Thingy: 52 default firmware

[Hammerschmidt]

I installed espruino_1v99_thingy52_app and espruino_1v99_thingy52_softdevice, but i want to restore the thingy to the default firmware. Have a way to reverse to the default configurations?

Take a look at the downloads on the Thingy product page ?

Yes, i tried with DFU, but don't work.

You could have mentioned that, then!

ISTR there's also non-DFU available?

See also the GitHub ?

I made the download with thingy:52 github FW, i used the nRF Toolbox connected with ThingyDFU and i made the upload and the app returns me a DFU FILE ERROR. And i don't know how to made a firmware replace without DFU.

Hi Daniel

Did you reset the Thingy with the button pressed to re-activate the bootloader?

If the DFU doesn't work the alternative is to flash the Thingy using the 10-pin J-Link connector on the side of the USB port (you need to remove the rubber casing to reveal it). 
You can use a standard nRF52/nRF52840 DK as a programmer, but the 10-pin cable must be purchased separately. 

Best regards
