I'm updating MC9300 running Android * Lifeguard 41.  The security bulletin of Android 10 is September 5,2020.  The current security bulletin is Oct 5th, 2021.  To update without a factory reset I'm attemping to use a UPL file.  

I'm using a data transfer rule, copying 4 files to the SDCARD folder.

HE_FULL_UPDATE_10-16-10.00-QG-U00-STD-HEL-04.ZIP

HE_DELTA_UPDATE_10-16-10.00-QG-U132-STD-HEL-04.ZIP

A10PlusLG132.UPL

Update_MC9300_A10_LG132.XML

The content of the UPL file is 

package:HE_FULL_UPDATE_10-16-10.00-QG-U00-STD-HEL-04.ZIP
package:HE_DELTA_UPDATE_10-16-10.00-QG-U132-STD-HEL-04.ZIP

I'm using a post install script to call the XML file

mxconfig /sdcard/Update_MC9300_A10_LG132.xml

This is the content of the XML file

<?xml version="1.0"?>

-<wap-provisioningdoc>

-<characteristic type="PowerMgr" version="8.1">

<parm value="10" name="ResetAction"/>

-<characteristic type="file-details">

<parm value="/sdcard/A10PlusLG132.upl" name="ZipFile"/>

</characteristic>

</characteristic>

</wap-provisioningdoc>

Nothing happens after the files sync and when I try to run the script manually it shows 

Custom log (Mxconfig - /sdcard/Update_MC9300_A10_LG132.xml processed success

And idea on what I'm doing wrong?
