DO NOT COLDFLASH when your device does not need it!
Coldflashing is solely to restore a broken bootloader, and obviously your bootloader isn't broken since it boot up to display stuff on screen and even starts flashing procedure. If it was broken then your device would act _really_ bricked and not show any sign of life (except BOOTROM "hello" via USB, that gets detected by flasher). ONLY THEN you should consider coldflashing - after you made sure it's not your battery that's defect.

It's not like coldflashing could do massive harm to your device since you can repeat it under nearly all circumstances (unlike flashing BIOS of your PC, which might render your motherboard bricked when you abort it), but definitely it won't usually fix anything for you, and just may introduce another level of failure cause that complicates things even further.

on the errors you encounter: try a better USB cable and a different port on your PC, those errors *might* be simple data corruption on USB protocol.

ok I have changed the USB Cable - I have tried 2 different computers. But I have the same problem. Any other ideas?

Do I have any choice guys? Please respond.

Should I take this to Nokia Care? I would be charged for this but I am ok with it, as long as they fix it.

Are you from India?
DO NOT take N9 to Nokia care, many nokia care guys hardly have any idea about N9. They will tell very high service charge and will not be confident of fixing it.

Could someone possibly help me?

I'm unable to flash to UK or Aus or Denmark FW 001, 299 or 340 variants.

Here is my log attached:

Phone is just bootlooping now... Any assistance is greatly welcomed!

Nevermind! Was being stupid / dyslexic and had downloaded 249 variant. Managed to flash fine with 299

Whenever I plus in my n9 it always comes on, how can I reflash like this? It comes on and stays at the Nokia screen.

This is weird!

I did a secure erase on my second N9 just now and during tbe first setup process (where you set time, date, language....) the device remembered my nokia account user name!!!!

whats secure about that??

press the power button for 8-10seconds before plugging into usb port for the n9 to be powered off...

Yes I got it, I'm trying to see if its the death by batter drain issue before flashing, I hope it is lol

edit: nevermind **** is bricked.
