Ok, I might have found at least something regarding IMEI editing in Pixel 6.
The most interesting part is that I **had to** use my carrier's personal account page to verify the change is successful (by viewing which phone model the carrier detects), because whatever is displayed at `*#06#` or `*#*#info#*#*` does not change with this hack. So my method is going to only change whatever the network sees. Exactly the opposite to what those buffoons were stating.
Stay tuned.
