Restoring Apple Silicon M1 Macs Leading to macOS Installation Errors

Apple couldn't predict people would need to restore their machine from scratch?
Give me a break!
at first i receive mac mini horrible slow till i bought imac , when my friend want to resell it i format it to yosemite . it freakin fast no slow. When install software in windows, apps polute registery ,dll everywhere till nobody know while macos polute file everywhere . Even you remove apps to dustbin you still have some orphane file not been remove with few generation version. So the best to prevent is to install latest apps.
They obviously didn't test this. Or worse, tested it and didn't care to fix it. Either way pretty big fail for essential functionality.
Can someone update this post later when Apple has released a fix? Thanks!
The sad part is even having to explain yourself. What kind of forum is this, where people question motives behind wanting to do a clean install?

Seems to be pretty thorough.

I guess it's Apple's new breast implant. 😂
I have read the link below and in the 11.0 recovery situation. Have everything I need except I cannot get it into DFU mode.
When you say you first need to go to the recovery selection screen first, what are the steps after that?

Thanks for that. After countless attempts to restore using Apple's instructions I found your site. Downloading the IPSW and restoring from that did the trick. Apple support had no answers. Now to figure out how to go to a case-sensitive filesystem without re-bricking it.....I also wrote an article specifically on booting Apple Silicon to DFU mode and how to restore via Apple Configurator 2.

Have you read it? There is literally no useable information on that page. Just weird diagrams. There are no instructions, no helpful link, nothing. Just a link that leads to another link which leads to Apple’s configurator help. Which I’ve tried, and doesn’t work.Did you see the below link from earlier in the thread here?

Just wait until you try Windows again. Apple isn't perfect by any means but Windows is a whole different level of pain (and I use both).
I was referring to restoring from an Intel-based Time Machine backup, not resetting from another machine.
Because I am a glutton for punishment (and still need to be able to use migration assistant from a case-sensitive Mac) I went back to erase and try again. This time I noticed another button when erasing "Macintosh HD". There is an option to erase the volume group (bottom left of the dialog when selecting the filesystem tyle). I used this option and the reinstall appears to be working as expected. Down to 4 minutes remaining when it would typically fail around 50 mins remaining.
Go into disk utility and erase Macintosh HD then select "erase volume group" and see if that helps. Worked for me.
He wrote a 2nd follow up article that details your use case - if you missed is post right below mine here it is again:
Restore macOS Firmware on an Apple Silicon Mac + Boot to DFU Mode
Detailed with screen shots even.
Geez, finally got into DFU. For those still struggling, boot into recovery by holding the power button during startup. Once at the recovery selection screen, press the power button 1 sec and then the other 3 keys for 10 sec. Let go of the 3 keys and then the power button 4-5 seconds after that. NOW, it looks like the mac is off. It's not. It should be in DFU mode. I kept thinking it was off which made sense since the power button was just held again. ugh 
. Wasted time. Just check the configurator to see if it shows up in DFU.

Hello everyone,
I just registered for this thread. At first: please apologize my english, I'm not a native speaker. And additionally I would like to point out my strong aversion against the people who complained against those people, who restored their new MacBook, just as @groundedUX mentioned previously.
I was very miserable about the condition of my recently purchased MacBook, as no method of getting Big Sur back on the Mac seemed to work. Though I don't own a second mac, so I was not able to test out the method with "Apple Configurator 2".
I don't know if Apple fixed the problem at that exact moment, but I found a solution that got my MacBook running again.
Since I was able to delete the volumes in the Startup Options -> Hard Disk Utility but not the complete SSD (constant error -69877), I became suspicious and logged into icloud.com with my Windows computer.
From there I selected "Find iPhone / Find My" -> "All devices" (above) -> "Macbook XYZ" -> "Delete Mac".
It then said that the MacBook will be automatically deleted the next time it is online.
I turned my Mac on and it was brought back to the startup options. I opened Safari, just to be sure that the mac connects to the internet. After that the MacBook actually deleted itself - after rebooting I had to select the system language again and in the hard disk utility only the volume "Untitled" was visible below the SSD instead of "Macintosh HD" and "Data".
After that, full of hope, I clicked on "Install MacOS Big Sur" - and indeed - the installation passed without any problems. I am very relieved.
Try it out, the Apple Chat couldn't help me at all (even wrongly recommended shortcuts for the MacBooks with Intel chips, which, as we now know, don't work with the M1-MacBook) and only could have given me an appointment for next week Wednesday.
Please let me know if that helped you.
