dgs.img file (CSC) what's inside?

Hi Guys,
Looking at the different OTA packages available, and the files provided with Odin in order to flash back to stock the Nexus S, I can see that there's a file called "dgs.img" that is never reflashed/touched using the OTA files provided by Google.
In order to reflash dgs.img you need to use Odin and select the CSC part.
Do you know what's inside that img?
Looking at the fastboot screen of 2.3.3 I can see an info called "CARRIER - ", the American T-Mobile Nexus S has "TMO" written on it, the I9023 sold in Europe by Vodafone has "Vodafone".
Reflashing the CSC with the file provided in this forum (as far as I know, given by a Service Centre in UK), the Carrier info become "EUR"
Is there a way to look inside that image and have a look at it?
thanks!
Cheers,
T.

Now I have the same question now...Since I can't unyaffs it...

OK man, I figured it out~after a showering time ^_^
Use notepad to open the dgs.img, the world is bright!~~
How I figured this out? Firstly I unyaffs-ed the img and got the note" broken img file", and I am quite puzzled with the size, 1k...seems a bit too small for a img?
after that I read something about csc changing under I9000~
And in the end, when I was showering, a thought just came to me: this is not a img file, just a text file.
I tried, and I am right!~
Cheers

OK, I successfully changed the carrier info to TMO. Open this file in Hex Workplace and change the EUR numbers to the 54 4D 4F, and everything is fine now~~
The reason why just can't edit under notepad is because it will change the 00 between two TMOs to 20, so this leads the problem.

yes... just guessing what's the difference for example between the EUR and VDF version in terms of phone behaviour... maybe OTA update availability??

[Request] Any Brazil open device user

Ok, this request is for ALL the 920h/925/925G users (anyone with an 850 UMTS band). We need ANYONE from brazil with a device that has or was going to update to the Brazil V20a to enter the following link and get us the bin format link back as the bin format firmware is what we need to get JUST the baseband. Elsewise we may need to flash the WHOLE firmware and bin flash downgrade to root and recovery partition. I'd rather not put more people through this headache....
Link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/cs_auth_model_check.jsp?esn=[YOUR IMEI HERE PLEASE]
The link you are looking for is similar to this one.....
http://csmg.lgmobile.com:9002/ezls/...IN_LGP925AT-00-V10e-310-410-AUG-10-2011+0.ZIP (this is the BIN firmware for AT&T's stock firmware.)
Thank you guys and remember, you're doing this not only for yourself, but for the community as well.
Note: We already have the kdz (http://csmg.lgmobile.com/swdata/WEBSW/LGP920H/ABRAML/V20a_00/V20A_00.kdz), we need the bin.

I tried to do it but I get only a blank screen on explorer and some information about my serial number and imei on Chrome. No links were there.
any guides so I can help?

Thank you.

I got the same result. If you explain how to put the URL together with the info I got, I can help you. Thanks.

That's my result:
LGP920H 6BRAML 109BSZD011069 20110912

are you try another browser? firefox? IE??

Using another browser won´t help, but the file is in fact a XML. Use view source to see it. It´s a list of fields and values. We just need to know how to use this info to build the BIN file URL.

It's being done right. With the information provided, I was able to try a few things, but I was not able to find Bin files, but only KDZ. I've also reached out to others in the community for possible outside the box root options. I'm not making any promises, but I'm resourcing. I'm sure we'll find a way.

[TOOL/REDIRECT] LGExtract

Hello LGP920 users, I don't have this phone (I own a 970), but, I'm working in a tool that can help you guys too.
The purpose of the tool is to extract the files .bin / .fls from the .kdz files, to use the tool SmartFlash.
I don't know if this kind of topic (duplicated) is allowed, but, is a tool for "all" lg phones.
For now its really useful for P920 and P970, because we can flash files bin / fls with SmartFlash tool.
Other phones has different file structures...

I'm not copying and pasting the text here, because I'm editing the another thread.
Please report any errors there.
Thanks.

Thanks, certainly these tools are useful for developers.

Did you tried extract another file? or a kdz?
Your problem seems to be with Microsoft Enhanced Cryptographic Provider.
I will made some changes at the code to handle errors better and provide more details.
You should wait for the next update.

With LGExtract, roms can be prerooted even if the Megatron root exploit is fixed Thanks a lot

Hi guys, going off another thread I didn't find this thread using search so just popping in the search word extractor so the next poor bugger doesn't get flamed for not using search
Tool is great and will help a lot when we get the next rom we can root but has a better baseband

If you can find out, could you post what modem/baseband processor is used in these devices: P920, P925G, P970 ?
This info should be available in the Service/Hidden Menu and in the modem firmware file. Look for "Qualcomm", "Infineon", "x-gold"...

