Looks like this will not happen without reflashing. As long as you can boot into fastboot mode you can start again. Does it help to visualise that the phone has 3 modes
- Fastboot – always active as a communication channel – we tend to say the phone is not bricked if you have fastboot.
- Recovery – this is the stage where we break the Google / Android hold on the device and is critical to get right. If you are at all uncertain why you cannot find Format data from the guide I copied please take a photo next time.
- System – should be straightforward as long as all Recovery tasks are complete.
So I think you show an image of the Red warning and Orange warning, explained on same links as shown for Yellow warning.
Good luck with your second attempt. 
There is this guide for a different perspective [HOWTO] an Unified Install Guide Project for /e/. Don’t hesitate to ask if anything is unclear.
