IMPORTANT: This firmware is compatible only with the Antminer S21 Imm.
Before installation, make sure you have the correct firmware version for your device.
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.
Firmware for all models can be found here: Firmware for All Models
To install the firmware, use an SD card (maximum 16GB, FAT32 format).
IMPORTANT: If you want to flash the Antminer S21 Imm 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.
Example: asicdip-s19-88-xil-sd-v1.2.0-rc4-update
