Hi All, Just picked up stock Tab 8.9, I'm fairly well-versed in rooting, CWM, Odin, etc. Enough to be dangerous I guess. I had a 5.0...version installed but in my haste I flashed a 5.5... CWM version that I only saw after the fact specifically warned that it does NOT work on the LTE version, but that is what I have (SGH-I957). Now, I get absolutely nothing. I cannot get any screen - recovery, download, Odin or otherwise, with any button combination that I try. As if there is simply no power to the device, whether plugged in or not. Battery was good before I did this. Any advice would be greatly appreciated. Thanks.
