Is using a custom ASIC firmware from BiXBiT free?

Our software for Antminer, Whatsminer is distributed for free. Please keep in mind that custom firmware includes Developers Fee, which is a reward for developers. Usually it is 1.8%-2.8% of the miner’s total hashrate which is automatically deducted during the work of the device.

Why the ASIC does not start after selecting a profile?

If you mean the very first run after flashing the device, it sometimes takes up to an hour for the inbuilt algorithm to finish configuring your ASIC.

How to bypass the “Cannot Find Signature” message during the flashing process of the ASIC?

Read our user manual for your specific miner version, it describes actions to eliminate this error, when it occurs.

Does the ASIC lose its warranty from the manufacturer when used with a custom firmware?

There is no definite answer. To avoid warranty issues, please use the firmware from the manufacturer.

Is it risky to use the custom firmware for ASIC from BiXBiT?

Absolutely not. All firmware revisions are thoroughly tested before each release. Moreover, all BiXBiT capacities have been running on these firmwares for many years.

Is BiXBiT AMS compatible with microprograms from other developers?

No. Our automated monitoring system is only compatible with our software.

Is it possible to revert the ASIC back to its original settings after using a custom firmware?

Yes, just bring back the official firmware in the usual way.

What level of knowledge is required to flash a miner?

We have specially made instructions for every version of the miner. Everything is described in a simple and clear way, so even a beginner can handle it. Besides, you are always backed with our team of technicians who are always in touch and willing to help.

APPENDIX 3.2 Writing an image to the SD card

It is recommended to pre-format an SD card with a capacity of 2 to 16 GB (inclusive). The formatting process is described in detail in this section.

Step 1. Run the "PhoenixCard" program (the folder with the "PhoenixCard" program is located in the archive with the firmware).
Step 2. In the main window, select the drive whose letter corresponds to your SD card.
Step 3. Click on the [Image] button - a file selection dialog box will appear.

Step 4. Find and select the file with the ".img" extension from the folder where you extracted the contents of the firmware archive.

Note

The file selection depends on the firmware version you plan to write to the SD card. This can be either the original factory firmware or a custom version — for example, ours from BiXBiT or from another developer. In any case, to write the firmware to the SD card, you must select a file with the ".img" extension. Pay attention: Files with the ".bin" extension are intended solely for installation via the WhatsMinerTool program and are not suitable for loading via an SD card.

Step 5. Make sure the Product parameter is selected. Click the [Burn] button.

Then, the process of flashing the SD card will begin.

If, after the process is complete, the SD card status bar lights up green for a moment, the firmware has been written successfully.

If, after the process is complete, the SD card status bar lights up green for a moment, the firmware has been written successfully
Additionally, the success of the firmware image writing process is confirmed by the lines:
[IMG File]Burn Success
[DATA File]Burn Success
Magic Complete
Burn End…

After completing the writing of the firmware image to the SD card, the "Autoplay for removable drives" function may automatically trigger, and the system may attempt to open the memory card. Since the written data resides in a hidden partition, Windows might incorrectly identify the card as corrupted and offer to format it. A similar warning may appear if you try to open the card manually via File Explorer.
Important: Do not confirm the formatting. Simply close the window by clicking the [Cancel] button or the [X] in the top-right corner.

In Windows File Explorer, the memory card will appear empty. However, the firmware image data for installing it on the ASIC is present on the SD card and resides in an unallocated area of the partition table.

If the operation fails, you will need to format the SD card again (a failure is indicated by a red status bar for the SD card or if the process takes more than a few minutes).
