Great work George,
Firstly, what did you flash with updater.exe? Was it the full 3xx0 fw or a cure fw? Don't worry about the missing audio files or logo yet, let's just take a step at a time. On the About page, what Software Version is showing?
It might be AM in the land of Ol' Glory, but it's late PM downunder. I'm gonna be catching some z's soon but if i don't reply there are plenty of others here more skilled than me: i.e. Loly, Angelo, dasil et al.
BTW, I've not heard of anyone having a problem with the sd card method previously. I've only used it relatively recently but compared to the old methods it's like falling off a log. If you want to stick to the updater.exe/rgn method that's fine, but i can't help thinking that there must have been something wrong with your files when you tried to do the sd method or the process was interrupted somehow.
Dear Rog [aka Speedy Gonzales], NP. I undeleted one of them... we're both toooo efficient ... LOL!
Note by MOD: sorry,Neil... I tried to undelete post but not works (sob!!) ....now works
