After trying out eOS for a bit on my Galaxy S9 I have decided to go back to revert back to the stock ROM. I was able to follow the instructions (at https://doc.e.foundation/pages/revert_samsung_to_stock_on_windows) to reinstall the stock ROM. However when my phone boots it says that my device is encrypted and asks for a key. Weird, because I am certain that I never encrypted my phone…
Doing some troubleshooting I reformatted my device and reinstalled eOS using TWRP. When the fresh install of eOS booted for the first time… it automatically started to encrypt my phone! I am now able to use my phone again using eOS, but the encryption settings don’t have a method to disable or view the key. How do I remove the encryption so that I can go back to stock?
I figured it out. Posting here in case it helps anyone else.
- Reformat using TWRP.
- Reinstall eOS using TWRP.
- Hold Vol+, Bixby, and Power buttons when exiting TWRP. This avoids booting into eOS, which avoids the device encryption.
- Follow the official guide to revert back to stock ROM.
