Self bricked wii

Hello,
I have some big problems with my WII. So on start, my WII is first from I think 2005-2006 production, I soft modded it and do nothing to now (when my guitar hero not work). So I decide to make update with Pimp my Wii.

Of course I don't make any backup, before started all process....

After Pimp my Wii finish all updates, console restart, and started with my preloader v0.30.

But when I want to start "system menu" says me : es_diverify failed
When I try to start Homebrew Channel also put me error : Error autobooting HBC. maybe title not installed?


So I can't start anything, on this forum I found short guide, with these steps:
Download system menu 4.1u wad
Download ios60patched.wad
Place both wads in sd:\wads
Place wadmanager's boot.dol in the root of your sd-card
load preloader
click load/install
load wadmanager
use ios249
1st- install patched ios60
2nd- install system menu v449
then reinstall preloader


I have 4.2u system manu, but I want try with 4.1u and ios60...

When I finally start Wad Manager 1.7, when open program welcome screen, my WII remote switch off, and it wont start... (I don't know, freezing?).
When I want sync with WII nothing happen.

I don't know what I should do now.

Thanks for help.
Regards
