Faudio Fa4 Firmware Upd

If you can’t find any official update, assume — many budget TWS models are shipped with final firmware and never updated.

If you encounter a bricked unit after a failed update, contact FAudio support directly (support@faudio.com) with your serial number and a screenshot of the error. Most units can be recovered using a JTAG programmer, but that requires shipping the device back to the manufacturer. faudio fa4 firmware upd
