EDIT: Superseded by TSB 22-2150. Use the updated procedure.
Here's the official fix for all those stuck at Power-Up 1.7.1:
TECHNICAL SERVICE BULLETIN 22-2117 22 March 2022
Ford Power-Up Software Update Failure Message And/Or Unable To Update The APIM Or TCU With The FDRS And USB Drive - Module Recovery
Issue: Some 2021 Mustang Mach-E and F-150 customers may report experiencing a Ford Power-Up software update failure message via the vehicle display and/or FordPass. In addition, some technicians may experience the inability to update the accessory protocol interface module (APIM) or telematics control unit (TCU) using the Ford Diagnosis and Repair System (FDRS) and Universal Serial Bus (USB) drive. It may also be observed on the PTS - Over The Air (OTA) dashboard that multiple APIM and/or TCU updates have failed, or a no OTA history message is displayed. This may be due to a internal software error. To correct this condition, follow the Service Procedure to recover the APIM/TCU.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
See attached PDF for the full procedure. Your dealer will need the listed adapters and cables to perform the fix (see below). Remind them to update their FDRS software to the latest version before attempting, outdated software may cause the procedure to fail. The technician will need both the USB and the ethernet adapter ready to go depending on what the computer instructs during the procedure.
Access to the APIM USB cable behind the console side cover is required, it appears this is done to bypass the USB hub built into the port. The hub before the APIM may have caused technical difficulties during the original procedure, hence this TSB is the workaround.
Console side cover removal:
View from driver's footwell:
Remove the green cover, remove the bolt. Pull outward (3 clips to undo) then rearward on the panel to remove. Install in reverse.

Estimated completion time: 1-2 hours• 2021 F-150/Mustang Mach-E
• Ford Power-Up software update failure message via the vehicle display or FordPass
• Inability to update the APIM or TCU using the FDRS and USB drive
See attached PDF for the full procedure. Your dealer will need the listed adapters and cables to perform the fix (see below). Remind them to update their FDRS software to the latest version before attempting, outdated software may cause the procedure to fail. The technician will need both the USB and the ethernet adapter ready to go depending on what the computer instructs during the procedure.
NOTE: Figures are labeled immediately above, not below. I've fixed the pagination in the PDF so it makes more sense. Your dealer might be confused if they print it off the default way.TSB 22-2117 requires the use of commercially available adapters and cables to perform the APIM/TCU recovery procedure. Therefore it is recommended that dealers obtain these components in advance to prepare for the need to perform the TSB service procedure. The reference to use the following USB-to-Ethernet adapters isbased upon successful testing conducted by Ford: Trendnet TU2-ET100 USB2.0, Trendnet TU3-ETG USB 3.0 or Startech USB31000S USB 3.0. Refer to TSB 22-2117 for additional information.
