Hi @banahaw
Have you installed all of the drivers from the driver pack download? It can be found here: https://techtablets.com/downloads-drivers-roms/
Focus on the drivers that aren’t marked Intel or Realtek, and you might have some luck.
I still have the default Windows install with 700MB recovery partition, but the problem is executing the recovery process. It’s done through the Windows Boot Manager and you won’t be able to launch it from the non-stock OS. Hopefully the drivers will do it for you.
