    Wouldnt it have to open the bootloader and all that jazz in order to upgrade the kernel to the gingerbread one though? That would require the key to be sent along with the ota update.
    Ahh.. I see what you are saying, yes it would.. but rest assured that key is also encrypted/hidden somehow and also probably not easy to locate on the file. But you are correct... there has to exist something on that file to let it do what it does. I suppose that could be a course of action... I just don't see that being a way to get around the encryption scheme though. It's not like the gb image is gonna have a txt file on it called moto keys.. lol.. I wish though...

    Even if its encrypted its still there. Probably encrypted just as heavily but still, gives another shot at something to crack.

    If you're trying to crack the encryption, it won't matter.. either way you are doing hash collisions. Its math not roulette.

    true but its another thing to try lol. By the way, great find on that long post earlier about the SHA - 1 encryption being broken.

    I agree with the posts above. There is some sort of equation we have to find that Motorola uses for encryption. I wrote an encryption program last year and math is how it works.

    Im with the guys up top. I don't think this thing will be cracked by anyone. Its like looking for one grain of sand on every beach on the world. I just hope there is a leak when this thing hits eol.

    Well RSA is just linear algebra, as it SHA-*. It's just linear algebra on a vector quantity or matrix instead of a single number.

    I have been looking into hash collisions, but I'm not sure how viable it would be to pad our modded bootloader with 0x00's to actually collide.

    All I can say is that I hope this thing gets cracked and whoever does it or gets a hold of a leaked sbf that is unlocked will get a fat donation cause I just got this thing cause my wife is a tight a** and wouldn't let me get a tb.

    Well then I have a solid understanding of all of the components involved if that's really what it is... and I think I still have my Matlab textbook somewhere in my room in the rubble.. lol. The problem is I lack understanding on the android end.. like where are the input values coming from? Your understanding of linux vs mine is very different... you are on a whole other level than me. My understanding of the way the recovery works and all that is very limited.. But if I don't have to understand any of that ridiculousness, and I am just presented with input values and a really difficult math problem... I certainly could take a stab at it.. I also am presently at college so there are plenty of graduate students I could hit up if I were completely lost. I'm just not a legit programmer like you are.. I know a little.. enough to do the things I have tried to build.. but I followed what you have been doing and that stuff is completely foreign to me.

    I can offer my brain for math.... as for the rest.. I really am lost.

    I don't understand how the bootloader actually works... so the second part of your post is hard for me to understand.
