That question belongs to the Q&A thread. Please leave this thread for development only.

I will answer to your question though:

* UNLOCKED BOOTLOADER = NO NCS = YES CUSTOM ROM

* LOCKED BOOTLOADER = YES NCS = NO CUSTOM ROM

It's a personal choice :)

Any mod can cleanup this thread a bit please?

Now back to the topic:

Nokia OSBL: Unless someone can find a flaw in the RSA verification algorithm, there's no reason to keep trying to patch it, since you cannot upload it anyway.

I wouldn't even attempt to write lumia 710's bootloader to the 800. They share cpu, and probably half of the memory regions, but if there's a single GPIO/mem address, i2c call, mddi call or whatever the thing uses to access the nand chip different on the 710 it may very well leave the phone as a brick. The fact that they share the chipset doesn't mean they use the same pins for the same things. If it were for any other thing I would understand, if you want to try it from an unlocked bootloader by overwriting EMMCBOOT.MBN, or if you want to chainload it from LK loader fine, but please be careful if you're going to try to overwrite it directly on the flash since it's too easy to break it down and end up seeing yourself going to ebay to get a JTAG adapter and tapping the test points on the mainboard to attempt to recover it.

I wish I knew enough assembler (or any at all) to understand the loader and be able to guess if there's something wrong, but the truth is I don't. I can see the functions, I can find the verification functions, but don't have a clue on how to even know if there's a problem somewhere.

I would start looking at differences between updates to try to find a hole in the OS. After all, it's Microsoft, it's not like there aren't going to be any bugs on 1412 fixed on newer versions. Since we can downgrade, it could be possible to get interop unlock from there, and THEN, attempt to rewrite the Qualcomm loader back to the flash, from within Windows.

At least that's what I think...

@ultrashot: here you have my config for OSBuilder, you see anything wrong with it?
[Nokia Lumia 800] rescbr:
The FFU files should be flasheable using UpdateWP.

I did a quick look on those FFU files, and found that both _fullmodem.ffu and _FlashClean.ffu unfortunately contain Nokia DLOAD OSBL.

Edit: what's weird is that the oem.sku.xml file includes some conditions to package an OEM_7x30_BLDR (Qualcomm's?) if IMGBOOTEMMC is set. Which is set, according to the environment variables listed on the env.txt file.

The question is: are those FFU files built with IMGBOOTEMMC or they deleted the FFU files containing Qualcomm bootloader?
[Nokia Lumia 800] biktor_gj:
I got my flaw, WP7 Root tools working fine now on Lumia 800 too!

Uploading files to mediafire, will update main thread when ready

Thank you ultrashot for your infinite patiente.

In the end it was my mess, but it was a stupid mistake. When inserting packages into cif/sof, they got on the upper side of the list, and were being overwritten by the Core package in \SYS...

Btw, here is my DppImplant app.

Implants DPP partition with your stock Live Id to a custom rom.

Usage:

1) Put backup of the biggest partition to the folder with DppImplant.exe and call it "stock.nb"

2) Put "os-new.nb" there - target firmware in which you want to see your old Live Id.

3) Open DppImplant.exe. It will extract DPP from stock.nb and create mydpp.bin file. (After that you won't really need to have stock.nb in that folder).

"os-new.nb" will be patched.

4) Done.

P.S. if you open DPP using Notepad or any hex editor, you'll see saved Live Id.

Just a quick update that when trying to flash the RM801_12w07_prod_euro1_flash_fullmodem.ffu

I get this error ?

I have not edited anything either did Nokia F-Up there own Cert ? Maybe take a look at the cert file with this package see what they did wrong, Hopefully there is a vulnerability.

Any idea why they have 3 different versions of this ROM ?

RM801_12w07_prod_euro1_flash.ffu has flashed fine.
[Nokia Lumia 800] rescbr:
_fullmodem.ffu contains a bootloader (with "Nokia DLOAD" string) and AMSS.

My wild guess is that this is an updated engineering bootloader (hence the "Nokia DLOAD") signed with a cert that only engineering phones have, but someone has to check this.

What kind of filesystem is /dev/sdx9? I'm able to mount a saved dump of /dev/sdx3, but non of the fstypes are operational on sdx9 dump. My aim is to have a closer look onto the backup/restore process with Zune.

[Nokia Lumia 800] biktor_gj:
The fs is WMStore, at least for the first part. I tried to find Fat/exfat fs for userdata but afaik everything is stored in that format...

