the “Scatter-loading” button to find MT8127_Android_scatter.txt, and then click
the “open” button to open the txt file. The file exists in the same folder that contains the image folder.
