Full rebase onto 4.19, MediaTek performance and upstream Google + Linux security improvements, and more; changes since emerald’s A11 SW5 build:

  • Common kernel-4.19 support
  • Added some critical upstream security patches

  • Added double tap to sleep on home screen
  • Added clear all to home screen

  • Switch to in-house Camera app for faster and more reliable image capture
  • Changed system accents to blue
  • Added GMS common default wallpaper (old wallpapers retained)
  • Added ringtones and sounds from Unified (old sounds retained)
  • Improved IMS support for many Europe carriers
  • Added new bootloader graphics

Steps to Upgrade from Android 10 (SW6, SW16, EEA1) or Android 11 (11.0.X):

  1. Download the upgrade zip file directly on the phone (or transfer the zip to the phone).
  2. Goto Settings > System > Teracube Updater
  3. Click top-right 3 dots > Local update
  4. Tap “Internal storage” and browse to Downloads or wherever you transferred/downloaded the update zip file.
    Note 1 : If Internal storage does not show anything, then reboot the phone.
    Note 2 : Do not download the update to SD card.
  5. Select the file and continue the update process.
  6. It will take a while. The phone will power off and restart by itself. Don’t press power button.

Do note, some users have reported that they lose their launcher - icon and widget arrangement. We’d suggest you take a screenshot of your homescreen before performing the update!

In the past the [upgrade.zip] was a link to download. But this time not. Where can I find the zip file?

We are currently investigating an SMS issue in the build. Hence the link is taken down.

Update: Issues fixed and the 11.0.4 build is live again.


Any luck in figuring out the download 11.0.4 issue?

where is the download link??

@mastershake : See comment 2 or 3 lines above from Sharad. (Aug 22nd)

Both known issues have been fixed and the 11.0.4 link is live again. Please proceed to download and install.

I was updating from 11.0.2 in Germany and it works perfectly! (I restarted my phone bevore updating.)
All small issues where gone and my missed features (battery load to 80% only, better symbols in upper tray etc.) are working like before in Android 10.
The discussed issues are n/a for me. So its fine. :slight_smile:
But I am a bit disappointed, that the security updates are from end of last year und the google ones from april 2022. That could be better…

Ok updated and all is well and has been a few days. Thanks

Hi all! Phone seems a bit slow after the update to 11.0.4 (5th iteration), but after a while (1 reboot made) the speed is okay, camera app is different (why?), also Android security update is way outdated. Otherwise, it seems like a solid update, thanks Teracube team!

Yes - this is the new app we launched sometime back. Much faster and menu options are also laid out better than our original app.

First update attempt seems to have not been entirely successful. Somewhat over 30 minutes at the upgrade spin after reboot, then into a “unable to load system” recovery screen. Fortunately, telling it to try again DID boot to system, and I’m back into my phone… still on 11.0.2+b1a2332.user though. I’ll try again when I have 45-90 minutes to burn. Might be a day or three though.

5G works here. (Unifi Accesspoint)

So is this still in beta or good for general population download?

11.0.4 update is stable and good for the general population globally.

I’m waiting for a stable release to be pushed over the air.

With 3 more flashes (total of four) I’m on 11.0.4 now without losing any data from 11.0.2 where I’d been. Yay.

Interesting. In 11.0.4 Duraspeed is back, and Live Wallpaper is broken again. Feels a lot like being back on 10.
