The most productive thing will be to keep the phone in Fastboot mode.
This is the command line install page Install /e/OS on a Nothing Nothing CMF Phone 1 - “tetris” (already mentioned above).
Did you rule out the possibility:
This will be the most simple thing! The Installer is quite new; it is unclear if the Installer will recognise the phone in Fastboot mode, but if it does it is expected to pick up at a suitable point. (A fairly high chance it will simply report unrecognised device, or so.)
The install page is looks a little intimidating … but the phone was already unlocked, and the install reported completed so you are safe to collect the latest download from the top line of this page /e/OS official tetris download.
… and move straight to the section
Installing /e/OS
Tip: For Windows users, we advise to use Git Bash. For more info about Downloads and Installation see Official Documentation
This will allow you to run a Linux script safely in Windows.
Now follow the four sections below … but I will add one item for reassurance.
- and 2.
Unzip your download and extract. Confirm that extracted directory contains …
- You are in Fastboot mode
- Make sure you are in the current directory which contains the
flash_tetris_factory.sh
file.
Right click → Git Bash here
Execute the following command:
fastboot devices
this is expected to answer, 123xyz456 tetris / fastboot
any thing like this, the phone self-identifies.
Return to the original instructions
Execute the following command:
chmod +x flash_tetris_factory.sh && ./flash_tetris_factory.sh
The script will flash all required files and will wait for input at the last step.
Good luck.
