Crankk official guide for onboarding a Bobcat Miner 300 G285 gateway

Please note that, at the moment, we recommend onboarding the Bobcat G285 only with the Hynix chip, as others tend to have problems. You can check this by opening the box, removing the metal cover, and locating the chip underneath it.


You can identify the 2GB Bobcat Miner 300 by examining the Serial Number located on its rear side. The Serial Number should start with G285. Alternatively, you can open the box and verify if the chip inside has G285 written on it.

Disclaimer: Advanced IT skills are a requirement before proceeding with the Bobcat Miner. Any issues resulting from non-compliance are solely your responsibility. Proceed at your own risk.
The onboarding process for the Bobcat will result in the deletion of the original stock Bobcat firmware. Crankk is not responsible for providing a backup.

The Bobcat G285, when operating with its original OS, may have the capability to boot from SD card if one is inserted. To explore this option, you can attempt it by flashing the CrankkOS image onto an SD card and then inserting it into the Bobcat. If this approach does not yield the desired results, please proceed with the following steps.

Please take note of potential Bobcat design flaws and hardware challenges outlined at the bottom of the guide.
If you’re considering dual mining Helium, please remember that you need to onboard it with Helium first.

Here are a few things you might need for this guide: T9 bit screwdriver and micro USB cable

In this guide, we will walk you through the process of flashing the CrankkOS image onto your 2GB Bobcat Miner 300 G285 using a Windows OS PC. Please note that this guide is also applicable to Linux and macOS systems. We will use ‘Bobcat Miner‘ to refer to the gateway.
