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.

4.1 Preparation for Installing Bixbit Firmware

Install the latest version of WhatsMinerTool. Using outdated versions may cause issues during firmware installation.

Download the BiXBiT Firmware archive and extract its contents into a separate folder
Check the control board model and the version (release date) of the currently installed firmware. This can be done using WhatsMinerTool:

or by viewing it in the Status → Overview tab in the ASIC web interface:
To install the firmware, select the appropriate option depending on the control board model (CB) and the current factory firmware version:

Important:
The firmware installation method, as well as the firmware files selected during installation, are determined by the control board model and the current firmware version, not by the miner model itself.

Control Board Model	Factory Firmware Version	Actions
H3/H6/H6OS	Any	Use WhatsMinerTool and the file `Whatsminer-ALL-Models_x.x.x.x.bin`
H616	For M2X series devices with a factory firmware version installed prior to December 13, 2023	Use WhatsMinerTool and the file `Whatsminer-ALL-Models_x.x.x.x_h616-before20231213.bin`, then install the main file `Whatsminer-ALL-Models_x.x.x.x.bin`
H616	For M3X, M5X, and M6X devices with any installed version of factory firmware or BiXBiT firmware.	Install an intermediate firmware version via SD card (`Whatsminer-ALL-Models_X.X.X.X.X_h616-after20231213.img`), then use WhatsMinerTool and the file `Whatsminer-ALL-Models_x.x.x.x.bin`
H3/H6/H6OS	Update BiXBiT firmware	Use WhatsMinerTool and the file `Whatsminer-ALL-Models_x.x.x.x.bin`

Installing firmware via an SD card completely resets all device settings, deletes logs, and removes traces of custom firmware. This allows you to resolve issues caused by incorrectly installed firmware or incorrect user settings.

Recommendation before sending a device for warranty service:
If custom firmware was installed on the device, be sure to reinstall the factory firmware via an SD card. This will remove all traces of third-party software and reduce the risk of warranty service denial. The use of custom firmware is an official ground for refusing warranty repairs.
