Root Can not install any firmware on GT-N8010

[MarianMarian]

Hi everyone I've hope that you can help me. I've got Tablet Samsung Galaxy GT-N8010 . An when I go to download mode there is something like that :

Odin Mode
PRODUCT NAME : GT-N8010
CURRENT BINARY : Samsung Official
SYSTEM STATUS : Official
RP SWREV: A2

I try many solutions , try with another ROM but it's still not work. I can't go to recovery mode because there is "firmware upgrade encountered an issue " What can I do more ? Thanks for any suggestions
