... has a good description of the situation on the 5IT. Getting a flash_unlock binary should be fairly trivial, so perhaps we can tamper with the key store to add additional keys.

just a note of caution, if you write a bad key store or a bad bootloader, you will brick this device permanently. I would advice you to wait for the gen8 "SDE" release that will allow you to run your own kernel and userspace without risk of bricking. SDE should be out in a few days.

so with SDE we could run perm. root with the Archos' Froyo or even Googles Android 2.3 / 3.0 release and do whatever we want? (e.g. custom rootfs / custom kernel)
what are the borderlines of SDE?

Yep. Confirmed in another thread.

I really like the sound of the SDE. Can't wait to see it.

thats what I thought but is it dangerous to the root development to have a company rep seeing what we are doing? I dont know just wondering?

you really dont think that google/htc/microsoft etc dont use these forums? i know for a fact microsoft have been for many years when these guys were hacking up wm5 roms

its just a shame that they dont take positive actions from what they must learn (i'm positive that some people on here are much better devs than what some companies have in their dev teams!)

If I'm mistaken please let me know but the SDE looks like the environment that lets you install Angstrom linux. How will that be helpful in loading a rooted android image onto the device? Will it give us the ability to see the encryption on these flash chips so we can build new ROMs without fear of bricking? Just curious. Thanks!

there is some info for older devices at the bottom of this page:

Once the SDE firmware is installed on a device, this device will be watermarked and ARCHOS will be able to detect that this firmware has been installed once.
Installing the SDE firmware is considered by ARCHOS as a voiding of the warranty

Not really a surprise. Most of the stuff we do usually voids the warranty.
