Re: Nokia N9 black screen after installing Sailfish
 

Yes, it seems that probably there's*some glitch in your SFOS installation, just as @coderus says.

Fortunately now as you have once installed it, it is very easy to reinstall; just boot the device in ubiboot maintanance mode, and when you get the partitions exported, delete the files from ALT_OS partition and unpack the SFOS tar archive there.

There is no need to change anything else any more :D

@Coderus and @Juiceme, Thank you so much for the help you have given!
One last thing, I just did as you said, but how could I eliminar files from this folder ALT_OS? I want to type some string in the terminal of Ubuntu, for example: "sudo su etc ..."?
Why can not I move them to the trash. Excuse my ignorance! :confused:

Re: Nokia N9 black screen after installing Sailfish
 

So you are using the ubuntu file manager? I guess it does not give you sudo rights, hence you cannot delete the files with it.

How to do that in console;
- note catefully what's the mountpoint (could be /media/ALT_OS/ for example)
- go to that dirdctory
- give command "sudo rm -rf *"

Be absolutely sure that you are in correct directory!!
