[Need testers] - Android 11 Alpha for Teracube 2e

** Warning **

  1. Please backup your data before proceeding. You will have to restore your data from Google backup.
  2. This is a test build. While it may function as expected, keep an eye out for issues!
  3. Not for the faint-hearted. This is Alpha software. If something goes wrong, you might have to re-flash using SP Flash Tool (SPFT). This build may only be flashed using SPFT. To restore previous builds, you will need to use SPFT as well; see below.
  4. Few apps might not be available in the App store like Netflix, Disney+ (this is due to the build not yet certified by Google), and others such as Google Pay may not work.

We have an initial Alpha version of Android 11 for Teracube 2e.

Known issues

  1. Fingerprint does not work
  2. Build is not certified yet, apps such as Google Pay and Netflix may not work.
  3. This is a very early build and may contain more issues.
  4. You will require SP Flash Tool to install this, and to flash back to the Android 10 build.
  5. The next Alpha/Beta build will also need SP Flash (can’t be upgraded over the air)

Known goodies

  1. Android 11 features
  2. Bluetooth skipping issue fixed (like SW16)
  3. LED blinking behavior is improved and can now be disabled completely.
  4. Sept 2021 security patches

Steps to install

  1. Set up SP Flash Tool by following Steps 1 and 2 of this guide.
  2. Download the Android 11 firmware package, extract it to your desktop.
  3. Load the firmware inside SP Flash (see the guide in step one for reference).
  4. Select “Firmware Upgrade” instead of “Download Only”. (DO NOT select “Format all”! Make sure it reads “Firmware Upgrade”).
  5. Power off your phone.
  6. Click the “Download” button in SPFT.
  7. Connect your phone; do not disconnect until the flash process is complete.

Steps to revert to Android 10
Follow this guide with a small twist - use the “Firmware upgrade” option in SP Flash.

Please post here if you are up for testing. Let us know how it went and post your questions/feedback here.


Alrighty… Got this installed last night after some issues with the driver. Went to use Maps this morning and noticed that it never asked for location permission, so when I went to navigate I had to manually enable the Location permission for Maps. I don’t recall that ever happening on any other phone I’ve had.

Aside from that it’s been fine so far.

Here’s another: I removed the search bar at the top of the home screen but I can’t move the At A Glance to the top (or anywhere at all, actually).

Another: I always set my Display size to Small and Font size to Large. In the camera app, this causes the 3x3 grid setting to be off-centered. Also in the camera app, I don’t see an option to save the location. Only after I manually grant the location permission did the camera save photo location.

Thanks @icantremember for all the feedback so far. Seems like location permission is being finicky. We will check out the camera feedback as well.

Here’s another: LTE indicator remains active in the status bar regardless of wifi connection, even when I have the Developer Setting “mobile data always active” set to Off.
