Antminer S19a 1.2.6 rc4

Release 1.2.6 rc4

VNISH Original Firmware for Antminer S19a

IMPORTANT: This firmware is compatible only with the Antminer S19a.

Before installation, make sure you have the correct firmware version for your device.

Important Note:

Check the date of the stock firmware. If the stock BITMAIN firmware is from March 2024 or later, you need to downgrade the firmware version using the image from Series 21 (2024 Unlock) or Series 19 (Stock Firmware) for your model and control board type.

Available Firmware Versions:

Firmware for all models can be found here: Firmware for All Models

Firmware Installation Guide

To install the firmware, use an SD card (maximum 16GB, FAT32 format).

1. Download the Firmware
Download the firmware file for your Antminer S19a control board version (the board version is indicated on the white label on the board cover). Unzip the archive and transfer the files to the SD card.
2. Insert the SD Card
Insert the SD card with the VNISH firmware into the device and turn on the miner.
3. Return to Stock Firmware
If you remove the SD card, the device will return to the stock BITMAIN firmware.
4. Firmware Update
For firmware update, download the web version of the firmware and upload it via the UPGRАDE function.
5. Power Supply Update
If the miner's power consumption exceeds 4600 watts, update the power supply according to the modification instructions.

How to Flash Directly to NAND Without an SD Card

IMPORTANT: If you want to flash the Antminer S19a with a Zylinx (xilinx) control board directly to NAND memory without using an SD card, use the TOOLKIT PACK for automatic firmware installation on your devices.

NAND INSTALL: To install the firmware, you must use TOOLKIT. If you are unsure about the model and type of your control board, download the guide for models and board types here.

To get started, download the TOOLKIT PACK (includes firmware for all models). TOOLKIT PACK will automatically select the necessary firmware during installation.

You can also download the TOOLKIT installation file and select the firmware for your control board model and type. Firmware files are available here.

Presets for Series 21, 19, and L7 can be found here.
