Innosilicon Firmware Downloads: Exact-Model Source & Provenance Guide

Do not download or write an Innosilicon image until the full model, hashrate variant, control-board branch and, where applicable, PSU branch match the source record. This guide helps you interpret the original publisher’s download centre. It does not rehost unknown files or treat a nearby model as compatible.

Manufacturer legacy-catalog inventory

The manufacturer’s English legacy miner support centre still exposes a model selector for the T-series entries below. Many records are separated into G19 and SOC branches. Its footer is dated 2020, and it should not be described as an actively maintained current-download service.

Last checked: August 27, 2026. Every T-series firmware anchor remained empty or displayed NULL after the page finished loading, and the tested firmware-data endpoint returned 404. The linked Q&A’s tested direct package, batch-tool and manual endpoints also returned 404. No official firmware binary was validated as currently downloadable in this review.

Models currently represented in the original publisher’s English download selector
Family	Exact selector entries	Source interpretation	Required action
T3 family	T3s; T3+ Pro (G19/SOC); T3+ (G19/SOC); T3h / T3H+ (SOC); T3-43T	Historical manufacturer model records located; current artifacts empty.	Match exact suffix, hashrate and named branch. Do not infer a file exists.
T2Th family	T2Th+ (G19/SOC); T2Thf+; T2Thl+; T2Th; T2Thm; T2Thf (G19/SOC)	Historical manufacturer records located; current artifacts empty. “Unlabelled” entries are not proven branch-independent.	Do not collapse h, hf, hl, hm or plus variants into one package.
T2T variants	T2Tz-30T (SOC); T2T+(32T), T2Ts-26T, T2Ti-25T, T2T-24T and T2 (each G19/SOC)	Historical manufacturer records located; current artifacts empty. Some routes had platform or PSU-dependent conditions.	Resolve exact suffix, board/platform and PSU branch before seeking an archived artifact.
T1	T1 (G19)	Historical manufacturer model record located; current artifact empty.	Do not substitute a later T-series image.
Other models	Any model not shown above	No current exact public source established by this review.	Do not substitute a T-series neighbour; identify and escalate.

No verified public source is not permission to cross-flash. An unavailable file should route to identification or service, not a similarly named image.

How to read a firmware source record

1. Exact hardware scope

Match the complete model string and hashrate variant, then confirm the control-board or platform branch. A shared T2 or T3 prefix does not establish compatibility.

2. Original publisher

Prefer the manufacturer or original firmware publisher. A forum, chat attachment or anonymous mirror is not validated by a plausible filename.

3. Artifact identity

Record the complete filename, displayed version or release date, source URL and any hash published by the source. Preserve this evidence before the page changes.

4. Integrity versus suitability

A matching hash can show that a file matches a publisher’s record. It does not by itself prove the file is correct for your board, safe, current, endorsed or performant.

5. Availability status

A model can remain listed while its download field is empty. Treat a manual or historical listing as documentation, not as an implied binary download.

6. Recovery purpose

Normal web updates and model-specific recovery media are different paths. There is no universal T-series SD or TF image.

Platform and PSU branches are hard compatibility boundaries

The original catalogue frequently separates G19 and SOC records. Select the branch from evidence on the unit or its existing interface—not from appearance, family name or guesswork.

T2Tz and related publisher cautions

Some official T2Tz/T2Ts update routes depend on PSU manufacturer or version. Publisher guidance distinguishes direct routes for some QB/HK configurations and different paths for GP versions below or above 12.66. The exact boundary value 12.66 is not resolved by the evidence reviewed here, so escalate it rather than guessing. One affected GP route also specifies a 15-minute window with no operation and no interruption to power or network.

The publisher also warns on a T2Tz-30T record that a hashrate-oriented firmware change may require a PSU upgrade and that failing to make a required PSU change can harm the miner. This is a model-specific warning, not a universal T-series rule.

These conditions are why this page links to a live original source instead of turning changing records into permanent direct-download buttons.

Package evidence: what is known and what is not

An inspected authentic stock T2Tz build used a signed SWUpdate .swu container with a signed description and an A/B storage layout. That is evidence about the inspected T2Tz build only. It does not establish the package format for every Innosilicon model, and A/B slots do not prove automatic rollback.

Do not rename, unpack, modify or convert a package unless the exact publisher procedure explicitly requires it. Never use a package merely because an interface accepts the upload.

Before writing any package

Provenance: original source and complete source record preserved.
Identity: exact model, hashrate, platform/control-board and relevant PSU branch confirmed.
Purpose: normal update versus model-specific recovery route confirmed.
Continuity: stable power and network for the full publisher-specified window.
Exit plan: documented recovery path or bench-service plan identified before changing a working unit.

Stop for electrical smell, abnormal heat, liquid exposure, damaged power hardware, failed cooling, an identity mismatch, an unknown source, or a repeated failed write.

Choose the correct next path

Choose the overall firmware pathUse the hub for model, stock, custom, recovery and repair routing.
Check custom-firmware compatibilityUse confirmed model evidence before evaluating replacement firmware.
Triage a failed updateUse symptom-first recovery for no IP, no link or lost hashrate.
Read the wider provenance policyUnderstand original channels, archives, mirrors and integrity records.
Find operating documentationConfirm model-specific preparation and normal update requirements.
Request identification or repairSend the label, board, PSU, installed version, filename and failure timeline—never passwords or private access details.

Innosilicon firmware download questions

How do I identify the right Innosilicon firmware package?

Match the full chassis model and hashrate variant, the control-board or platform branch, and any applicable PSU branch. Then preserve the original publisher URL, filename, version or date and published hash as one source record.

Why is the model name alone not enough?

Nearby model names can hide different control boards, platform branches, boot chains, package formats or PSU requirements. Exact current hardware evidence is required.

Can I use firmware from a similar T-series model?

No compatibility should be inferred from a similar name. If the exact model and branch are not documented for that package, do not write it.

Does an old package listing mean the file is still safe to use?

No. A historical listing establishes context, not current availability or suitability. Re-check the original source, exact scope, version and integrity record at the time of use.

What should I do if no exact public source is available?

Do not substitute a nearby image or an unverified mirror. Preserve the unit’s labels and current evidence, then request model identification or repair support.

Should I download another image after a failed update?

Not until recovery triage establishes the symptom, exact hardware identity and model-specific recovery path. Repeated writes can destroy evidence and compound a hardware or power fault.
