I bricked my DSi while flashing a NAND backup (I tested it in No$ and it worked, (I also re-encrypted it) I was trying to flash it because Unlaunch wouldn't install so I did the manual method (Modifying a TMD file in the nand with the exploit) and in No$ it showed the splash screen and it didn't crash or throw errors, But while I Was flashing it FWtool stopped and said something along the lines of it couldn't read the SD card so I started it again, And it crashed at the same point and I tried it like 3 more times so I decided fuck it I'm just gonna re-copy the file back to the SD card, Maybe it's corrupt, I tried to turn the console back on and nothing happens, Is there any way I can try to recover it short of a hard mod? (I don't really care about my NAND as I backed it up right before I flashed it, So much as I do about the hardware, I don't really wanna buy another)

Edit: I don't think I have the skills to hardmod but I can't do anything else with it so it's worth a shot.
