[PROBLEM] Not booting into Kodi after update/restart

[postcd]

I have selected to update all packages from within Kodi / Xbian menu. It was installing, not shown it finished, but it prompted me for restart. I skipped for like 15 minutes, added update window to background. Once returning after 15 minutes, i have seen prompt to restart so i proceed. After boot, it shows Kodi logo. Then Xbian loading window for long time, then end up in TTY1 (login prompt) where i am unable to login as root, says wrong password. If if this is something you are interested to examine and likely will be able to improve. Let me know what to look for in files (i mean exact commands as i am noob), if you will not provide any command to filter out only necessary data and want whole log/s. I want to provide only in private.
Is there interest in this or should i flash the image again and restore /home ?
Btw. root password reset i have tried to do right before this incident from within Kodi / Xbian interface prompted if i am sure to proceed with change. I have clicked OK, yet Yes/No buttons was not highlighted, window went away anyway so apparently password was not changed because I have made sure to type right characters by testing password in username prompt on TTY.

"SOLVED" by copying latest OS image on the SD card and restoring home backup file i had handy
