Thingy:91 nRF9160 firmware 1.1.1 update

I had updated Thingy:91 nRF9160 firmware to 1.1.1 using nRF Desktop Programmer. I used the "Cellular Modem" button and attached the new file

However, after the update finished successfully and restarting the device,  the modem doesn't work, LEDs not working and all AT commands time outs.

Does that mean I broke the firmware, if so how to solve that?
