well, guess that was too early.
reboots are back, frequency went down to like 2 a day and the impact it has on the usage has improved a lot. Its lagging way less after the reboots.

What is your battery’s age, and about what runtime do you get?
Do you notice if the reboots happen when it is hot, or if you’re heavily using the device?
Is this update confirmed to work with AT&T?
I just exchanged my battery a couple of weeks ago so i have no issues with the runtime, especially compared to the previous battery.
I can’t see a link between temperature and usage, it happened on either end of the scale for both

At this juncture, I’d suggest reaching out to support@myteracube.com to discuss warranty repair or replacement for your phone.
I repaired my Issues !!! No more reboots or crashing apps. 
Probably not all steps needed but this worked for me.
- Backup to Google Backup (system > Backup)
- I have taken out my sd Card.
- Backup of /storage/emulated/0 with “DriveSync to GoogleDrive”
- I followed this reset manuell for Android 13 Link
- Skipped connection to google account
- Download upgrade zip and Upgrade to 14
- Connecting android to GoogleAccount
- Restore of last Google Backup
- Restore of /storage/emulated/0 with “DriveSync to GoogleDrive”
- insert cd card

unfortunately the Issues are back.
Over time the Phone got slower and slower at times.
Now I’m back at the same State. 1-2 Reboots a day and random freezing apps with reboot after 5min

No, sorry. It’s the same development. First it’s better and then the Issues creep back. Since yesterday it is back to normal.
Is there a Teracube 3e in development? I assume the cersion 14.1.0 just needs better hardware
Yes it has been tested (The issue has been isolated now and every other builds will always have it working)

I received a refurbished phone today, which shipped with Android 11. I followed the advice to install Android 13 first, using the 13.1.1. emerald build. This first step worked fine on the first attempt. However, from there when I tried to manually update to 14.1.0, I kept getting the error “unable to load package.” However, the updater APK looked online for an update and told me that 14.0.1 was available. So I allowed it to downloaded that version, and it installed without any problem.
Is there some reason why the updater APK would show the older 14.0.1 and not the 14.1.0, and why I would be unable to update to 14.1.0 by manually loading the “sys_emerald-images-14.1.0+65f18f1.emerald.user_signed.zip” file?
14.1.0 is available as incremental on top of 14.0.1. The Updater would sometimes show your local installed version, just apply for any updates that appear.
The updater app notified me of a version 14.2 yesterday. Are you guys going to post an announcement about it with details of the changes made?
Usual security patches + fixes
Is it certified, will it pass play store integrity verification, will it work with ChatGPT?
While our builds meet all certification standards, a keybox security leak has forced Google to revoke keys for us and several other small OEMs impacted by the breach. This means emerald/zirconia builds currently won’t pass Play Integrity checks.
We’re working on a permanent solution through key rotation, and will ship an OTA update with a temporary fix soon that should pass BASIC for RCS & apps like ChatGPT. Thanks for understanding!
