This is the dump from my device just thought you all may want it, if anyone knows how to pull the radio and boot.img please PM me
whats commands did you run to dump you partitions?
** EDIT **
Nevermind it seems as you just pulled /system and packed it up...
Anyone know how to pull partitions to *.img files?

can't you just "cat /dev/block/mtdblock# > image.img
(substituting the # with the desired number of course)
Or would Root be required first?

Yea I think permission denied
cat /dev/block/mtdblock3 > /sdcard/image.img

I have already successfully removed the boot and shutdown animations (incl. sound) via "adb shell" commands:
Code:
su
mount -o remount,rw /dev/mtdblock3 /system
mv /system/media/bootani.qmg /system/media/_bootani.qmg
mv /system/media/samsungani.qmg /system/media/_samsungani.qmg
mv /system/media/video/shutdown/shutdown.qmg /system/media/video/shutdown/_shutdown.qmg
mv /system/media/audio/ui/PowerOff.wav /system/media/audio/ui/_PowerOff.wav
mv /system/etc/PowerOn.snd /system/etc/_PowerOn.snd
mv /system/etc/PowerOn.wav /system/etc/_PowerOn.wav
mount -o remount,ro /dev/mtdblock3 /system
exit
or just download the attached shell script and execute it as su:
adb push nobootani.sh /data/local/nobootani.sh
adb shell
Code:
su
cd /data/local
chmod 777 nobootani.sh
./nobootani.sh
exit
Btw the tablet now boots much faster.
But the boot splash screen from Samsung is still there.
EDIT:
I found out that the boot logo is actually a JPEG image located in the Secondary Bootloader (sbl.bin) on partitions bml4 and bml5 (both are identical on my Tab).
The partion layout seems to be the same as for the Galaxy S series:
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S#Modifications
(here you can also find the secret codes to check firmware etc.)
This command gives the partition info:
cat /proc/LinuStoreIII/bmlinfo
To dump any partition (e.g. SBL) to SD card:
dd if=/dev/block/bml4 of=/sdcard/bml4_dump bs=1
I attached the extracted boot logo.
Thanks xdadevel,
Followed your instructions above and it worked like a charm - my Tab boots up MUCH faster now.
I think to remove the Samsung boot logo you would have to edit something like init.rc in the bootimg, repackage it, and then copy it across.
Im trying to do this and get
Can not mount permission denied.
Failed for bootani.qmg, Read-only system file.
Any ideas?

I've been reading about the methods for other Samsung devices, such as:
flashing a PDA tar with Odin
fastboot flash splash1
packing the logo png as an update.zip
None of these worked.
Instead I bricked my tablet and flashed "P1_20100909.pit" and "GT-P1000_P1000XXJK1.rar" (from samfirmware.com) to make it work again.

Very easy, thanks for the idea! I copied the files to my external SDcard just in case though... Maybe it would be nice for you to remind people of that. Cheers!

It does work on the U.S. TMobile tab, I tried it. to me it boots faster, but seems to shut down slower.
Thanks! I follow your instruction but instead of deleting, I just rename them with .old extension (maybe one day will need them.. who knows.. )
Now it boot much faster!!
Hi,
is there any way to replace the boot logo?

As I pointed out in the first post the boot logo is located in the secondary bootloader partition which an ARM binary. The logo is not accessible via the file system. You would have to dump this binary, modify it and flash it again (e.g. with Odin).
The risk is that if something goes wrong (corrupted binary, signature check failed etc.) your device will not boot anymore. Not even into the flashing mode because it is also part of the secondary bootloader.
Such perma brick can maybe reverted with professional tools like JTAG if you are willing to disassemble your device.
http://www.ifixit.com/Teardown/Samsung-Galaxy-Tab-Teardown/4103/1
Noone so far seemed to replace the boot logo successfully.
One way could be to overwrite the original jpeg (see first post) with a black jpeg of exactly the same size (=20701 bytes). If there's no signature check and the jpeg format is valid this should work.

Thanks for the answer!
I searched the net also about these mysterious qmg Files, i do not understand why is Samsung using that kind of files, it just makes us unhappy not to customize the tabs
thanks worked very well, however, I have the t-mobile tab and the t-mobile splash screen stills shows up on boot is there any way to get rid of that one or is it similar to the samsung one that your having trouble removing?
Just flash an unbranded firmware, they will be gone then

Actually it works to overwrite the boot logo in sbl.bin with a custom jpeg file. The size must be less or equal 20701 bytes. I filled the remaining bytes of the original jpeg data with 0x00 but be careful NOT to overwrite the bytecode after the jpeg!!
When booting the device I can see the custom logo for 2-3 seconds.
After that, however, the Samsung boot logo shows up again!
Must be located in another place as well.
This sounds great! Could you make a quick tut how to do that exactly please?
Is there a virtual testlab for the tab or an emulator?

Hi all,
is it possibile to modify the content of the files fills with the content of the partitions read from the Tegra of my LG P990 with nvflash?
I had read the partition from the board with
Code:
nvflash -r --read <-partitionID-> my_partition.img
Unix's command file said to me that the output file is data:
Code:
$ file my_partition.img
my_partition.img: data
But if the correct img file is provided to 'file', for example the file that nvflash returned when we asked it to read the partition 23, the APP partition, 'file' said:
Code:
23_APP.img: Linux rev 1.0 ext4 filesystem data, UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (needs journal recovery) (extents) (large files)
How i can mount this type of image file ?
Easily with the 'mount' Linux utility
Code:
mount ./my_partition.img ./tmp_directory
Now, if I add the su binary of chains_dd compiled for my platform in the system partition image file and after,
reflash the image file on my O2X I should able to get root, right?
It seems too easy...
Any help is appreciated.
Thanks!
Yes, it is "easy" like that. I made similar staff (extract partition image from official update, mount, extract selected files).
Edit: Only I remember that I need to specify mount parameters related to partition format and mounting access.
Have you really gain root access only by copyng (and launching ) su binary in xbin directory?

