Boot Logo Changer
Change the boot image (NOT the bootanimation) that shows BEFORE the boot animation.
This has only been tested on the T285, but should work on the T280.
If in doubt, check to see if your PARAM partition is mmcblk0p16.
There are programs on the Play Store that can show the partitions, there names and other info.
This app does make a backup of the original PARAM partition and stores it on your /sdcard as PARAM.bak.
MAKE SURE YOUR SDCARD IS MOUNTED WHEN YOU GET INTO TWRP or CWM.
(Have NOT tested in CWM as I have TWRP installed).
Many thanks to [email protected] for the original script for the Samsung Galaxy Tab 3 8.0.
He has kindly allowed me to modify his script for the Tab A (SM-T285).
His xda page is: Samsung Galaxy Tab 3 8.0 Boot Logo
To change the logo (.jpg file), replace the logo.jpg in the tmp folder with your own .jpg file.
Remember the Galaxy TAB A (SM-T285) display is 720x1280.
Steps to install:
- Reboot into recovery
- Select Install from recovery menu
- Select TAB-A-T285-LogoChanger.zip
- Follow recovery install prompts
- Reboot and enjoy!
If you need a restore script, please contact me or post a message.

device soft bricked but can enter download mode (Vol Up + PWR + Home). I did a:
# dd if=/dev/mmcblk0p16 of=/storage/emulated/0/param.lfs
before flashing the custom param. I restored the device using heimdall (GNU/Linux PC)
$ sudo heimdall flash --PARAM param.lfs
device rebooted and worked

Should have no problems with the .zip file. I used on my T285.
It will make a backup of the PARAM block and store it on you internal sdcard before changing the bootlogo.
All that had to be done was replace the logo.jpg file in the zip file (drag and drop). Install it in TWRP.
Obviously, if the logo.jpg file you put into the .zip file is very large, you may end up overwriting something.

the logo.jpg I used is about 600KB in size it may be the problem. What must be the right size so I do not overwrite anything?
I have dumped the partition /dev/block/mmcblk0p16 to a param.lfs
then the param.lfs appears to be a POSIX TAR Archive (GNU) can we just repack the file and modify only the logo.jpg? (the recovery script will repack the tar archive)
after modifying can we just write it with dd?
# dd if=./paramodified.tar of=/dev/block/mmcblk0p16

The original logo.jpg is under 100kb, so a 600kb file would be too big.
I would keep the file under 150kb just to be safe.
Yes, you can use dd to write the modified param file...that is what the logo changer script does.

The script works now, I've reduced the jpeg to 50KB but it is blurry. Thank You
I have uploaded my param.lfs (it is compressed with 7z to reduce size from 2MB to 420KB, 26193062 is a CRC32 hash checksum of the file to verify that it is not corrupt) from mmcblk0p16 that can be flashed with heimdall ($ sudo heimdall flash --PARAM param_26193062.lfs) if someone else messes up.
1. download param_26193062.lfs
2. decompress with 7z (7z x param_26193062.lfs.7z)
3. flash with device ($ sudo heimdall flash --PARAM param_26193062.lfs)

I no longer have a T285. All my T285 files are deleted.
But, my guess is you made the .jpg logo too big.

Any one have stock param.tar file for flashing on sm-t285?? Plz help me? ? ?

You need yo rename your image to: logo.jpg
Then use 7zip or winrar to open bootlogochanger. replace the logo.jpg in the zip file with your logo.jpg
Hey, today in this post I've discussed on the topic
"How to unpack/repack img without PC or android tools (android tool is a little complicated and sometimes doesn't works)."
So let's get started
First of all download & install 'android image studio'
1: open it and click on repack/unpack
2: select the port ROMs boot or recovery img.
3: we get two folders
a.) Split_img --->> contains kernal zimage.
b.) Ramdisk----> contains init.rc recovery. Fstab etc..
4: to delete any file long press on it and click delete
5: to import any file click on import button in right panel & select the file
6: after making desired changes. Repack the img using repack button
7: a file will be created with the name image-new.img
8: export this file using export button and select the desired location.
Congratulations you have just ported an img without PC easily.

I need more help, trying to open a .IMG boot file for Samsung s5, it gives the "No Image Supplied" error
Screenshot
Using AIS. Trying to port custom recovery but first thing I've tried is to just unpack and repack stock recovery. When repacking output of AIS is new IMG and new ramdisk. New IMG is smaller than original but from what I've read this should be okay. Flashed new IMG and attempted reboot recovery and all I got was black screen. Flashed stock recovery and it booted recovery fine. Not sure what I'm doing wrong. I used AIS to open the new image it created and then kept doing file/folder comparisons on the output. I narrowed down the difference being recovery.img-ramdisk.cpio. But when I unpack with cpio the contents of the archive are the same. Additionally, I repacked the contents with cpio but it still comes up as not matching the original recovery.img-ramdisk.cpio. My device can and does make replacement recovery images using applypatch with bonus files and boot img. Any help greatly appreciated!
