This is already tested from PR1.0 to PR1.3 100% safe if done correctly
Ok here's a screenshot of my modified EMMC image file

As you can see in the screenshot value is '5120' it means I've set EMMC/Internal flash to 5GB from 2GB. And the little circle below is the swap partition set to '896mb'
Here's a good partition table
1 gigabyte = 1024 megabytes
2 gigabytes = 2048 megabytes
3 gigabytes = 3072 megabytes
4 gigabytes = 4096 megabytes
5 gigabytes = 5120 megabytes
And so on... just do the maths...

Take note of the whitespace/Space from the = sign

Yay! And that's all?? Soooo easy! i'll give this a try!! thanks for tuto and screenshots!

edit: when editing the EXT3/emmc value, is the MyDocs space automatically resized? I mean, I don't have to modify another value??

Re-Edit: What Hex Editor are you using?? I'm using Hex editor Neo and i see weird characters. I can't find any value!
(Ooops! Sorry! I wanted to edit the firmware!)

yep mydocs automatically resizes since it just takes up the available space left.
I'm using windows 7 so I used this one.

could you post a screenshot of the hex editor your using with the emmc image opened? I think all editors should work and have the same output.

what if i wanted to create several partitions?like

mmcblk0p1 - 7gb
mmcblk0p2 - 5gb
mmcblk0p3 - 5gb
mmcblk0p4 - 5gb
mmcblk0p5 - 5gb

can i use the hex editor as well?or am i better off with GParted?

This is just for specifying the storage space for installable applications not for the whole internal flash.. So this is not for making multi partitions. In addition you could repartition mydocs like mine I used partition magic
So in short yep use gparted for multi paritioning.

Here is my screenshot!



As you can see, I gave 4GB for Applications and 896Mb (Like Radicalz38). Now time to flash, i will do it later in the afternoon!

Ps: I'm using Windows XP!! and Hex Editor Neo!

You can also go higher with swap by the same method, i.e. either replacing the first space or the leading tab on the next line - so 256;<tab><tab> becomes 1536;<tab> (for example). I did this with mine and also upped the apps partition to 10752, both worked perfectly. The tabs are the 09 (hex) values that you can see in the screenshots posted above, but I'm sure you all knew that already, right? ;-)

Incidentally, this used with Robbie's excellent BackupMenu program means you don't even have to reinstall anything - simply use it to backup rootfs and optfs, copy the generated tar files plus MyDocs onto your PC (via USB is best, but SSH/ftp works too), flash the edited eMMC image then use BackupMenu again to extract the tars into the new, larger spaces and finally copy MyDocs back (again, by USB, SSH, ftp etc). Obviously, you won't be able to copy all of MyDocs if it exceeds what is now available on the FAT partition. I know this works as it's what I did myself

I have successfully flashed the N900. with the Modified emmc image i finally have 25.10GB for MyDocs, 4GB for applications and eventually 896MB of virtual memory! I will install conky later and post a screenshot! I don't notice any problem, for the moment of course!
Thanks to Radicalz38 for this Tip!!!

i have succesfully flashed my N900 too!! lol this metod is extremely easy! lol
now i have 23GB MyDocs and 6GB on Home!

Radicalz38, Thx!

thx alot here my partition table after repartition and get extra space for instal application:
