First a have tested my UUDv3 by my self and it works GREAT!
Can boot into WAD Manager and boot BootMii IOS with it from RM.
You guys dont forget two importend things must be installed/patched that my or any other of the Unbrick discs can work: 1)
You need removed Diagnostic Disc Check* 2)
You will need a Trucha able IOS* The Diag Disc Check:
Is implented from Nintendo into the RM to hunt down Backup or Moddifyed Discīs.
How it works?
Well..factory discīs are pressed not like our self BURNED
discīs.There for without removed diag you need a "GOOD-DriveChip" to be able to Autoboot discs.Even if my discs are set to autoboot, older or low budged chips dont know what to do with the value "0" on the first place of ISO name in the image it self. The Trucha able IOS:
Sure you can still boot backups true the RM but if you alter the IMG than you need to resign with common-key.Resigned Discīs only work with the Trucha Bug.A IOS must be loaded to play/handle the game.Even with a modchip!!Sadly since FW 4.0/4.1 all trucha able IOSīs are gone.If you dont have patch them or have at least one cIOS installed to be call as disc driver than you cant boot a Modd disc.
And the bad thing on this so called "Drive Chips" are that they now can boot games from SD.Better sayed it is a "Drive Chip" to boot only from SD.But it cant execute a HB .elf/.dol?
I rember back onto the old good PS2 äera.Where real "Modchipīs" can execute HB .elfīs.But enought with talking here are two vids of UUDv3 booting via RM and used to boot into BootMii
FW is 4.1, Startpatch installed,Removed Diagnostic Disc Check,cIOS60 along with cIOS-COREv3.4 WITHOUT cIOS36 (becouse hbc use this IOS on this Wii, and if you delate this IOS than the new HBC from hackmii installer v0.4 will stand up on his Head
Here a very good troubleshooting about Wii Bricks from the SaveMii site itself:
