I’ve been meaning to upgrade for quite a while and finally got around too it but having trouble. I read this website: https://openthings.freshdesk.com/support/solutions/articles/5000381694-opensprinkler-firmware-update-guide and turned on the bootloader by holding b2 while inserting the usb. The device popped up on my device manager in Windows as opensprinkler 2.1. Then I opened the opensprinkler updater and it detected the device as 2.1 and I hit update device. Then it said downloading 2.1.7 and it never changed. 10 minutes later I gave up and closed the application. Then I tried the alternative updator and it said he couldn’t find the device. I tried to reboot the device and put it back into booterloader mode but it will no longer pop up in the device manager. I can power the device normally and it boots firmware 2.0.9 no problem.
So, my first question is: how do I resolve the problem with getting it back on boot loader mode so it will show up in my device manager?
I attached a picture in case that helps understand what hardware version it is since I don’t really know :). Edit: device has an Ethernet port.
I am not quite sure how the updater was trying to upload firmware 2.1.7 to the controller — since you have OS 2.1, the firmware updater disables firmware 2.1.6 and 2.1.7 for OS 2.1 because they cannot be uploaded through USB.
