Is your bootloader unlocked?

Recommended Posts

If you have recently acquired a Nokia Lumia device, you may be surprised to find out that Nokia has not locked down the bootloader, giving full NAND read/write access!

To check:

  • Turn off your phone
  • Hold down Volume Up and Power
  • Connect your phone to your computer with the USB cable, you will hear a short vibration
  • Keep holding those buttons

Check your computer and see what device is detected. You can find this in Devices and Printers on Windows, in the Device Manager, or just check what device it is trying to install drivers for. If you're on Linux, run lsusb.

On Windows:

if you see NOKIA DLOAD, you have a locked bootloader.

but if you see Qualcomm MMC Storage USB Device you have an unlocked bootloader!

On Linux, using lsusb:

if you get Qualcomm, Inc your bootloader is unlocked.

I have a slightly different message, "Qualcomm CDMA Technologies MSM" on my Lumia 800

And while doing this managed to start the lets pretend to be a bricked device again syndrome. Now to wait until it will let me reboot again.

Not that I noticed, this was tested on W8 so may be slightly different to a W7?

I think it is something different for the lumia 800. I tried loads of times without sucess. Then I held both volume buttons and got it on the second try. By definition though if you can update with Zune you have Nokia Dload

I used to be able to get into osbl mode (vol-up + power) but for some reason not anymore.. althou by using a program called NSS Pro , I can get there. The good thing is that my lumia shows as Qualcomm CDMA Technologies MSM , as it should , but it does not map any drives... exactly the same on linux side : It's idenftified (lsusb) as Qualcomm Inc. but still no drives :/
