If the DFU is unsuccessful, the IPSW file extension or the firmware might be incompatible or damaged. You might want to download a new one but delete the old IPSW file extension first.
2. Test Hardware
If you have done DFU mode multiple times and iPhone error 1671 persists, it may be caused by a faulty hardware. The error usually occurs with a damaged mainboard due to long screw. Long screw damage root is when you accidentally use the long screw to a wrong screw hole causing the long screw to damage the mainboard.
The error may also occur when the iPhone has undergone a shock strong enough to damage the solder joint of the IC. The solder joint is the thing that connects the IC to the mainboard. If this is the case, please bring your iPhone to the Apple service center especially if it still has a warranty. If the warranty is void, you may want to bring it to a mobile phone repair shop to lessen the labor and part cost.
NOTE: Please be advised that opening an iPhone might void its warranty from the dealer if you accidentally remove the warranty seal or damage a part.
