Manual method installation

Manual installation method

Introduction
Here I will explain how to install the firmware using a command window or any other terminal.

The requirements are the ones stated in first post.

On your terminal, go to the path where all the files were unzipped, or if you are running a Windows OS, just run terminal_cmd.bat and you are good to go.

How to Unbrick your watch
If your device is bricked, stuck at initial Amazfit logo, and no adb connection with PC, you have to reboot your watch into fastboot mode using the button and USB plug trick with this tutorial, and then you can run UNBRICK_US.bat to the root of the stock Firmware folder with all the other files, and run it.

Or you can install the firmware using manual commands and starting at Point 3.

OTA Installation
Download OTA installer from Post #1 and if you are running a Windows PC, run terminal_cmd.bat, or any other command/terminal window on your PC in the root of the unzipped folder.
Copy the update to the watch
Code:
[COLOR="Blue"]adb push update.zip /sdcard
[/COLOR]
And launch the update
Code:
[COLOR="blue"]adb reboot update[/COLOR]
Wait to the end of the update, and when the watch reboots delete the update file
Code:
[COLOR="blue"]adb shell rm /sdcard/update.zip[/COLOR]

Firmware installation
On your terminal, go to the path where all the Firmware files were unzipped.

You can copy and paste all needed commands.

1. Connect the watch to the PC and check the connection with the watch
Code:
[COLOR="Blue"]adb devices[/COLOR]
