Oh, I used the first method and there is not vkb available. I even thought of copy/pasting commands in terminal, but I forgot I can't click enter ;p Then I thought that maybe if I install the *.deb file it'll work but no. Still no vkb in setting available. I think that the cause could be already somewhere deep in the system, because I kinda have a rebootloop everytime I turn the phone on, I mean it reboots twice or more and at some point it stays on. I will flash anyway I think my N9 deserves it
