[Walmart Onn Tablets General] leakydroid:
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.

#20200706...Im including Specs, elbastardson can compare

#20200706...I am unsure if pulling image = dumping firmware = making backup of system image

#20200706...Ive included links to info on tools for backing and flashing

My.Observation

It appears to "Backup" image you use
#t.program...wwr
I cannot find what that is referencing
IT appearss
#t.program...spflash
is usefull for
#v.flash
of pre-existing
#t.file.img...system.image

My.Observation

I am unsure if the following terms all mean the same
#v.pull
#t.file.img
&
#v.dump
#t.file...firmware
&
make
#v.backup
#t.file.img...system.image

My.Observation
