Just sharing some information on my success with migrating to /e/ OS on these seemingly stubborn phones…

    -Flash with OOS Local Update Utility again.
    -Reboot

    -OEM Unlock = Enabled (SIM Card needed) *may be greyed out, unlock done automatically by OOS
    -USB Debugging = Enabled
    -Shutdown \ Power On
    -Verify Fastboot is working in Slot A or you’ll find yourself in a spin of mass confusion! See this post and thank you, @chrisrg .
    -Follow instructions carefully except flash the “dtbo”, “vendor_boot”, and “recovery image” in one Fastboot session. Manually power off device, manually access Fastboot, boot into the Recovery through Fastboot menu.

[ NOTES ]

-With the phone off, hold both volume buttons + power button to enter EDL Mode. Stop and close MSMTools after flashing is complete!
-Use ADB to enter Fastboot where possible. Two other options are 1) with the phone off, hold both volume buttons after hitting power button and feeling the quick vibrate or 2) with the phone off or rebooting, hold volume down and power button with the phone off or rebooting. The latter seems to only work after flashing a recovery image.
-Volume up button + power button to force a reboot.
-Unplugging after flashing with Fastboot may be a required step before power cycling the device.
-Do not modify the filenames of the ZIP files containing the ROMs due to OOS checksums.
-The /e/OS ZIP installation fails to verify a signature at the 47% mark.
-The /e/OS install did not indicate a success after completing Step 2.
-Despite the two oddities above, the install was a success and no issues to report.
-This entire process was performed on 3 1+ 9 Pro phones (LE2125).
