I just purchased an Onn 8 inch Tablet from Walmart model number TBBVNC100005207. I've been looking for a system image to keep as a backup but I haven't been able to find one. What would be the simplest way to make a backup image myself? Is it possible without root? And if not, is there a way to root this tablet?

onn.8.tbbvnc.system.image.root.twrp.recovery


Although I am unable to answer elbastard question, I share his interest.
I too would like to know how to create a system.img
I too would like to root device.
I am unable to root TBBVNC100005207
Previously, I successfully rooted a 100005207
Sadly, I am aware TBBVNC may have eliminated mediatek (mtk-su) exploit
I am aware there is a NEW ONN.8.$100.android10 available I may also attempt root.
Root process I used on previous 100005207 does not work on newer TBBVNC model
TWRP flash process I used on 100005207 does not work on newer TBBVNC model.

I'm in process of doing out of box, initial wwr/ spflash read back and split. I can take some screenshots for your guide if wanted. But I guess you have them already
attached photo guide-wwr. Photo titles are the steps. May be better to add photos to a document, and expand on the steps.
But since everyone is busy with real life, this seems like at least a good start.
***EDIT--UPDATE***
Sorry i read the title wrong. I made a dump guide, not a flash guide

You're welcome to reference my thread and post a link to my server with the x003 and x002 stock images. SP Flash Tools is needed.

I plan on making a proper thread, perhaps this weekend, on how to backup with Wwr, and flash with SP Tools. I will try to upload updated images from the newest OTA.
I may even make a blog post with photos on my site.

I cannot find what that is referencing

I would also be interested in getting a hold of that boot.img. Have a boot looping ONN tablet that could use it.
