3 months ago, I got a Nokia 5800XM from a friend of mine, cause my own phone was demaged. It was a very nice phone. But 2.5 ago after I updated the firmware, says my phone: "Phone start-up failed. Please contact retailer.".
I've been to the retailer, but they said it's too difficult for them. I'm also been to a Nokia Care Point, and they said that a new 5800 was cheaper than to repair him.
The death vulcan grip/hard reset doesn't work. I tried it 30 times.
How can I fix this? I really want to use him. Another firmware is ok.
Bit surprising if you really got such responce from Nokia Care..because it MIGHT have just required firmware flashing which certainly will cost nowhere around the cost of new phone.. If possible, try another Nokia Care..
