Windows 10 Mobile build 16212 (rs_iot) is an internal build of Windows 10 Mobile. It was unintentionally distributed to mobile users irrespective of their enrollment into the Windows Insider Program on 1 June 2017,[1] along with two other compiles from the rs_iot and rs_devices development branches.[2][3] Two separate desktop compiles from the rs_edge_case and rs2_release_svc_d branches were also unintentionally pushed out on the same day.[1]

It is one of the few known builds of Windows 10 Mobile to be based on the Windows 10 Fall Creators Update codebase.

Bugs[edit | edit source]

When it was released, this build worked only on HP Elite X3. After installation, other devices got stuck in a bootloop. The only workaround is to use the Windows Device Recovery Tool and re-flash.
