Lenovo Tab 2 A7-30HC Stuck after trying to Upgrade/Update system

So uh, I wanted to update/upgrade my Lenovo Tab 2 A7-30HC. But I remembered that I can't upgrade or update if Im rooted. So I unrooted myself using Kingroot then I tried upgrading/updating the tablet. After it was done it gave me a error and now I'm stuck at the recovery options thing. Well, I dont have any custom recovery nor do I have an SD Card. So now I can't use my tablet. I tried restoring data but it kept saying I had no SD Card. I got to the point where I tried all options and accidentally wiped everything.
Now I cant use it. Please help me. This is my only tablet.





I can try to provide more details if asked.

I made this account so I can ask this since even my sister dont know how to fix it
