INNO_ERR Warning

INNO_ERR on Innosilicon: Firmware Recovery-Mode Symptom

D-Central taxonomy label for a reported Innosilicon fault or suspected failed-update state. No reviewed manufacturer source defines INNO_ERR as a specific recovery-mode diagnosis.

Warning — Should be addressed soon

Affected Models: Reported Innosilicon miner; exact affected-model scope is not established by the INNO_ERR label. Identify the full model, hashrate variant, control-board/platform and relevant PSU branch.

Quick answer

D-Central taxonomy label for a reported Innosilicon fault or suspected failed-update state. First step: Preserve the current state.

Symptoms

  • The token INNO_ERR or a recovery-mode description appears in a tool, interface, display, or log; preserve the full surrounding message.
  • The problem began after an update, configuration change, power interruption, or network interruption.
  • The miner has no IP address or web interface after one uninterrupted normal boot.
  • Ethernet link or a DHCP lease is present, but the normal interface is unavailable.
  • The controller is reachable but hashrate or one or more chains are missing.
  • The exact model, platform/control-board, PSU branch, or attempted package cannot yet be verified.

Step-by-Step Fix

1

Preserve the current state. Record where INNO_ERR appeared, the complete surrounding message, exact model label, visible state, attempted filename and what changed immediately before the fault.

2

Stop for smoke, abnormal heat, liquid exposure, damaged power hardware or failed cooling. Disconnect power if safe and request bench diagnosis.

3

Otherwise allow one uninterrupted normal boot after one controlled reboot. Verify stable power, a known-good Ethernet cable and a known-good switch or router port.

4

Check the router DHCP lease table and record whether the miner appears. A lease is an observation only; it does not identify the boot stage or prove firmware corruption.

5

Use the Innosilicon failed-update and no-IP recovery guide. Do not write another image until exact model, platform/control-board, source provenance and any required PSU branch are confirmed.

When to Seek Professional Repair

If the steps above do not resolve the issue, or if you are not comfortable performing these repairs yourself, professional service is recommended. Attempting advanced repairs without proper equipment can cause further damage.

Own your firmware — DCENT_OS (Antminer first)

DCENT_OS is D-Central’s open-source, GPL-3.0 firmware effort, publishing guarded experimental artifacts on Antminer (SHA-256) hardware — signed S9 and S19j Pro (Zynq/XIL) images are free to download. It is experimental and not production-ready. We build on the shoulders of the open-firmware projects that came before us, and we are starting with Antminer before widening hardware support. If you run Antminer gear, or just want firmware you can fully own and audit, inspect the exact evidence ledger before testing. This is a free public beta, never a pre-order — collection only, we will not email you anything else yet.
