The installation of DivestOS Mobile on a Samsung Galaxy S4 GT-I9505 (jfltexx) was done via adb sideload without any special incidents.
Surprising was like for him as well as for me the automatic installation of “DivestOS Recovery” - a fork of “Lineage Recovery”.
Did I just overlook a corresponding hint about the automatic installation of “DivestOS Recovery”? At least the system was not also automatically encrypted like here with the LG G3.
Yes, in the “Developer Options” you will find a switch called "Update recovery ". This is a very handy feature of LineageOS 17.1, it can be used to update the build-in recovery with System OTA Updates. But - does this also work with “DivestOS Recovery”?
EDIT: Two pictures added
Note: The wallpaper for the home screen of the last two pictures was changed by me.
“DivestOS Recovery” is extremely dominant and persistent. Flashing of TWRP Recovery via Heimdall and immediate rebooting (three times for security reasons) into TWRP Recovery worked, but TWRP remains only temporarily available. After a system start into DivestOS and subsequent booting into the device recovery “DivestOS Recovery” is present again.
Well, “TWRP Recovery” might not be perfectly adapted for LineageOS 17.1 yet, but it usually works well with the original LOS 17.1 as well as unofficial LOS 17.1 distributions. To eliminate “DivestOS Recovery” for good, I had to flash the Android Stock ROM.
Even if nobody thinks it is the truth, I would have liked to report positive aspects, but this is the end of my DivestOS exploration.
