OTA update boot loop after factory reset existing root Kitkat

[Guest jcrump]

I should have read up before I factory reset my rooted hudl2.

After the factory reset it connects to WiFi then downloads an update and asks to restart. The update fails (status 7 failure then status 1). Rebooting takes me to the same downloading updates screen.

I think I was on Kitkat 4.2.2

In recovery if I access "apply update from ADB" then on the PC type adb-windows devices I see the following: 

\Desktop\Hudl2\adbfastboothudl>adb-windows devices
List of devices attached
151214PE5053407 sideload

Might that be a way to fix things?

Thanks in advance for your help.
