I have recently bricked my Note N5120, when trying to flash kitkat. Odin not detecting it, unless i drain the battery to 0% till the screen is flickering or off. I power up with USB then Odin will detect the download mode. With this, I am able to flash any file with Odin.
As for my case, just not able to recover corrupted partitions or hidden folders (?), i am looking for a Odin PIT file now. Wonder if anyone is able to extract it.
