[Thank you Sir for replying my question. I've actually tried reflashing 3 times but all same result. I think I might take your suggestion and flash the Beta firmware to see if it help or not.
One last thing make sure your USB Thumbdrive is FULL Formated FAT32 (Not Quick Format) I know I had issues once with FW that was cured with a FAT32 formated USB Drive. It was like NTFS worked but FAT32 worked properly.
Also I had issues with some brands of USB Thumbdrive, I found my Kingston DataTraveler 16Mb works really well. So maybe try with a different make of USB Thumbdrive.
I always flash using Safe-Mode method (As Recommended by Mikael - AC Ryan Staff)
I know it doesn't make sense but then neither does something that should work but doesn't.
