Hi all.
I have a Nokia Lumia 800 which one evening I was powering off. The next moment I tried to turn it on, it appeard to be stuck in a boot loop or something. It vibrates for two seconds, then after a few seconds, a short vibration comes. This will go on in some kind of loop.
Don't know if the bootloader is trying to get the main FW up and running, without succeeding.
The local smartphone repair centre was trying a new battery and a new screen without getting it on. They simply wrote in their report "mainboard dead".
They did not have the possibility of flashing the FW.
Obviously the phone has some corrupt firmware and it needs to be reflashed.

Here is what I've tried:

I downloaded the Nokia care suite but it seems it does not support flashing a dead Lumia.
I also tried Nokia Software recovery tool, but it cannot connect to the phone - sometimes reporting "cannot read device" and sometimes "the phone is not supported"
I'm running Windows 7 and my PC. Does it perhaps require WinXP?

What can I do?

Thanks in advance, really appreciate it!

EDIT: I tried to follow the guide in this forum how to flash it with Nokia Care Suite, using RM-817 instead of RM-801.
But it seems I don't have the productfolders in this guide containing RM-801. Please help!!

Okay, check this out:

First alternative, try a soft reset:
1. Turn off your Lumia, and press Volume Down + Power button until the phones vibrates and restart

Second alternative (you will lose all your content on the Lumia), try a hard reset:
1. Press and hold the Volume Down, Power and Camera key simultaneously until you feel your phone vibrates, then release the Power key and continue to hold the Volume Down and Camera key for a further 5 seconds.

Now your phone should start to return to the factory default settings

Last alternative (you will lose all your content on the Lumia), Chimeratool:
1. Try to install Chimeratool (https://chimeratool.com/downloads) on your computer, and make a trail account
2. Turn off your Lumia, then connect via USB, while pressing Volume Up
3. Try to click on "Factory reset modem"

Good luck!

Would you believe it, the chimeratool fixed my Lumia 800 !!!
THANK YOU SO MUCH Youngboy.
I didn't thought it was possible to save the Lumia without a J-TAG gadget or something.
Doing this by pure USB connection is pure magic.
And the phone kept all my personal stuff, pictures, contacts and so on. Great!

Again, thank you very much!!

My phone has the exact same symptoms, but even after doing anything you suggested it still does not turn on.
Is there anything else I could try or should I consider it gone for good?

I have exactly the same problem on my Lumia 800 (RM-801), that my Lumia won´t start when my battery is completely discarge by putting it in the charging cable. My solution is to first put the charging cable in the Lumia, and lett it charge for around 45 minutes. Then take the chargingcable out. Hold the power for around 15 second. Then release it. And hold it again.

in my case when the battery is completely discharge i put the phone in charge (when i plug the cable charges phone vibrates for 2 sec and 1 sec), no display battery red icon appear on it so i leave it charge usually for 5/10 Min then after i disconnect charger, press start for 2 sec and the phone boot... note: with official firmware WP 7.8 the boot sequence is ok but i think that little problem is a good compromise for have installed rainbowmod on my lumia ;D