Its not mountable as is, but you can try to disassemble it with osbuilder's Dump Tool and see if you can find your files in there...
[Nokia Lumia 800] donpromillo:
Thanks biktor_gj,

my idea behind the question is the following, and I would to know, if my assumptions are logical:

I discovered, that in the backup process with zune all data sent between the phone and the zune-pc are scrambled before they reach the pc (I snooped the usb data stream and could find that the beginning of the usb data stream is the same as the beginning of the stored files in the zune backup folder)

So my assumption is, that scrampling the backup is done by phone. Furthermore, I can backup without any network connection, so all the things needed must be present on phone. If so, then if I'm able to identify the encryption process and it's parameters, I should be able to decrypt the stored files in zune backup folder too, provided, I were able to port that process to x86-procedures. And the last assumption: If I'm able to decrypt the backup files, it could be possible to edit these and re-encrypt the edited files. After that, they should be used to restore in normal restore process using zune.

Am I right?

DonPromillo
[Nokia Lumia 800] _Madmatt:
It seems logic. This way we could make fake backups containing Interop Unlock. But I'm afraid there will also be some sort of signature in the backups...
[Nokia Lumia 800] mousey_:
These are the files for the 12120 euro1 update:

http://xdafil.es/Lumia800/Dev/12120
[Nokia Lumia 800] donpromillo:
Yes, I think too thats there is a sort of signature. In the very first part of data.0.dat, you can find that Microsoft Primitive Provider with AES and SHA1 is used to create a CBC-Stream, which is stored by zune in the data.x.dat files. That means to me, either there is a static key used to crypt the CBC-Stream or a certificate. If a static key is used, it should be possible to find it, if a cert is used, the private key for this cert must be stored on phone, cause I do not need network to achieve a privatekey stored at MS-Sites to create a backup.

My first thought was, that the cert "zune-tuner://windowsphone/UUID... "in my private certstore on my PC is used, but my attempts to decrypt the backup-files weren't successful. But the explicit reference in the C:\Users\Myname\AppData\Local\Microsoft\Windows Phone Update\xxxxxxx - xxxxxxxx - xxxxxxxx - xxxxxxxxx\Properties\properties.xml onto this cert must have a cause.

So if I'm able to identify the mechanism, either cert or static secret, and able to export either private key or used secret, I should be able to create a valid signature for edited files too.

DonPromillo
[Nokia Lumia 800] _Madmatt:
True, my guess is that it should be a static key, because you should be able to restore your phone with the backup. If the cert is on the phone and you made your phone in a unusable state the cert may be deleted as well and the backup is useless. Just some thoughts though.

I think this is just some sort of identifier for the device. If you look at the name of the node in the XML document it is called DeviceUrlId.

I found that the backup consists of blocks of 4194328 bytes (every .dat file has this size, except the last one). So it would be very difficult to change contents of the ROM, because it is just split into pieces and every piece has a hash (Data.x.dat.hash). If you'd want to change contents, you would have to be careful with the splitted data, and you would have to generate a new hash for each piece.

Then there is also the C:\Users\MyName\AppData\Local\Microsoft\Windows Phone Update\xxxxxxxx - xxxxxxxx - xxxxxxxx - xxxxxxxx\RestorePoint\XXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX\Data\Manifest.xml file which contains data about every Data.x.dat file. It contains the size, and the index in the ROM (every DAT has an index, as they are splitted into pieces). There is also an DibrVersion key for every Data.x.dat file, but I have no clue on what this could be...
[Nokia Lumia 800] Briefcase:
Good thought!! As phone backups are unique to the phone that made it (you cannot restore a backup made on phone #1 and restore it to phone #2, even if both are, for example, Lumia 800's), i think there is no static certificate. Each phone stores it's own unique certificate to encrypt the data. It is true that zune only handles the encrypted stream of data, the phone does the encryption, i read that over here some while ago :). Best of luck!
[Nokia Lumia 800] Heathcliff74:
The device unique certs are stored in the MY-store on the WP7-device. They are refreshed about once a month (when they expire). There is a total of 4 certs in the MY-store. They are for different device-unique purposes. One of them is a zune-tuner cert.

Ciao,

Heathcliff74
[Nokia Lumia 800] donpromillo:
No, this is a certificate with a private key that could be used to encrypt something. Normaly the private key of that cert is not marked as exportable, so you can use this cert only on one computer, cause you cannot move the private key. I found a tool to export the private key as a first step. Now I'm on a search of information about the structure of the imgfs (which seems to be used in the backupfile and in the dump of sdx9 and how to extract that containers into a usable structure like direktories and files.

