Depending on how you mess with the system menu, Priiloader can become unusable since it installs to the system menu. If, for example, you install a system menu in conjunction with an IOS stub for that system menu, Priiloader gets erased because you've overwritten the system menu, the system menu can't boot, and you can't save your Wii without bootmii as boot2.


By default, bootmii as boot2 is set to launch automatically at boot with the proper easy-to-obtain files on your SD card. The reset button is irrelevant.
priiloader saved me from banner brick luckily so the myth is priiloader install to system menu the truth is actully it doesnt priiloader overwrites boot2 (if it can) otherwise it will overwrite boot1

Priiloader can save one from a banner brick because whatever caused the banner brick hasn't irreparably harmed the system menu and Priiloader, but Priiloader does indeed install to the system menu. A banner brick is an example of a kind of brick Priiloader can save you from. Priiloader does not overwrite boot2, and it is impossible to overwrite boot1. I see what ScarletDreamz was saying about you misleading people. If you don't know how something works, don't pretend like you do.

actully theres a way to stop boot1 from protecting boot2

why do you need to have a nand backup on priiloader? lol

The boot's vary and have different ways to boot through to Bootmii. Priiloader is a way to acsess Bootmii if you cannot launch it with Bootmii as an IOS. Boot2 uses the same method but by default if you hold reset you will be taken to the Bootmii menu, you can still use the alternative method if you don't want to be directed into Bootmii if you have Boot2 you can still use Priiloader if you want, however it's not required.

The boot's all have pro's and con's but 99.9% of the time boot2 is more superior than Bootmii IOS since Bootmii IOS can only recover from bricks like "Theme Error", or "Semi Brick." Bricks. Where as Boot2 can mostly recover from almost any type of brick as long as boot2 is present in the Wii System.

The main point is the overall best brick protection is boot2, but that doesn't mean you shouldn't use boot1, or boot0 if someone says you can't (Becuase you should have the right.) But it's more dangerous to install it as a boot0, boot1

You should always keep a back up of your NAND as well. Becuase if you ever get a brick you will be prepared for it,

*Save wii from banner & other kind of bricks that aren't ios/boot2/nand corruption related*

Depending on how you mess with the system menu, Priiloader can become unusable since it installs to the system menu. If, for example, you install a system menu in conjunction with an IOS stub for that system menu, Priiloader gets erased because you've overwritten the system menu, the system menu can't boot, and you can't save your Wii without bootmii as boot2.
By default, bootmii as boot2 is set to launch automatically at boot with the proper easy-to-obtain files on your SD card. The reset button is irrelevant.

This is the part i didnt remember, that bootmii launched with just the SD files present C:

Priiloader does not install as boot2, it install iself on a section of the boot sequence.

*
Priiloader places itself in boot sequence before the system menu. By this priiloader has the ability to:
  • Patch memory just like StartPatch or Preloader. hacks_hash.ini should be on the sd in sd:/apps/priiloader (only once, they get copied to NAND) and can be found here.
  • Save wii from banner & other kind of bricks that aren't ios/boot2/nand corruption related
  • Start something else than system menu on power up (a dol file, bootmii, homebrew channel)

As part of the boot process, boot0 will decrypt and hash boot1, and then compare it to a SHA1 hash stored in on-die OTP memory; if they do not match, then boot1 will not be executed. This means that any attempt to modify boot1 on a Wii will cause it to fail to boot.

Priiloader places itself in boot sequence before the system menu.
Specifically, Priiloader installs itself to the system menu and, when the system menu is launched by boot2, Priiloader launches itself first.

Indeed, thats why if you press the reset button to launch priiloader, you will see the blue light flashing 2 times telling that bootmii is placed inside boot2, then priiloader will load. as a Pre-Menu option.

i need some lifesavers for wii that saves you from ios/boot2/nand related courruption (not bootmii i cant install as boot2)
Without having the option of bootmii as boot2, then you can only install it as IOS, have priiloader, and have a full nand back up.

^This is all you can do without bootmii as boot2. I highly recommend you do this, @TheTurkGamer, because based on the information you've provided, you are likely to brick your Wii.

You cant. if you somehow still got access to priiloader, and somehow you can launch a .dol try launching MMM and install the system menu, or if you can launch HBC go to boot botmii.

If you can still launch Bootmii inside the HBC via Priiloader, thats gonna be your chance, if the nand its likely more corrupted, then there's 0 way of doing this. and as @Lacius said, based on the information you've provided, you are likely to brick your Wii.

Install Priiloader, and bootmii as IOS, backup your nand, and then, Please, dont install ANYTHING or move the CIOS/IOS onr you wii, leave it like it is, don't mess with channels nor wads, nor anything. dont install, move or apply anything else. dont touch themes, dont touch ticket files, tmd, cert, NOTHING, no CIOS, no custom Anything, just load every game you got from the USB/SD using a loader, and that's it.

no it had boot2 maybe low level brick screwed all boot funcions (boot0 boot1 and boot2)

No. Boot0 is in the GPU and boot1 is the first block of NAND. Neither can be written to. You couldn't possibly have installed boot2 and been unable to access it.

If boot1 was writable Nintendo would have patched the old consoles to make them BootMii resistant.

Priiloader replaces the system menu's ".app" file in NAND and runs it if you don't hold down reset while the console is starting. It moves the default system menu .app file to a different filename.
