I took a look at both the flash drive dll and kernel with IDA Pro. I need to read more of the documentation before I can make good sense of them though. Under the functions tab on IDA Pro there are a host of things listed. As far as an ioctl related text string, in the kernel I found oalioctl.

Can the info from the kernel be used to modify either bksamsumg or bkondisk?

it isn't text strings we are after, it is hard assembly code. are you a programmer otherwise? then i think asm would not be too bad, i can give you some links. BTW i also want to look at this, as it sounds interesting, so we can work together.
oh and somewhere i have some documentation on nand dumping, trueffs, etc.

oalioctl is the stuff bk programs use (KernelIoControl, IOCTL_HAL_something)

you could do that to the bk programs yes, but only if your device's kernel has suitable ioctls for you.

Definitely not a programmer though I wouldn't mind learning C or something similar (social psych grad student, actually). And thanks for taking an interest in this project, I'll pay attention and be a quick study, so as not to waste your time, promise

Here's the flash drive dll, can I email you the compressed kernel? WinRAR got it from 544KB to 175KB with no difference between normal and best compression.

I didn't think of it earlier, but here's a rapid share url for the dump.bin and the extracted dll's and exe's.

I have a skype account. If that suits, I'll pass it on, if not I'll get one for msn.

Here's the link to rapidshare.de:

Did you get the msn info I sent?

Oh, and I found a site on reverse engineering, reverse-engineering.net, that looks more educational than the last one. I'm doing that one for homework in the interim.

Thanks again.

Is there a time on Sunday that works for you? I've learned some neat things about registers, opcodes, and flags from the reverse-engineering.net site but nothing that will help me determine if that kernel contains useful ioctl's! I have solved some fun reverseme's, though.

If not, enjoy your weekend!

I just took it for granted that you'd be offline by the time I got home from work at 6 pm during the weekdays, with the six hour difference and all. In fact, I'm astounded that you posted at 8 pm GMT-5!

Oh, sorry! I only use the msn on the laptop and I've been on the touch playing around with voip.

Sad to say they're easy reverseme's, one's that come with the answers in case you get stuck. There are some on the reverse-engineering.net site and some on tuts4you.com. This assembly stuff is totally new to me, but it's freaking awesome! Way better than sudoku.

that's neat especially the fact you find it more interesting than sudoku. the reverseme's, are they for the ARM processor? though, even if x86, it wont be too hard to learn arm afterwards.
anyway feel free to check msn anytime, there is a chance i'm there, i'm not living by the usual rules

p.s.: got your request now!
