@biktor_gj: When you get some time, since you have experience with building Lumia ROM's with OSBuilder, could you try to cook a stock ROM and see if that gives you better results (like not stalling at 'installing apps') than a 'dirty' dump. If you can get that working you will have put the Lumia 800 in the same elite group as first gen HTC's and Samsung's, able to have custom ROM's! Interop Unlock is small potatoes compared to Full Unlocked custom ROM's!
[Nokia Lumia 800] ombadboy:
Great news biktor! Will do wonders with my unlocked? bootloader (qualcomm detected by windows)..

Let's hopefully find a way to use that bootloader on Nokia DLOAD Lumia handsets!
[Nokia Lumia 800] beidl:
Awesome work! :D

Tell me your secrets please! I'd like to get it going on the 710.
[Nokia Lumia 800] ShotSkydiver:
So, if we have a HW Revision 112.1402.2.4, this isn't going to work?
[Nokia Lumia 800] suzughia:
Let's the research continue! Seems early to speak, let's see what's other!
[Nokia Lumia 800] sHaHiN786:
ACE!! :D
[Nokia Lumia 800] biktor_gj:
Hey, first yes, I changed PortalUrlProd, PortalUrlInt, and LVMod. Strange enoguh, MaxUnsignedApps was already set to the correct value.

Don't get me wrong, Interop Unlock is good and all, but I just wanted to get this working to delete it from my task list and because I promised ultrashot I would try it. It worked like a charm, so now we'll get back to business.

I haven't given up on Nokia's Dload OSBL yet. I have two Lumia 800, one unlocked, and one locked, and my next try will be at crashing the locked bootloader and attempt to restore qualcomm's. Hopefully the fact that now we have interopunlock just makes it easier to test some other things inside windows phone, like access to the flash. If NCS really flashes the new bootloader before rebooting the phone like some people said somewhere on this thread, we should also be able to do the same some way, and maybe with InteropUnlock we can test some more stuff. This is just the beggining of the way ;)

Of course all this doesn't mean anything. Maybe it's impossible, but if there's a possibility of getting qualcomm's loader back I have the need of trying until I break both phones or until it works ;) At least we have a clean copy of the loader.

About those .vol files, on the OS dump I can only find mxip_notify. Is it something the OS does at first boot or something? can you tell me how to retrieve it so I can send it to you?

@beidl and @everyone asking for lumia 710 stuff: I have a private beta of OSBuilder, it's what let me recompile the rom without errors. Tomorrow morning I'll post a test firmware with interop unlocked for the 710, but I can't guarantee it'll work because I don't have anything to test it on, so you'll have to be the betatesters ;)

I can't provide the OSBuilder beta, because I don't have permission from the developers. If they're fine with it I don't have a problem either, but I'd be better off letting them release the final build when they think they're ready to do it
[Nokia Lumia 800] X3n0n:
Congratulations, you did a reaaaalllyyy good job !

You just opened the way to custom ROMs on Lumias, well, for those with open bootloader, but, I hope you will be able to do it on every lumias available !
[Nokia Lumia 800] Heathcliff74:
It's hard to say on which partition you should look. I don't have an unlocked bootloader to play with, so I'm in the dark regarding that.

Those .vol files are in rom on \Windows\ and at first boot they are copied to \Windows\Security. After that they are used from there. Every update and app install will modify the databases. So to have a clean copy, we need the one on rom from \Windows\. If that can be patched, you should restore it and hard-reset to use it. You should be able to find the files by dumping the rom partitions.

Ciao,

[Nokia Lumia 800] djtonka:
i just installed fresh ubuntu and cant force L800 to boot as mass memory. I did it with L710 any ideas?

Lumia 800 got 12070 at the momemt by NCS
[Nokia Lumia 800] ChrisKringel:
May I ask if you flashed a whole 15GB file back to your lumia, or only the ROM? As soon as the OSBuilder Version is released I'll try it with my RM-801 as well...
[Nokia Lumia 800] Giblet-dono:
So I would love to know how to flash it..

I download the files and got the unlock mode..

But which program do I use to flash it?

Thanks in advance, and congratulations!
[Nokia Lumia 800] SuperUserMovado:
maybe this is too early to ask but any hope of booting a linux kernel on this? as stated before it is using same chip as xperia arcs,galaxy s plus etc
[Nokia Lumia 800] beidl:
I already have started working on an Android compatible bootloader, and the bootloader itself boots, but I'm having trouble getting the display to start. Still, I can see the bootloader boots because it kicks into fastboot mode automatically.
[Nokia Lumia 800] heishanxiaoyao:
It's cool!Thanks Man!
[Nokia Lumia 800] sensboston:
GOOD JOB!

