Recent Windows arm64 builds brick the device. The symptom is observed on at least Lumia 950, 950XL, NovaGo and Envy x2. While the ongoing investigation continues, it is a good idea to write-protect certain regions on the eMMC.

Protected regions

  • GPT header
  • SBL1 to TZAPPS, as well as PLAT

I would say write-protect sectors 0-253951
