Vendor Name: Samsung
Device name: Galaxy S8+ (G955F)
Device CodeName: dream2lte
Version of Stock which existed previously: G955FXXUCDVG4 / G955FOXMCDUD1 (A9)
The device is Not rooted
Installed: R (official) ~ “stable” e-1.21-r-20240323388914-stable-dream2lte
For the clean installation I once again used the /e/asy installer v.20.1. It downloads version e-1.18-r-20231207360610-stable-dream2lte as the latest stable image. The /e/asy installer procedure was not processed to the final end. It stopped at the ‘OEM’ instruction and no longer offered a ‘Next’ button. Nevertheless, I was able to reboot and set up the system manually. Then the OTA update to /e/OS R (official) ~ ‘stable’ e-1.21-r took place.
I had a similar experience with the /e/asy installer here
