If your console was in DEX mode when you formatted the HDD, that means the system memory still has DEX flashed to it. That console will only accept DEX firmware. Since you tried reinstalling your current DEX firmware (4.46.1), I recommend you go lower. I would try either flashing
4.41.3 or 4.30.2 D-REX from the official REBUG site. This may work because your system is tricked into thinking it's on 4.46 and won't accept firmwares of the same number. Try flashing a lower
DEX firmware.
