     Excepting burned in enforcement of SecureBoot style
     sig checking schemes, don't many phones now have known
     ways to import completely custom or original disk image,
     or buildup filesystem from scratch, after total erasure...
     dd if=/dev/random of=/dev/<phones_flash_media> bs=1m
     dd if=/dev/zero of=/dev/<phones_flash_media> bs=1m

   That's new to me, and is what I'm looking for. Where do I learn more?
