Hi,
My n900 doesn't seem to like rescueOS.
Thru ubuntu, i load rescueOS with flasher and after i type:
/rescueOS/mass-storage-enable.sh
It says:
[ 02950.651885] g_file_Storage gadget: No serial-number string provided!
[ 02950.662231] g_file_storage gadget-lun0: unable to open backing file: /dev/mmcblk1p2
modprobe: 'kernel/drivers/usb/gadget/g_file_storage_.ko' : unknown symbol in module or invalid parameter
If i type at flasher:
flasher-3.5 -k zImage -n rescueOS-initrd-0.5.3.img -l -b"rootdelay root=/dev/ram0 autostart=/rescueOS/usbnetworking-enable.sh"
My phone doesn't boot.
If instaed of zImage i replace with 2.6.37 then it boots fine.
I enter telnetd at phone.
Then in linux-pc it displays on top right [Wired Connection disconnected]
on xterm if i try to telnet at 192.168.2.15
after a long w8 it fails.
I can not even find MyDocs folder (with my things inside).
What am i doing wrong?

Did you mess with EMMC partitions?

flasher-3.5 -k zImage -n rescueOS-initrd-0.5.3.img -l -b"rootdelay root=/dev/ram0 autostart=/rescueOS/usbnetworking-enable.sh"

Correct, if there is no kernel with "zImage" in the directory, it of course doesn't work...

Then in linux-pc it displays on top right [Wired Connection disconnected]
on xterm if i try to telnet at 192.168.2.15
after a long w8 it fails.
Not sure what the problem here is. A wild guess: It could be the network manager...

Assuming the name of the interface is usb0, you might want to give the following a try
ifconfig usb0 down
ifconfig usb0 up 192.168.2.14
ifconfig usb0 netmask 255.255.255.0
ifconfig usb0 broadcast 192.168.2.255
route add 192.168.2.15 usb0
I can not even find MyDocs folder (with my things inside).
Because it isn't mounted.

Also note that rescueOS, unfortunately, requires at least a little basic knowledge of the linux command line.

1.I want to copy some files from my nokia n900 (MyDocs) to my micro sd card.
Flashing rootfs only doesn't kill the files on MyDocs (and also not your contacts as the wiki page says). Guess reflashing would be much easier for you...

For zImage i unpacked (the kernel) from latest firmware.bin and i placed the zImage there.

After typing the above, the msg appears on the upper right saying "Wired Network: Disconnected."
On the network manager there is a "Wired network (nokia N900)" in grey collor.

If i do them really fast i can connect
I managed to connect once. it Said on phone
login [1020]: root login on "pts/0"
the pts folder is on /dev/pts
On /dev/ are listed
mmcblk0
mmcblk0p1
mmcblk0p2
mmcblk0p3
I can only mount the mmcblk0p2, the others just gices input/output error.
So i mounted using mount - n /dev/mmcblk0p2 /dev/pts/
And after getting on /dev/pts/user/MyDocs/
There were only 1 folder and one file
the file was debian-m5-v3e.img.ext2
and the folder DCIM
anyway the file existed on MyDocs and it is the actual reason of disaster.

The problem came when i installed debian, after using the below command to expand the image size:
dd if=/dev/zero bs=1M count=1048576 >> /path/to/image.ext3

Is there a possibility that this command messed my files?


Also when i type
flasher-3.5 -k 2.6.37 -n initrd.img -l -b"rootdelay root=/dev/ram0
i usually get below a
>
How can i avoid this?

Eh, what? Who told you to do that? Use only the 2.6.37, nothing else.

It was /home/ that you mounted, not MyDocs. MyDocs is in an extra partition (p1), which you didn't mount. So you currently have that easy debian image on the 2G home partition as far as I can understand that.

And from the rest of your post, well, my recommendation stays:
Guess reflashing would be much easier for you...


And it overall looks like you messed up your maemo installation by executing commands you don't understand, which you shouldn't do. So you learned it the hard way I guess...

How can i avoid this?
mount - n /dev/mmcblk0p2 /dev/pts/
You lack basic Linux knowledge(no offense), I don't want to teach you the basics, as rescueOS assumes you are familiar with them. If you are not, you simply shouldn't use it IMO. I admit, it is not the most user friendly piece of software, but that's how it is. Nobody can be blamed for that and unless some volunteer appears to make some things easier, it will stay this way.

From what I can tell, you copied some (easy) debian image to /home/user/MyDocs/, but the MyDocs pratition wasn't mounted (which means your N900 was most likely already messed up prior to that anyway). So it wasn't p1, but p2 you wrote that image to, which MAYBE filled up p2(=/home), which might be the reason it doesn't boot, but it is only a guess...


But I think this is what you wanna read now.

I have a n900 which doesn't boot and needs to be flashed. I tried booting rescueOS to recover my data but failed.

Code:
flasher-3.5 -k 2.6.37 -n initrd.img -l -b"rootdelay root=/dev/ram0"
flasher v2.5.2 (Oct 21 2009)

Suitable USB device not found, waiting.
It gets stuck there, not able to find my n900. Even when I do a lsusb, I am not able to see n900 in the listing.

Can you please help? Any kind of help will be appreciated.

Could you please add a description how to add RescueOS as entry in multiboot?
Please leave the note in the documentation.txt.

Yeah I know I should be able to figure myself after a bit of googling but it would be always nice to have it documented.
I wanted your stuff as recovery console which would be preinstalled so I wouldn't need to bother with flasher if I need some simple recovery task
I would love this as alternative to backupmenu with full-grown rescue console (which backupmenu doesn't seem to have).

Did you run the flasher as root?

Nah sorry... I don't use it and I have 0 need for it, therefore I am not going to install and figure out how to do that. According to my memory (which may be wrong) it depends on bootmenu. If this is the case, then it has the same problems as backupmenu(death on messed up /sbin/preinit, libc, etc.).

Then you can figure it out and also document it :-).

@elyout: yw :-)

Anyway, I have just uploaded version 0.5.4, which adds absolutely nothing special but only increases useability a bit.

-Midnight commander has been removed because it eated too much space and wasn't really useful. I doubt someone was using it...
-After bootup it asks the user now whether he/she wants to have an ftp server activated with anonymous up/downloads everywhere, which shouldn't be a security risk because most likely you have it connected over usb networking to your machine... But this makes file transfer much more convenient as you can download files from your browser simply by visiting ftp://192.168.2.15/ or something.
It also asks whether you want to have telnetd activated and finally, whether usb networking should be set up.
Basically something that always should have been there.

Download (Use at your own risk as always . After all, it's still testing... )

Contributionts are still welcome. Keymaps for example because the default one isn't that optimal for most N900 with non-english keyboards.
