Thingy: 52 default firmware

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?

    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.
