Need help to find BoxID in oscam config in DM500s backup.img

Hi.

This is probably an incomplete and corrupt file (compressed filesystem - CramFS).

It is not possible to unpack it with the help of "7z" archiver and also with "fsck.cramfs" command:

root@vusolose:/media/hdd/e2# 7z e dreamup-backup-dm500s-TE28F640.img

EDIT:

Maybe you could use the "binwalk" tool https://www.refirmlabs.com/rev…rs-firmware-with-binwalk/ , but unfortunately I don't have a full-fledged Linux machine available at the moment. I only have a depleted set top box with Enigma, where the binwalk tool does not exist on Enigma's feed servers :).

Yes, but the configuration files for Oscam just exist inside. So we need just "extract" them from this compressed CramFS :).

IS CORUPT FILES ARHIVE !not work with enithings ,and belarus_rusian i dont now ,sory

Some record of the "oscam.conf" string exists there.

However, this will only be the table of data-locations in the filesystem. I dont know these Linux file systems at all, unfortunately. I grew up on FAT and NTFS :).

your pasword is not default? you remember it?

This is not my backup, it's the joan789 's backup.

yes ,is pasword protect ,if is in rusian language ,what pasword have?

Quote from joan789

dear sir!

wish someone can find the BoxID in oscam config in the attachment of dm500s' backup.img with dreamup.this dm500 is broken so i can't boot

to get the BoxID,i need it to read card in other dreambox.I can open this image in ultraEdit but don't konw how to get what i

if you have changed pasword on dreambox ,put hire!

in english,not russian and the password is default, root / dreambox

ok try open with notepad+++ and see a lot null ,when i change in cirilic ,character is clear,

try Peazip and ask for pasword ,put your pasword and maybe is open,is corupt image/backup

Because your notepad++ is weird or misconfigured. PeaZip archiver is used for other purposes ... these CramFS formated files can also be opened in a 7-zip archiver. Simply put, PeaZip understands this file as a standard archive (see file properties). Notepad++ understands it as a text file (with detection of an incorrect code page, as the format of the binary file is unknown / incorrect according to Notepad++).

Use only proven tools for working with compressed CramFS !

more easy if this image can put in a dm 500 s to get data from files

if somebody have a dm500 box

Hi. You don't need a DM500 for that. Also no other set-top box. This image should be mountable as a virtual disk / filesystem under all Linux systems. Well, if it's damaged, it probably won't be possible.

not work ! i install on dm500s and is corupt ,maybe with linux masine ,decompress file and see config oscam

As I wrote, it will probably not be possible.

Although I don't know this compressed file-system (CramFS) from Linux, the file information, in this short "cut out" firmware, is probably just a reference to the location of the disk where the data is to be stored. However, part of the firmware (disk) with the stored data of these files is probably missing - it is not the complete firmware that is backed up, but only a short part of it.

So it probably won't be possible.

But maybe I'm wrong. I don't know CramFS well, as I wrote.

if you qwent desamble on linux image ,put one good loader dm500s and after install on one dm500s ,is a lot work,maybe?

I dont know, sorry :).

I have tried to open this firmware twice already - first in a set-top-box under a depleted Linux, with the help of "fsck.cramfs" tool and then simply using a "7-zip" archiver under Windows OS.

But I haven't tried the third method, which I also mention above, because I don't have a full-fledged Linux - the necessary "binwalk" tool:
