On Stock ROMs, the "Speed Key" (the little dots key) was hardcoded. On Custom ROMs, you can remap it to anything. Some users map it to toggle the flashlight or launch a terminal app, turning the Key2 into a true IT-admin tool. Summary: Is it worth it? If your Key2 is gathering dust because apps won't run or it's lagging: Yes. The feeling of typing on that physical keyboard while running clean, fast Android 12 is unmatched. It is the closest you will ever get to a "modern" keyboard phone. Publicagent Shay Sights Top
Surprisingly, running Android 11/12 (LineageOS) often yields better battery life than the stock BlackBerry OS. Why?

However, this is not a standard guide. The Key2 has locked bootloaders on most variants, making this a procedure that borders on hardware hacking.
To install a ROM, you must use a tool that exploits a vulnerability in the TrustZone (TZ) to bypass the signature check.
Head to XDA Developers Forums -> BlackBerry Key2 -> Original Development . Read the stickied threads for at least one hour before you type a single command. The Key2 community is small but incredibly helpful—don't be afraid to ask questions there.
This is a guide for the adventurous. The BlackBerry Key2 is one of the last great champions of the physical keyboard, but its software is stuck in the past. Installing a Custom ROM is the only way to drag this hardware into the modern Android era (Android 10, 11, or even 12/13).
The Key2 camera is mediocre at best. However, on Custom ROMs, you lose BlackBerry's image processing. You must install a GCam Mod (Google Camera port) to make the photos look decent. Without it, photos will look like watercolor paintings.
