[Certified] Android 13.2.1 for Teracube 2e Emerald (SN:2021)

[gadet]

After I installed the update to Android 13, I can send/receive texts and use mobile data, but I cannot make any calls. When I dial, the phone is silent for a few moments before going to “Call Ended.” H2OWireless is my mobile service, and the below APN settings were working before the update (when my phone still had Android 11). The default H2O Wireless APN (with PRODATA in the APN field) does NOT work.

I have already tried the basic troubleshooting steps, including: toggling on/off Airplane mode, removing/re-inserting the SIM card, toggling off/on “Use SIM,” clearing data and cache for the the Phone app.

Did you try resetting the apn settings after 11.0.4?

Hi,

I updated to Emerald 13.0.4 on 6/15 and it knocked out my data on ATT. I can still make phone calls and use SMS. I followed similar steps as @gadet and also reset apn settings but no dice. I’m new to this so I’m not sure what to look for.

I can also attest to battery speeds seemingly draining faster. Though I’ve already been needing to replace it, and although it has been lasting longer over the weekend albeit due to not having data, I’ve noticed that it drains quicker now while using most apps. Also, since the update, charging stops at about 90%-95% whereas before it charged to 100%

I’ve also been experiencing process crashes after soft resets. Messages like " Quickstep isn’t responding" and “Process system isn’t responding” while fiddling with system settings.

Welcome!

Sorry for the trouble.

Are you in a position to backup the phone and re-do the flash so you have a clean slate?

[gadet]

Yes, after the update to Android 13, I changed the APN settings to exactly what I posted above. When those didn’t work, I tried resetting the APN to the default settings and tried every single one of the defaults (including the H2O Wireless PRODATA one), and none of them worked.

[gadet]

Is that the same as doing the Reset option of "Erase all data (factory reset)? If so, I will not be in a position to do this until this Friday, June 21.

All good so far.

[Saijin_Naib]

That would be my first recommendation to do, yes.

[Sahil_Sonar]

We have indentified the issue, should issue a hotfix soon!

[gadet]

Do you mean for being able to make calls using H2O Wireless? If so, then thank you so, so much! I did a factory reset, and I still cannot make calls (but I can send and receive texts).

How do I get the hotfix?

[Sahil_Sonar]

It has been rolled out as staging and you should see it within a week! I’ll update the forum post for new link as well.

[Sahil_Sonar]

Hello users, we have issued a hotfix to address issues faced on AT&T carrier and users on 13.0.4+dc21fc3 should see the update via OTA within a week. If you want to try early you can check the updated post for build 13.0.4+5ae415b. Kindly report back to us with your APN’s settings MCC and MNC if you are still facing the issue after the hotfix. Thank you for patience!

My phone is running 13.0.5+2f26114 but still cannot make calls. APN settings have been checked by the carrier. MCC is 310 and MNC is 410.

I installed the latest update and then did a factory reset. Still cannot make or receive phone calls, but can send and receive text messages and use mobile data. Here are the APN settings I am using:

How to contact Teracube support

Hi @James_Krehbiel , Our T2e Android 13 update does not support AT&T. If you are using AT&T, then please revert to the earlier Android build using these steps - [Teracube 2e] Instructions to Install Factory Software and to Reset Here is the list of supported carriers

[Sahil_Sonar]

New update with charge limit is live on Updater. We are working on AT&T issue, users facing issue can rollback to Android 11.

[Sharad]

Users experiencing cellular connectivity issues on Android 13, please do the following:

1. Check Settings > System > Updater for any updates. Install any new updates.

2. Reset your APN settings at Settings > Network & internet > SIMs > Access point names > 3-dot > Reset to default.

I’ve updated without problems through the auto updater to 13.0.5+ (security patch level 5th of July). Thanks! Seems to be working smoothly, no problems with cellular connectivity (thus far).

Root access is gone now though, is there a way to (easily) root the phone again?

[Maymne]

Beginning to get incredibly frustrated with the lack of live wallpaper support

Of note, it should only take 15 minutes or less to successfully root your phone, after you’ve done the prep work once. Current process, from scratch: Download the update file for your current build, if you don’t have it already. Extract the boot.img from it Copy that to your phone Install Magisk - I prefer Canary but that’s because I like being able to pass Certification and still use an official branch Open Magisk and patch the boot.img you copied over - do not try to patch vb or anything els…

Anytime you do a new build, it’ll remove root since it’s a new bootloader file. On a positive note, after you get used to the re-root process, it’s less than five minutes work to extract the boot.img from your update zip, patch it using your Magisk, and then it’s just copying to your computer and doing a quick flash. Should be less than 15 minutes total including the reboots.
Note that due to how Google does the current unlocked bootloader warning in Android 13, it’ll add 2 minutes to each reboot and at least on Zirconia, it adds an extra 3 minutes while it has a reboot timeout for a total of 7 minutes (two sets of 2 minute bootloader warnings, one 3 minute reboot timeout) additional waiting on each reboot while rooted. This did not happen on 13.0.4, but it’s still worth going to 13.0.5 for a Google app that doesn’t have broken voice search, integrated battery limiter, updated APN functionality, etc.

Thanks for that, was easy enough to do! I’ve got root again Unfortunately now i’m experiencing connectivity problems. Can’t make calls or use wi-fi. Mobile ethernet does seem to work, if i activate it manually…

I’m not on AT&T, based in Europe…
