problem after install this rom [ROM] XDABBEB's VS98024A v1.2.1

[AC Question]

I follow the instructions and using this rom. However, I can't go to download mode anymore instead it go to fastboot, I tried to get rid of it but not working. My computer doesn't recognize the device when i use "fastboot devices". This rom doesn't allow t-mobile 4G or 3G. It doesn't work with other roms. I want to set it back to factory stock to root again. Now only thing i can do is calling and texting.
