Default Bootloop, no matter what ROM

I decided recently, with the release of towelroot, to root my Transformer. I was having performance problems since the Jellybean update, but the optimizations I installed improved it. There was still some lag though, so I tried to flash a Cyanogenmod 11 nightly. There were no errors from CWM, but the tablet stalked at the bout animation. I tried an OmniROM homemade, same story. I flashed the newest OmniROM nightly, the GApps package listed on the OmniROM thread on here, and the US_epad-user-10.6.1.27.5 kernel, no soap. I can get Windows to detect the tablet when CWM is in sideload mode, but fastboot never connects, so I can't flash another recovery.
