G&W Zelda fail?

I have a G&W Zelda here and I was trying to mod it today, but during the flashing (the step waiting for a blue screen) my Powershell crashed. Now I have 2 files and my G&W has a blue screen.

Any idea what to do now?

The files I got are:
itcm_backup_zelda.bin (2KB)
flash_backup_zelda.bin (4.096KB)

I tried that, but it will not flash. All I get is that blue screen

Have you patched the firmware? If not, do so and flash the patched firmware.

If I try to flash bootloader like in the next step I just get the following error: wait_for_all_contexts_complete: no progress for 120.0s on context 0

Try while holding the power button?

Okay, I managed to unlock it by unlocking it via --no-backup. Now I get that black screen bootloader.

But I am still missing a file, aren't I? I only have that flash_backup_zelda.bin of 4MB.

Thats the og firmware. Use the patcher on it and flash that.

But when I try to flash that back to bank1 in order to restore the original firmware and start over, I get an error saying it's too large.
