SHFW is a custom firmware available for flashing via the Scooterhacking Utility app. Configuring it might be challenging for new users. This guide aims to provide a quick and easy way to understand the important basics.
1. Download the flashing app from [https://utility.cfw.sh/](https://utility.cfw.sh/).
2. Supported Scooter Models:
- **Ninebot G30**: You can flash this firmware if the DRV version is at 1.7.0 or below. For DRV versions above 1.7.0, you'll need an ST-link. Refer to [https://joeybabcock.me/wiki/STLink_Ninebot_Max_ESC](https://joeybabcock.me/wiki/STLink_Ninebot_Max_ESC) for more information.
**Warning**: Modifying field weakening settings without a deep understanding of the consequences can potentially lead to unstable or unsafe riding conditions. It's strongly recommended that you proceed with caution and, if unsure, consult with experts or seek guidance from the scooter hacking community or read articles on the matter.
From my own experience and testing, I've found that keeping the initial value at 0 and adjusting the other parameters to achieve around 30-35A of requested flux leads to the best riding experience. Therefore, the ideal outcome should fall within that range.
These calculations and principles have been used to configure the examples for the scooter models listed in this guide.
