Download and unzip the Nokia 2780 stock firmware with firehose programmer

Holding the Volume Up and Volume Down keys while plugging in or turning on the phone

Open QFIL

Select Flat Build

Click Load XML and select rawprogram0.xml then patch0.xml file in the stock firmware

Select Port (hopefully the phone shows up)
