[Nokia Lumia 800] deylo:
well well well...im experiencing this same problem. i opened the second partition (starting at sector 1001) and replaced everything there onwards with the contents of a new osbl and wasnt able to flash with NCS nor NSS. if you get a resolution let me know. i am trying to work on one now. what i am trying to do is extract the osbl and replace the .mbn file in there with another. i did that and now when i tried to flash with NSS it didnt fail. however the other file to be flashed failed. there is where i am stuck at the moment
[Nokia Lumia 800] ultrashot:
Biktor, btw, my friend with Lumia 710 built a rom with full unlock and it worked. Probably you've just missed an OSBuilder's option about XIP on "Building - 2" tab.
[Nokia Lumia 800] Bph&co:
Hi,

The phone works fine, just not able to flash any file or replace the badly edited

loader.

Yes, i got the idea to include backup copy in the next partition, but too late now.

BR
[Nokia Lumia 800] biktor_gj:
I'm pretty sure you're right :) I have yet to try your last advice and see if that at least works... but there's so much to do and have so little time (sbl unlock, make emmcboot actually boot something, build a kernel that also boots... ;)

I wish I would have at least haRet to retrieve memory maps and lcd on sequences.. it's a shame microsoft messed it all...

Will retry the full unlock for the 800 tomorrow, see what I can do!
[Nokia Lumia 800] Bph&co:
Hi,

When you extract the loader from the esco file and manually put in the partition -

all works fine after restart. Editing strings or not important code does not prevent

the loader from working - nothing is checked on the loader before it gets execution

anyway.

But i just did a bad edit. In your case - maybe you haven't cut the correct part

before inserting it.

[Nokia Lumia 800] jessenic:
That is the N9 panel. Do they have the same panel in the Lumia 800? (I've always thought that they use a 854x480 for Lumia 800 too, as there are references to that resolution in the Lumia 800 firmware)
[Nokia Lumia 800] biktor_gj:
Yeah user CareDood tell me he swapped them and they both worked, so I disassembled the lumia and checked it out. It seems the trick on the Lumia is they use the lower part of the display to make the stupid buttons glow. What a waste of screen.

The problem is there are no available list of gpios, and the n9 code is hardcoded for the omap DSS, so porting it over to an entirely different architecture isn't easy, at least for me... I can't even make the keys respond :( well maybe I can, but I have no way of debugging it without a screen...
[Nokia Lumia 800] jessenic:
I'd like to see an image of N9 screen an a Lumia booted into WP7 :P But if you manage to get those things working, you would need to rewrite for Lumia 710 (different panel), right? And currently only 710 bootloader can be downgraded.
[Nokia Lumia 800] biktor_gj:
Unofrtunately I haven't got a 710 to try...

The first thing would be to check if the Lumia 710 can boot the LK bootloader with the lcd type set to MDDI (by default is set to spi). I have some memory corruption or some other kind of fault in there, but samsung's lcd doesn't seem to have much in common with other types of lcds.

It would be nice to know if it's a Toshiba or a Sharp panel, it would be easier to fix the lcd since half of the code is already written...
[Nokia Lumia 800] deylo:
hhmm im a bit lost. what do you suggest be done? because im getting the same error as you. have you found a solution to your problem?
[Nokia Lumia 800] beidl:
Yup, the 710 has got a different panel. It would be really great if someone could find out which panel it has, because I've tried some things which turned out not to work.
[Nokia Lumia 800] jessenic:
No idea if this helps, but this is on the back of the 710 screen:
[Nokia Lumia 800] ombadboy:
Done some digging around, and (I think) the Lumia 800 is part# MC2366.. Didnt find any further details about that however..

Hey guys, how can I check if my phone is fully unlocked?

@ultrashot: it finally booted!
[Nokia Lumia 800] beidl:
Install Root Tools and try to set some app's (like XapHandler) policy to trusted.
[Nokia Lumia 800] surya467:
ummmm...everyone discussing LCD panels and stuff!

lumia 800 , 2.4 LOCKED?? hello! :/

any update! pls let us know!
[Nokia Lumia 800] biktor_gj:
It says device incompatible, just like before... the rom has all the packages from ultrashot, sideloading works, but touchxplorer doesnt show any folder (like with interop)... so thats a no? Or simply the app refuses to work?
[Nokia Lumia 800] androin:
hi, am an open source programmer and a committer too...was able to access lumia 800 by the method mentioned in linux...if anyone needs help, please ping me...i can work on it further.

