Zentalk Asus Community Contribution

I have a fully functional Asus Transformer TF300T that I’d like to unlock. Even after all these years, it still runs well! To make it usable again, I need to unlock the bootloader.

I tried using the Unlock Device App V7, but I keep getting a "network error."
Is there a workaround or updated method to unlock the TF300T in 2025?
