    I know it's almost completely useless information, but the Ovale version of the eVic has it's own MVR software and firmware. I own the Joyetech version. I was able to upgrade the firmware using either MVR software version, and either firmware version. The only change it made was the boot logo. At least we know the logo is in the firmware file, and not hard coded to the device. I know it's just eye candy, but I think it would be nice to make my own logo somewhere down the road.

    It looks like after MVR 1.2's release, the firmware will be packed with the MVR software in a single exe. Hopefully this won't complicate things too much.

    One of the owners of Ovale is Joyetech, so I can see why they have a branded firmware and pc software. The logo seems to be in the software since I am able to replace the Joyetech logo with the Ovale logo only by changing the firmware not the MVR software. Being that it is a low res image, it would fit on 64k firmware without a problem and still have plenty of room for the code.

    I am not sure if knowing their is an image would make hacking the firmware easier. I am still trying everything I can to decrypt and disassemble the firmware which would be the easiest way to hack it. But if the decryption is strong, then it will be almost impossible to decrypt.

    Other possibility is trying to hack it through the USB connection, trying to figure that out as well, if possible.

    Sniffing the USB connection may be our only option. I have had zero luck deobfuscating th file. Most deobfuscators and disassemblers won't even open it because it's a BIN file.

    I doubt the evic itself does decrypt it's own firmware file.
    Did you check this thread? http://www.e-cigarette-forum.com/for...are-image.html
    like minded people with some progress it seems.

    This guy claims to have flashed the firmware v2.0 using MVR v1.0
    Joyetech eVic Firmware 2.0 Quick Look

    Also, MVR can be tricked to decrypt the firmware file, which can be dumped from MVR process memory ofc, even without an eVic connected to the system

    This reviewer thinks that the pediodic pulse could be something used to detect the presence of an atomizer attached to the unit.

    I'm interested in this thread.

    One thing I can say is that the Evic itself seems 'Buggy'

    Last week I hooked up my Evic to the comp. and the MVR. The MVR said that on Dec. 28th 2012 there were 15 puffs taken on that day. But I know that this is impossible because during that time the Evic was in shipment from China and I recieved the kit on Jan 7th.

    But it could just be an error on my end...meaning that maybe the Evic was set to that day when I recieved it and I was trying it out before I went through and set the proper date and time. I'm pretty sure this is the case.

    Another thing is, I don't hook it up to the computer that often. Maybe once every two weeks. The last couple of times I hooked it up my comp. it doesn't recognize it. I says 'hardware not found'. So I go and reinstall the MVR and then it works. And it still has all my previous saved data from before. So it could just be my comp. and not the Evic. Anyways this is why I say it 'seems' buggy.
