So I had my merlin built running on my t-mobile asus 68u. Last week I was trying to upgrade to the newest merlin build 378.56-2 but I stupidly downloaded the wrong version 3.0.0.4.374.35_2 and uploaded to the router. Now I can't go back to 378.56-2 anymore no matter how many times I try to upload the firmware it stays at 3.0.0.4.374.35_2. Can anyone help me please? Thanks
