[amarok2]

hi,

i have tryd to install a custom rom.
now i want to install the original rom.

i have flashed the original rom backup to my lumia 800 and now its dead.

how can i flash the original firmware?

if i hold the volume-up + power button i can see the qualcomm device.
if i start my lumia normal (hold only the power button) it vibrates for a few seconds but the screen is allways black.

with the Nokia care suit i cant flash the rom.
every time i try to flash the firmware, nokia care suit shows me the same window (screenshot is in the attachment)

Hi,

No gurantees, but try a hard reset;

With the 800 off press VOLUME DOWN-POWER-CAMERA all together
Wait for vibrate
Release POWER
Wait 10 seconds
Release all buttons
Lumia should vibrate
Power on

Hope it helps you get the phone backup..

If Hard Reset Method doesn't help you:

Actually, your Nokia Lumia has it's BOOTLOADER damaged.
The only thing that will work is RIFF JTAG.
You can solve this by going to Nokia Care / GSM Service.
