1. Understanding the Firmware Situation

Unlike major brands like Rigol or Siglent, FNIRSI does not host a centralized, official "download center" for legacy firmware. Firmware updates are typically distributed via:

• Official Channels: The manufacturer occasionally releases updates on the product's Amazon/AliExpress page or via their official YouTube channel.
• Community Forums: The most active development and bug fixing happens on the EEVblog Forum. Independent developers often fix bugs that the manufacturer ignores.

Important Note on Hardware Revisions: Before flashing any firmware, you must check your hardware version. The TC2 has gone through several board revisions (e.g., older screens vs. newer IPS screens). Flashing firmware meant for a different screen revision can result in an inverted display or, in rare cases, a bricked device.
