Hi first. I messed up... I managed to completely delete my /usr/ folder.
How do I reinstall Debian now?
I don't mean recover, I mean completely reinstall.

Hi. Do you have serial console access? If so, see issue #44.
You'll need to reinstall Debian 10, then upgrade to 11, then upgrade to 12. It'll take time but it's perfectly doable.

No idont have a seriel console access.
How can I reinstall Debian 10?

I don't think it's possible without serial console, after the partition resize.

ok i try it.

I'll edit the post to avoid spamming.

1.Recover via qnap live disk. Went without any problems
[~] # cat /proc/mtd
dev: size erasesize name
mtd0: 00080000 00010000 "U-Boot"
mtd1: 00200000 00010000 "Kernel"
mtd2: 00900000 00010000 "RootFS1"
mtd3: 00300000 00010000 "RootFS2"
mtd4: 00040000 00010000 "U-Boot Config"
mtd5: 00140000 00010000 "NAS Config"
under qnap fw.

Edit 19:11: Debian 10 is anstalled and running.
root@qnas:~# sudo ./qnap_mtd_resize.py --dry-run

[Check of the QNAP model and see if supported]
kirkwood-qnap: machine: QNAP TS419 family
DTB file: kirkwood-ts419-6282.dtb
Kernel has already been resized. Can't process further safely.

So upgrade to bookworm is currently in progress.

It took me all afternoon, but I was able to reinstall Debian without accessing the serial console.

Upgrade to bookworm is finished and Nas is purring like a kitten.
So that this doesn't happen to me again, I selected when installing that /, /var/, /tmp/ and /home/ are on spare partitions and I can backup the pure /.

It is, but you way just tweek the debian install script. It will be  - Follow https://github.com/amouiche/qnap_mtd_resize_for_bullseye/blob/master/Recovery.md  to re-intall the QNAP original firmware using the QNAP TFTP method - re-install debian 10  as usual. - you will not need to do the partitionning again, it will already be set. Just tell me what you experience, and we will update the recorvery documentation along. Arnaud

@amouiche
Thanks for your help, it worked perfectly.
Luckily I have to say, the serial to USB adapter I bought from Amazon doesn't fit the pins on the board of my TS-421, the plugs are too big...