[Q] Debrand Dead End: Nokia Product Support Tool V5

I've downloaded an unbranded stock UK ROM (i think) for a Nokia 1020 64Gb to replace the O2 rubbish.
It is file
RM875_3051.40000.1345.1003_RETAIL_eu_euro1_212_03_336753_prd_signed.ffu
It was automatically downloaded to C:\ProgramData\Nokia\Packages\Products\rm-875
I try to 'make' Product Support Tools for Store 5.0 find the download. It will not.
Regardless of which folder I place the download in (and alter the supposed location path) all the Recovery Tool sees is the software
already installed on the Nokia 1020 - filename. It defaults to this file.
RM875_059T1Z9_3051.40000.1345.1003_062.vpl
This is the nasty O2 branded crap already on the Nokia 1020 and all it wants to find.
Have I just downloaded another O2 branded rom ?
Dead end and out of ideas.
All answers on a postcard please to Muppet The Wonder Dog.
Do I have to remove something that makes it default to the installed
version of software ?
Thanks in anticipation.

The download was successful. The 059T1V6 files are downloaded to C:\ProgramData\Nokia\Packages\Products\rm-875. I used NaviFirm+ to download.
Alas, Product Support Tool for Store 5.0 does not want to locate the files. Why ? I have moved the files (and changed the path) to different locations in an attempt to persuade the software to locate the 059T1V6 files. But NO ...it will not.
Every time I try to change the address path to where I've moved the files is adds "\Products" to the path address. Not helpful.
When I create the path it thinks it wants .C:\ProgramData\Nokia\Packages\Products\rm-875\Products...and place the files in this folder..it still refuses to locate the files.
Going round in ever decreasing circles.
Thanks in advance Anaheim.

No, use Data Package Manager for DL your FW

The reason I paid & used NaviFirm+ to DL the FW is the DL worked.
I am unable to get Nokia Data Manager to accept any text entry in any of its fields to start a DL.
I am unable to get Nokia Product Support Tool V5 to see/locate the (apparently) identical FW downloaded via NaviFirm+ to start the 'Recovery' process.
I'm on fully patched W7 (x64)
It's a mystery.

If you are in offline mode in the Data Package Manager (and according to the screenshot, you are) you can not DL the ROM.
Similarly for Product Support Tool, why did you connect directly your Lumia?
Follow the tutorial that I provided and you will get there.If you are unable to properly follow the steps (in most it's extremely detailed and with the screenshots), sorry but I can not help you.

As I said the problem is not in the downloading of the ROM.
It was very easy in NaviFirm+. I recommend the software for its simplicity and ease of use.
I have identical ROMs downloaded via Nokia Data Package & NaviFirm+.
The problem appears that the data path in Product Support Tool for Store V5.0 appends as a suffix '\Products' to the data download path. This is not the default path given from the Data Package Manager. The path is not user editable. If I create the additional folder and move the files to the folder it says it is looking for.... the Nokia package still fails to locate the FW it is trying to Recover. There are no screenshots to illustrate any error message. There is no error message.
I appreciate that it is very difficult to convey the exact steps in unambiguous English. I have been very fortunate in both multiple JailBreaks and the application of Cyanogen Mod to a collection of Samsungs..

To delete.

all paths added have the sub-folder ' \Products
' appended to the text string. I am unable to edit the path name. Just add another.

One possibility would be to use thor2 to change the product code on the device, then let the WDRT do its job.

How can I unpack .mbn files?

Hello all, I am trying to unpack man files to add volte support to a device that has all the hardware needed, but it is not enabled in software and I would like to try and change that. From all my research the files I need are all in the baseband and in .mbn file format, but I cannot find out how to unpack them. Any help would be appreciated!

ghidra or IDA

I'm more conversant with Qualcomm ELF files, hashing, signing and certs.
These seem to have replaced the older MBN.
MBN files are signed. If you mod you'll have to work around this somehow.
See: https://github.com/openpst/libopenpst/blob/master/include/qualcomm/mbn.h

I see. This device is quite old and well, to say the least it isn’t an android device either. I’m assuming I would need to find a workaround for this even as it’s running an os that’s nearly a decade old now?
I know that the carrier bundles on this device are signed as well, but people were able to get around that, and this chip was supposedly made with the hexagon DSP and Qualcomm has documentation on how to program for this specific chip/version

Maybe it’s my first time even hearing of either of those programs and can’t even get one of them to launch without insta crashing, and the other spitting out an error whenever I try to unpack the files.

no problem. just 10 year studying stuff and try again

Hi,
I've probably managed to reverse engineer the MBN. I was able to create my own MBN and load it back.

they are only ELF files packed in an image, aren't they?

yeah ELF files, with 3 segments. I'm not sure about my knowledge about ELF vs MBN, but I've managed & have a program to extract $ repackage back. I've tested it on Pixel 2 XL and it's working (added support for my country).
