Hello

I want to install custom emmc from here EMMC_By.MiDO.FaYad.8.giga

I just want to know if I install it then will it delete my installed applications, messages, bookmarks etc?
Do I to have to backup my data?

Do I need BackupMenu V2 - OS backup & restore to backup or I have to use Nokia OVI Suite.

Thanks

Yes it will remove all your files on your n900.

Well, what do you think? Whenever you are reflashing the device what happens?

I read here that

Note that flashing eMMC will delete the /opt directory, so you *always* need to reflash your rootfs (the COMBINED image) after - or same time as - flashing eMMC (VANILLA img)

So Is EMMC_By.MiDO.FaYad.8.giga a combined image? or I need to download rootfs image from some where aswell?

It means I have to backup every thing but for apps I have to re-install them after re-flash.

What method do suggest for backing up
1. Messages
2. Contacts
3. bookmarks

For same games like AngryBirds and AngryBirds Rio I want to save the highscores.
Can I just copy the

Code:

/var/opt/rovio/angrybirds/highscores.lua

for AngryBirds
and

Code:

/home/opt/preenv/usr/plam/applications/highscores.lua

for AngryBirds Rio

Do I just copy paste when I have re-flashed the emmC.

I recommend using the stock backup program for application settings, contacts, calendar etc, and BackupMenu for the rootfs/optfs. You will need to copy the backups off the device before you proceed.

Once you've done that you can repartition the EMMC without wiping everything. You reboot the n900 with BackupMenu (by leaving the keyboard open) ang go into USB Mass Storage mode, and then plug it into your PC. You need a partitioning software to do the rest. I used GParted on Ubuntu. Here's a link for using a LiveCD.

Edit: the image you are using is a combined MyDocs/Optfs partition. So yes, you would need to get hold of a firmware image this page has all the info you need.

Sorry for asking a question which may sound dumb
With this method I don't need to flash emmc image? As I can repartition via this gparted
