Thingy flashing Red Color. Firmware not starting.

[gabi]

Got one new Thingy52 and worked all nice with both Android and iOS teminals.

Then I have tried to upload new firmware using the iOS. Loading new firmware progress was done at about 2.7KB and when completed the Thingy start flashing Red color regularly at 1 sec interval and with PWM like.

I have tried to Power it Off then while have the Button pressed to make device On. This changes the color into flashing Green and I can find the device if scanned for as a ThingyDfu. I have tried to repeat the firmware update :

• again it gets completed and the Thingy goes back to that Red flashing color mode.

Is there any way I can restore the firmware, please ?

Regards, Gabi.

Hi,

1. Can you confirm that you tried to upgrade from 1.0.0 FW to 1.1.0 FW?
2. What HW version do you have? 1.0.0?
