Always with the same cable and with the same computer.

Cold flashing is implemented differentely and implication normal flashing working --> then cold will work too is not truth.

That is expected. Bootloader cannot be booted.

I'm just waiting for output from 0xFFFF when N900 is connected to usb 2.0 host (without hub, etc).

It gives nothing (full battery):

I waited 65 minutes in this state.

Re: Did I brick it? Flashed broken xloader.

Hm... this looks like broken/non-working usb :-(

You can try: remove battery, start 0xFFFF, connect usb cable, insert battery

Also can you try using another motherboard/computer for flashing?

Keep in mind there is only ~200ms period cold-flasing can be done, so it might take a couple of tries

But I should see something in kernel's log even flasher was too slow. I don't get single line.

I would say this is broken usb, but it happens when flashing modified xloader.

Re: Did I brick it? Flashed broken xloader.

Any news on this?
Cause it may stop people from trying to hack xloader.
Which i like to see cause gpio and spi on sdcard pins would be nice.
I have a n900 with missing (omap 1808 (ARM926EJ-S)).
it boots but the only booting option is debian900 which fails to bring up wifi and i have to repair the keyboard first to able to login.

But 0xFFFF doestnt see this device either, even it is booting fine..
usb networking seems to stop working.
Is usb dependend on broadband? (Maybe aapos fix hit broadbands firmware)
Is 0xfff distro dependend?
if there is interest i can solder a serial (+ levelshifter) to the debug serial pins on n900.
Not booting is fine but bricked is kind of hard.

Have you tried the things ITT? http://talk.maemo.org/showthread.php?t=94802

Not yet. I have discussed about opportunity to reflash with fbus/mbus, even I know nothing about them. I'm trying to revive this unit and proof it is fully working and no bad-usb. ...And then brick it again =)

At this moment I'm claiming messing with xloader will lead bricking.
(Maybe the point is formally valid xloader, but broken signing).

Meanwhile I have collected what we (=community) know about NOLO hacking.

I can do it, but i'm in Berlin/Germany

Or try to find xxxed Nokia Phoenix Service Software.
This has especially an option "Dead USB Flashing"

Hi,

I created a new topic, but apparently it didn't get published yet. I'm gonna copy-paste what I wanted to ask:

I recently acquired a N900. I tried to install Debian directly on the internal memory (I don't have an SD card) following this tutorial -> n900.elektranox.org/installation.html. But now, the phone no more boot up, nor appear via dmesg when connecting it via USB.
I've been reading that topic, and after trying many solutions on my computer, I think that's the best solution I have in order to revive my N900.
If there is someone like explit, who can help me by flashing it with F-Bus/Mbus Cable (Contacts under the battery) and UFS/HWK Flasher-Box, living in France, that would be awesome. If not, I could travel to Berlin to solve that issue.

I'd like to flash my N900 with F-Bus/Mbus Cable and UFS/HWK Flasher-Box. I created a topic speaking about my issue, and I'd like to know if it's possible to reach you at Berlin or if you know someone who can do the flashing in France. Thank you.
