Think twice before doing an erase/reinstall on your M1

Nope, I erased those separately, via Disc util tool from recovery options screen. First the Macintosh HD and then DATA partition. Didn't touch "erase volume group"
I removed the computer from my iCloud before following the steps in post #26.
I'm all set now. Fresh install. Didn't have to, but wanted to learn. Thanks to you here I got it to work.
No but it will be my next re-install method
I've re-installed 2 x M1 macs 5 times with 3 different methods - all without problems so far
This method is the next on my list.
As far as I can tell people using DU tend to delete Macintosh HD and sometimes the Data volumes. It is my theory that this is not enough. There are more volumes that also need deleting.
"erase mac" in the recovery environment and "erase volume group" in DU and erasing the Apple SSD in DU all do this (or so it is my belief).
And I suspect Apple Configurator 2 does this too.
I'll find out when I try it
Again, I'm glad to hear that you're up and running again.
The Apple guide that I linked you to said to erase the volume group, not the seperate volumes and I suspect this is why you had the error you had.
Yes it does and not everybody has another mac capable of running it (or another mac at all)
I’ve got my included USB-C cable & charging brick plugged into the other Thunderbolt port. It’s still chugging along.
I actually do have a MacBook (i9 16 GB / 1 TB) Haven't started it since I got the miniYes it does and not everybody has another mac capable of running it (or another mac at all)
Going to sell it.
Lol, I kept my 2012 rMBP so I could use Apple Configurator with itI actually do have a MacBook (i9 16 GB / 1 TB) Haven't started it since I got the mini
but that's not worth what yours is!Those instructions did not ever work for me. Infact nothing in Recovery would work for me. The OS would install, but it never booted into the desktop.
Step one on this page was the only thing that worked for me;
Making an M1 External Boot SSD in 20 Minutes...
Preface: I designed this process for making an external bootable Big Sur SSD. For installing Big Sur on a internal SSD I recommend using the Configurator 2 app along with a USB-C charging cable (standard USB-C and Thunderbolt 3 cables are not supported). Lately I’ve had so many problems trying...

I just did the Configurator 2 for 11.2.3 and it was done in 13 minutes (including downloading the OS).
The instructions I followed said, "Select your startup disk on the left, then click Erase." Those instructions are linked on the first post of this thread. The new instructions you linked are much clearer. I don't see why they would leave the old instructions up. As long as those instructions are out there, people will probably continue to make the same mistake I made. For people in that state (having erased HD and Data), the instructions in post #26 are valid.
That’s awesome! This is seriously the way to go. At least with the M1 Macs. I’ve still got a couple hours for the Time Machine restore to finish up. I used to just set it and leave it overnight and hope it was finished in the morning.
Yes, fair enough.
Unfortunately once they're on the web they can stay there for a long time on google searches.
The original Apple instructions did say that and that is where the mistakes are first made, I believe.
We're now in the position of having more than one recovery method, which is nice to know
We will get spoiled with this new method. In the past, I would just update as usual. I have decided to do the Configurator 2 with each release. That way, if there is a bug with the OS, I will know it wasn't acquired from doing updates on top of each other. And if I have a problem with a third party app, it will be a little easier to track down the cause, versus having an OS that has updates on top of updates. This might seem overkill but, hopefully, it will help with the troubleshooting when needed.
If I understand how these things work, the older instructions will be more prominently displayed than the new in search results.
Good question!
It looks like they've made a start.
Maybe it had to change because of the new architecture and/or new disk set up.
No you need a second mac capable of running the later versions of Apple Confidurator 2.
It's also possible to re-install without using DFU but that's what I keep investigating
I'll try Apple's latest instructions in a few days and see if they work out for me.
I'm not waiting a few days to try it.
I'm doing a backup now and I'll try these new Apple instructions in half an hour or so.

I did both, external and internal (Mac mini)
I recommend using Configurator 2 only for internal.
