Homebrew Bricked DSi LL - trying to fix it in hard way, need help

[Yokushiro]

Hello there! I bought very cheap DSi LL in good condition, but it dont work. What you need to know:
1) I have no connection to owner, so I cant ask him, what he did to console
2) I have no bakcups, no original SD card
3) Console says "an error has occurred" in Jap)
4) I dont know firmware version

So, i already try to fix it with Hard Mode, i already take nand dump from this console, also decrypt its CID and ID.

With HiyaCFW Helper I already restore files from that nand to sd folder (funny, its also restored some photos of old japanes man, maybe the owner), try put it to sd card, but its useless.

Error appears after power on.

I think its something wrong with unlanch, I trying to open nand with OSFMount, but it faild to open.

Maybe anyone can try to repair this nand file, if I give it to you? I want to try and ressurect this console, but I have no other ideas, how to do that))

Boot holding all the face buttons some of them should open unlaunch. Set it to autoboot to system menu and see if that works.

I cant boot to any menu, error start at the moment i push the power button.

I tray every button (and coombination A+B), but it dont work

Maybe I need spicific setting when I try to open it in OSFMount?

if you restored the nand. take out the sd card and see what happens.

Remember, I have no clear backup I try to fix it (restore) but nothing happens, with or without SD card...

Mybe someone can give me working backup from their DSi LL? It won't get any worse anyway, its already bricked )))
