Is there an update for teracube 2e zirconia from Android 11 to something more current in EASY to follow instructions?

back in Oct 2024 I asked this same thing and someone responded with a good example of NOT EASY to follow or understand instruction for someone like me. I believe in right to repair. I believe electronics should last. I care about the environment- but I just cant follow all the 'terms".
The reply mentioned ‘SN’ and to me that means tin.
The reply mentions ‘…read the differences here carefully and flash accordingly.’ …um, I’m too prude to do any kind of flashing…i’ll keep my clothes on thank you very much. The reply mentions “…but as always, ensure your critical data are backed up before you do an operating system upgrade.” WHAT?? I have no idea what is ‘critcal data’ or how I would know if I backed it up!
I have spent too long reading stuff in here…am so lost.
someone was asked ‘what update’ they did…and something about sharing logs… I just got ‘new update available’ on my phone and it doesn’t say what it wants to update- how would I know? and ‘logs’- I say leave those trees be- we need more trees!
If anyone is KIND enough to assist in Easy to Understand instructions- that is who I wish would respond.

Maybe this is to update to Android 13- it sure doesn’t say.
is this for Android 13? Is it now easy to update? Are all those problems gone now?
My teracube 2e is zirconia. It has android 11.
You will confuse me if you reply with information about the other teracube 2e- so please don’t.
I would appreciate ‘current’ information - so please do not reply with something that was in here before January 2025. I won’t feel it is relevant to what is MOST current.
I do not have a back up phone.

Since it says they’re the update, you can click on that to get to the current version, but when you update your phone, it will almost certainly reset all the data. Since you say you don’t have a second phone, but you also aren’t following the tech talk, I’d recommend having any important phone numbers written down before you try to update the phone in case they don’t come back afterwards.
After you update the phone, it will go through the new phone setup process. When you sign back into your Google account, it will ask you whether you want it to restore the applications and contacts, and you probably want to say yes. Then it will take a while - probably a few hours - to finish copying back stuff. Don’t try to use the phone during that time, because it will make things go weird. The phone will tell you in the notifications when it’s done and you can start trying to use the phone again.
