As long as you have a nand dump you can try asking deadlyfoez to fix it for you.That suks, Meh Wii! thanks anyways
the majority of this forum will vouch for DeadlyF , Reverse compatabilty , you mean has wii functionality , then yes it does , it is hackable also but i would tread very very carefully with a wiiu or vwii seeing as you managed to toast a regular wii with backup options , you fuck the vwii up then its gone .
If it flashes once that means no bootmii in boot2, you are completely out of luck.
Also, stop using Pimp My Wii. It is a horribly written application.
I have repaired well over 200 wii's and have never had a single complaint from anyone. And in case you don't believe me or the other people in this thread, there is also this DeadlyFoez Appreciation Thread that someone else made quite some time ago.
