I have been patiently waiting for an OTA update for a Samsung S9 sold on the esolutions webshop that is running Android 8. I’ve slowly come to realize that this will probably never happen and that I will probably need to do this myself.
Could someone here point me to step by step instructions on how to update the S9 from Orea to something more modern?
I’ve searched through the documentation and how-tos, but all of the docs I’ve found requires the reader to make several guesses as how to proceed (i.e., instructions like “go to this external web site and figure out for yourself what needs to be backed up, whether you need to worry about dm-verity, and which files you need to download, etc.”). In particular, I was about to install TWRP, when by chance I found out that this was in fact already installed… Given that the S9 was sold by esolutions, it seem to me that they should have a specific how-to on how to upgrade the few phones that they sold. After shelling out the money to get a degoogled phone, the last thing I want to do is brick it when trying to update it.
