I can't flash to STM32 MCUs any more. after I accidentally wrote to Option bytes in STM32 CubeProgramming.
Now status is

Read Out Protection:
RDP : 0xAA (Level 0, no protection)
BOR Level:
BOR_LEV : 0x0 (BOR Level 0, reset level threshold is around 1.7 V)
User Configuration:
nRST_STOP : 0x1 (No reset generated when entering Stop mode)

How do I do?
