CG36, CG43, CG44, CG46 and CG52

[rasputin007]

I have managed to open CG36, CG43, CG44, CG46 and CG52 and their folder and files are in this Download ~48 MB
It is the V8 China Flash, but could be done on any other flash.

hey raz! thanks for the help. Anyway you can make a FB profile for Z6? Should be very similar to V8

How to get the filesystem of a CG for V8/Z6

You need:
One firmware
SBF Recalc 1.2.8
One Linux OS with squashfs kernel support (I use Debian cos I can select squashfs to be installed and the rest is done by Linux, other distros might require to recomplie the kernel in order to add squashfs support. It is not yet part of the kernel.)

First you split the firmware with SBF ReCalc 1.2.8 and shorten the names of the CG.smg files to CG46.smg or something else simple or you could use SBF ReCalc 1.2.8 for Linux and you could do it all in Linux OS.
Next you are in the Linux OS (I logged in as root, but it might work as well as normal user) and create a new folder for eacg CG you want to mount (e.g. /V8/CG46, /V8/CG34...). I have copied the CG*.smg files to my home directory, but that is not absolutely necassary.
Now open a Terminal and enter the following command line:
mount /"path to CG.smg file" /"path to folder where you want it" -o loop -t squashfs
In my case I had the CG46.smg in my /root directory and the folder where I wanted it to be mounted is /V8/CG46, so my command line would be:
mount /root/CG46.smg /V8/CG46 -o loop -t squashfs

And that's it!
Now you can browse the mounted CG.smg file. You will see more folders and files then in the download I put up, that is due to the fact that empty folders and symlinks are NOT included in a zip file.

Excellent work! It would be interesting to see what we can get out of this. Again great work.

I am afraid to say I do not make fb3 profiles, that is Psycomorphers subject. On the same note it was Psycomorpher who asked me if I could mount the CG files cos he did not have a Linux OS (yet!).
From what I have seen so far is that the V8 runs a 2.6.10 kernel and has telnet installed.
Attached is a service file that lists all ports, from CG36/etc.

Correct its kernal 2.6 but the only thing is that the retail versions dont have telnet or better said USB-NET disabled. Proto-types like the one i had a few months ago had the option. So my ideal is to create a patch based on the proto-type software.

I noticed that I can not mount the CG's that I have created by using fb3 and the V8-fb3 profile. Those backup CG's are not squashfs, which might explain why flashing backups ends in BL.
There is only one way to get our greedy little hands on the V8 software and that is via direct connection.

it is only list of standard ports which exists in all linux distro.

i'm newbie here,
is it possible to mount those CGs and make modification?
how to apply modified CGs to phone?

You can change any file in the mounted filesystem and create a new CG.smg with "mksquashfs" command, but I doubt if it will work cos there is no digital signature, which seems to be in every CG and without those the V8 just will start in BL (bootloader).

UPDATE: you can NOT change any file in the mounted squashfs filesystem because it is a read-only filesystem. Sorry got that wrong.

I'm no expert but looks like a symlink to /bin/busybox. So does this mean telnet is there just not on?
