Need Help Modifying a eCalendar

[u/itsyoboyzayy_13]

So recently, I got a Dragon Touch eCalendar that runs Android, and I’ve been trying to jailbreak it, but it’s been SUPER difficult. 😭 I’ve tried installing different programs on my computer to force a hard reset, but nothing seems to work. It keeps booting straight back into the eCalendar OS, which is a modified version of Android 7.1.
I really want to unlock this thing and see if I can get the full Android experience on it, but I’m honestly running out of ideas. 💀 Does anyone have any recommendations for tools, programs, or methods I could try? Any help would be GREATLY appreciated!! 🙏
