Why is there the instructions to enable USB debugging and approve the connection when upgrading from Android 11?

Probably so that if thereâs a problem, you can actually gather and pass along logs so that if itâs a fixable issue rather than something intrinsic in the data, they can actually try to patch it out for future builds?

Youâll need to manually download and install the update as it is not available OTA for Android 11 and earlier due to a possible data migration bug causing a reset:

I ran into the same corruption issue:
âCanât load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device.â
I followed all the steps with enabling usb debugging and adb devices prior to the upgrade process, and confirmed that my computer connected sucessfully to my phone via adb.
Unfortunately, once my phone was at that âCanât load Android systemâ screen, it was no longer connected, and following the instructions in the OP to choose âTry Againâ and do adb logcat > logs.txt doesnât do anything. adb just sits there saying - waiting for device - with no further output. Note that I first did those two steps in the order listed (first selecting âTry Againâ, and then starting adb logcat > logs.txt), and when that did nothing I tried the other way around, leaving the - waiting for device - message sitting and waiting while I selected âTry Againâ on my phone. In both cases, the phone just ends up back at the corruption screen and never connects to adb (and thus no logs are output).

We are not able to reproduce it in our testing. We did ask users to help us by providing logs, but we have yet to receive any.
My above experience makes me think that the reason you arenât receiving any logs from people is because the instructions provided arenât working to get the logs. Are the listed steps perhaps incomplete?
Were you able to see the bootanimation after âTry againâ?
A new security upgrade is available! Check for Updates in Updater (Please note it rolls out gradually and might take days before its available to update for everyone) or apply manually from the main post.
Note for Zirconia Android 10/11 users: New 11.0.5 is available via OTA, Apply same before upgrading to Android 13.

Do we think that the 11.0.5 might help avoid the factory reset on upgrades, or is it just providing a security update so that people who prefer to stay there feel less sad about their choice to avoid the updates?
11.0.5 doesnât bring any new security updates. Its an intermediate build to be updated to before upgrading to Android 13. We are moving everyone to Android 13 due to security risks in Android 11 firmware.

Just tried to update and got corrupted and my phone is out of commission until I can get some help. I am low tech proficiency (though not an idiot) and donât know what to do and donât want to lose my data. I see some info above about this issue with the new update but honestly am not going to read a yearâs worth of comments to figure out what to do to recover my phone and not have this happen again. Please someone advise. Iâm honestly tired of teracube being so user unfriendly. Unfortunately I will not buy again since it is getting old and failing anyway and itâs almost time for a new phone. Really wish there was a way to be sustainable and responsible and not have to more or less be a developer.

You just tried to update from what prior version to what upgrade version, and what state is your phone currently in?
Without at least that information, nobody will be able to advise more.
I was on some version of Android 11. I vaguely remember it saying the last time it was updated was in May, but I commented on this same thread in June trying to figure out the update that was available then (bc it was only available from this forum via a download, didnât come up automatically in the updater) and waited bc of all the corruption issues it sounded like were happening and was told to wait bc they were working on it. I donât know what I was updating to, it popped up in my updater on 12/27/24. Iâm assuming this 13 version that this thread about considering there was a comment that new security patches had been added through December. I thought it had already updated since I started the process within a day but apparently not as it prompted me to install the same update today. I didnât even remember anything about all these corruption issues as I rarely check this forum and we donât get email notification or etc. about available updates. Not sure how to provide further details when my phone is currently inaccessible. Apologies for the cold language, but hopefully you can understand the lay personâs frustration with all this.
My phone is stuck on the black screen of death with multi colored text:
âAndroid Recovery
Teracube/Teracube_2e/Teracube_2e
13/TQ3A.230805.001.B1/t0pr4emerniabsp
user/release-keys
Use volume up/down and power.
Canât load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device.â
The only two options are âTry againâ and âFactory data resetâ
I have used the âtry againâ option at least 5 times and continue to get the same screen

Its expected to require a factory reset while upgrading from A11 to A13. The new Updater in 11.0.5 also prompts backuping the data before upgrading so does the post.
This is not helpful. It cannot âbe expectedâ unless the Updater says âthis will happen.â And again, every user cannot be expected to know the entire contents of this forum. (For example my 67 y/o mother also uses a teracube 2e, does not know this forum even exists, and if she installs this update and sees the reset screen, she will probably think the phone is broken completely.) Any update recommends backing up in case of emergency, and again as far as a low tech user like myself has been able, I do have things backed up. But I honestly donât know how to even recover that or have faith that I can get everything back to the way it was before. Which is why I am here asking for help to recover and access what may even be backed up or not.
Helpful responses on where to go from here or go back and start over to prevent this from happening again are appreciated.

At the point itâs currently at, if you were signed into Googleâs backup service, you likely wonât lose much besides the time spent trying not to do the only option remaining. Youâll need to factory reset to move on, though itâs up to you whether to accept v13 (which is better in a lot of ways) or use SPFlash to go back to 10.
If you sign in to Google as part of the post-reset setup process and let it finish installing and restoring data before trying to use the phone or doing additional reboots, many of the apps should restore their data.
After updating to v13, the only time I had it trigger the corrupted data/factory reset required afterwards is when I tried to avoid it by disabling fingerprints and the screen lock. Try to avoid disabling those since that does make it always corrupt itself; just allow it to run same major OTAs normally and that should be fine.
Thanks Maymne, is there any point or further information about the adb stuff mentioned above? We tried plugging into several different laptops today to attempt or see if we could transfer something but nothing ever happened. Not sure where I would even type in the instructions given. Or should I just accept the reset and see what happens?
Dear Teracube Team,
how cool is it that we are getting these updates now on a regular basis!! Thank you Teracube team! Great to see how you devoted yourself to stick to this task after so many setbacks and obstacles (mainly by Google I suppose).
Just wanted to point out these efforts, cause this is rare to be seen these days.
Cheers from Germany,
Frank
BTW: OTA update from 13.1.0 went smoothly, no issues!

The adb logcat stuff is trying to get info about how itâs failed so that maybe someday upgrades from 11 to 13 can happen without the factory reset. It wonât help you recover without wiping, unfortunately. Even flashing 10 or 11 back wonât recover without the wipe. Sorry.
It seems I was somewhat successful in restoring from backup after a reset, but there are odd holes. For example Messages only restored images, not actual texts; none of my previous files/downloads/screenshots etc. are in the âFiles by Googleâ app, some device settings including in Chrome werenât saved, and many app settings and logins are off too. Iâm thankful for what has been restored, but it would really be nice to get the above back as well. I will probably avoid future major updates on my teracube/get a different phone soon considering this major setback and risk. Please let me know if you have any ideas.