Have you already contacted the creator of OS Builder for help with the overflow error?
[Nokia Lumia 800] ombadboy:
Don't think I have a developer device.. Bought mine on release date from Phones4U.. Maybe it's an issue with the first batch they sent out? And can't be reproduced by later versions? No idea..

Also, I must note that I didn't update my Lumia to 12070 thru Zune but rather using the .cab from singapore using Heath's method.. if that makes any difference
[Nokia Lumia 800] surya467:
dont update to 10207, it doesnt allow this method!
[Nokia Lumia 800] beidl:
From all the posts I've seen in this thread, it does work as long as you didn't flash the update using Zune.
[Nokia Lumia 800] surya467:
no i havent..im using teh very first updated 10207 NZ firmware..i had flash it with this variant..and still it doesnt work...

lumia 710 on 10207 seems to b working...

i dunno..someone could just PM me who managed it..
[Nokia Lumia 800] biktor_gj:
Does anybody have a copy of that update package so I can see what it has inside? Maybe we can downgrade the bootloader or something...
[Nokia Lumia 800] ultrashot:
current public version of osb isn't able to build wmstore roms and isn't guaranteed to make template properly, unlike yet-to-be-released one.

//already suggested biktor to use it.
[Nokia Lumia 800] beidl:
If there's something in the air, please let me know, I'd like to get it working on the 710.

Progresswise I'm pretty much where biktor is.
[Nokia Lumia 800] Briefcase:
Here you go, this is the unbranded 12070 version (signapore):

[Nokia Lumia 800] ombadboy:
Yup, that's what am using and it's working perfectly..
[Nokia Lumia 800] biktor_gj:
Cant find any bootloader on the zune package, but while talking with ultrashot i noticed navifirn does download a new osbl, still havent checked it, but it could be that NSU/navifirm updated the loader and not zune?

btw, progress report: thanks to ultrashot I was able to decompile and recompile the rom and... it got stucked on the operator splash screen (before the nokia logo), but hey! progress is progress!
[Nokia Lumia 800] beidl:
In terms of u-boot: I'm pretty sure we can reuse a lot of these patches for our msm8x55 based devices:

[Nokia Lumia 800] ale07:
My phone allows me to access it, and it was updated to 12070 via zune. It was also one of the early ones, bought at phones4U, someone probably forgot to turn it off in the first few batches.
[Nokia Lumia 800] cdbase:
from which firmware what rev did you updated to 12070 (what was your earlier firmware)

edit.have you used mobileEx earlier? , it has nokia dload driver
[Nokia Lumia 800] _Madmatt:
Sounds promiseful! :) Keep up the good work!
[Nokia Lumia 800] Heathcliff74:
Trying to get it working on my NOKIA. Still no luck, so far. I downgraded from 12070 to 11500. Tried, no luck. Then downgraded from 11500 to 11451. Tried, still no luck.

I will now try NOKIA Care Suite and see if I can do something with that.

@biktor_gj:

dump is from phone with non-secure msm8255 chipset.

seems some lumias are not secure at all, seems some are secure - which could not enter that disk mode, but entering nokia dload mode instead.
[Nokia Lumia 800] cdbase:
**** i think i have a second option :/ but we don't know this for sure but im

afraid you're right :( maybe some update method leaves this option unsecure i've tried

cab method , NCS with navifirm 11414 unbranded retail mode italian, spanish> 12070 cab, and i get

hid device in dev mgr on win7,

on ubuntu i got nothing

and on other win7 pc i got dload nokia so i think that is caused by driver cuz when device is lack of driver it boots normally and exits dload mode
[Nokia Lumia 800] surya467:
Testing full unlock (XIP unlock etc) ??????????
[Nokia Lumia 800] Bph&co:
Hi,

Not for now. Just bought a new phone. I can try the Jtag, but not sure the

CodeComposer will install under 64bit windows, also will need driver for the XDS,

it's a long shot.

BR
[Nokia Lumia 800] Briefcase:
You could always install a 32 bits OS inside a virtual machine and redirect the USB device (most likely you are using a serial2usb converter right?) to this VM. With VMWare workstation I managed to still use some very old Texas Instruments calculator (connected through usb) software for example.
[Nokia Lumia 800] Bph&co:
Hi,

Yes, i will try. Vmware for sure can't handle complex USB transfers, but XPMODE

seems to work ok. The TI JTAG box i have is not simple converter, it has FPGA

and usb controller and lot more extra components.

Still the important question is if the jtag interface of the Lumia is locked or not.

Sorry guys for the noob question. I am not that familiar with WP7. I have my lumia 710 in an dev account and I want to ask, is full unlock and dev unlock the same thing? If not what is the diff between interop, full and dev unlock?

