STM32 DFU Bootloader Deleted

Hello. I'm using an STBee evaluation board that has STM32103VE.
I accidentally overwritten the bootloader using the ULINK2 debugger using Keil.
I thought there should be no problem since I have the DFU hex file but after downloading it, I can only enter DFU mode when the ULINK debugger is connected as well.
Do you have any suggestions on how to return this to normal?
Thank you.
