Steps to Upgrade:

1. Download the upgrade zip file directly on the phone (or transfer the zip to the phone).
2. Goto Settings > System > Updater (or 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.
   Note 3 : Before you update, make sure you have at least 6GB of free storage and your battery is at least 50% charged. This will help ensure a smooth update process.
5. Select the file and continue the update process.
   Note: If the Updater closes or crashes, then try again.
6. Upgrade process will take a while.
7. Reboot the phone after the updater says “Update installed”.
8. First boot after upgrade can take several minutes.

Do note, after the update, you’ll need to re-enroll your fingerprint and 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!

Let us know how it went and post your questions/feedback here. Please keep the comments related to this update itself.

If you experience any errors/issues, you can install the original factory software using the automated installer or SP Flash.

This is great. I installed the Lineageos version of Android 14 from this thread early in 2024 and have been looking forward to updates. Can I smoothly update from the LOS version to this one? Thanks.

Since they’re different base levels, you’ll likely need to get back onto Android stock first. You should be able to begin with the initial SP Flash link from the top post, then Android 13 ([Certified] Android 13.2.1 for Teracube 2e Emerald (SN:2021)), and finally Android 14 from above.
That being said, SP Flash should work even if your phone can’t boot, long as the download partition doesn’t get corrupted, so you can try to dirty flash from Lineage if you like, just expect it to not go great and almost certainly need a reflash, whether back to Lineage or using SP Flash to get back to the stock experience.
