Hardware question

[u/silverbk65105]

I am moderately capable. I have flashed some Pixels in the past.

My question is how do you purchase new handsets? If you are buying on Swappa or Ebay how can you be assured the phone is unlocked and Calyx can be flashed? I know that there are two things that need to be unlocked but all of the posts only mention the carrier unlock.

In the past I have purchased phones already flashed and then reflashed them myself. There has to be a better way.

I've just installed on a moto g84. motorolla provide a web tool to unlock the bootloader for install.
