In theory, it could be that a failed upgrade of the ANX7688 firmware caused it to become overly "chatty" on the I2C bus, which in turn made the WiFi or the modem confused, or even made further ANX7688 firmware upgrades impossible. As I said, this is pretty much theoretical, but it's worth a try to remove as many other devices from the I2C bus as possible before attemting one more ANX7688 firmware upgrade.
