However, my device doesn't have an joystick.
I'm not even sure, that it's really an advantage, as I got it handed over as an Athena anyways.
I'd highly appreciate it, if somebody could tell me, which device this is from the photo I attached and maybe also give me 'hard-reset-instructions' for whichever device this is.
I think you have a problem
Your keyboard is from an Advantage1 (X7500) but the main device is an X7510 though I don't recognise the small feature above the Home button. The 2 keyboards are not fully compatible with each other as the genuine X7510 keyboard has an extra row of characters and haptic feedback.
The instruction you are getting for the hard reset is for the older model, so it is possible that someone has installed a modified X7500 ROM?
Anyway, as the previous poster said, follow the Voliume Down/Reset process then when the instruction comes up, press Power to reset or Camera to abort.
Once it resets,I'd try looking at which ROM versions you have.
