I am trying up update my firmware to os_220. I have OS3.0 hardware and am or was connected via wifi. Per the firmware update guide, I downloaded the lastest firmware bin file (os_220_rev2.bin). in my browser I type http://192.168.0.111/update. I then selected the downloaded bin file, put in my password and hit submit. The screen says uploading please wait and has been that way for 20 minutes. How long does this process take? Does this mean the update has failed. Not sure what to do here. Thanks for any help you can give. If on the wrong thread please let me know where to go. I’ve been using open sprinkler for years but have never updated firmware or had any problems so I’m not real familiar with this forum.
One other note is that my LCD screen on the unit has been dead for years. The update process didn’t seem to require it so I went ahead.
