Foreword
Yesterday, the PlankFilza file manager brought support for the iOS14 system, which can modify the system files in the jailbreak-free state, but after the editor’s test, there are not many permissions that can be modified, and the font cannot be modified. The system prompts Tones, WeChat prompts, etc.
Today I will share with you the use of the PlankFilza file manager to modify the operator's main display. I believe this is what many friends want to achieve. Follow the tutorial to modify it.
