Wyse Tx0 909566-10L DOVE_BOOT Firmware Needed

Anyone still have access to the last release of this firmware? The links for this in Dell Digital Locker for ThinOS Maintenance support are broken and Wyse Support from Dell has been completely unhelpful in resolving this.

The last release I see is 8.1_029, but frankly, anything newer than 7.x would be great.
