Flipsky ESC75100 Pro V2.0 firmware update via USB fails — VX5 remote not working

Build, Repair & Mod

Hi all,

I have a FSESC75100 Pro V2.0 with a VX5 remote. The VX5 does not work via PPM and needs UART. However when I try to update the firmware via VESC Tool 7.00 and USB, the connection drops immediately after connecting — “No firmware read response”.

The ESC connects briefly (I can see “Connected serial to cu.URT0”) but then loses connection before I can flash firmware.

Has anyone managed to update firmware on the FSESC75100 Pro V2.0? Any tips on how to keep the connection stable long enough to flash?

Thanks!

Problem solved. The USB-C cable I used was only for charging :zany_face:

Also watch out on some modern laptops the USB-C wont connect to the Flipsky ESC even with a data cable. using a HUB on USB-A to USB-C works fine.
