Well DLOAD and Qualcomm aren't separate 'modes'. They are separate bootloaders. The DLOAD overwrites the Qualcomm one ... permanently. So the Qualcomm one no longer exists on your phone. And there's no (signed) firmware that can overwrite it back.

so the only method is to flash the original bootloader right?

unfortunately this isn't possible at the moment

Why i have used NCS

well there is something strange. Actually, i updated my phone once through zune to 11451 and i am still on it and i get Nokia dload. by the way i get the phone from London in December 2011.

I'm back on my backup. Sideloading apps worked, but Root Tools said my phone would be incompatible (which I can understand) and XapHandler threw an exception (it handled the error correctly and showed an error message, haven't noted it down though). Also, the already mentioned problem with my Live ID bugged me a little. I'll wait and see for further improvements. Can't wait for the release of the new OsBuilder.

if I downgrade my LUMIA 800 to an older firmware, will this maybe unlock the bootloader?

Please, READ before posting :

1) It has been said and said again, No, you CAN'T get the Qualcomm bootloader if you have Nokia DLOAD, for now.

2) There is another Topic in the general category to ask question, this one is for developers.

Thanks.

I did it on other L800 with HW 2.1 but Lumia is restarting itself every 25s?????

No, there is currently no way to flash the bootloader used in order to gain Qualcomm mode.

this could be normal because we actually just copy the custom rom on nand and I think some parts of nand (the part where the phone id key is stored) is not formated/working right

so I think when you use custom roms like this this always happens

Are you sure about that? I guess that this code is stored on a diffrent partition… If ist stored on the NAND it would mean that flashing a ROM using NCS or some other "official" Tools does something else than copying it to the NAND like we do...

Maybe a silly question but where else would you store it?

X3n0n · Apr 14, 2012

Maybe in one of the eight other partitions ?

Given that for now, we just apply the file to the ninth partition.

I think the problem with Windows Live is in fact the Interop Unlock. It happens on both Lumia 710 and 800. I think the issue is with these keys:
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg]
"PortalUrlProd"=dword:0
"PortalUrlInit"=dword:0
If it can't register the device with microsoft, two things happen:
1. They can't remove your interop unlock
2. They can't get your device registered, so you can't link your WL ID to it without calling them.

I can't confirm it since I don't have access to any other Windows Phone. Can anyone check if I'm wrong?

Oops, I thought NAND was actually all partitions together and not one specific partition

pdukanac · Apr 14, 2012

This was issue with htc hd2, thats what i remember

imo ChrisKringel is right, since first hd2 roms were not interop/full unlocked, i even had to do chewron unlock myself and yet that activation key was needed.

real problem is that key is unique per device and that brings me back to ChrisKringel assumptions

UPDATE:

Now time to play with bootloaders and try to get this to work for everyone!

Hi,

Ok, after talking about the weater and my underwear, i can post here.

First, great work and great find !

I read the whole thread and it seems the first loader at 0x04500000 is not
checked runtime for a correct signature. This can only explain being stored in
the second partition without matching certificate.

I know it is risky, but can you maybe modify a string inside, to see if the phone
will boot ? There is a recovery procedure in the Nokia bootloader, to restore
via command from some backup location if there is a problem, not sure if the
Qcom loader has this.

Also can you dump the actual bootrom of the chip (the one that calls the osbl
loader) ? Via custom app, or modding a dll, etc ?

Ok, the reason people are having issue with the Product Activation Key is because normally when you FLASH a firmware the key is pulled on the first boot from where it is stored on another part of the phone. When you simply copy over the NAND with new data and don't do a normal flash this first boot process never happens and as such your phones key is never entered into registry. This is also why people are having other issues, the first boot process does some important stuff. We need to figure out how to trigger this process manually.

The interop registry keys have nothing to do with the Product Activation Key the registry value for that is as follows:

Code:

REGEDIT4
[HKEY_LOCAL_MACHINE\Software\Microsoft\GwpCPC]
  "ActivationCode"="*****-*****-*****-*****-*****"

On another note I got my hands on two new direct from Nokia Lumia 800's (unlocked/unbranded) both HW version 2.3 both with firmware 11451 and both with Nokia DLOAD. Some things I noticed that are different about these two from my original Qualcomm bootloader Lumia is that on the lable on the outside of the box where the IMEI number and such info is my original Qualcomm says "Nokia World 2011" in the upper right part of the lable where as the other two don't, also the UPC is different 6 438158 405332 for the unlocked one and 6 438158 373808 for the two locked ones. Another thing is they have different 'MATERIAL' numbers as well the unlocked one is 002Z570 where as the locked ones are both 002X5P9. Digging deeper the IMEI for the unlocked one is of series 359289040XXXXXX and the locked ones are of series 359289047XXXXXX. Physically on the unlocked phone the 'Windows' button has a slightly larger gap between the four parts of the flag than the other two, we are talking very small difference here but enough that I can notice it.

So for anyone looking at a store or something keep these things in mind when you try to buy one. Also this is all for the Euro 801's not the US versions. Also if anyone is interested I would like to trade one of my DLOAD Lumia's for a Rogers Lumia 900, I'll make a thread in the marketplace for that though.

how to unlock bootloader ?

You can't. It either is or it isn't. Realy if you would have read just a little bit before you posted you would have found that out.

brummiesteven · Apr 14, 2012

I *think* I have a unique problem, have scanned through these pages and not found anyone else post anything similar...

I have a launch Black Lumia 800 (November 2011) so I assume it has the unlocked bootloader however there doesn't seem to be a way to check.

I've tried the following

Hold VOLUP + VOLDOWN and connect the USB cable at the same time, screen goes black and Windows indicates a device plugged in with the standard sound... Nothing shows up in Device Manager however. After about 10s the device disconnects and the Lumia proceeds to boot as normal.

VOLUP + POWER Device boots as normal

VOLUP + VOLDOWN + POWER Device boots as normal.

Any ideas?
