As I understood (https://talk.maemo.org/showpost.php?...2&postcount=89), the flasher didn't succeed to connect to the device, so having a firmware to flash would not yet be enough.

I wonder how much of the flasher/bootloader is tied specifically to ARM ?

Here, we have an Intel x86 device, not an ARM based one like all previous Nokia (If I am not mistaken).
The flasher program is really low level - at least from what I remember when using it for Symbian, where we could flash a dead device through USB. That means, there is a bootloader of some sort in the device, separate form the OS. What I don't know is if this bootloader is part of the chip (like DfuSe in STM32 devices, which would then likely be different/incompatible when switching to x86), or if it is simply a part of firmware (like U-boot or Grub) which could then have been implemented in a compatible way in a x86 device ?

Is there any master who would knows more on this ?
