If the user searches for the appropriate TWRP version for the SM-G925F and SM-G920F model via the website https://twrp.me/Devices/Samsung/ the user ends up with the data:
Obviously! The development for TWRP zerofltexx & zeroltexx seems to have stopped at version 3.0.2-1 and TeamWin TWRP removed the files without comment.
Everything points to the use of twrp-3.3.1-0-zeroflte & -zerolte to add TWRP recovery to the Galaxy S6 / S6 edge.
The misleading model numbers of the Samsung Galaxy S6 & S6 edge as well as the empty links for the TWRP versions ("404 Page not found.) is an accidental action in the /e/ documentation and should be corrected immediately.
In the “new” /e/ documentation, the correct model names have now been assigned to the respective descriptions: tion Samsung Galaxy S6 l SM-G920F and Samsung Galaxy S6 edge | SM-G925F.
