Slightly unusual flashing problem
 
Attempting to flash the EMMC and firmware on my N900 - flasjing the EMMC seems to go okay
Raw data transfer EP found at EP2.
Image(s) flashed successfully in 25.843 s (9331 kB/s)!


but flashing the firmware just throws this up

Version 1.4.14.9+0m5
Image 'xloader', size 14848 bytes
Valid for RX-51: 2601, 2602, 2603, 2604, 2605, 2606
Version 1.4.14.9+0m5
Image 'secondary', size 109440 bytes
Valid for RX-51: 2601, 2602, 2603, 2604, 2605, 2606
Version 1.4.14.9+0m5
USB device found found at bus bus-0, device address \\.\libusb0-0001--0x0421-0x0
1c8.
Raw data transfer EP found at EP2.
Using flashing protocol Mk II.

C:\flasher>


There's a load more of the "image 'xloader'" stuff but there doesn;t seem to be anything informative there - the firmware flashing stage takes less than a second before dropping back to the prompt. Restart the N900 and it looks like this:

Anyone have any suggestions as to what I've done wrong and how to correct it?

Cheers

always(Strictly do this) flash maemo image first before EMMC never in your life flash emmc first before the combined binary file else it will result to that :p

Flashing the emmc will cause the device to hung up unless rebooted so flasher won't detect the device after a perfect emmc reflash... Maybe it's a flasher bug i dunno...

Er...

From http://wiki.maemo.org/Updating_the_tablet_firmware

"When flashing the eMMC content, the safe way is flash the eMMC/VANILLA image first, then remove battery for a moment, and then flash the FIASCO/Rootfs image. Do not boot up the device between the two i.e do NOT use the -R parameter at the end! Rationale: on accidental booting in between the 2 flash processes, the sequence formerly suggested (rootfs first) will result in a broken system. The sequence "eMMC first, then rootfs" is checked back with Nokia affiliates and is proven to work. The former advice on tablets-dev.nokia.com was not based on any facts for the recent eMMC VANILLA image. It's fixed now and in line with this wiki"

In other words, the Wiki was either FOS before or is now.

I take what it says with a grain of salt.

try installing backup-menu and uboot then try to restore rootfs but use the normal flasher image
ps it is just a wild guess

Then do not always trust wiki... Wiki may be outdated or modify by any users so it is always a good etiquette to ask us first for a more detailed and accurate answer. Seriously no need to bother removing the battery between flashing those two. just do

flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f

Then

flasher-3.5 -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

and all should go on smoothly

The actual order isn't all that important, what's important is that you never ever reboot the phone in between.

The details:

Any rootfs (COMBINED_MR0) image will, on the first boot, move a bunch of stuff from rootfs to emmc to free space.
If EMMC if then flashed, that data is erased. Like themes, fonts, images, and so on...

Thanks everyone for your advice - reversed the sequence and all went well. Who would have thought that there was misinformation on teh internet. Older, wiser, sadder.

This is totally wrong sorry... If you reflash emmc the device would get out of flash mode automatically even without the "-R" parameter which would only mean you won't have any chance to reflash the combined bin correctly anymore which would result to the problem by the OP.
