DaFlasherFiles
These are the files needed for the DaFlasher app, Playstore: https://play.google.com/store/apps/details?id=com.atcnetz.paatc.patc
After flashing you will end with an Nordic DFU Bootloader where you can flash your own Firmware to The Watch. Like via Arduino etc.
You can support my work via paypal: https://paypal.me/hoverboard1 this keeps projects like this comming.
And all without opening the watch, all over the Air.
I recomment to have one opened watch to develope new Firmware and when it is tested upload it to the closed Watch
Here you have the 3 Files you can see me using in this video:

You can Upate the Bootloader and SD to any Other version as long as the New Bootloader is At address 0x78000,
this can also be changed but needs an additional bootloader and flash step.
Files:
DaFitBootloader_nRF52840_Hacked.bin
This directly enables an SD 6.1.1 Nordic compatible Secure DFU on DaFit nRF52840 Watches like Kospet Rock or Magic 3 It accepts any signing key to not lock yourself out of the watch, but you still have to suply a signing file when generating an DFU update. No aditional file needs to be flashed.
DaFitBootloader23Hacked.bin
This gets you started, flash this file first when you are on the Stock DaFit Firmware, this will install an Custom Bootloader i made using the Installed SoftDevice5.0.1 Here is a list of all the Compatible watches that can be flashed with this "Hack" https://gist.github.com/atc1441/d0a3c1f5ee69ab901bccba4eb47a6e4e
FitBootloaderDFU2.0.1.zip
This installs the SoftDevice version 2.0.1 and an Bootloader for SD2.0.1 useable when on SD5.0.1
To create your own DFU update files for SD2.0.1 you need to use nrfutilV0.5.3:

ATCdfuFromSD2toSD5.zip
If you want to go Back to SD5.0.0 Bootloader you can do so with this file
ATCwatchP8.ino.zip // OLD Name: P8TestMenuDisplay.ino.zip
This is just a more advanced demo Made for the P8 Smartwatch to show the hardware is working, it will also run on other Watches but maybe they have different pinout for aditional Hardware like the Push Button.
ATCwatchPineTime.ino.zip // OLD Name: PineTimeTestMenuDisplay.ino.zip
This is just a more advanced demo Made for the PineTime Smartwatch to show the hardware is working, it will also run on other Watches but maybe they have different pinout for aditional Hardware like the Push Button.
