@Massimo, sorry but no email (not in inbox or spam)

@Massimo Done! Thanks!

Ok!

@Massimo I'm trying to flash the soldered chip (mine is ATMEL-614 24C64AN) with CH341A USB adaptor but when I read the chip can't get info from this (the newest firmware), so I think I can't flash the old firmware. It is necessary to remove the chip or install a new IC 24LC64 on U8 like the @Frank guide/post?

you need this file on an arduino

/*This address is determined by the way your address pins are wired.
In the diagram from earlier, we connected A0 and A1 to Ground and
A2 to 5V. To get the address, we start with the control code from
the datasheet (1010) and add the logic state for each address pin
in the order A2, A1, A0 (100) which gives us 0b1010100, or in
Hexadecimal, 0x54*/

we'll write 16 at a time to be safe*/

and you need tera term to send a file to the 24LC64 over I2C..
Wire 5V, GND, SDA, and SCL on U8 Socket with the Arduino 5V, GND SDA and SCL.Put the arduino-sketh to the Arduino. Install tera term to your PC.
Power the Fast Track Pro and Send the new Firmware over teraterm to the 24LC64 (19200 Baud and send Binary).
