I had installed power-kernel because I wanted use Qt Mobile Hotspot. Now later my phone started to act up, camera didn't work and the phone kept loosing connection to my sim card, so I presume something went wrong when I installed P-K. I now know this was not the case.
I uninstalled P-K according to the instructions(using x-terminal and installing nokia kernel) and that lead to boot loop. I've been trying to reflash my phone, but for some reason when I attach my phone to the USB mini cable I get error when the device starts installing drivers, so the flasher never does detect the connection and thus never even starts the process. I have enabled so called "test mode" in my windows where unsigned drivers should work(says so on my screens lower right corner), since there seems to be some issues with 64bit windows, atleast thats what I read.
I'm lost here can anybody give me any instructions?
First let me say I already knew about the U key+usb cable thing.
So tried what you suggest Mitrigol and same thing happened as some many times. The phone is off, I start pressing U key, I attach USB cable and a dim nokia logo with USB icon in the right upper corner appears, and nothing, flasher just sits there "suitable device not found, waiting". It doesn't matter if I execute the flasher before or after inserting the USB cable. Also I get this when the phone tries to install drivers "Nokia Usb ROM - Not Found".
Where you already able to flash your phone from the same computer before (As i understand you have win x64?)?
If not, connect your phone on the computer, open Device Manager and check for the not properly installed hardware (which obviously should be the nokia) right click and select uninstall. Be carfeul to check the "also delete all drivers" option available at removal.
