What happens to all the files, folders, and data on a phone when you flash it?
I know there are files on the phone that ID it to the provider. I think it's in the EFS folder, but in all the guides I've read and YouTubes I've watch, not one of them mentions copying anything first nor does it say anything about putting a file back.
Some of the guides I've read make it sound like you wipe everything down to basic hardware before flashing a ROM and kernel back onto the phone.
Does anybody know of a really, really basic guide to what happens?
Most of the time I learn by trial and error. I take it apart and see how it works. I have 4 laptops in varies stages of repair to prove it. But like I said, I only have one phone and I can't spend another $300 just to have another phone to tear down.
On another note...is there a way to set up a sig on this forum?
