# JJRC H67 - flashing ACRO (Silverware by NotFastEnuf)

Recently I successfully flashed ACRO firmware into my JJRC H67. It wasn’t easy, but I will show you how you can do it.

To do the whole procedure, you will need:

* ST-LINK V2,
    
* ST-LINK Utility app,
    
* and some cables.
    

Then you go through the steps listed on the [RCGroups forum](https://www.rcgroups.com/forums/showthread.php?2876797-Boldclash-bwhoop-B-03-opensource-firmware), but instead of BoldClash-BWHOOP-B-03 precompiled firmware, you will use [this binary](/assets/h67.hex). It is a compiled [Silverware by NotFastEnuf](https://github.com/NotFastEnuf/NFE_Silverware) with the following config:

```c
#define BWHOOP 
#define RX_BAYANG_PROTOCOL_TELEMETRY_AUTOBIND 
#define USE_MULTI 
// #define ARMING CHAN_5
```

If you are a Mac user, you are going to do some steps differently. You will need [Silverware Tools for macOS](https://simonernst.com/silverware/) since ST-LINK Utility is Windows-only software.

* in step “Erasing the factory firmware” instead of ST-LINK Utility user Unlocker to unlock the chip on your flight controller,
    
* in step “Flashing a new firmware” use the Flasher app. You just drag and drop your firmware file (e.g.: `h67.hex`) into the app’s window.
    

After this whole procedure, you will be able to bind to your Taranis as I described [here](/jjrc-h36-h67-taranis-multiprotocol).

I also gathered some additional materials you may find useful:
