Memup SlidePad 816P - Alwinner A20 weird bootloop - Android Q&A, Help & Troubleshooting

Hello, so 1y ago i tried to root an old tablet of my sister from her middle school, with all the school bloatware on it and it worked, and one time i messed with the recovery and when i rebooted the tablet, its like it was never used and i can't even install a Developer Shortcut app because it tells me that there is no space available (its force to install to the 1gb rom and not the integrated sdcard of 10gb for apps and data, here named SP816P).

}
the thing is that there is a lot of space and i don't understand that sh*t, and if u ask me why i'm trying to install a developer shorcut app is because the developer options are activated but hided in the settings menu so the only way left is to use an app. Anybody here know how to activate ADB so i can flash the tablet with PoenixSuit and a compatible stock rom?
here is screen of the ES file explorer pre-installed on it
Thanks for reading this thread and maybe help me, bye!

nevermind, locking this post because the screen has just broken, only a half of it work... i don't event know how i manage to broke it

2nd Gen XT1526 frp

Okay, I have searched everywhere online and can't Gina anything that is related to my issue. Keep in mind I do not own a pc please. I have a Moto E 2nd Gen (XT1526).

When I first got the phone I tried booting it up to quickly find that frp had been activated. I followed a few tutorials online and I actually got into the phone and can see all settings, but when I go to factory reset the phone via menu the option to confirm is greyed out
I can access everything in the settings I believe but cannot directly go to another application from the home screen. Half the time the menu and home button aren't even visible on the nav bar. If I create a guest account I can utilize everything ion the phone including home screen but cannot edit user settings that I would call "main settings". I will post pictures on order of how I even got to this point. Any help is hugely welcomed. Thanks in advance!
next step I was just getting out of the way
Now we have access to settings!
Please Help!

Would you know how this affect battery?
ONE GR8 8
Still no, I setup it today and I had half battery already. Will see from tommorow.
I installed the update but now it keeps crashing, making the phone freeze completely for a short period. Anyone know of a way to roll back?

Apps with usage access bug

I have Y5 prime has EMUI 8.0 based on Oreo 8.1
Got September security patch, installed it, ran into some problems, factory reseted it, then it was fine.
Afterwards, had this weird bug that prevent me from allowing apps to access data usage. I don't recall having that. I go to the menu through Settings>Apps and notifications>Special app access>usage access I can see apps which are allowed and those not. But i click and nothing happens. Any suggestions? I wanted to use some data montioring apps so it required this permission. Where other permissions can be toggled on/off normally (ex. Draw over other apps or Modify system settings)
I tried safe mode but with no luck.

I want to remove un important root files without being root

Ok, I use a Xiaomi Mi A3 I have android version 10 and I am not root. Why don't I become Root and end my problem? They are simply not worth it, the files that I want to delete are notification tones, calls, alarms that the phone brings by default.
There would be no problem if it weren't because they are like 200 tones, 200 tones ... I want to choose music as a tone, which should be fast but it is not, it takes a long time to find it. I know it is exaggerated but it bothers me a bit therefore I would like to know if there is any way to proceed with its respective elimination without being root.
Thank you very much for your help in advance, seriously this is like a small stone in the shoe.
Note: I am using google translate

System files as the mentioned 200+ .OGG-files only can get removed ( physically deleted ) by you if you have root access to them.

Recover a -deleted- app

So I removed the Galaxy Store app from my phone to test and see if I could reinstall it and use it as user app, that doesn't seem to be the case since it constantly crashes every time I open it
I don't really care that much about the app since the only thing I'm missing is the ability to download other fonts, but it's a bit awkward when I hit download more fonts and all I get is an App Manager screen.
So, is there any way I can maybe restore this app or getting the apk to work without having to reflash this thing yet again? Maybe an alternative app I can use that the system can recognize and get fonts from or anything of the sort?
bump
btw tried moving it to the sytem apps folder to see if that made a difference
nope
