[Important] MTRoW using Poly TC10 error "Failed to initialize SDK"

[SteffenBaierUK]

Hello all,

we have been made aware of an Issue with Microsoft Teams Rooms on Windows MTRoW in combination with Poly TC10 displays.

EDIT: A change has been made and no manual fix below is required if waiting for the next Maintenance Window overnight!

A current TCOS Software Update intended for MTRoA was also rolled out overnight to TCOS 6.7.0

As a fix Remote Desktop to the Poly Device

1. Open Windows Explorer and navigate to  C:\ProgramData\Poly\DFU\

• Open the file dfuAutomaticUpdateSettings with Notepad as and then close it again
  
  
  
• Press Windows Key and search for Notepad
  Right click on Notepad and run as Administrator
  
  
• Notepad opens again and has the dfuAutomaticSettings in the History
  
  
• Change the end time from 03:00 to 23:00
  
  
  

  Save the file and ensure it does not have an File Format .txt
  
  

  

• Reboot the MTRoW
  
  

• Once the MTRoW has rebooted leave it in an idle state without logging on as Administrator for 15-20 minutes
  

• After around 10 minutes or so TCOS 6.6.2 should download and Installed and downgrade the TC Device to TCOS 6.6.2 and pair with MTRoW
  
  

  

• There is no manual activity or anything, it just depends on the network bandwidth for a time perspective to download around 1,3 GB

  Once the file is downloaded the updater will replace the Files in the TC10 directory C:\ProgramData\Poly\DFU\TC10\touchctrl
  
  

  

   to reflect the TCOS 6.6.2 firmware
  
  

• The TC device will update
  
  
  
  

• Once the device has been downgraded to TCOS please modify the dfuAutomaticUpdateSettings again as an Administrator
  
  

  

  back from 23:00 to 03:00 
  
  

  
• And save this again and reboot
