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?

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?

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…

If it broke when you rooted, I’d probably revert back and see if that fixes it. Just repeat with the bootloader, fastboot flash the original unpatched boot, and back to system. If that fixes it, then I’d probably try a different version of Magisk or whatever rooting solution you’re using.
Kitsune Magisk was great for hiding but terrible in that it only works for elevating apps on main storage, not the sdcard, and it had a hiatus from February to July. Still the version that had the best compatibility for avoiding detection though.
Alpha Magisk is good if you don’t mind changelogs in Chinese.
Canary Magisk is good if you want the most working official branch.
Stable Magisk is good if you plan on ignoring updates for months.

How to extract the original boot from the payload.bin though? Magisk does extract it, but will patch it right away. Thanks again for your help!

Oh, I’d just take the update zip, whether from post 1 or from your /data/teracube_updates folder on your phone, open it with your preferred file utility, and extract boot.img from there. 
Should get you a clean boot image as well as providing another chance for a “This download really wasn’t corrupted, right?” check.

I have, it made no difference unfortunately. I did find a program to extract the boot.img with ( GitHub - tobyxdd/android-ota-payload-extractor: A fast & natively cross-platform Android OTA payload extractor written in Go ), because that file is contained in the payload.bin file these days (older firmware still has it in the regular zip file). With that, i was able to properly root my phone with the 13.0.4+5ae415b build installed (security patch 5th of june 2024).
It’s now working, I’m weary to update it again…

The update proceeded successfully until the first restart. I had to factory reset my phone for it to complete the update. After that the phone restarted successfully, but all my data on the phone was wiped.

Sorry for the frustration, but there are cases where this might happen.
The team is working to ensure this does not happen on future final releases, as this came up during this past round of Betas.
It wiped all my saved passwords upon doing the update.
Downloaded apps and files remained.
Additionally, I was having major issues that were mentioned in a post about an update earlier this year. But even after updating to the new 13 version they are still occuring.