Again sorry if this has been asked many times but I cant check. Thanks
[Nokia Lumia 800] surya467:
but iv got a locked bootloader mate :/

i cant access qualcomm
[Nokia Lumia 800] vova1609:
Interop unlock - you can install wp7 root tools, etc. unlimited apps(can't install opera)

Full unlock - you can install opera mini, advanced config etc. unlimited apps

Developer unlock - you can install 3 apps(can't install opera)
[Nokia Lumia 800] mariosraptor:
thanks for the reply. on dev account, you mean i can deploy only 3 xap's to my phone? if so lol.
[Nokia Lumia 800] worraps:
3 xap's for student account. 10 xap's for the other one (forget the name).
[Nokia Lumia 800] mariosraptor:
thanks. you got your 1st thanks also. cheers

This subject has been dropped for a bit, but I thought I'd bring it back up:

What's the deal with why we can't flash the Qualcomm OSBL from the accidental 710 update to the 800?

I know the cert has the device dependent stuff in it, but even changing that apparently doesn't solve our problems.

Is it possible device dependent data exists in the mbn itself?
[Nokia Lumia 800] lilstevie:
changing it in the cert doesn't help because the signature check fails
[Nokia Lumia 800] Heathcliff74:
I'm pretty sure that Full Unlock is not working on that ROM then. You are only Interop Unlocked. If you have Interop Unlock, you are able to sideload WP7 Root Tools. On startup WP7 Root Tools tries to perform 3 different tests which all require Root Access. If all 3 tests pass it will continue. If one or more tests fail, WP7 Root Tools can't run and it will check to see if there are drivers present for which I have found exploits, that WP7 Root Tools can use to get Root Access in an alternative way. If that is the case WP7 Root Tools will start a 2-phase-installation procedure to install Root Access through driver-exploits. If WP7 Root Tools can't find such drivers (like on NOKIA and 2nd gen HTC's), it will show the Incompatibility warning.

I have tested WP7 Root Tools on a Full Unlocked Tango Rom on HTC HD7 and it works as expected. So, I'm pretty sure WP7 Root Tools is not at fault here. I think you need to check your ROM kitchen.

http://www.wp7roottools.com/index.php/guides/unlocks-explained

Ciao,

Heathcliff74

EDIT: I'm absolutely no ROM cooking expert, but could it be that the Full Unlock package you added to the ROM has not been added to the Sof/Cif lists? Or maybe in the wrong order? I believe the Full Unlock package should be added to the end of the lists.
[Nokia Lumia 800] ultrashot:
No, OSBuilder always adjusts sof/cif even if it wasn't edited.
[Nokia Lumia 800] Jaxbot:
But, why does the signature check fail?
[Nokia Lumia 800] biktor_gj:
Either way I added it myself... will check the xip package when I get home just in case...
[Nokia Lumia 800] suzughia:
Because is broken by editing.
[Nokia Lumia 800] Jaxbot:
The cert file is edited, though. And since the hash of the mbn isn't changed, how does the device/NCS know that we edited the cert file? Is the device header included in the hash?
[Nokia Lumia 800] Heathcliff74:
Ultrashot and me tested with a friend of Ultrashot, who has a Lumia 710 with unlocked bootloader.

Ultrashot made an osb-file and sent it to him with the same full-unlock-package you have. He made the NOKIA 710 ROM with Full Unlock and it works! WP7 Root Tools is running too!

There is something wrong/missing in your kitchen.

Ciao,

Here is lucifer3006's full unlocked ROM for Nokia Lumia 710.

Based on belgium Tango ROM with 24 langs.

1) be VERY careful!

2) BACKUP everything!!!

3) that's for Lumia 710

only

download

There can be some bugs, stock live id won't be saved for now. So, for testing only.

(sorry for nice font - I hope nobody will try to install it on Lumia 800 after that :D )

Guys i hope ya'll are also working for the Lumia 800..

I can see in this thread its not easy, but pls dont forget the Lumia 800 users :P

Im spectating this thread everyday in hope to see the words that the Lumia 800 can be unlocked for all now :P

Wish you the best ;)

and here is a tango rom for lumia 800

it isn't tested but normally it sould work

2) BACKUP everything!!!

[Nokia Lumia 800] lilstevie:
because the whole cert is signed, if you could just change any part of the cert it would be ineffective

Thanks!
[Nokia Lumia 800] mousey_:
Have you read the first post?

INSTRUCTIONS:

Requires an unlocked bootloader (a.k.a. qualcomm development bootloader).

