I'm in the same boat as you and no one seems to know how to do it.

Is it possible to get a cloned OS2008 and copy it to the 2GB internal flash and boot up from there?

Is there a difference in the CA-101 cable and other micro-usb cable?

Please help!

I dont have N810. On the N800, there is two modes one can upgrade, one use the default dl from website, two ask for the location of the file. Does the N810 has mode 2, ask for the location of the file? If so, just point to he location of your upgrade file somewhere in the SD card, would that solve the problem? I am sorry if N810 is completely different, as I said, I ain got one, ........, yet.

Why don't you purchase another USB Cable with the correct mini or micro USB connector. (Dependent on device you own)

Have you really thought through your question. How would a device remain connected wirelessy whilst updating the firmware which in turn holds the method to connect the device wirelessly to the PC.

---edit--- (Oh unless you were thinking to copy something wirelessly to device whilst existing OS is installed and then update it magically?? Cloned OS and load on the external memory, now that might be possible eventually, who knows)

With a wired connection (i.e. the USB) it is physically hardwired and connected to PC which is in turn feeding the firmware update when there is no firmware installed on the device.
(As currently intended by NIT development team)

Well at least that is my understanding in simple terms of what is going on.

These things are a dim a dozen and come bundled with most cameras/mp3 players/PDAs/etc. If one end plugs into your N800 and the other into your PC, you're good to go.

Bingo.

You can't use data (or code) off the rootfs to write onto the rootfs—it just doesn't work that way.

The OP has a N810 with a USB micro-B port. This is a fairly recent USB form factor (yet another!) and is not that common or easy to procure...

The question is not stupid per se. The Sharp Zaurus line are now ancient machines, and for all this time they have had an autonomous, link-free flashing procedure (although they do have USB). You just copy three files (a boot image, the firmware image and the flasher) to a SD or CF card by whatever mean is practical, put that card in the Zaurus, boot it with a special key combo (just like the tablets), and it flashes itself.

There is no reason the tablets could not work this way too. I guess Nokia went the USB way so they could provide a friendly Windows installer for non-geeks, but it does have drawbacks (like needing a PC handy, making the flasher OS-dependent and a variety of USB hassles).

In the early 770 days there was a project to create a flasher that would work on the tablet itself, but I don't know if it's still alive.

...but you can boot from the MMC/SD etc. and if you find the right files there you can flash the flash with that :-)

Yes, you can't. So the solution is to boot from mmc and then you can flash rootfs. You can also flash kernel and initfs so in fact it is possible to update everything except bootloader.

So the steps to do it are:

1. extract .bin image via linux flasher, copy zImage, initfs.jffs2, rootfs.jffs2 to mmc
2. clone current system to mmc and boot it
3. flash rootfs, kernel and initfs from mmc to internal flash (preferably in that order and with no reboot in the middle). Without usb cable you have exactly 1 try for kernel/initfs pair :-)
