Hello
I've got a problem with my N900 that whole memory became ReadOnly. I cannot delete any files,I cannot format the storage, fsck does not find any problems, and I cannot connect it to PC in MassStorageDevice.
I cannot flash emmc as well I am getting the following Error when trying to do so:
Raw data transfer EP found at EP2.
SU_GET_UPDATE_STATUS_REQ terminated with error code 1.

The Flashing is done under WinXP Pro.

Anyone knows how solve this issue?

ouch ! can't flash.. this hurts ! may I know how are you flashing in details ? you may be doing something wrong .

does maemo still boot ?

could the memory chip be corrupted?

well , since you didn't reply , I will assume maemo still boots
try unmounting the partition , then mounting it again with rw option
in x-terminal as root :
umount /home/user/MyDocs
mount /dev/mmcblk0p1 /home/user/MyDocs -o rw

and see if you can still copy anything into it , or if it can be exported for usb mass storage .

[Edit]

after some thought , the emmc is supposed to be flashed correctly no matter what condition the partitions are in ...

try to flash the fiasco image and then flash the emmc image , hope that works...

if you fail to fix the emmc by other means try the following :

first download ubuntu live cd image , burn it to a cd , insert it on your cd drive , and reboot your pc , ubuntu shall start without affecting your windows installation .

now follow instructions at :

http://wiki.maemo.org/Repartitioning...rom_a_linux_PC

these instructions were intended for those who want to custom partition the emmc , while you aren't interested in repartitioning , follow these instructions , and when you get the emmc as a device in /dev/sd* start gparted , choose the correct device , delete all partitions , make one big ext3 partition.

after that , unplug the n900 from pc , remove the battery , reconnect the usb cable , press U , and put the battery back in, flash the pr1.3 fiasco image and then flash the emmc image

see how it goes...

Thank you Ivyking,
First, the OS won't even boot, I had to flash fiasco image- worked fine, but then I noticed it is in read-only mode.
Trying to flash eMMC failed. OS still bootable and I was able to install rootsh. The Roofs is full 83% after reflashing.

I will try with livecd when I get home and report on my findings

PS: I can connect the N900 in Nokia PC suite mode and browse the contents, but again I cannot copy anything to N900

wait a second, what I understand from your description is that you started maemo in between flashing the fiasco image and the emmc image...

what you should do is turn of the n900 , slide open the keyboard , press and hold "u" ,plug the usb cable in your n900 and in your pc .

now in the command prompt..

change the current directory to where flasher-3.5 is then :

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

after that's done...

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

thats all...

No, I did not start the OS in between.
On first attempt, I just flashed the fiasco image. When I found out, that the internal memory was corrupted, I decided to flash eMMC as well and did exactly the same steps you proposed- after flashing fiasco (no reboot -R key used), I started eMMC flash (the N900 had dots running on the lcd which frozen after a couple of seconds). and I've got the following error:
Raw data transfer EP found at EP2.
SU_GET_UPDATE_STATUS_REQ terminated with error code 1

At this point, the only way to reboot the N900 is to take the battery out.

The phone goes to Nokia RMA.
After it is coming back, it will be ebayed.

Do not use any USB keyboard or mouse when you try to flash EMMC.

Thats my experience.

Someone could have made a lot of money with a

business. $50 to flash your N900.

No success, no pay.

It's probably too late now.
