ZTE - Unable to Bulk deregister devices

Hi Team,

Im having issues when trying to do a bulk device deregister. Getting an error message "Something went wrong - Try uploading your file again" and its not telling me what the issue is.

My current file format is .CSV and the table is as follow:

modemtype    modemid                   manufacturer    profiletype             owner
IMEI                   123456789012345    Motorola             ZERO_TOUCH       0

Can you tell me what I'm doing wrong? Thanks

Bulk deregister devices

Deregistering multiple devices in bulk can be done using a device configuration CSV file. To do this:

Create a device configuration CSV file including every device you wish to deregister.
Replace the 'profileid' column in this CSV file with a column titled 'owner', and set the values in this column to 0.
Re-upload the CSV to your portal.
