How to upgrade to Nokia DLOAD - Nokia Lumia 800

1. Download the file
2. Change the extension of the downloaded file. Zip (should happen: RM803_12w07_prod_generic_updated_nokia_osbl.zip)
3. Open the file. It should contain two files. We take out the file «nokia_osbl.mbn».

4. Connecting the Nokia 710 to a computer in a mode of Qualcomm (Turn off the phone. Hold down the volume + and connect the USB). We wait until the removable drive will appear.
5. Download the program "HxD" ftp://wa651f4:[email protected]/HxDSetupEN.zip
6. Run as Administrator HxD. Click the "Advanced -> Open Disk." My phone number appears in the program as a "Removable Disk 1."
7. We find our phone number. Remove the check mark "read only". Click "OK". The section begins with a boot sector with number 1001. To quickly find the sector take advantage of the panels at the top.
8. Make sure it starts with a «0B 00".
9. We hide HxD open it phone.
10. Now open the file «nokia_osbl.mdn» HxD in and copy all its contents (you can press Ctrl + A and Ctrl + C).
11. Go back to HxD open the phone.
12. At the beginning of the sector in 1001, about the letters «0B 00" right click and click 'Insert the replacement. "
13. Save the changes.
14. Disable USB. We take out the battery. Turn on the phone. Now you can flash with the NCS. But in order to install custom firmware, you have to re-open mode of Qualcomm.

As far as I know you can update a Lumia 800 to DLOAD via the NCS. I'm not really sure why you would do this, though.

I am new in this field, but i you know a solution to DLOAD my lumia 800 with NCS, please share with me, cause i totally ignore how to do it. Thanks in advance

So, once upgraded to Qualcomm, if ever it needs to go back to Nokia DLOAD, just use these steps, am i right?

Can you elaborate on how to do that?
The Power+VolUp and recover? OR some other trick?

Yes, please do elaborate. I'd like to convert the Qualcomm bootloader on my 800 to the DLOAD.

I have the QC bootloader on my phone and I'm having a heck of a time trying to upgrade it to the Tango update. I feel like it's the QC bootloader that's somehow blocking me from using NCS. I have a thread for my problem http://forum.xda-developers.com/showthread.php?t=1734174.
I think if I can get the DLOAD on my phone then it can get stock upgrades...but at this point, my phone is stuck with an old version with no upgrade path.

NCS doesn't recognize my phone
I upgraded to DLOAD from Qualcomm based on your instructions. That went well. But even now, Nokia Care Suite doesn't recognize my phone. I want to flash latest roms and don't need modded roms. Please let me know as to how I can do this. TIA
Edit: NM, I was able to do it.

answered my own question
i missed the bit where it said read only and untick

---

How do i insert replacement? I dont see the option under right click.
I am running HdX as admin and unchecked read only. I can see the option when in the downloaded file but on the phone side it is grayed out.

---

Can you explain better...
12. At the beginning of the sector in 1001, about the letters «0B 00" right click and click 'Insert the replacement. "
no image of this should i overwrite "0B 00" with all file's content, insert before "0B 00" or overwrite all the content of the sector 1001?
Thanks for the help
PS: no "insert the replacement" option. only paste/write

Sorry but... what is the difference between DLOAD and Qualcomm? Is one of those "better"? thanks.
