[Certified] Android 13.1.1 for Teracube 2e Zirconia (SN:2020)

[sayn]

Hi there,

after the good news above, I would also like to update my Zirconia (11.0.4) to the new version. But when I run the updater (copy zip from Win10 PC to internal Android downloads folder) I only get the download. Then I had to press OK to start the update and the progress window shows 0%. Then the phone screen goes black and the phone reboots. That means… always boots into 11.0.4. I tried this three times, now as a last chance I’m downloading the 13.0.3 version again. But I think that won’t work again.
Do you have any instructions for me to make the update work? If it is relevant - I am from Germany (2 SIMs from Telefonica are present in the phone, I have an SD card installed and the battery is charged to 70%, there is 20GB free in the internal memory. Is there an updater log file ?
Last thing. I tried to wipe the cache partition (as you write on here) beforehand to possibly avoid the factory reset problem described above. But I didn’t manage to get into the recovery mode. I was able to select the big recovery in the selection screen, but the phone didn’t boot into recovery mode. There was only a broken android robot with the error “no command”. I tried several times, but I had no success. Is my recovery mode defective? Can I check this in factory mode ore elsewhere? slight_smile:

No success on getting voice call functionality back, yet. I tried resetting the APN and restarting, but this just reverts to the AT&T default, not the Red Pocket third party network, so nothing works on it. There was still no VoLTE option in settings, either.

No luck either through Red Pocket customer service, tried getting an OTA (re-authorizing my SIM?) and triple-checking APN settings.

Any other ideas why the VoLTE functionality disappeared for me?

Thank you, anyone who is able to look into this.

Yesterday, I upgraded my phone from Android 11.0.4 to 13.0.3, which unfortunately required a factory reset due to corrupted data. I had fingerprint, PIN, and encryption enabled, along with more than 20 GB of free space. My phone has been running since 2020 without a factory reset until now. Setting up the device from scratch was quite frustrating, especially since I had to retrieve all the access codes for my banking app and other services.

After the upgrade, I noticed an issue: the network name now shows “Magenta-T-”, even though I am actually with the MVNO “HoT”. I am based in Austria and have only one SIM inserted.

Aside from this, Android 13.0.3 runs very smoothly and without any other issues on my device.

Upgraded from A13 Beta 2 without any issues. Thank you!

Anyone else having trouble with google play system does not update after updating from 11.0.4 to 13.0.3. Says June 1 2023 and there’s an update it downloads it reboot to install looks like it doing it but doesn’t. I tried 3 times.

[sayn]

After some trial and error and carefully reading the recovery mode instructions again, I’m now able to get into recovery. I also wiped the cache partition there.
But when I try to update to 13.0.3 the whole thing unfortunately still stops at 0% with a phone reboot.
Isn’t there any tip about that? Should I do an factory reset and try again?
btw: I have installed an additional root certificate on my phone, could this be the cause?

This may well be it.

Can you try from a factory-clean state?

[sayn]

Hello Saijin Naib,

thanks for answering. I tried to remove the certificate - but no sucess.

I then backed up all my data, removed the SIM cards and SD and performed a factory reset. After that I just entered WiFi to download the update again. That was done. But the updater now fails after downloading it and clicking OK to begin the update. At about 27-32% the phone restarts. Is there a way to manually install the update without using the updater in 11.0.4 directly in recovery mode? Or should I stay with 11.0.4 - because there is another bug on my phone?

[sayn]

I have now the 13.0.3 update ready on an fresh sd-card to start it in recovery mode with the option “Apply update from SD card”. (Because Im not firm in that ADB stuff.) But… Im unsure about my doing…

A last message for today. Sorry for all the text here, but without a phone is… without a phone.
Small side question: when the updater transfers the file, this is displayed in the notifications. But it ALWAYS says that version 11.0.4 is being uploaded. Is that correct or is my updater stuck on this version?

Thank you Saijin_Naib! This one work like a charm. After the reset to version 10, I was direktly updating to 13.0.4 … And this works also without any problems. Google restore also gave me the icon positions of all my apps. I did not expect that! Nice!
Since today morning 13.0.4 runs without any issues here! I have only two questions last:

1. Is it possible to get the battery charge cap back in Android 13? In my opinion, this extends the life of the battery. And since the phone already has such great long-term support, that would be really great.
2. Where can I find the option to save my camera images on the sd-card instead of internally in DCIM? Is that not possible in this appversion?

[Saijin_Naib]

Sweet!

1. I will let the devs know this feature is missed.
2. You may not be able to if the app is not designed for Storage Access Framework, which Google requires for newer Android OS apps to see the external storage. I personally use OpenCamera which can be enabled for SAF by toggling an option in the app’s (extensive) settings page.

[sayn]

Thanks for quick informations!

1. this is very nice! I hope they will have the time to implement it for us.
2. So i have to decide which app I prefer as camera. I know OpenCamera but I haven’t used it before. I’ll see, thx.

1. If rooted, you can use the ACC module to control your charging caps, including setting schedules and cooldown in the upper percentages and the like. Without being rooted, it’s a matter of waiting until a version is released with built-in support, which may be a while especially if that involves a core kernel shift again, as was needed when going from 11.0.3 to 11.0.4 which reverted most of the 11 enhancements to return DuraSpeed and caps back to native support. Note that core shift also required wiping most app data as many apps didn’t play nice with the transition. Hopefully if there is another core shift in 13, it’s smarter with time and upgrades.

Could you please share a screenshot of your APNs settings.

Apologies for the slow response.

I am about to trial US Mobile GSM since I never found a solution for losing voice calls over Red Pocket GSMA.

Here are my APN settings for Red Pocket:
