how to run sfc with offlogfile flag

Ran SFC , Got the following.

"C:\WINDOWS\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag."

Background is that the tablet's wifi and bluetooth aren't working, That means I can't run DISM or repair online.

I have an identical tablet with the same drivers. That is working no problem. I have also uninstalled the drivers and restarted to reinstall them. Also done a reinstall of 1809. sfc is still showing corrupt files. Problem came from failed 1903 update and rollback to 1809.

I am trying to see if the sfc logfile will help me repair.

I have already tried sfc /scannow /offlogfile=c;\scanlog.txt
and sfc /offlogfile=c:\scanlog.txt

If needed consider running DISM limit access commands.
First check the CBS log file to find the underlying problem(s).

Administrative command prompt:
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >%userprofile%\Desktop\sfcdetails.txt

Look for a new text file on the desktop > post a share link into the thread using one drive, drop box, or google drive

C:\Windows\Logs\CBS\CBS.log
C:\Windows\Logs\Dism\Dism.log



Use DISM to Repair Windows 10 Image

/offlogfile is for when you run sfc /scannow in offline mode, ie from say a winpe, win re, recovery drive or install media usb...

SFC /scannow /offbootdir=C:\ /offwindir=C:\windows /offlogfile:C:\scanlog.txt

this assumes that C: is your system drive ...sometimes the drive letter will change so use:

wmic logicaldisk get deviceid, volumename, description to list your volume drive letters to select the correct drive letter

Thanks, Denis. It was the same list actually. However I am struggling to accept that it is hardware.

Wifi was working for the update but wasn't working after the rollback following the failure of the update.

I managed to get bluetooth going by reinstalling the driver but it is jittery or spasmodic at best.

I did another reinstall with the source obtained from an identical tablet that works. Now they have identical drivers, Windows versions and hardware. Still not working. Makes no sense.
