The forum would only allow me to put one image in the post. So here’s the 2nd screenshot Carrier - still fails: ![](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/1X/86dcd2850d97d5c0567018a54b142b858d5ee3e0.png) ---

Everything looks ok for both firmware and carrier download based on the at data you show here. I’ll need to check on that version of module as to the response we get for carrier download. ---

OK - so it’s actually worked? Great! 😁 ---

FDT error code 4 means the tool failed to communicate with the module. The boot pin appeared to be used to start the update (not sure why). The boot pin must be de-asserted to allow the module to start-up properly. If the pin assertion was not removed in time for FDT to perform a sanity check after update, the error will be thrown. ---

So if I had flipped the switch at the point where it said “Resetting device …” it might all have worked without reporting any error? ---

It should have but you reported it didnt. Either way, you are good to go. Can you connect to a cell network? ---

But I wasn’t flipping the switch back; if it was in the instructions, I missed that bit. But, yes; it connects to the cell network - I have the SMS demo working. 😁 ---
