I have a lot of old phones that I never got rid of. Is there a definitive list of devices capable of being rooted? From what I understand, the bootloader is locked on all of them. How do I figure out how to root in the first place? The internet plagues me with scamware search results (useless “root tools”). Direct answers are welcome
One place to look is here

Or search on the LineageOS website. Of course, there are other alternative ROMs, but some of them are based on Lineage.
Beyond that, the xda developers forums are a good spot to look as well.
