I flashed the wrong nand backup

[Doodka]

Hello, today I mixed up two v2 and flashed rawnand using nxnandmanager. I haven't started work on this console yet, so I don't have a dump of this console. As I understand it, I destroyed prodinfo, safe, user, system, etc.
all I have left are backups for boot0/1, prod and title keys, kfuses, fuses_array and cached
I used the video "sthetix" about unbricking, but now the console just shows the nintendo switch logo
what recovery options do I have?

Only way is to desolder the eMMC and reprogram it using a programmer that supports eMMC chips. RCM is not supported on V2 models from what I could tell.

man, this is too radical. Firstly, v2 emmc can be connected via a connector without soldering. Secondly, I still have the modchip and it allows me to boot into hekate. with its help I recovered dump from scratch.

As it turned out, the problem was the inconsistency of my attempts, I mistakenly flashed unencrypted prodinfo via microsd, and the next attempts I flashed via usb.
It turned out that you cannot flash an encrypted partition over an unencrypted one via USB. I flashed it via microSD and now the console starts up. Unfortunately I don't have the original prodinfo, so I can't connect to Nintendo servers

Should label your NAND backup correctly, so you don't use the wrong NAND with the wrong unit.

I had two switches lying next to each other, I just mixed them up and started flashing them through a PC. By the time I realized my mistake, it had already started flashing the user section. PC Told me that the keys in the program and on the switch are different, but I didn’t pay attention to this, I thought it was a software error
