Hello, I've followed the guide written by theascen and was successful up to the 8th step, unfortunately, when I try to transfer the nlaunch.tco to the nlaunch folder after deleting the current OS in the calculator I get an error saying that the OS file that I am trying to transfer is corrupted/not valid and nothing happens from here.
I don't know if this matters but currently my software is 3.1.0.392 and the factory number is P-........D
Any help would be greatly appreciated, as I've tried to do this multiple times already and always end up running into the same error.
