Could be, I suspect the flash is damaged, it kind of makes sense now with the issues I've had previously with lost data and settings. Here's the output from sfdisk:

Should I repartition it? I'd have to say I've never done that but there's a thread on the topic here that looks helpful:

Re: Introducing ubiboot N9 (multiboot OS loader)
 

By the way forgot, is there anything to do with the problem in Harmattan OS in second device?

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Probably yes, the N9 device is pretty forgiving in that respect, it can usually be fixed without reflash just by replacing/fixing the thing that's broken in the first place... however to know what exactly to fix is more difficult :D

Usually people just are impatient with that, and do a reflash, as that will always fix it.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

OK thanks reflash back to closed mode -- no-preserve?:(

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Just take backups before you do that and you'll be okay.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Ups back-up in Ubiboot how: Still reserved empty screen for Farfary's Backupmenu?

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well no, I meant just the regular Harmattan backups, and be sure to transfer the backup archive to your PC. And also back up all your stuff on MyDocs if you'd want to wipe the device.

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Regular Harmattan backups? To me it's the one in settings and farfary's Backupmenu and last one can't be used with Ubiboot?

Re: Introducing ubiboot N9 (multiboot OS loader)
 

Well, there are basically 2 kinds of backups you can take off Harmattan.

The first type is the normal backup via the "settings -> backup" menu. This creates backup of your settings, messages, notes, whatever application data you have (or most of it) and the result is a new subdirectoty under MyDocs/.backups/ which contains 7 zipfiles and a metadata file.
This backup does not contain your applications, so to reinstall those you need to either reload from store or save the DEB's when you install applications.

The second type of backup is the type taken with BackupMenu or ubiboot maintanance console, which is a snapshot of the filesystem state at the moment it was taken.
This type saves the state exactly as it is, which is a problem if your state is not correct (like on your N9), as if you restore this kind of backup to your device after a reflash, you will get the device back in the (broken/faulty) state it was before :D:D

So, if you have a device in a broken/faulty state, you do not want to use the second type of backup.