Easy to check:

1. Turn the phone OFF

2. Then press and hold VOLUME UP + POWER until you notice a short vibration.

3. Plug in to the computer.

4. If the phone turns up in disk mode (USB Mass Storage Device), then you have an unlocked bootloader.

IF you're in Windows, it will ask if you want to format the disk. SAY NO OR IT WILL EXPLODE (it won't explode but you might break it)

If the device detected by the computer is Nokia DLOAD you have a locked bootloader and you're out of luck, at least for now.

I used 'dd' in Linux, I guess you can do it with Windows version too (http://www.chrysocome.net/dd) but it's more involved to find the appropiate partition:

To find the partition using Linux or OS X you can do:

cd /dev
ls

To see a list of partitions. For Windows you need to copy dd.exe into your system32 folder then from a command prompt run:

dd --list

To write your os-new.nb to the phone you'd do the following:

a) In Linux where X is the disk detected by your LINUX distribution.

dd if=./os-new.nb of=/dev/sdX9

b) In OS X where X is the disk detected by OS X .

dd if=./os-new.nb of=/dev/diskXs9

c) In Windows where X is the disk and Z is the partition detected by dd for Windows

[strike]dd if=os-new.nb of=\\?\Device\HarddiskX\PartitionZ --progress[/strike]

I'm not 100% on the Windows partition but when I did dd --list with my phone in bootloader mode I got this:

\\?\Device\Harddisk1\Partition0
link to \\?\Device\Harddisk1\DR3
Removable media other than floppy. Block size = 512
size is 15896412160 bytes

Which seems the right size and when the phone is removed I don't have a Harddisk1 showing any more. I take no responsiblity if this is incorrect and if someone wants to correct me feel free.

You've now written the ROM to the phone, to use the now Interop Unlocked phone you'll need to do the following to hard reset it:

1. Hold Power button for 10 seconds to exit Qualcomm's disk mode

2. Then press and hold POWER+VOLUMEDOWN+CAMERA until you feel the phone vibrate.

3. After that, RELEASE power button but KEEP HOLDING volume down + camera for five or more seconds. This will trigger the hard reset.
[Nokia Lumia 800] Ricehead:
Edit: Nevermind.

any advances for Locked bootloaders
[Nokia Lumia 800] meLIanTQ:
Hi,

Anyone check the RM801_Euro1_12070(059J3G0) ? Whats this Firmware?
[Nokia Lumia 800] mousey_:
For Windows:

does anyone know how to write the new-os.nb in Windows? I've done it on my phone using OS X but theres no detail for Windows.

The steps I have so far are:

1. Install dd for Windows

2. dd --list to see the partitions

3. Write to partition

Like I said in my previous post Windows shows me the following:

\\?\Device\Harddisk1\Partition0
link to \\?\Device\Harddisk1\DR3
Removable media other than floppy. Block size = 512
size is 15896412160 bytes

I think this is the total for the whole phone so could I do this:

dd if=new-os.nb of=\\?\Device\Harddisk1\Partition0
seek=524288 --progress

524288 being the beginning of the 9th partiton according to biktor_gj

Or is there an easier way of doing this in Windows?

I wonder what would happen if we tried

dd if=new-os.nb of=\\?\Device\Harddisk1\Partition8
[Nokia Lumia 800] biktor_gj:
@HeathCliff74, @ultrashot

Okay, maybe you guys can help me out with this:

Base Dump: clean, extracted from the 12070 image.

Added:

Dump\OEM\:

Pkg_FullUnlock

Pkg_InteropUnlock

PkgOem_XapDeployer

Dump\ROM\XIP:

Pkg_XipUnlock

On OSBuilder:

Settings -> Disable option: Enable ROM language selection

Settings -> XIP: Marked Rebuild -> Packages in ROM\XIP folder

Settings -> XIP: Disable Option: Do not move RamStart and nk RW sections

Settings -> Building - 2 -> While assembling use XIP: Ported/Rebuilt XIP

What am I missing?

Should I enable the option "Turn off sign/certificate checking in nk"? (edit: didn't make any difference)

EDIT: Dumped the resulted rom and every file is on it's place. Maybe is some registry key or something like that?

As far as I can see it is only available for the Lumia 800C. So you would have to do some customization in order to make it work with Facebook and Twitter. These services are blocked by a provxml. But back to topic.

I sent my Lumia 800 (with an open bootloader) in for a replacement of the screen. It had white dots when displaying gray/green colors. The repair tracking states that they also performed a software update and changed faulty parts. I'll report back whether the BL stayed unlocked or not.
