So I was trying to go back to 4.1 to prevent bricks and have bootmii as my boot2, but in the process I kinda bricked myself (ironic, huh?) The Wii has a green LED when I hit power and the TV gets a signal, but there is no display from the Wii. I have a NAND backup, but nothing for my boot2 since I was on 4.3. Is there any way to fix this? I don't have priiloader installed or bootmii to open on boot so I'm wondering if there's any fix.
Also would a savemii work or no? I don't see the health and safety screen so idk if it will and wanted to ask people who knew what they were doing (unlike me)
First of all. If your Wii isn't compatible with BootMii as boot2, downgrading is not going to help that. They fixed the boot1 vulnerability that allowed BootMii to work, and we can't change boot1, once it's written at the factory it can't be changed.
So downgrading was rather pointless and if you had done more research beforehand you could have realized that and avoided downgrading altogether.
I am guessing you forgot to install the correct IOS for system menu 4.1? There are software unbricking methods for certain kinds of bricks, but to my knowledge they require the system menu being intact along with the correct IOS, so you're out of luck there.
The #1 thing to always remember when messing with the system menu and system menu IOS is that different system menus require different IOS and if you delete either of them or install a different system menu without installing the corresponding IOS it's a guaranteed brick. I don't think Priiloader would have helped, I believe that also relies on the system menu IOS (since it essentially replaces the system menu)
Your only option is hardware flashing. Back in the day I would have referred you to
@DeadlyFoez, he was the #1 go to man for such things with many many (hundreds?) successful unbricks under his belt.
But, these days, a used Wii barely costs anything. It's probably going to be cheaper for you to simply buy one second hand than try to fix the one you have. Even the hardware needed for flashing the NAND is rather pricy, and that assumes you have the skill set to solder it yourself or you know someone that does and are willing to do it for free.
If you really want to fix what you have, I suggest buying a working mainboard and installing it. It won't be much cheaper than just buying a second hand Wii, and it's far more work, but you get the satisfaction of taking what's broken and returning it to working condition (as long as you don't mess anything up such as damaging any of the fragile ribbon cables and their connectors). No soldering should be required.
I've taken a Wii apart before, it's not particularly hard (just need a triwing screwdriver of the right size, some guide online on how to take it apart, and patience), but I never disassembled it fully, so I didn't have to unscrew and unplug every single thing as you likely would have to when replacing the mainboard. Still, I think it's one of the easier consoles to disassemble. If you're up for the challenge it could be a fun project.
Even if you do that it would essentially be a different console so you would lose your saves. You can extract what you have in the NAND backup using ShowMiiNAND (part of ShowMiiWads) but anything newer than what is there is lost unless you go the hardware flashing route, and back up the bricked NAND before flashing to extract the save files from it later on.
