Hello, i've recently done these customizations to my N920C:

Here is what i did: Stock 6.0.1 non-root > install TWRP recovery > Install Custom ROM > Instal new Kernel (rom does not have it) > Factory reset (cleared cache/dalvik) and advanced -> wipe internal memory.

From now my phone won't boot up. As my friend says, there is no OS inside.

I downloaded 5.1.1 stock ROM and tried to flash it using Odin. The process is stuck at "SetupConnection..." and won't start installing when the phone is in download mode.

A weird thing: before my download mode had some text in the top left corner and right now it won't display "Odin mode", just blue screen with "Downloading... Do not turn off target"

How do i install stock firmware? Any help is very appreciated!
