User:Jevil7452/IUTool Error Codes

The most common errors in my experience are 0x80070032 (ERROR_NOT_SUPPORTED) and 0x80070490 (ERROR_NOT_FOUND). They usually arise whenever the user has a USB Flash Drive or MTP Device plugged in. The fix is to unplug them.

Another error I've received once is 0x80188257 (DUA_E_SESSION_TIMEDOUT). As I got it after the update had started, nothing actually failed, apart from IUTool reporting the error.

Below is a list of common error codes from https://github.com/Empyreal96/W10M-16212-Guides/wiki/Update-using-Phone-Updater:

  • 0x800b010a (CERT_E_CHAINING) - Signature Verification Error (enable flight signing)
  • 0x800b0101 (CERT_E_EXPIRED) - Incorrect Date and Time (change the date)
  • 0x80188306 - File Collision Detected or Files Not Found (use getdulogs and inspect ImgUpd.log for more details)
  • 0x802A0006 - try with another PC
  • 0x80004005 - Reboot the phone and try again. Still failed - try resetting the phone instead.

Microsoft's own documentation about IUTool errors can be found here: https://learn.microsoft.com/en-us/previous-versions/mt131833(v=vs.85)?redirectedfrom=MSDN (archived version: https://web.archive.org/web/20250309175214/https://learn.microsoft.com/en-us/previous-versions/mt131833(v=vs.85)?redirectedfrom=MSDN )

Whenever you receive an error, you need to run GetDULogs and check ImgUpd.log. Dealing with these errors is out of the scope for this page's contents.
