ok, so this seems to be a little different than i thought - and you'll excuse my ignorance about this, even if my use of language demonstrates the excuse isn't justified. i should really know far more about these walky-talkies that the kids are using than i actually do.
one way to remove the package would be to root in and take it out, which is the expected way to do it, and would keep the phone's proprietary software, but i intended from the start to wipe it right down. i could start talking about how you don't really know that it's clean until you format it, but that's actually secondary - i don't want the proprietary software, anyways. and, i guess this is where things get conceptually messy for somebody that has literally only held a smartphone in their hands a handful of times.
maybe it was naive, but i actually thought that the thing installed directly, and i'd be able to format and reinstall. so, i was trying to figure out how to find an android install disk on what? sd?
it turns out that it's more like flashing a bios, and that you kind of serial in over usb, like i did with the bus pirate in early 2014. so, you just need the right software and the right rom. easy. in theory.
except for the proprietary bit...
i'm going to spend some time reading up on custom roms just to try and figure out what they are, as maybe i'll find a rom that is perfectly suited. but, i'm an old nerd; i want to build my own device from the bottom up. just give me the boot loader, and let me build the rest myself.
as such, i expect to end up going with stock android and building up what i need from there, which is not going to be much at all. i don't want any passwords or personal data stored on this thing - it's a phone, and i don't expect to use it as much more than one. i just want it to be fast, spartan and safe.
i accidentally left it on overnight. it's charging. so, let's hope i can get the rom flashed by the afternoon.
