Warning: Flashing a custom ROM on a BlackBerry Passport is not like flashing a Samsung Galaxy. BlackBerry locked the bootloader tighter than a Fort Knox vault. You cannot simply run fastboot oem unlock.

I ran LineageOS 14.1 on a BlackBerry Passport for three months in early 2026. Here is the honest log:

Morning: I take the phone off the charger (100%). I reply to five emails using the physical keyboard. Typing is euphoric. No touchscreen keyboard comes close. The square screen renders Slack threads perfectly.

Noon: I try to join a Zoom meeting. The app crashes. I join via the browser. The fan on the back of the Passport (yes, it has a cooling pipe) gets warm.

Afternoon: I order coffee using a Web App wrapper for Starbucks. It works. I take a photo of my dog. The photo has a purple tint; the white balance is broken.

Evening: The phone freezes while scrolling Reddit (Sync for Reddit legacy app). I hold Power + Volume Down for 10 seconds. It reboots. I miss the reliability of BlackBerry 10.

The takeaway: This is a secondary phone. If you are a writer, a journalist, or a keyboard fetishist, this is a distraction-free writing device (Termux + Vim = bliss). It is not a reliable daily driver.

This is the unicorn. For years, devs like Just4Fun and Thurask argued it was impossible. The Passport runs on the Snapdragon 801 (MSM8974). This chip has drivers locked down for Android 4.4 and 5.0. Getting Android 11 to boot requires reverse-engineering the GPU blobs and creating a Frankenstein kernel.

As of late 2023, a functional Alpha build of LineageOS 18.1 exists.
