I went through each of the steps for upgrading the thingy91 modem firmware -> application firmware -> 52840 firmware but when I look at the lte link monitor it looks like the thingy91 just keeps re-booting. I am able to get the 9160dk working and i'm using the 10 pin debug port from the 9160dk to the thingy for programming. I don't understand what I'm doing wrong?
