[Walmart Onn Tablets General] KaosKreationz:
Ok I'm finally able to report I have successfully Unbricked the Walmart ONN 100003562.

Using various bits of information scattered throughout the Walmart ONN general threads section so If anyone else runs into this issue i have the fix.

Step 1

Download both the FULL FACTORY firmware and the Update firmware from this awesome guys google drive. here's the link https://drive.google.com/drive/folde...5k?usp=sharing.

Starting with the Full stock flash all available .img .bin into the proper locations via fastboot.

when flashing the vbmetas use "fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img" you should get a result like this if done properly.

"Rewriting vbmeta struct at offset: 0

also take note that there are a few .bin and .img locations that aren't the same location as the name. I used the scatter file in wwrmtk 2.51 to get the proper locations however I will copy and paste all my commands and results here.

after you rewrite all .img .bin you have to start over with the update .img and .bin.

here are the commands and results I used to successfully unbrick the device.
