This is superseded by the Pie beta builds meanwhile, see this post: [discontinued] [UNOFFICIAL BUILD] Pi/e/ test ROM for the OnePlus 5 - "cheeseburger"
================================================
Hi folks,
for anyone interessted in running /e/ 0.7 on cheesburger here is an unofficial build that receives OTAs on a daily basis:
https://eota.digitalkr.am/builds/full/unofficial/cheeseburger/
EDIT: This is the Pie beta! Use with caution
(works pretty good for me but no guarantees or whatsoever - use at your own risk)
WARNING: There are some quirks in the installation process depending on from “where” (as in which ROM in which version you are coming).
See those issues:

SUMMARY:
If you are coming from OxygenOS Nougat, LOS 14.1, or e 0.1 first manage the upgrade to Latest Oreo OxygenOS (with Treble support) - find ZIP here https://www.oneplus.com/de/support/softwareupgrade/details?code=5)
WARNING: Have a good data backup available - this upgrade is a pain. When you run Oxy Nougat you can’t go to latest directly but need to start with 5.0.1, then latest 5.0.x and then latest 5.1.x
HINT: blu_spark TWRP for cheesburger in a pre-treble version helps to flash from 5.0.1 onwards up until to the point where treble is enabled then use latest TWRP (blu_spark has no issues with unlocked bootloader)
If you com from latest Oxy Oreo / LOS 15.1 there should be no issues
