I’m currently fixing my friend’s Xbox One S which is stuck in a recovery loop and I’m getting E101/E106 errors during setup.

The original HDD failed, so I’ve replaced it with a known working 500GB drive. I’ve confirmed the drive is healthy and correctly partitioned (GPT clean installs tested as well).

The console always builds the partitions successfully (System Update / System Support etc.), but fails during OS install/validation.

Errors I’m getting:

  • E101 00000504 8B050041 (fails around 1–2%)
  • E106 00000009 80070002 (fails around 5–6% during reset)

Current system version it appears to expect:
26100.8064.xb_flt_2605ge (build 260429-2200)

I’ve tried:

  • Multiple HDD/SSD replacements
  • Diskpart clean + GPT
  • Fresh OSU1 USB (dated 15/04/2026)
  • Offline system update
  • Reset remove everything
  • Ethernet recovery attempt (no network activity detected)

In all cases, the process always fails during early install/validation stages.

Does anyone know if OSU1 is currently behind this build branch or if there’s a known fix for consoles on this xb_flt 26100 state?

Any help appreciated.
