FAQ2:

|
This file tries to collect a bunch of common questions/answers about flashing
|
|
|
|
|
|
*) Why implement a free software flasher?
|
|
|
|
The Nokia Internet Tablets are based on Free Software (software libre), but
|
|
not everything included *is* free software, for instance, the firmware flasher
|
|
tool.
|
|
|
|
The 0xFFFF project aims to feed the minds of those who really want to
|
|
understand how these gadgets work internally, free the knowledge to
|
|
avoid the restrictions and fill the lack of information on the most
|
|
important part of the system.
|
|
|
|
That's it, now you can build and run this flasher on *BSD, w32, MacOSX on ARM,
|
|
powerpc, x86, mips, etc...
|
|
|
|
|
|
*) Can I brick my device?
|
|
|
|
Of course! You're free to do what you want with your device :)
|
|
|
|
Seriously. Flashing a device is not a safe thing, so I give no warranty
|
|
of what will happen to your device when using this tool.
|
|
|
|
BTW, after a huge number of tests I can say that these devices are hard
|
|
to brick, but if you are scared about bricking your device you should
|
|
use the flasher provided by Nokia, it's better for your heart's health.
|
|
|
|
|
|
*) What can I do with 0xFFFF?
|
|
|
|
Actually 0xFFFF allows you to:
|
|
|
|
- flash separated pieces of the firmware
|
|
- flash full FIASCO image
|
|
- load kernel & initfs without flashing
|
|
- cold-flash bricked device (without NOLO)
|
|
- retrieve information about the device
|
|
- reboot de mother board
|
|
- extract the current firmware pieces from the device (dump)
|
|
- set the USB host/slave mode
|
|
- set the R&R mode and flags
|
|
- pack/unpack FIASCO firmwares
|
|
- automatic piece identifier
|
|
|
|
|
|
*) What is NOLO?
|
|
|
|
NOLO is the 'server-side' part of the flasher from Nokia. NOLO means
|
|
NOkia LOader and it's composed by two pieces of the firmware that are
|
|
flashed together.
|
|
|
|
On the n800 firmwares, these two pieces are distributed in a single
|
|
file, but when flashing a 770, NOLO requires to provide the xloader
|
|
(without committing) and then the secondary piece.
|
|
|
|
This piece of software is closed source and is the responsible of
|
|
handling the requests from the client-side flasher. It provides a
|
|
query-like interface via usb control messages for doing different
|
|
actions on the device.
|
|
|
|
|
|
*) How can I identify my device?
|
|
|
|
Theoretically 770 and n800 have different USB device ID, but this is not
|
|
true at all. The first series of the n800 comes with the same usb-id
|
|
than 770. That's weird!
|
|
|
|
So, the only way to identify the device is by asking nolo for the version
|
|
information of different pieces of the firmware. This can be faked, because
|
|
you can flash 770 stuff on n800 and viceversa, but it's not recommended
|
|
because it wouldn't work :)
|
|
|
|
|
|
*) Can I unpack FIASCO blobs?
|
|
|
|
Yes, last version of 0xFFFF has full support of FIASCO images.
