Hopefully I can find someone who can help me with this.
I have become fascinated with electronic cigarettes and one of the more popular regulated chips for sale tout's its ability to change logos.
The chip is the YiHi E-Cigcar. The firmware for the chip can be found http://www.yihiecigar.com/download_info/Upgrade-Software-for-SX350-50w-ONLY_OldBoot_YH_Logo_60W_20140813-Screen-flip_V2-4-d59228.html
I've downloaded a YouTube publisher's software the "changes" the logo, however, after decompiling his .NET application, I'm not convinced this wouldn't brick my chip. https://www.youtube.com/watch?v=kTy0AKTYzrg
I've written an application that reads the entire string in as hex, and converts to binary (assuming the firmware was unencrypted, and I could find an index of part of the image I'm looking for), but no luck.
I'm not convinced that this firmware isn't packed in some way, but I haven't the slightest idea on how to go about finding it.
If anyone could give some advice or has any idea on how to unpack / search for the logo's another way this would be fantastic.
Not that this is a need, it keeps me up at night because, I'm just one of those people who can't leave a problem unsolved... probably like a lot of you reading this.
Anyone who's up for the challenge it would be much appreciated.
