one thing mentioned earier in this thread, and one thing only, helped starting it up - plug it into PC, wait till PC sees it, troubleshoot through Devices and Printers...
I am fully devoted to Nokia, but I swear it makes me jump out of my skin sometimes. Why can't you Nokia guys fix those things before you put it out to market??
Don't blame Nokia. Their unique fault was partnership with Microsoft.
P.S.: totally satisfied with phone. It took almost 5 days to discharge since last upgrade + no problems with software update/installations.
I purchased my Nokia Lumia 800 about 10 days ago while I was in Paris.
I love the unit and the battery life an all.
However, overnight it decided to land in a vegetative state.
No response, no power one, not combination of keys is inducing a reset.
Very odd coming from Nokia, I had decided to kill my HTC HD7 Pro because of the instability of the device.
I have also tried this and it is not working. When I plug it into my PC, the PC asks me if I want to format the drive. I choose "cancel". I let the device sit for a long time. I then press and hold power for >10 seconds and get nothing. When I release the power button, the phone vibrates and then ~1 second later gives another very short pulse vibration.
What should I do?
Hi. My 800 is stuck in an infinite restarting loop. Tries to start up, fails, and tries to start up again over & over but never boots up.
Tried already USB connection to PC or laptop
Tried another power supply from different NOKIA phone (N97 mini, 1200mhA)
Tried to warm ti up and then connect it.
Tried doing soft reset.
Tried doing hard reset.
Any other suggestions?
I have the same situation here. My phone is dead for 4 days already, and I am really loosing my patience. I am going to plug out it's battery and charge it directly, if I will not receive official support soon. There are hundreds of people complaining about this on the Internet, and I think there are several others out there that prefer to remain silent.
Nokia, do something, asap, or soon you will have nothing left to do.
