Wipe out eMMC before flashing new OS?

[zkajdan]

when I format I include the whole disk so there is just one partition.

For some reason Manjaro seems harder to record over,  so I zero wipe any sd cards before flashing a new OS to any cards that previously had Manjaro on them.

I am lucky in that I do have multiple Pine phones,  so I have one that I use as my daily driver,
  and several that I can test without the worry of the system 'breaking' as those are just my 'test' phones.

Thanks a lot, again, @bcnaz !

Yes, the old OS was indeed the Manjaro the phone came with ... so I'll use dd on it.

Sounds useful! In fact I already have 2 phones (although I'm just starting out) - with my first, I immediately ruined the SIM slot because I fell into the infamous use-nano-SIM-with adapter trap ... (I found the warnings against doing that only after I'd ruined it ...)
