root

I NEED ROOT! badlyyyyy

Help me understand more about Android.

Gingerbreak we know does not work. is this because it is NAND locked? and NAND can only be unlocked if it has "open" recovery? is this correct?

Is the gingerbreak exploit code patched? or does it not work, because say, the folder locations and other things are just different?
-If this is true. That would suggest./ Which some tests grounds. Code could be written specific for the D3.

What options are available?

Not that many options, here. I tried Gingerbreak, as well. The only other root is an update.zip exploit, but that won't work as they still sign their updates. Or using the low-level TCC USB mode, but since they package their updates with an MSI I haven't found a way to inject root into that.

I would go on the assumption that the GB ROM will not have root, for the long term. Cowon has done things in a way that they have not made it easy.

what is MSI?

Possible to recreate their signature if RE'd?

but why did gingerbreak not work? because they have "patched" it, or just because sometimes , some devices it doesnt work. but the exploit is somewhere there. Which means, if the code was modified, for this D3 . We could root it?

[roebeet]

Sorry, I meant EXE, not MSI. In other words, their installation process is packaged and I haven't been able to reverse engineer it. As a comparison, my SmartQ R10 (another Telechips device) has its TCC-based installation process broken out so that you could actually inject root into a .tgz file and then use that as a replacement for the stock firmware. But that won't work in this case because there is no .tgz file to hack, it's probably all in the EXE.

As for Gingerbreak, it's probably the latter. Not all devices are known to work with it - could have something to do with the partitioning of the device, for example.

so. with the gingerbreak cpp. how is it run on android, what is it compiled to?

android is linux, I know nothing of linux :( and not much at all about android thus far.

No clue on the internals (I'm not a dev) - but I know it requires a formatted microSD and it uses vold - that's the binary that mounts the microSD. Android is actually not Linux - it has a Linux-based kernel, but the OS itself is different.
