Hello, I recently purchased a used Nokia 9210i, I was wondering if it can be brought to factory settings somehow (and have all applications that do not natively belong to the phone uninstalled) because I like to start using it from scratch, I also want to know what I should use to clean the internal LCD display, it's a bit dirty and I'm not sure if a piece of cloth very gently soaked in water will damage it or not.

Do a format. CRTL + F... maybe! If not, I don´t remenber well search the tips on 3lib.

About the format, I read how to do it but I still need some help, I understand that during startup when I see the nokia startup image (with the hands) I press a key combination and it enters formating mode, in the tutorial they said I must copy a file to the phone memory and another to the card, how and from where do I copy these files? Do I need to connect it to the computer? How exactly is this done?