Hey guys Lets get the ball rolling and get some development out into the light.
First you will have to download the OTA from Google.
Google’s OTA(13300): http://cache.pack.google.com/edgedl....1f63ef63d1f43c6222116806e5bea38a47e9f124.zip
Next download “SquashFS Exracter”, this tool is used to extract the System.img.
SquashFS Exracter: https://mega.co.nz/#!oEMFQCrC!JbD_9XeS28xu7vZBDipBzDWqdnF1i9cKMRzq2i_vEDU
When you are ready to go, simply drag system.img onto unsquashfs.exe, and the extraction will do its thing.
A new folder named “squashfs-root” will be where the system.img were located. This folder contains the extracted System.
Have a look around, and please report findings! :fingers-crossed:
Findings
/res/ - Contains some of the images used for the system. The boot animation is placed here.
/netflix/ - Self-explanatory. The Netflix app for the Chromecast.
/chrome/content_shell.pak – Contains a lot of useful information for the right eyes.
/chrome/osd_images/**** - Contains images used for the on-screen-display atm. volume slider.
/chrome/locals/ - Contains language files for the Chromecast.
Thx to ddggttff3 and tchebb for the links etc. :good:
Just FYI guys, here is link for newest OTA, build 19084, so you can check, what's new is inside.

I've been playing with unsquash in linux to add stuff to /etc. I realised linux can have a symlinks to a symlincs. So we can rederect /system/etc to /data/etc if we want to. It's probebly not so secure to have several symlincs in a chain, but I wanted ta add stuff like motd and profile to etc without reflasing it evertime I make a change.
First on then Cromecast
-----------------------------
cp -pr /system/ /data
On Debian 7
---------------
su root
apt-get install squashfs-tools
mkdir flash
cd flash
wget http://pdl.team-eureka.com/ota/19084.001.zip
unzip 19084.00.1.zip
unsquashfs system.img
cd squashfs-root
mv etc etc.bk
ln /data/system/etc -s etc
cd ..
rm system.img
mksquashfs squashfs-root system.img
rm -r squashfs-root
zip test1.zip *
And then you flash it with flashcast. Now we got a writable etc catalog. I haven't tryed symlinkc all catalogs in the system dir, but bin and etc are working fine as symlincs to /data/system dir.
Just FYI guys, there is again new build, and here is link for that OTA, build 46278.

Were you modifying the image as root? If not, you can have permission issues when rebuilding the squashfs file.

Alright.. I wanted the Note 8 version of gallery and i went into system/app folder and deleted the SecGallery2_Galaxy.apk but before deleting i saw that its size was 0.00 kb lol ..
But when i tried tried to copy and pasted in the extsd it pasted and showed 13mb..
Now i deleted the file and copied the Note 8 Galley and pasted in the system/app folder only to get an error " Operation failed " and i realized only 7 mb free space is there in the partition by going into the android emulator!
Now i also found out that, full size SecGallery2_Galaxy.apk was in the preload partition and i instead of replacing that i deleted the file in system/app..
Now how do i get back that file in system/app?.. is that what they call deodexed file?.. Please help..
Thanks a lot in advance
Just copy it from other rom, that You can explore with winrar.
Sent from galaxy n7105
The actual apk was in preload and was symlinked to system partition. Thats why it showed 0 KB in system.
You can get it back by typing in shell
Code:
$ su
# ln -s "Path of apk in preload" /system/app/
And this is not called deodexing.

Hi everyone, I modified the stock uRamDisk for CM11 by decompressing it, editing the fstab.encore.rc file, and switching up the part with sdcard0 and sdcard1.
P.S. I removed the zram (compressed RAM) option in the fstab because the Nook Color has a crappy enough CPU as is, so it wont help with zram. Use a swap partition on SDcard if needed.
P.S.2. This ramdisk is from the most recent nightly build (Jan 11, 2015). It may or may not work with older CM11 builds.
It's attached here. It wont let me upload the file as is, so I renamed it to uRamDisk.7z; rename it back to uRamDisk. After that, follow these steps:
0. MAKE A BACKUP OF THE /boot PARTITION IN YOUR RECOVERY JUST IN CASE. If anything happens, restore the /boot partition's backup.
1. Mount /boot partition at /root (it's an unused mountpoint in Android)
adb root && adb shell
# mount -t vfat /dev/block/mmcblk0p1 /root
2. Change directory to /root, rename the original ramdisk
# cd /root && mv uRamDisk uRamdisk.orig
3. Copy over the new ramdisk
adb push uRamDisk /root/
4. Reboot and profit
The internal sdcard will now be seen as external. You no longer need to have an SD card inside to have many apps like Kodi (XBMC), Firefox, etc, asking for external SD.
If it doesn't work for you for some reason, remount the /boot partition again, and copy over the original uRamDisk ( # cp -f uRamDisk.orig uRamDisk ).
I used parts of this script to figure out how to mod the ramdisk: https://gist.github.com/aperezdc/6533546

1. Do you have adb installed for Windows? If not, do that first.
2. I don't know how to make a flashable zip. Someone else might. Anyone wanna do that? I don't have time atm since college started. Sorry for the late reply.
3. The instructions are about as simple as they get. You should study the "mount," "cp," and "mv" commands. They are, respectively, for mounting partitions, copying files/folders, and moving/renaming files/folders.
4. You can't rename the file because by default, Windows doesn't show file types' endings (like .exe, .zip, .rar, etc). You need to enable that. Google it.
