first, it's forbidden to share files from nintendo.
second, 22.app could be anything.
it's like asking for "data.bin", please I need "data.bin" ! yeah, but which program? or application ? which version ? which content or size etc.
anyway, we can't share it because it's copyrighted, and it's not even needed to fix your vWii.
what you need is the system menu files, which priiloader replaced.
you probably can find it using NUSD for vWii, extract it to get 00000023.app, then access your MLC and replace the file by ftp.
but it's even easier, priiloader didn't delete your system menu, it made a copy and renamed it to 10000023.app, so you don't even need to get a file from anyone, you already have a copy on your SLCMPT (the vWii NAND), it's in system menu folder, just rename it. be sure the rights are set correctly too (executable, etc.)
resume:
use CBHC or Haxchi, and ftpiiu_everywhere.
connect to your SLCMTTP using a FTP client on your computer.
1. delete /title/00000001/00000002/00000023.app,
2 rename 10000023.app to 00000023.app
hint:
make a copy of everything before deleting anything.
even better, make a full nand dump before attempting any system edition, for people who like to mess things randomly and delete wrong files they shouldn't touch ...
note:
this is only a deduction based on how priiloader is working (renaming the system menu and replace itself with the same name to be launched first).
I don't remember why priiloader didn't work and it bricked (is the .app ancast'd ?)
if someone has any objection, or another way to fix (other than the 2 provided solutions), please be sure to comment. the vWii is already full bricked and not booting anyway.
