How to unlock the STM32G031C8 chip after it is read protected?
That depends on which RDP level (Read Protection) is active: Level 2 is a one-way street and can no longer be unlocked. On the other hand, level 1 can be changed to level 0, details can be found in RM0444, section 3.5.1.
Google translates the answer to: 这�?�决于哪个 RDP 级别（读�?��?护）处于活动状�?：级别 2 是�?��?�街�?�，无法�?解�?。 �?�一方�?�，级别 1 �?�以更改为级别 0，详细信�?��?�以在 RM0444，第 3.5.1 节中找到。
Good luck!
