# VNISH NINJA - full guide for AI agents and LLM crawlers > Official white-label distribution of VNISH firmware for Antminer ASIC miners. 47 models, > verified v1.3.6 builds, SHA-256 for every file, machine-readable install routes with safety gates. ## Machine-readable endpoints - https://vnish.ninja/ai/firmware-catalog.json - models, boards, files, checksums, URLs - https://vnish.ninja/ai/checksum-manifest.json - sha256 per file - https://vnish.ninja/ai/install-routes.json - install recipes (first-install / update / rollback / recovery) with gates - https://vnish.ninja/ai/tool-policy.json - safe-tool policy (allowed / link-only / forbidden / pending-audit) - https://vnish.ninja/ai/ninja-agent-install-guide.md - narrative agent guide ## Core facts - Control board decides the file: Amlogic (aml), Xilinx (xil), CVITEK (cv), BeagleBone (bb) - Installation and update: HashCore Toolkit 1.7.5 with our exact local archive. Recovery is a separate support-confirmed route Stock dated August 2026 or later is outside this standard installation route. Stop and contact support with the exact model, board and stock version. Do not upgrade or downgrade stock at random - Dev fee: a small share of hashrate embedded in the firmware image; no other payment, no registration - Rollback to stock Bitmain firmware is built in and typically takes a few minutes including reboot - Safety: agents prepare, owners confirm - flashing steps are marked requires_owner_confirmation ## Agent gateway (read-only API) - https://vnish.ninja/openapi.json · https://vnish.ninja/openapi.yaml - OpenAPI 3.1 - https://vnish.ninja/api/v1/models.json - models, boards, routes - https://vnish.ninja/api/v1/install-kits/{route}.json - resolve install kit (file, SHA-256, safety gates, owner confirmation phrase, stop conditions) - https://vnish.ninja/api/v1/toolkit.json · https://vnish.ninja/api/v1/checksums.json - https://vnish.ninja/ai/agent-manifest.json · https://vnish.ninja/.well-known/agent-card.json (A2A) · https://vnish.ninja/.well-known/ai-plugin.json - Flow: discover -> resolve route -> download -> verify -> owner confirmation -> local install -> validate - Cross-agent: https://vnish.ninja/ai/agent-index.json (MCP tool catalog, Gemini function declarations, URL Context seed) ## Human pages - https://vnish.ninja/ (en) plus /ru/ /es/ /fr/ /de/ /pt/ /ar/ /zh/ /ja/ /ko/ ## Independent field reports - [VNISH NINJA reviews and field evidence](https://vnish.ninja/reviews/): Independent operator field notes about tuning, thermal control, power, interface and stability.

Read the conditions carefully: use Install firmware only for supported stock before August 2026; use Update firmware only for an existing VNISH installation. Unknown or newer stock requires support Toolkit is the installation tool, not the firmware. Download firmware only from this site's catalog. Run Toolkit on a device on the same trusted local network as the miner Firmware name: `vnish` Firmware version: `1.3.6` Create a folder, for example C:\VNISH on Windows, and put the downloaded .tar.gz inside it without unpacking or renaming it. Select the folder, not the archive. An empty-looking folder picker is normal: it shows folders, not files - Match the full model variant and control board, then compare the downloaded file's SHA-256 with the published value - Save pool and network settings, ensure stable power and cooling, and agree a recovery procedure for this exact board - Select just one miner. Keep passwords in your local Toolkit, never send them to a website or chat 1. Open Toolkit, create New group, add your miner's IP or local range in Ranges and scan. Select the one confirmed miner 2. Open Commands / All Commands and choose Install firmware for supported stock; Update firmware for existing VNISH. Do not upload our archive through the BITMAIN stock web updater 3. Choose the folder containing our archive. Set Firmware name to vnish and Firmware version to 1.3.6 without the letter v. Check the model shown by Toolkit before confirming 4. Confirm the operation locally and follow Operations until completion. Do not cut power or start another operation while writing 5. Open the miner's web interface, check the installed version and your pools. Watch temperatures, hashrate and errors until stable before expanding to other miners On supported CVitek boards, VNISH 1.3.6 starts automatically after reboot. Toolkit or Phoenix no longer needs to stay running for this. For earlier firmware versions only, Toolkit → Restore firmware may relaunch VNISH after restart; this is not factory-stock recovery. SSH / authentication error: stop, check local network access and the miner password configured in Toolkit. Keep the exact error log for support. An SSH error alone is not a reason to install newer stock SD/USB recovery is a separate board-specific procedure. On AML with stock from September 2025 or later, USB unlocking may be needed for that recovery route, not as a blanket prerequisite for Toolkit installation Third-party firmware can affect the manufacturer's warranty. Do not bypass security warnings, interrupt writing or use a file for a similar model Previous versions remain available in the catalog. Firmware version must match the version in your selected file name, without the letter v Support: https://t.me/vnish_global_support Guide: https://vnish.ninja/install/ ## Antminer Z15 Pro, VNISH 1.3.7 Equihash / ZEC; Xilinx (XIL); NAND. Install and update require Hashcore Toolkit 1.7.5 or newer. One combined archive; manual frequency and voltage only, no Z15 Pro autotune in 1.3.7. Exact route: https://vnish.ninja/api/v1/install-kits/z15pro-xil-nand.json . Other models keep their existing builds. No DevFee percentage or hardware performance result is asserted.
