No Wifi After Update To 5.2.27 - I'm On Osx

Aug 28, 2013
Hi Forum!

Hopefully, someone good will show some mercy! I did upgrade to 5.2.27 - and yes, I did NOT read the guides carefully. Done this before, and got it all right then, but not this time.....
If there is a guide, or some good advice on how to upgrade the ROM from OSX, before or after Maverick, I'll be just so happy!!
