I understand that the registers are write protected and you have a clock synchronization issue, but I can not find the cube HAL level calls to do this.

What's the point of using Cube, if it's harder than reading the manual and writing a couple of assignments into registers?

Try to look at the examples in Cube.

I am using the HAL_RTC_SetTime(&hrtc, &stimestructureput, RTC_FORMAT_BIN); which says it is doing these steps but it is failing to get the RTC back in init mode so the value can be changed.

The ever so intuitive answer was to change StoreOperation from SET to RESET now it works