Great job, congrats!!! :D You 'da man! Please add your paypal address to "Donate to me" button, I'll send you a sixpack :)

P.S. I hope someone can make same stuff for Lumia 900!
[Nokia Lumia 800] uccfar:
Congrats biktor_gj !!!

and thanks for sharing the new os

is there a way to use these files with Nokia Care Suite and refurbish the Lumia 800..

Sorry noob here :P
[Nokia Lumia 800] xsacha:
The ROM isn't flashable. You need to have an unlocked bootloader and then connect to your Lumia while it is in 'Disk Mode' (detailed in first post) and then move the firmware on to the device.

For the people saying they will be buying a Lumia 800 now. Be careful! The ones you will find in the shop are already using the newer firmwares, flashed with the new bootloader and won't be able to do this!

Your best chance, at this stage, is probably buying a used one off eBay.
[Nokia Lumia 800] ultrashot:
Most likely we will release new OSBuilder next week and post it in its thread :)
[Nokia Lumia 800] djtonka:
Do it for L710 :)
[Nokia Lumia 800] heishanxiaoyao:
Where download the unlock BL?
[Nokia Lumia 800] lilstevie:
you either have it or you don't, at this point in time there is no way to downgrade OSBL to the vulnerable version
[Nokia Lumia 800] heishanxiaoyao:
It's a bad news!:o

Thank you for your answer!:)
[Nokia Lumia 800] imotz:
witch version is the unlocked bootloader, how can i find out if my device has an unlocket bootloader?
[Nokia Lumia 800] suzughia:
Shut down your lumia, press vol + and vol - together, plug into usb and see what's on device manager: if Nokia DNLOAD your bootloader is locked, if ask for format say no and you have unlocked one.
[Nokia Lumia 800] djtonka:
My L800 seems like unlocked follow your instruction but is not reconized by linux.

Other things is L710 is detected by linux as mass memory...

L800 ending is 2.3

L710 ending is 2.1
[Nokia Lumia 800] suzughia:
What's the output from dmesg or see what lsusb says.
[Nokia Lumia 800] ShotSkydiver:
Read through the entire thread and I never saw this happen to anyone else... when I do the VOL UP + VOL DOWN boot, it does the short vibration with the black screen, and for a little while "Nokia Connectivity" shows in the device manager. No mention of DLOAD anywhere.

Running a 2.3 HW rev on 11414.
[Nokia Lumia 800] suzughia:
On mine Lumia 800 with 2.4 hw rev I can just press vol+ plus vol- then connect to usb, after a short time a short vibration is sensed and if you keep pressed Nokia DNLOAD should appear, but I keep the buttons pressed.
[Nokia Lumia 800] suzughia:
I forgot to mention that you start with your device powered off.
[Nokia Lumia 800] Fisher_9511:
Such beautiful words :p. Thanks for this exploit, I hope that it will be available for all Lumias some day.
[Nokia Lumia 800] biktor_gj:
Updated first thread, and added Lumia 710 test rom. Can't know if it works, so anyone wanting to play a rom, check it out!
[Nokia Lumia 800] ChrisKringel:
So both, the Lumia 800 and 710 ROMs are based on ROMs obtained through NaviFirm? Have you tried to edit your 15GB DD ob the sdX9 partition?
[Nokia Lumia 800] heishanxiaoyao:
I'm not a luck user!:o

but,a big thanks for you!:)
[Nokia Lumia 800] Heathcliff74:
Unfortunately for you that is NOKIA DLOAD. On some machines it is recognized with a different name. But tgat is the HardwareID of the NOKIA DLOAD.

Heathcliff74
[Nokia Lumia 800] biktor_gj:
Yes I tried, and failed miserably ;),I got to extract the full packages, and rebuilt it but it wouldn't pass the Nokia logo. I think if you clean the 15Gb dd dump you might actually get a working build, but it's harder to manage, and OSBuilder gives problems with that file size. I also don't have a 710 to get a copy of that partition, and I really only want to get this to work and focus back on the bootloader stuff.

This is only to get going until next version of OSBuilder is out and everyone can do it :)
[Nokia Lumia 800] beidl:
Are there any best practices? Like filling partition 9 with zeros beforehand?

Might be something I'd like to try in case there are any problems. I do have a full backup anyway.
[Nokia Lumia 800] biktor_gj:
I wrote that about recompiling the dumped DD image using OSBuilder. If you just want to have a backup it's more than enough with the DD image. If it doesn't boot, DD it back to the phone and it will boot normally (I don't know how many times I've done it already). The problem is creating a derivative rom based on the 15gb dump. Too much data. That's why I said, if you crop the file at about 400Mb, you might actually be able to create a custom rom based on your running ROM.

