Hello,
I have extracted the CGxx.smg file out of an sbf-file (android 2.3.6).
Now I am trying to get the content of the CG39.smg with the command "unsquashfs" but the result is only the error: Can't find a squashfs superblock on ...
So how can I extract an smg-file?
EDIT: http://sourceforge.net/projects/ext2read/ works fine with Windows and the CG39.smg

Use the attached unyaffs for system/CG39.
Please note that you have to set permissions inside the updater-script if you want to make an update.zip.
As far as I know Linux can store permissions inside an zip-file but I'm not sure.

CG64.smg & CG65.smg: partition tables that you can open using fdisk/sfdisk
CG33.smg is a CDROM ISO file!
iirc one or two of them are the splash image (not 100% sure now)

System.img to be restored with Nandroid? If yes you have to extract all files with ext2reader then use mkyaffs2image to build system.img.

with mkyaffs2image its jus showing me a cmd windows for some less thn 1 sec and its jus goes away...please upload the version you are using...also let me know if it needs any prerequisite software to be installed.
It's because mkyaffs2image is a command line app, just like in the DOS days... To use it you should open a cmd window (type cmd at Windows menu and press enter), go to the directory right before the one you extracted files (you use cd "dirname" to enter in a directory and "cd .." to leave it. So when you are in the directory right before the one in which you've extracted files type "mkyaffs2image CG39extracteddir system.img"

ok last doubt...after creating system.img can it be restored via custom recovery..??
how to add md5 check sums for that so that custom recovery can identify as proper nandorid..!!??
rachit2588 said:

You welcome!
Sure you can use it with nandroid, you must download md5sum.exe, place it together with mkyaffs2image, after you used mkyaffs2image then type "md5sum system.img" and it will generate checksum. Create a file called "nandroid.md5" and paste what md5sum returned. You can open a nandroid.md5 file of another backup and you'll understand better how it's done..
excellent..i got it
@danimagrin help me how to add root files if our cg39 image is unrooted..??

I know how to do it on Linux, because you've to run chmod and chown to set su and Superuser.apk permissions. I'll see if it's possible to do it inside Windows and I'll answer you asap.
Where did you get mkyaffs2image for Windows? Are you running it with -f flag or not? Have you already made an image and restored it and did it really work? I'm afraid if will not work because of the same problem above...

I'll test it as soon as I get home and then I tell you!
i understand that to create a fixed SBF i need to remove CG31 and CG39 and repack. the question is, how can i get a nandroid of the system SBF without flashing the full SBF?
so is there a way of converting the CG39 into a nandroid img? or is there any other way to do it?
i know there are nandroid backups of different SBFs but i have localised SBF that i want to use and i dont want to lose downgrade-ability. what to do?
You can get the CG39.smg file and copy it to a linux box.
Then you create a folder inside the /mnt folder
Code:
mkdir /mnt/GC39
.
Then you can mount the CG39.smg as a loopback device:
Code:
mount -o loop /location/to/your/cgfile/CG39.smg /mnt/CG39/
Then you can go into /mnt/CG39 folder and copy the contents to anywhere.
After you'll need to repack it on a system.img file in order to make a nandroid restore.
i will try that, thanks!
i've done the above, and used "cat" command to create the .img file, strangely the smg file and the cat output .img are exactly the same size in bytes.
is it safe to nandroid restore the .img file?
can anyone tell?
im going to see if using dd command makes a difference.
Edit:
using dd command i got also the same size in bytes as the original smg file. this either means that i wont be able to downgrade or CG39 file doesnt include anything to block downgrading.

seriously? how could you expect otherwise?
you practically did the most complicate way of copying a file.
would you expect the file to change by doing that?
you need to do use makeyaffs2image
Hi guys,
this is a big tutorial for advanced users on how to edit LG Firmwares.
This could be usefull to change recovery included, root the bin or give a try to
change bootloader to make su760 ics on p920 work.
First download a bin or a kdz file:
http://lg-phone-firmware.com/
Then download the attached zip file and unpack it somewhere on your
windows pc.
Put the downloaded firmware in the same directory.
If you have chosen a kdz file you have to unpack it with LGExtract.
Ope up cmd and go with cd to the directory where all the files are.
Then type:
Code:
LGExtract -kdz *nameofthekdzfile*.kdz
upack the new .cab file with winrar or something like that, then run
LGExtract -wdb ***.wdb ***.dll
Click to expand...
Click to collapse
replace *** with the name of the files that you have unpacked
Now you should have a Folder caled BIN.
Use cd to enter that folder.
Run in cmd:
Code:
copy /b "LG****_AP[*].bin" "LG****_AP.bin"
Replace **** with p920 or su760 related to wich firmware you have downloaded.
Now use explorer to move the LG****_AP.bin in the folder where all the .exe files are.
Extracting the bin
Run in cmd
Code:
extract.exe ***_AP.bin
At first you will see all the partitions in the bin and their offsets,
then the tool will extract them to .img files, stay tuned this will take some time.
Root the system partition
You can skip this if you just want to replace a partition.
Rename the extracted sstem partition from something like "7 - system.img" to "system.img"
Download this:
http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip
and put it together with the system.img into a linux distro.
In linux unpack the zip and copy the superuser.apk and the su file
in the same directory with the img
go with the terminal in the folder with the system.img
and run:
Code:
sudo mkdir temp
sudo mount -o loop system.img temp
sudo cp superuser.apk temp/app
sudo cp su temp/bin
cd temp/app
sudo chmod 0644 superuser.apk
cd ..
cd bin
sudo chmod 6755 su
sudo umount temp
Copy the image back to windows.
Replace a Partition
Install winhex or an other hex editor.
Open the downloaded or extracted bin.
Go to offset that extract.exe showed you,
and select everything to the end of the partition and delete it.
The end of the partition is the offset + size of extract.exe showed you.
For example:
If the offset of the system partition is 00DA0000
and the size of is 2BC00000 the end of the partition is DA0000 + 2BC00000 = 2C9A0000
now open up the image you want to replace i with in hex editor,
select everything go back to the offset of the partition in winhex and paste it there,
just save it and you have your new own bin file ready to flash with LGFlashTool.
Hope this helps you, please post if you didn't understand anything, I forgot something or something is wrong.

i need to figure out How to differentiate between Sparse Img and raw img because i want to mount a raw img so that i can edit the apks and jar files in it.
i have a file named system.img but whenever i am trying to mount it using the command "sudo mount -t ext4 -a loop system.img outout/" i am unable to get the apks and jars to edit.
i also want to know how to make a binary file executable.
in short i want to get the system folder which contains the framework,apks,media,bin,xbin,usr,etc...folders and i am a noob in ubuntu. I have the rom inside which is the system.img but i dont know how to extract the system.img and weather the system.img is in a raw stste ot sparse state and i have all the binaries in that same folder such as simg2img,img2simg,make_ext4fs,etc.... but i dont know how to use the binaries.
i am using a VirtualBox with windows 10 as host and Ubuntu 16.04 as guest.
So can anyone help me with this.
Hello,
Just wanted to ask if there's a way to extract specific application and its data from TWRP backup?
What are your suggestions? I have tried opening zip but I didn't have luck finding what I was looking for.
Thank you in advance!
If you look at the TWRP logs it indicates that it uses tar to create the archive file.
All you have to do is rename the .wim file to .tar.gz, then extract the file.
Related Windows command line is
Code:
tar -xvzf filename.tar.gz
