Can you complete DFU?

Hi.
Yes, I completed DFU restore without errors several times.
When instaling new Os, SSD is not shown

At least T2 partition is in good state, if DFU was completed.
Check if any error pops up starting in diagnostic mode.
What happens if you try to put the machine in target disk mode?

Hi,
No errors appear on diagnose mode.
I don't have another Mac that I can use the Target Disk Mode, but when I start it in target disk mode, I get the thunderbolt logo at the screen.
When I try to boot from an USB disk, I can see the USB disk, chose the macOS version that I want to boot, but them nothing happens until I get the internet recovery menu.
When I try to do the recovery, the all process starts, but I get an error at the end.

You can use an USB-C hub to connect it to older MacBook.

Hi,
I'm using my Mac to conect it (it is a Apple Silicon M1 Pro), and I get this message (I'm not sure if I'm doing this correctly, cause is my first one).

Looks like SSD is detected.
Before booting through USB, go to Internet recovery and change security settings; to allow USB boot.

It doesn't give me that possibility. As soon I chose the wireless network, it starts the recovering process immediately. At the end of the process, it gives an error.
I can't chose anything...

Check in boot menu.
Top tools bar doesn't appear?
Try to test the SSD in target disk mode from the other machine.

In boot menu I can only chose de boot disk, but only shows usb disks. No internal disk.
No menu bar appears anywhere.
I already done that, and even formatted the disk successfully

Internal SSD doesn't appear on boot menu, if is not bootable.
Try Internet Recovery using ethernet connection, instead of wireless.
Also start with Shift+Option+Command+R, to reinstall original macOS version.

Same result with Internet Recovery using eth, and Shift+Option+Command+R .
Any idea?

You can't reach Disk Utilities from Internet Recovery?

Hi,
No I can't. As soon as the internet recovery globe is shown, it starts the process, and after a few minutes (when the loading bar reaches the end) it gives an error.
I have no chance to access Disk Utilities.

But you can test the SSD in target disk mode from other Mac and no errors?
Try to install new macOS from other Mac into target SSD; lets see if accepts.

Hi,
Yes, I can't test the disk in target disk mode from other Mac, with no errors, but when I try to install macOS on that disk I get an error:
"it is not possible to install in this volume, because the Mac is in target disk mode"