Sorry, english is not my native language :)
[Nokia Lumia 800] beidl:
I'm paranoid, I have a backup of every single partition on several locations (even including the whole sdb device itself) :)

Just backing up again, I'll report after flashing the ROM.

EDIT: Your english is great, and it's not my mother tongue either ;)

EDIT2: Also, you better should add a donation button to your profile... ^^
[Nokia Lumia 800] djtonka:
my is dead after succsesfull copying:)
[Nokia Lumia 800] boneszbo:
djtonka have Nokia Lumia 710 not 800 ;)
[Nokia Lumia 800] djtonka:
not in this case:) anyway i have to replace engineboard second time...
[Nokia Lumia 800] biktor_gj:
Some more info please... does it long vibrate when powering up? Shows nokia logo? Goes back to disk mode? Did you reboot the phone after writing the file..?
[Nokia Lumia 800] djtonka:
no anwser at all. L710 does not have Reset by keeping pressing POWER so i replace battery after I could not make HR as well.
[Nokia Lumia 800] beidl:
So... it finished booting, but when I wanted to log in, I got this:

Don't know if I should try calling them.
[Nokia Lumia 800] biktor_gj:
Maybe my source firmware had some kind of problem... I'll try to find another, more or less updated firmware and recreate the rom just in case... But to be fair, I didn't even try to login to msn after unlocking ;)

Will take a look and post an updated image when I'm ready.

For the rest, does it let you sideload apps?
[Nokia Lumia 800] dirtywood:
Please its id posdible to instalo with Windows 7 OS?
[Nokia Lumia 800] ceesheim:
I build a full unlocked tango rom but I can not test it , I will upload it so that all can test.

oh don't blame me if it didn't work because I don't have a nokia to test it

and yes I also have a osb that can build winstore roms :D
[Nokia Lumia 800] suzughia:
I've got a 2.4 hw rev Nokia, I've searched into Navfirm and found that into 11414 & 11451 there is no osbl update, the first osbl update for Cyan Lumia come in 11501 and we also have an osbl update in 12070.

The first time I've connected my Lumia to NCS it reported 1600.2483.8106.11500 - stock rom bundled with the phone - then I've updated it to 1600.2483.8107.11501 and 1600.2487.8107.12070 but with Zune.

Can anyone confimr that the osbl update into 8107.11501 is the one who lock the bootloader - or is the unlocked one - or is 8107.12070 that locked it? If not i don't know how to recover the 1600.2483.8106.11500 ROM, probabilly I've got a backup made on my Mac with Windows Phone 7 Tools - I can't remember if the name is correct -.

Any hints or speculations?
[Nokia Lumia 800] lilstevie:
there are no firmwares containing the Qualcomm eMMC passthrough OSBL on FiRe unfortunately, if there was we would have an easy downgrade method for all Lumia 800s
[Nokia Lumia 800] scalaneo:
Hey mate. This happened to me before. Just go the zune online help and chat with them.

Ask for the 20 digits windows live activation code. Share them the info (what phone, operator and imei). They will supply you the code in a matter of minutes.

:-)
[Nokia Lumia 800] ChrisKringel:
I wonder why this occurs in the first place… I'll try to do some Research as soon as the OSBuilder beta goes public… BTW did you check if These ROMs are capable of updates?
[Nokia Lumia 800] ceesheim:
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
[Nokia Lumia 800] frenk_91:
Any progress with Nokia DLOAD ???
[Nokia Lumia 800] Giblet-dono:
After a sucesfull copy my Lumia 800 is dead..

just as djtonka's 710

It doesnt do anything, I tried every button combination, it doesnt vibrate,,

It doesnt show anything and when connected it doesnt trigger antyhign on the pc.

So I think it's bricked...

I would love some feedback, and if I can try anything else, please just tell me!

what I tried:

Holding power for 10+ Seconds

Holding VOLUP + VOLDOWN + POWER for 10+ Seconds

Holding VOLDOWN + CAMERA + Power for 10+ Seconds

Holding VOLUP + VOLDOWN + POWER for 10+ Seconds + Connectiong USB

Thats All for now, Thanks in advance for any help
[Nokia Lumia 800] shakeyabooti:
I second that...
[Nokia Lumia 800] lilstevie:
This to be honest is unlikely, Nokia DLOAD talks with NCS, which requires signed certificates with each file that is sent to the device.

