Hello guys, I'm new to IDA and I need some help.

So I'm trying to make a product free of charge but I don't know which code to change here.

Do I change MOV R1, # to MOV R0, #1 in order to make it TRUE?
Highlighting MOV R1, # gives me a long hex (49 52 04 31 C0 F2 50 01), and since the hex for MOV R0, #1 is 01 20, changing the first 4 characters to 01 20 just causes the app to crash. Highlighting the other MOV R1 # code beneath gives a different hex that is (46 F2 9C 31 C0 F2 50 01). And I'm sure the binary is 2 byte since highlighting BX LR only gives 70 47.
