Hi,
I want to extract logo.bin from /dev folder in the android OS. I have come across posts that say that logo.bin is present in boot.img and can be extracted from it. I used dsixda to unpack boot.img but did not get logo.bin inside the dev folder. the dev folder is empty. I did it for two phone models but both were unsuccessful. Can someone help me on how to get logo.bin?

Regards,
Parag

1. Root device
2.
Code:
adb shell
dd if=/dev/logo of=/sdcard/logo.bin bs=3145728 count=1
3. Copy logo.bin from sdcard to your PC
The blocksize (bs) can be bigger or smaller depends of device size.

I have an unlocked and rooted Moto X running Kit Kat 4.4 and want to pull the logo.bin file but these commands return an error that no such file or directory exist.

Any ideas?

This is instruction for MTK, but your Moto X has a Qualcomm CPU. Anyway for QC device procedure is more complicated, IIRC you need to edit some partition on /dev/block
