I followed all the steps mentioned here and successfully flashed my first H801 and connected to smartthings! YAY!
Now I am trying to do this for 5 other H801 and I am stuck! As soon as I connect the jumper cables at J3, H801 dies. As soon as I remove J3 jumper cable, its working. This is killing me! I tried on 3 other H801 and the same thing is happening.
I am unable to figure out what is the issue
