I have Samsung Galaxy Note 5 with Lollipop OS. I tried to upgrade firmware through ODIN, but it showed an error as Custom binary blocked by FRN lock. I have the google account credentials but since then the firmware upgrade failed my phone only shows the screen as " An error occurred while updating the device software, use the emergency recovery function in the smart switch pc software ". I DONT GET ANY LOGO OR BOOT MENU.When I press and hold the power+vol Down+Home it goes into download mode and when I chose to continue it shows the same error. I can only go to download mode but the ODIN couldn't continue as FRN lock is on. I am badly stuck. Is there any Way I have a OTG cable and External OS with me, since that I dont get any Boot menu I have no option left. Please suggest me a utilty. I tried below ways, Recovery through Samsung Kies( Result: Says Wrong Model for some reason). Samsung Smart Switch ( Result: When I enter Model & Serial Number the Application closes in a flash.
