Gentlemen,
Please I updated my note 10.1 2012 GT-N8000 to kitkat 4.4.2 without rooting or usb debugging enable, then during charging it, i forget it around four hours it restarted, and all the time in download mode, i used odin, failed to open Com port, i tried to enter to recovery, failed. i tried to enter to bootloader, i thing it is locked, also when i tried to use odin, it tells that no PIT is found, any suggestion? (changed usb cable, uninstall kies and install usb samsung drivers, used different versions of odin with CSC,Bootloader, PIT ,PDA,modem, files etc... ) all are failing, seems that it is just locking itself... the only place i can enter, is when i enter press power button, and - volume (Volume downn), it would take me to ODIN MODE , Product name: GT-N8000, Currnet Binary: Custom, System Status: Official, RP SWREV: A2 and it is all the time Downloading Do not turn off target, even i tried to uninstall the battery for sometime, and i put it again... and if just insert it to the usb it would start directly to Firmware upgrade encountered an issue, please select recovery mode (which i can't enter to it, failed to enter by power + volume up) in kies & try again, also the initialization of kies is not supported, if used...
