This is were you format /dev/mmcblk0p1 , because of the missing file system the memory card is noticed as corrupted.
First you have to install rootsh again. Then

Code:

sudo gainroot

mkfs.vfat -F32 -s64 -n MyDocs /dev/mmcblk0p1

mount /dev/mmcblk0p1 /home/user/MyDocs

ohk I just set up the extras repository now.its getting updated..once I install rootish..I gotta put in these command..but its not clear I mean..lyk from "mkfs till MyDocs" is one whole command??
sry..

If I only saw that post I should have suggested to add a line in /usr/lib/genfstab.awk

and /etc/rc.d/rcS-late to add 2 lines

Oh well reflash did great anyways... But what's with the memory card corrupt? is it MyDocs? can you access the MyDocs partition now? or is it your external memory card?

Nah mate..I dnt have an microsd..its the internal memory thats corrupt..but the apps memory seems normal..lyk 1.76gb..I think I mentioned in the previous post..that sounds normal..

Re: How to restore partitioned n900 emmc??!!

These are two commands separated by <ENTER>
If MyDocs will get formatted fine, then df will show the amount of free space like it was setup by Nokia.

Re: How to restore partitioned n900 emmc??!!

Hmmm... That's odd... What did you flash anyways? Is it the combined bin file or the EMMC bin file? If it's the EMMC then you should have no issues with the MyDocs as it will be reflashed/reformatted automatically by the flasher. Well who knows.. Maybe that's why they always suggest to flash both fiasco and emmc?

Re: How to restore partitioned n900 emmc??!!

:D now recommend nokia to hire michaaa62 instead of those current tech's who messed up your system. Well whatever their reason was they should have explained to you why did they do that to your device and for what.

I noticed that the wiki and your post here recommend not going over about 9GB. However, just for fun, I tried editing the eMMC beyond this recommendation and tried reflashing.

First I tested the waters with 10GB (10240) and it works.
Note: that there is a 30-60 sec delay during intiial eMMC flashing, I've noticed a bigger opt partition takes a bit longer so don't assume it's locked up, it does resume after a bit.

So after realising the 10GB was flashable, I increased it to 16GB (16384)

When I did this I moved the two characters after the 2048;
In hex editor 000000E0h looks like this:

Code:

The original 2GB eMMC will have:

000000E0 20 32 30 34 38 3B 0D 0A 09 09 66 73 5F 74 79 70

So for 16GB, I changed this to: 

000000E0 20 31 36 33 38 34 3B 0D 0A 09 66 73 5F 74 79 70

I'm currently using the 16GB partition.
