By extracting attached flashable zip, you'll know how to change Galaxy Tab 3 8.0 boot logo.

WARNING: Don't use any image created or edited by Linux image editor (i.e. Gimp, Gwenview, Krita), you'll got a black screen of death! A simple, powerfull, nice, and free Paint.NET - but Windows - image editor worked!

A pdn file (Paint.NET multi layer image) attached here as a template for your convenience.

BACKUP: If something goes wrong, flash param-samsung-t311.tar.md5 using Odin as PDA or Heimdall v1.4.0: "sudo heimdall flash --PARAM param.bin".

Some technical explanations:
There is a script inside my CWM flashable zip. This script will flash a logo.jpg overwrite the original one. I called this in-place flashing because only logo.jpg is replaced, the other files in the param partition untouched. Attached boot logo CWM flashable zip should be compatible for all T31x family but I only test it on T311.
Code:
#!/sbin/busybox sh

# Galaxy Tab 3 8.0 boot logo changer script
# Ketut P. Kumajaya, Nov 2013

# Extract device param.bin
dd if=/dev/block/platform/dw_mmc/by-name/PARAM of=/tmp/param.bin bs=4096
mkdir /tmp/param
cd /tmp/param
tar xf /tmp/param.bin

# Replace logo.jpg, repack param.bin
cp -f /tmp/logo.jpg /tmp/param/logo.jpg
rm -f /tmp/param.bin
tar cf - `ls | sort -t.` > /tmp/param.bin
dd if=/tmp/param.bin of=/dev/block/platform/dw_mmc/by-name/PARAM bs=4096

cd /tmp
rm -rf /tmp/param
rm -f /tmp/param.bin
Yes, Galaxy Tab 3 8.0 param.bin is a plain tar file but you have to use a correct command to repack it.

Flash attached CWM flashable boot logo at your own risk! I only test it using PhilZ Touch recovery. Please reboot into recovery before performing a normal reboot!

[QUOTE=ketut.kumajaya;47507264]By extracting attached flashable zip (I'll upload it later, depend on user interest and response to this thread), you'll know how to change Galaxy Tab 3 8.0 boot logo.

I am wondering. Put please, will try T310. And param.bin probably better to use each from its firmware versions.

So, backup your original T310 param.bin:
Code:
dd if=/dev/block/platform/dw_mmc/by-name/PARAM of=/sdcard/param.bin bs=4096
Then upload the zipped version here, I will create Odin flashable tar.md5 for T310.

I will explain in OP, my logo changer CWM flashable zip compatible for all T31x device.

I will create a tar.md5 param.bin for you but I almost sure the attached tar.md5 file in OP also compatible for T310. Feel free to create your own boot logo and share it in "Themes and Apps" section. Don't forget to add link to this thread and credit for me

Thank you!

I confirm T311 param.bin compatible to T310!

Fabric texture on Android boot logo looks good on device. So, which of your choice?

Based on Google search, I am still the king of Samsung boot logo modder. This mod is dangerous! Be careful if you try to adapt this work to a different device. Upload your device param partition raw image somewhere, I will help you to analyze the contents and give you some advice if possible.
