DB2020 unlock (all threads merged here)

[onlyone]

I think db2020 unlocking is still suspended...

[giggs]

read somewhere cruiser can but not for free...gotta buy logs

[gruppuso]

where do you read it?
do you know how much is it?

[invNT]

It sounds stupid, but who knows...

How long the unlock code (NCK?) is?
Is the algorithm to check the code validity known / extractable
from the firmware available?

By other words, is bruteforcing the unlock code out of box (on PC) possible?

Cruiser isn't unlocking DB2020 phones ... now or before.

No ... acording to DaVinci team, they are using a 6 Tflops cluster which isn't your average PC (even if is high end), a Tflop capable setup is actually a supercomputer like the ones used by NASA ...

It won't bother me if i have to wait 5 days to decript the log un my 3.2GHz o/c-ed C2D CPU. But who will give me the app.

I suspect that they attack the loader rather than NCK.
If NSK is 16 decimal digits long we need 10GMIPS*(instruction_per_checking_the_NCK) to break it in 10 days.
It can be realized e.g. with PLD hardware or distributed attack with
help of the Internet community. So, the vital question is if the NCK checking code exposed in the firmware.

Over new CIDs brute forcing isn't possible, maybe Iam wrong but looks like after each wrong try the phone get disconnected and after the third is locked.

I am strained, when one can make something also with hardware with this DB2020.

But I think, that we must wait there still a bit.

Hi

Does any knows a free tool to unlock W850i mobile looked by "3 Mobile"
