IDA reset function name

Question

I'd like to set the name of my renamed functions back to their actual ones. I've been able to generate the name sub_123456, but setting it with MakeName(addr, name) aswell as with MakeNameEx(addr, name, flags) always fail due to the reserved prefix.

Has somebody been able to achieve this already or do I have to use a custom prefix?

Thank you

If you pass an empty name, IDA will restore the automatically generated name. This usually works with functions and data.
