hi,

i messed up my N900 somehow and now i have to flash the OS.

so what is the different between the eMMC and the other type of binaries in the firmware download section?

do i see it right that i don't have to reflash the eMMC?
that is what i understood after reading https://wiki.maemo.org/Updating_the_tablet_firmware

True, you dont have to flash the eMMC. Just flash the latest PR1.1.1 bin file to flash over your current root filesystem.

DO REMEMBER TO TAKE A BACKUP FIRST, SO YOU WONT LOOSE CONTACTS AND CAN EASILY RECOVER BOOKMARKS ETC!!!!

it depends.. normally you don't have to reflash the eMMC. Last time I've reflashed just the firmware my N900 was totaly unusable - some problems with graphics - menus were not shown, etc, etc... So I had to flash the eMMC and the firmware.

When doing this perform the firmware flash but without booting the phone (the -R command) and just flash the eMMC image after that.

The wiki page is really confusing at that point, someone messed it up.

thanks to both of you.

in fact i flashed my N900 some hours ago and was a bit disappointed.
after installing some of the apps i saw that all my old settings are still there! and i didn't loaded my backup back into the N900.

so for me it looks like you have to use both if you want to do a full reset. just like lomo did.

Hi! I have a question : someone know if you can flash the N900 and on Windows XP with SP2 because in the tutorial it says that you must have SP3! Thanks in advance!

You can try it and see - I was unable to flash the eMMC with SP2 (not tried with SP3 though) and ended up using a bootable linux CD.

just reflash plain os image first.

specially if you have music etc inside the device. you'll retain your settings at the same.

but if devices behaviour is strange at all after plain os reflash, I suggest to reflash the emmc too.

that's weird, i remember being told a while back to reflash the emmc first then the os :S i did and nothing really happened
i don't mean to cause any confusion here but i just want to know what problems might result from the reverse order of flashing and to make sure what's the right way as i plan on reflashing when (if) 1.2 comes out

look at the big red box. it says:
When flashing the eMMC content, always flash the FIASCO/Rootfs image first, then the eMMC. Do not boot up the device between the two!
that is straight from flasher-3.5 instructions by nokia if i remember correctly.
