(after rooting of course) I used an (uninstaller) app to uninstall chrome, i did this because i thought it would be saver then deleting stuff with a filemanager. After a reboot it went in a bootloop. I can not tell you what exactly went wrong there. I did not had this kind of behavior on other devices bevor.
Ok, that’s valuable info, then I guess we don’t want to do that.
The way to uninstall/deactivate (the command is uninstall, what it does is more deactivate) which was established in the topic I linked to doesn’t wreck the system, and Chrome doesn’t get updated, at least for me (via Play Store as long as I still had it active, and now via Aurora Store, which happily updates other Google stuff I left active).
I dont use chromebrowser, i use firefox. I like clean systems so chrome had to go. At least that was the plan… But thx to this forum i now know a lot more of reflashing stockdroids to a/b partitons.
