I was searching the internet for ways on how to retrieve logo.bin for our device. I've tried using the adb shell to retrieve the logo.bin but there seems to be no "logo" file exisiting on /dev/. I've also tried "Readback" from SPFT but it says that the Start address and length are not aligned. Is there any other way for me to retrieve the logo.bin from my device? I'm just a newbie :D TIA
