I have a samsung g610f that came hanging on logo.I then tried to flash it using z3x and it failed in the middle of flashng.Now when i try to enter into download mode it just shows power reset or unknown upload mode.At times it shows FORCED UPLOAD by key pressing.I have also tried to use the download mode jig and the 300k tool to try and enforce the download mode without success.Can anyone point me in the right direction to repair this j7 prime
