OK. So I watched the video obtained the firmware from the I2 firmware section. Installed the drivers on a Windows 10 x64 machine performing the steps for negating the driver signatures. Removed the drivers from Device Manager leaving the installed drivers on the PC. Fired up SP Flash Tool as Administrator, selected the Scatter File made sure download was showing. Removed the watch back disconnected the battery. Replaced the watch back. Hit download on the SP Flash Tool. Connected the Watch in it’s cradle to the PC via a USB cable. Unlike the example video there was no signs of the watch registering on the PC and the download starting.
I repeated all the steps again with another Windows 10 machine. Unfortunately I don’t have access to a Windows 7 or older machine.
Is there a way of confirming the drivers are healthy as if I connect one of my two functioning I2 watches it shows charger connected. Would it show the watch as a USB drive, is that how on other watches you copy Clock skins?
Whilst I wait a reply I will try and locate an older PC (not Windows 10) to repeat the test.
I am happy to do an online meeting with http://join.me if that would help diagnose the problem and use a webcam and screen share?
