  • Did you try resetting it? With buttons combo (Volume up + Power button)

  • These always have a factory reset option somewhere, finding it can be difficult since it is often poorly, if at all, documented. Try various key combinations when powering on, the bad part of it is some of these require specific timing, like hold PWR+VOL UP+VOL DN until it vibrates then release PWR while holding other keys (just an example). If you can come up with any kind of model or manufacturer, we may be able to narrow it down more.
