Will not instal OTA software update Plus MTP problem

Hi all

Just bought an unlocked Sprint S4
Two problems
The lollipop OTA update aborts with message: "/system/media/BST_bootsamsung.qmg" has unexpected contents.
E: Error in /cache/update.zip (status 7) Installation aborted.

Secondly when connecting the S4 to a PC I get message from PC saying: 'the last usb device you connected to this computer malfunctioned and windows does not recognise it'

I've installed kies no help there.

searched for remedies tried developer options etc on the phone all to no avail.
cannot get windows to recognise the phone as mtp device

when I plug it in I get no notifications on the phone
it does show its charging
running windows 10
