Ok so i had a leaked version of 5.0 from a while back on my tour. i plugged it into my mac today and it offered me a os update. So i just took it. It said failed about 75% through and not i get app error 523 message. and i know i need to delete some 3rd party app but DM wont recognize my BB at all except when it says waiting on device to start.
If you need quick help the search would have provided more information than you could possibly read. search for reviving a dead blackberry. Oh and you may want to use a PC for this since MAC has no software designed for this process.
