Firmware for Cadena CDT 1651SB

Often, difficulties arise with the Cadena CDT 1651SB firmware via the USB port. That is why experts advise to find the BIN / HEX image of the EEPROM 25Q32 chip on the Internet. The microcircuit is soldered, connected to the programmer, read out and saved. After that, the cleaning is performed and the firmware downloaded from the Internet is written into it. Then they are installed back into the tuner.

In order to independently program microcircuits, experts recommend purchasing a special programmer. However, don’t be discouraged by the lack of such a tool. In an emergency, you can use the thin steel blade of a disposable razor.

One by one, the conclusions of the microcircuits are heated, a blade is slipped under them and the microcircuit is soldered in order to install it in the programmer. It is important to be very careful not to damage the tracks on the tuner board. You can change the tuner firmware without soldering. To do this, you will need to take care of purchasing a special clip with an adapter, which is put on top of the microcircuit. Through the adapter, the cable is connected to the programmer. To avoid overloading the programmer, experts advise, before connecting the adapter, to take care of cutting the power path that comes to pin 8 of the microcircuits. Once the reading process is complete, the track is restored.
