Domnloading Do not turn off target SCREEN

[wichiepr]

I try to install CyanogenMod on my Galaxy Note 10.1 GT N8013 and I get the famous screen Downloading Do not turn off target.
I try everything in the book from the forum, nothing work. To make thing worse now the USB is not recognized by the computer.
I drain the battery completely and soon I connect the charge BOOM the famous screen. LOOK to me that this is the end of MY NOTE? PLEASE any advice before I send it to sleep.

Thanks
