This might be useful to someone for development purposes. I split the fire boot.img that I extracted from the 6.1 update.
This zip file contains boot.img-kernel and boot.img-ramdisk.gz

Is there a newer version of DumpROM exist to unpack ROMs for Magneto devices?
The original dumprom hangs on the .nbf files extracted from ROM upgrade utility.
Hello guys,
I am trying to extract system.img.
I got system.img from this file
RUU_Vision_HTC_ARA_1.83.415.2_Radio_12.28e.60.140f_26.04.02.17_M2_SF_release_168396_signed.exe
I tried unyaffs with no luck. I actually tried to use unyaffs on some other system.img and it worked.
I get this
0 [main] unyaffs 4172 exception::handle: Exception: STATUS_ACCESS_VIOLATIO N
1094 [main] unyaffs 4172 open_stackdumpfile: Dumping stack trace to unyaffs.exe.stackdump
Please help
hey,
maybe you should try this in the android developement forum. here are only g2 users and i guess in the developement forum there might be more ppl who could help you with that!
Unyaffs is used on img files created during a nandroid backup.
For most img files contained in an RUU, it's simply the filesystem it would normally be on the phone, in this case ext3. You need to mount or open the file with the ext3 filesystem.
I found ext2explore tool much easier on Windows.
Download
Edit: Didn't realize it's old thread-
Technically i have to give credit to scott crossler
www.scottsroms.com
for showing me the method
and then i came upon turges
faq
Thanks Turge and Scott and whomever created these blobpacktools
but since i keep getting pms
and im sure you do to

Here are the steps for repacking the boot.img. Some involve running the commands via cygwin, others involve running them via the Windows Command Prompt.
The instructions for installing cygwin, extracting and repacking the boot.img were found here: http://www.freeyourandroid.com/guide...ot-img-windows
Once you have setup cygwin, extract the attached files in a folder under your "home" folder in cygwin.
Also unzip blob tools into the same folder as your boot.blob
1.
Code:
copy boot.blob to the same folder and run the following via
the Windows Command Prompt to extract the boot.img from the boot.blob:
BlobUnpack.exe boot.blob
ren boot.blob.LNX boot.img
which will create boot.img
2.
Code:
From the cygwin bash terminal window,
switch to the same folder and run the following
to extract the ramdisk from the boot.img:
./extractboot boot.img
You now have an out/ramdisk folder
that contains the files you want to edit.
3.
Code:
Once done, repack the ramdisk and kernel into boot_new.img
with the following command (via cygwin once again):
./packboot
4.
Code:
then from the Command Prompt repack boot_new.img
into boot2.blob using the following:
blobpack -s boot2.blob LNX boot_new.img
5.
Code:
You can now flash the boot.blob to the staging
partition via a command in updater-script:
Code:
package_extract_file("/boot.blob", "/dev/block/mmcblk0p4");
or by using adb while in recovery/android:
Code:
dd if=/sdcard/boot2.blob of=/dev/block/mmcblk0p4
Lastly the rundown is like this
if you want to take a ota blob
and extract the contents for a raw base
and a raw kernel
1
take the ota and extract the blob file and place
in your folder with blobtools
2. then run
Code:
blobunpack.exe blob
Which now creates
Blob.APP =System.img (can be renamed system.img and unyaffed in the kitchen)or straight cygwin
Blob.sos=Recovery Img
Blob.Ebt=Bootloader information
Blob.Lnx=kernel (can also just be renamed boot.img and unyaffed in kitchen)
Blob.pt=Partition info
so to repack lets say your custom remade image
and your custom kernel
and a recovery of your choice
run
Code:
blobpack.exe -s blob lnx boot.img sos twrp.blob app system.img
then simply take the blob replace in the ota file
and flash in recovery
and it should flash a rom packed as a blob
Hi!
...also you can flash the new boot.blob via fastboot mode
>fastboot-i 0x0B05 flash boot boot.blob
:good:
Call me stupid, but what does repacking the boot.img do? I never pm'ed you, but what would we gain from this. a lil lost
unpacking a boot.img allows you to take a stock already built kernel
and make specific changes to the ramdisk
more specifically
default.prop
can make kernel insecure
debuggable
bootanimation enabled
blah blah blah
and init.rc
but also
cardhu
and goldfish.rc
and init.trace
and init.usb
then repacked and good to flash

Hi!
For a linux (Ubuntu) machine you can easily unpack blob.APP
> sudo mkdir mnt
> sudo mount -o loop blob.APP mnt
- now in your mnt directory , you will have /system ! :good:
Hi,
My TF300tl can't unlock bootloader. so can I use this way to pack custom ROM ( cm11, liplop...) as official ROM to flash for my tablet ?

I wouldn't think so, as the ROM would have to be signed to be official
Found BOOT-EXTRACTED folder, checking contents ...
Found boot.img-ramdisk
Found zImage
Working folder found
od: boot.img: No such file or directory
Compiling mkbootfs ...
Error: mkbootfs not successfully compiled!
Press Enter to continue
how to solve it ??

I need the official tmob noteII jb 4.3.1 kernel in tar or zip can anyone give me a link please
or latest official kernel
(Assuming you're running under Windows.)
Download the complete stock ROM from sammobile or the like. You could also get the boot.img from a repacked zip here, but YMMV.
Extract boot.img from the .tar.md5 file with a compression utility that handles tar archives, 7-Zip works well for this. (The error message about the end of the file is normal, that's because the MD5 hash isn't part of a normal tar archive.)
Get cygwin, namely its tar.exe command. With boot.img in your Cygwin home directory, from the Cygwin shell run:
tar -H ustar -cf youroutputfilename.tar boot.img
As an aside, my Windows-based setup to make Odin-flashable images is fancier than that. I've added the Cygwin binaries to my PATH environment variable (jury is still out on whether that's a good idea overall, but it works for a number of tricks) and I've created a script named tarodin.cmd in that directory which contains the following command:
tar -H ustar -cf %1 sboot.bin tz.img md5.img efs.img m9kefs1.bin m9kefs2.bin m9kefs3.bin param.bin boot.img recovery.img system.img modem.bin tombstones.img cache.img hidden.img userdata.img
The missing files just cause an error to show but the file itself works perfectly. I haven't bothered adding the MD5 hash, but it could be done.
The other way is to take a working t0lte kernel zip and substitute the boot.img in it then flash through recovery.
Good luck,
Darkshado
Got Kernel working

Thanks bud used the Kernel and subbed it in zip that did the trick God Bless
