PowerShell version of Webpartmanager.Savechanges(????)

Question

Hi,
I am facing similar issue listed in 
http://sharepoint.stackexchange.com/questions/92619/paging-in-xsltlistviewwebpart-is-not-working-perfectly-when-added-programmatical
As per MSFT Forums, savechanges takes one parameter as input ie. Webpart
https://msdn.microsoft.com/EN-US/library/microsoft.sharepoint.webpartpages.splimitedwebpartmanager.savechanges(v=office.15).aspx
but when I try with I get exception 
'ERROR
An error occured during the placement of the AddListViewWebPart: Cannot convert argument "webPart", with value: "d0b13021-437a-49d2-a64d-a594af7f5ffa", for "SaveChanges" to
type "System.Web.UI.WebControls.WebParts.WebPart": "Cannot convert the "d0b13021-437a-49d2-a64d-a594af7f5ffa" value of type "System.Guid" to type "System.Web.UI.WebControls.WebParts.WebPart"."
which basically asking to give parameter of type 'System.Web.UI.WebControls.WebParts.WebPart"'
Also, when I try to pass object of type System.Web.UI.WebControls.WebParts.WebPart" - I get an exception
'object reference not set to instance of object' as listed in below URL.

Hi SGMSSharePoint,
I saw the thread in stackexchange that you mentioned had an anwser from the creator, maybe the creator was you.
The scirpt is:
function SaveChanges($siteUrl, $pageUrl,$viewName)
$web = Get-SPWeb $siteUrl
$publishingWeb =
[Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($web)
# Check if the page already exists
$currentPage = $publishingWeb.GetPublishingPages() | Where { $_.Url -eq $pageUrl}
CheckOutPage -spFile $currentPage.ListItem.File -allowUndoCheckout $false
$webPartProperty_Visible = $true
$web = get-spweb $siteUrl
$defaultPage = $web.GetFile($pageUrl)
# Get the LimitedWebPartManager
$webpartmanager = $defaultPage.GetLimitedWebPartManager([System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)
#Deleting existing web part
foreach ($webpart in ($webpartmanager.WebParts | Where-Object {$_.Title -eq $viewName}))
write-host $siteUrl +"Saving WebPart" + $webpart.Title + " : " + $webpart.ID
$webpartmanager.SaveChanges($webPart)
break;
CheckInPage -spFile $currentPage.ListItem.File
$web.Update();
$web.Dispose()
