I tried to do it in the more advanced way, but I had never done anything like that before and I consider myself moderately technical. I used a simpler bootloader to get Frankel (the latest grapheneOS for Pixel 10. I have a basic Pixel 10, not the pro or fold) installed. I was apprehensive, but it seemed to go on fine. I am able to sandbox any google shit I do need (and it isn’t much) and I was able to get whatsapp with my old shit on it because my family is still using it for reasons. I am using K-9 as an email client for my gmail, which does help (or so I was told) limit the amount of information google gets on my usage when I check my email.
