Could look scary, but Step by Step, One thing after another it is clear…
- you cannot start system normal mode
- you cannot start to Recovery mode
So i propose to first flash a working recovery (could be TWRP or the recovery-e)
then
- try a normal boot
- If it don’t boot, re-install /e/ from the recovery
The main advise is to not wipe or format the /data partition so no factory-reset as far as possible.
for a larger understanding of the install process, have a read :
- Rely on Install /e/OS on a OnePlus 5 - “cheeseburger” to pickup the commands,
- Also Download TWRP for cheeseburger_dumpling and/or /e/OS community cheeseburger download to get the files