My attempts using OSBuilder and IMGFSTOOLS 2.1rc failed - any hints here?

Hi Heathcliff74,

are the certs on the phone refreshed every month with a new private key or refreshed using the same private key. If the latter is correct, then there is a chance that a cert is part of the backup encryption. If the private key changes, then it would impact, thats this is not a part of backup encryption, cause every backup older than the actual certificate becomes undecryptable, when the private key changes and no "master key" exists.

I searched a bit in rom-files and found OEM_7x30_MODEM.cab. It contains a file "modem" which seems interesting in 2 ways.

First:

I'm a lazy man and enthusiast of analogism and think, that developers at microsoft are lazy too and reuse code : Is it possible, that the procedure to pack the data for modem into one file and encrypting it is the same then in backup procedure? Look at the file which starts with a xml part, describing the crypting algorithm for the payload.

Second (is a guess, inspired by the ver.ver file which has a 7.35.00 in it, exactly like the bootloader version ):

the packed and crypted parts of "modem" are unpacked to partition sdx3 on Lumia as adsp.mbn, amss.mbn and emmcboot.mbn, which could be the bootmodes called when a backup/restore runs.

So my question is: Could someone with a full unlocked lumia search through the files on the phone for a similar xml file, containing configuration for image encryption and what programs or processes call them?
[Nokia Lumia 800] Heathcliff74:
I think these certs have only a public part. The encoding and decoding of the backup are probably working by getting the appropriate certs from an MSFT server at the start of an backup or restore action. The public certs are only for talking properly with different MSFT servers. I have not investigated this. This is just my educated guess. Maybe, if I have time, I will look into it later. If you have any specific questions that I may be able to answer, just ask.

Heathcliff74
[Nokia Lumia 800] Briefcase:
A few post earlier he said he could make a backup without a network connection (unplugging the cable). This would mean the certs do have the private parts included?
[Nokia Lumia 800] Heathcliff74:
donpromillo,

Are you sure you can do this without network? I'm pretty sure this is not possible. Maybe you had Wifi and 3G disabled. But you say you were snooping the USB connection while you were making a backup. At that moment, the phone uses your PC to get an internet connection too. :P

So if you really want to test if all info is on the device, you should also disconnect your pc from the internet. If you have your phone in airplane mode and your pc has both wifi and ethernet disabled, you will probably get an error if you try to make a backup.

Ciao,

If this is true - that means anyone who doesn't have a data connection can't make a backup of their phone... Surely Microsoft wouldn't allow that???
[Nokia Lumia 800] Heathcliff74:
Why not? When was the last time you saw a smart phone with no connection at all (not Wifi, no 3G and not ethernet over USB)??
[Nokia Lumia 800] lilstevie:
The backup is done in SCDL so wifi and 3G of the device would be disabled anyway
[Nokia Lumia 800] voluptuary:
So, I've built ROM's for the Samsung Focus and for the HTC HD2. Both of these have flashing tools to allow us to flash the fancy new ROM's we built to our phones. If we have the unlocked bootloader can't we just rebuild the esco and flash that with QPST? Or is there something I am missing? Building the Lumia ROM in OSBuilder seems to be the same as other devices. So if I just take the .nb that is built and rename it boot.img then add that to a zip and then rename that zip bla_bla_rom.esco will that not work? Or is there something more? Does the Qualcomm bootloader still need signed files of some sort? I ask this becuase if we can do it this way then we won't have the Live services activation issues as well ass the other odd problems plus it is just way more end user friendly.
[Nokia Lumia 800] tjramage:
Good point. But I figured there is a possibility someone may not have a data connection and need to create a backup... If it was me, I wouldn't disallow people in those circumstances to backup their phone... But maybe Microsoft is different.

I may be wrong, but I think Heathcliff74's point is that the cert-checking is done before the phone enters this mode.
[Nokia Lumia 800] donpromillo:
Hi Heathcliff74

you are correct, I forgot to disable the wlan on phone, so at the start of WP7EaSYbackup, it was able to connect to MSFT. If I disable all, even 3g/2G Connections, then Easybackup stopps working, in the logfile you can see that it could not connect to the updateserver. Nevertheless, I'll investigate soon, what the Updateprocess is talking to MSFT.
