Puck red light stays on after update/downgrade

Hi,

I received my puck about 3 days ago and starts playing with it, demos works great, (turn on led, read button, etc..), yesterday I notice that the firmware is version 1.92 so I updated the firmware to 1.94 per website using nfr connect/dfutarg, the update works (red becomes blue, then my phone states disconnecting after graph shows 100%, light becomes red again. I removed the battery wait a few seconds, reinsert battery now the red light stays on, check the website so maybe I touched the button, so removed and reinsert the battery again carefully not pressing or touching near the button, same result the red light stays on. So I downgrade to 1.92 and still the red light stays on. I could't connect to web ide, below is chrome console result. I also tried to hold the button while inserting the battery and I get green light, 3 led on, 5 red blink and when I tried to connect to web ide i get chrome console error (scroll down further on my post).
