There are few solutions for firmware problems

Upgrade your CR-10S machines using the firmware provide by bondtech for their DDS upgrade kit. If you choose
this firmware you have to install the 104gt-2 thermistor to the V6 hotend in our DDE kit (yellow shrink tube).

2. If you unable to upgrade the firmware just install the NTC100K B3950 thermistor (default thermistor on most
cheap Chinese printers) (black shrink tube one in the kit) and change the E-step to 415, try to adjust the Z-height
and manual leveling the bed
， tuning the hotend PID if it is possible then you will ready to print.
3. Custom-made your own firmware. There are plenty of instruction on internet that how to upgrade the firmware
