Hi, I've upgraded to the new firmware of NC200, two cameras are working ok, but the other two were blinking green light for hours. I've restarted one of the two cameras, and it now power on with a red light, no green or nothing, what should I do???

I send the update through Android, they are all connected through wifi, and the one who has the red light on is now with cable, but no luck (tried pushing the reset button for a minute with no luck)

When the camera is upgrading firmware, if network went out or power off, it will go die! The red light means the firmware has been damaged!

What's more, Tplink won't provide replacement for this as you have done wrong thing when upgrade, So, please note if the upgrade process has lasted a long time, just contact the support team, if they have no way to solve, at least they can provide replacement , am I right?:)
Also, I do suggest upgrading the firmware using Web-UI, for me it is safe and smooth.
