Default [GUIDE] How to flash a dead Lumia 800 RM-801

Tried today to debrand my Vodafone italy Lumia 800... the flashing with Nokia Care Suite stops at 50% and the phone stuck in flash mode.

The last Nokia Care Suite (2011.51.2.63048) can't flash RM-801 in dead mode so i shat my pants.

Reading the care suite docs carefully i've found this:

Code:
Recovery Flashing enabled for RM-817
So after few tries i've found the right way:

Create a RM-817 dir under \Products folder, like this:



then copy RM-801 firmware files in RM-817 folder:



Now open the Care Suite and select the right model (RM-817):



Select Recovery:



Select the correct flash file, remember to use always the latest version, check on "Data package manager" for updated firmwares.



follow the instructions on screen:



When you are ready connect the phone holding the volume up button and let the care suite do his job:



After few minutes:

Good find!

Can you read your product code after this recovery procedure? Maybe with this procedure it actually gets changed to the debranded product code. Thanks for checking.

Yes, it changes because if I select "Refurbish" the nokia care suite automatically selects the unbranded firmware.

Are you sure? So it selects the unbranded firmware [which you didn't rename to fit your branded product code]?

If so then you have just found a way to truly debrand the Lumia 800 because with the refurbish option it won't change the product code. That's why for refurbish flashing you needed to rename the files.

With the product code changed your device is just like an original debranded phone, so it should be updateable using Zune without a problem (this may have been a problem with the previous method).

Nice!

As you can see, the firmware in the RM-8XX folder have product code 059L820 (RM-801_CV_IT_SWU204940_Black_v2)

The phone originally was 059L705 (RM-801 Vodafone IT IT VAR204289 black V3)

Great discovery but no Nobel vote from me. Product code is the same than was originally.