I had this about an hour ago, you will either need to wait for the battery to go flat, or open the device and disconnect the battery
[Nokia Lumia 800] biktor_gj:
Try first ten seconds power, then release, the hold volume up and power. If you flashed the file in partition 9 your bootloader is fine. Either it just got stucked or run out of battery (happened to me). If the last is the case, hold volume up, plug usb and then hold power...
[Nokia Lumia 800] EmaTheLegend:
Lumia 800 DLOAD... waiting for a solution :)
[Nokia Lumia 800] xsacha:
Ok, because your phone came with firmware 11500, it also came with the nokia OSBL. Which means it was already locked.

Zune updates do not affect bootloader.

Also, 11501 = 11500 (Zune updates have a +1).

There is no firmware that flashes an unlocked bootloader. If you had a phone pre-11500, it would have had an unlocked bootloader loaded in the factory.

You cannot 'restore' pre-11500 firmware because they do not include the qualcomm_osbl which is required. Also, of course the bootloader is not included in any backups.
[Nokia Lumia 800] suzughia:
So it's pointless trying to restore to my default firmware with hope of showing Qualcomm bootloader, thanks for your time and for keep me away from wasting mine.
[Nokia Lumia 800] sHaHiN786:
Hmmmmm......my Lumia 800 is one of the first batches as I bought it on release and it came with the first firmware version, but I did send it to Nokia for repair, and they flashed 11501, since the updates don't overwrite the bootloader, is it safe to say that my phone is unlocked?

When I try the bootloader trick (power+volume) and plug in to USB mode, I get the short vibration and all it shows on Windows Management is 2 Healthy OEM partition, nothing about Qualcomm, running Windows 8 CP.

I is a lttle Noobie. Thanks. :D
[Nokia Lumia 800] frenk_91:
there isn't way to force the phone from DLOAD mode to Qualcomm mode like this?

or is possible to repack the fw and use NCS to flash it?
[Nokia Lumia 800] suzughia:
I've opened a thread into the general forum for NON TECHNICAL questions and non usefull comments, please leave this thread to the developing and to the developers, you can find the Q&A general thread here
[Nokia Lumia 800] xsacha:
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.
[Nokia Lumia 800] frenk_91:
use this Beta of NSS.

Need to change mode after your phone is detected:

one special thanks to Bph&co how discover tis software
[Nokia Lumia 800] SuperUserMovado:
same as :

Bus 001 Device 041: ID 0421:05ee Nokia Mobile Phones

on linux
[Nokia Lumia 800] frenk_91:
so the only method is to flash the original bootloader right?

unfortunately this isn't possible at the moment :(

Why i have used NCS :mad:
[Nokia Lumia 800] saud__19:
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.
[Nokia Lumia 800] beidl:
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. :)
[Nokia Lumia 800] Turkishflavor:
if I downgrade my LUMIA 800 to an older firmware, will this maybe unlock the bootloader? :confused:
[Nokia Lumia 800] n73gamer:
congrats

wow guys im following this thread since the first post and wanna congratulate you for your success on bringing the first lumias to its interop unlock! CONGRATULATIONS!

I also testet how my Phone reacts and i get the Nokia DLOAD but with the revisionnumberending of 2.3

My actual fw is the 12070 one...

i hope i get the interop unlcok soon :P

if i have it ill donate the one who got it 7 swiss franks, which makes 8 US-Dollars..

no joking ;)

and the rest of the active guys get 2 franks (2.1 dollars)

bcause i really wanna support you (i mean you all should be supported)
[Nokia Lumia 800] X3n0n:
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.
[Nokia Lumia 800] djtonka:
I did it on other L800 with HW 2.1 but Lumia is restarting itself every 25s?????
[Nokia Lumia 800] ChrisKringel:
No, there is currently no way to flash the bootloader used in order to gain Qualcomm mode.

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...
[Nokia Lumia 800] _Madmatt:
Maybe a silly question but where else would you store it? ;)
[Nokia Lumia 800] X3n0n:
Maybe in one of the eight other partitions ? :D

Given that for now, we just apply the file to the ninth partition.
[Nokia Lumia 800] biktor_gj:
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?
[Nokia Lumia 800] _Madmatt:
Oops, I thought NAND was actually all partitions together and not one specific partition ;)
[Nokia Lumia 800] pdukanac:
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
[Nokia Lumia 800] Bph&co:
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 ?

BR
[Nokia Lumia 800] voluptuary:
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:

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.
[Nokia Lumia 800] Tan-Killer:
how to unlock bootloader ?
[Nokia Lumia 800] voluptuary:
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.
[Nokia Lumia 800] brummiesteven:
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?
[Nokia Lumia 800] Bph&co:
Hi,

Device Manager is bad way to check. Get UsbView and use in Auto Refresh mode.

BR
