note 2 stuck on samsung logo - Android Q&A, Help & Troubleshooting

Hi,
Today I found that my Samsung Galaxy Note II (GT N7105) was stuck on the samsung logo which comes on startup. I restarted it but it still wasnt going beyond the logo screen. After that I went into recovery mode by pressing power, home and volume up button and it showed some messages like this:
E: failed to mount/efs (no such file or directory)
E: failed to mount/system (no such file or directory)
E: failed to mount/cache (no such file or directory)
E: cant mount / cache / recovery / last_recovery'
E: failed to mount/data (no such file or directory)
And many messages like this. I would upload a pic but I dont know how to upload it here.
After doing factory reset and wipe partition, it still stuck on the samsung logo.
(I rooted samsung note 2, about 6 months ago)
i m a newbie. pl show step by step how to get my phone working. Please help.
Thank you.

Problemes after he samsung galaxy 6.3 Gt-i9200 Root { Please Help Me ! }

I have a Samsung galaxy mega 6.3 (GT-19200), I had vcoreroot router with {VcR00T} and since my phone does not turn and remains blocked on the Samsung logo
I tried all the links to this problem but nothing, the logo is still there, but I have little unrooter with Odin and firmware and the phone still blocked on the samsung logo
In the links, we wonder just reset the phone in RECOVERY mode.
When I put the phone into Recovery Mode I find myself with too bizarre entries:
E: failed to mount / data (invalid argument)
can not mount '/ data' (invalid argument)
E: Failed to mount / data (invalid argument)
E: Can not moun /data/log/Recovery_log.txt
And when I try to use the factory reset, I like to write:
MDM do not allow factory reset.
Phone Will REBOOT automatically.
How can I settle this problem? :crying: :crying:
