Antminer S19j Pro (104Th) Firmware

Download Bitmain Antminer S19j Pro (104Th) newest online update firmware and SD card Firmware.

Bitmain Online Update Firmware of Antminer S19j Pro

Earlier in December 2022, Bitmain released their updated firmware for the S19 ASIC MinerS19J Pro models.
Here is a side-by-side comparison of the two modes on the new FW and the old FW in terms of performance.

S19j Pro merged firmware

The new FW’s default power mode is seemingly the same as the old firmware.
The low power mode does deliver the 25.5 W/Th that Bitmain promised, but it reduces hashrate by about 20%.

There is no additional autotuning downtime because it runs at a fixed frequency. Hashing begins as soon as the miner boots up.
Since the miner only pull about 8.7 amps on low power mode, people might be able to squeeze two miners on 20A circuits (I know it breaks the 80% rule, but also know that some people will still do it)
On the same miner, we also conducted this test using an AMLOGIC control board, and the outcomes for all three columns were identical.
In order to be able to underclock now, if your miner has an AMLOGIC board, you don’t need to replace it.
Although the customization options in this new firmware aren’t as extensive as those in Vnish or Braiins, we’re still glad to see Bitmain giving miners more choices.

Sometimes, your miner may stop mining because of firmware issue of the controller. In that case, you can fix the issue by upgrading the firmware. And also in some other cases, you may want to upgrade the firmware of your miner to the latest version so that your miner can attain a better performance.

Before updating the miner firmware, please make sure the miner type and firmware type match.

SD Card Firmware of Bitmain Antminer S19j Pro

Bitmain Antminer S19j Pro SD Card Firmware for BB control board only:

Bitmain Antminer S19j Pro SD Card Firmware for 7007 control board only:

Bitmain Antminer S19j Pro, A113D, Amlogic (AML) control board flash card package:

Flashing Instructions :

Tools Required:

  1. Hardware includes a computer (running Windows), a card reader, and the MicroSD card recommended capacity of less than 16GB. Larger capacity MicroSD cards are not recommended as they are very susceptible to errors.
  2. Software: Antminer S19j Pro card firmware and a decompression program (WINRAR is recommended).
  1. Insert MicroSD card into computer and format to FAT32.
  2. Unzip the downloaded image file and copy the contents to the MicroSD card.
  3. Remove the MicroSD card from the computer and insert it into the card slot on the control board.
  4. Power on the control board. Allow about 30 seconds for the files to load automatically. When loaded, the green indicator light will be steady on.
  5. Remove the MicroSD and restart the miner. In over 30 seconds, please reboot the miner. (NOTE: do not power off during the restart process; power failure will cause the OTP to fail to turn on which also damages the control board.)
  6. Power on the miner and access the miner interface. Remember to upgrade the latest official firmware online.

Custom Firmware of Bitmain Antminer S19j Pro

VNish firmware for S19j Pro

VNISH firmware is designed to safely overclock Antminer S19j Pro. It is distinguished by a fast start-up, a self-tuning function and an integrated anti-virus. Compared to the stock firmware from Bitmain, VNish firmware has a huge functionality that allows you to quickly and efficiently manage your ASICs and increase the profitability of your equipment by up to 50%. It includes a 2.8% devfee for developers.

1. Insert the SD card with VNISH firmware and turn on the miner, if you remove the SD card, the BITMAIN firmware will return:

For BB control board:

2. If you need to update the version of the already used VNISH firmware on the SD card, then you need to download the WEB version of the VNISH firmware and upload it through the UPGRADE function:

For BB control board:

BraiinsOS for S19j Pro

Braiins OS+ is autotuning mining firmware that aims to increase hashrate on Antminer S19j Pro, designed to improve efficiency as much as 25%. Braiins is completely reinvented firmware with Open Source code and the all important inclusion of StratumV2. Its 2.8% devfee cost can be negated by pointing the hashrate to Slushpool.

1. Factory restore the Antminer S19j Pro with the following SD card firmware (unzip to SD card):

For BB control board only:

For 7007 control board only:

2. Run BraiinsOS from the Micro SD Card by inserting and leaving the card in and powering on the unit. Unzip the following content to SD card with the following image:


Awesome Miner Firmware for S19j Pro

The Awesome Miner firmware supports display of power usage, LED flash, sleep mode, antivirus scan, and multiple predefined hashrate modes. All these features are integrated in Awesome Miner. 

A hashrate increase of 15% for Antminer S19j Pro. The power efficiency is improved by tuning of each individual ASIC chip.

  1. SD card images. The firmware must run directly from the SD card and cannot be installed on the Antminer: SD-antminer-s19jpro-awesome-v1.1.11
  2. Update your firmware through the web interface with the following image: antminer-s19jpro-awesome-v1.1.11-update

What is Firmware?

Let’s first define firmware.

In hardware devices, firmware is a type of software that can sometimes be updated by users. A wide variety of electronic products, including industrial robots, hard drives, computer keyboards, calculators, and remote controls, can use firmware.

Now that you are aware of what firmware is, let’s discuss why it needs to be updated.

Why Do We Need to Update the Firmware?

We are all aware that science and technology undergo continuous iterative updates, and firmware is no different. The mining machine can add some functions and operate more efficiently with the help of a firmware upgrade.

For instance, some firmware updates can be used to run programs that enhance miner performance while lowering power consumption. These firmware updates can reduce the amount of electricity miners use.

Additionally, some firmware updates can boost the miner’s processing power. By updating the firmware, more processing power can be obtained for the same machine. This type of firmware can boost miners’ mining profits.

Additionally, there is firmware that can improve restart procedures, high-temperature protection procedures, etc. for miners. Such firmware can help increase the miner’s dependability and guarantee its stable operation.

Even though the firmware is good, not all firmware updates can be done quickly. Numerous miners downloaded and updated the machine’s firmware as soon as they learned that a particular firmware could significantly boost computing power, regardless of the firmware’s source. As a result, the device performs erratically and might even lead to the poisoning of the mining device and the theft of computing power. As a result, it is advised that you only use the mining machine’s official firmware and not any other kind.
