[Q] How to restore a full backup - Nokia Lumia 800

[davortsan]

Hi all,

This morning I have installed the RainbowMod ROM in my Nokia Lumia 800. All seem very beautiful but I have a big problem for me, I can't use my Windows Live ID account, Authentication failed error is always showed.

This is the main reason because I need to restore the full backup that was generated before to install this custom ROM. To generate the full backup I executed the following command:

sudo dd if=/dev/sdc of=~/fulldump

Now, I would like to know how I could to restore this fulldump. Could you tell me the steps to restore it, please?

I have another doubt about the restore procedure: during the RainbowMod flashing I had to flash the amssadsp.img_part3 file on /dev/sdc3. When the fulldump will be restored, will /dev/sdc3 be restored too, please?

Thanks in advance.

Cheers

David Ortega.

Did you end up with one single file or with on file of each partition? Have you created a Zune backup as well?

Hi ChrisKringel,

I only have one file (16GB). I didn't generated a backup using Zune so my only way is try to restore the file (fulldump).

Thanks a lot.

Cheers.

Have you tried to DD it back onto the device?

I found that the following command should resolve my problem:

sudo dd if=~/fulldump of=/dev/sdX

But I would like to confirm it with the gurus

Thanks a lot
