mount

The code lists a bunch of mounted things, among which:

/dev/mmcblk0p1 on /home/user/MyDocs

Unmount the partition

Code:

umount /dev/mmcblk0p1 #OrYourPartitonHere

With "#OrYourPartitonHere" is replaced by "/home/user/MyDocs"

Return:

"umount: cannot umount /dev/mmcblk0p1: invalid argument" without the quotes

Despite not being able to umount the partition, I proceed with this:

Check the file system

Code:

fsck -af /dev/mmcblk0p1

The "fsck" indentified some problems, did some autocorrection. The problems turn out to be because I play some games stored on the external memory card with DrNokSnes or iNES and stop in the middle when the phone froze.

Then, if everything goes well, mount it back to its place

Code:

mount /home/user/MyDocs -o rw

Everything goes back to normal. THANK YOU. YOU SAVE ME alot of time and troubles.

I will copy all games to the internal eMMC to play to avoid this error.

Should I convert all the /MyDocs partition to ext3 instead of Vfat to completely prevent this stupid read-only problems? I have a 16GB external memory card, which I think is enough to communicate with the Windows PC.

It's not reinstalling the kernel it's "changing the kernel" ;)

Here's it how it works...

First of all you need two firmware images PR1.2 and PR1.3 for example

Code:

• PR1.3 = RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM



• PR1.2 = RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM

PR1.1.1 will work also... ;)

Then you need a matching emmc image (PR1.3_original or a custom image file for bigger apps partition)

Code:

• PR1.3 RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin 



• 5GB Apps 24GB MyDocs:

• 8GB Apps 21GB MyDocs:

http://www.mediafire.com/?5o1hkuuwhn8hh1c

1. Flash PR1.3

Code:

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

2. Flash only Kernel of PR1.2

Code:

flasher-3.5 -F RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM.bin --flash-only=kernel -f

3. Flash your EMMC (custom or PR1.3)

Code:

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

4. Reflash PR1.3 firmware (see 1.) or try --flash-only=kernel but with the PR1.3 image (see 2.)

:cheers:

Re: Cannot Flash EMMC

okay, i was once having a challenge flashing n900 emmc but yesterday, i surprisingly made it using windows 7 with windows xp virtual machine. and after flashing, installing/restoring apps, nitdroid, and CSSU etc, i noticed that my n900 seems faster than before. that was my first time of flashing the eMMC and wondering if i did something wrong before i flash that I feel some pain using my n900. the device is not yet OC'd but it feels like its on 850mhz.

Re: Cannot Flash EMMC

Ive been at this for a few hours now. It will simply NOT install eMMC. I have tried flashing different vanilla.bin 's and relevant eMMC's after. When it does boot the Mydocs etc is not visible when I run 'mount' in Xterm. I've even tried rescue kernel and initrd rpm from my ubuntu laptop and was unable to even see the disk in Gparted. Is the memory gone? arent the rootfs and mydocs just partitions on the same flash storage not seperate? it should be possible to just wipe the lot and start over like any other flash disk shouldnt it? I want to cry lol. I love my n900.

:EDIT

As a last resort after one more try changing the kernal as suggested by J4ZZ i will try to use my 8gb memory stick as the home/mydocs and see how it goes from there

Can you give a more detailed description of "corrupt"? There are a lot of helpful people here but we would need to have some idea of what proplems you are facing :)

Also, what device are you using?
