Modifying Nextion Syscom?

Huallo huallo everyone! So whenever I flash a tft to my Nextion Intelligent 7.0’ series, I always see this ugly bitch text with bitchy english :frowning:
I want to make it better but I don’t know how. Digged into TFT, HMI, found nothing about them (as when you flash a new TFT with a new Editor version, it updates the firmware too). So I got into the Editor files itself, found the syscom.bin which has some text files like “updating…”, “sd card update” blablabla… Modified them, made a TFT and flashed it… You guessed it… NOTHING.
