Hmm, I read a little closer this time and saw something I didn't notice the first time about the USB cable. He should still go back to stock (doesn't seem to matter how stable the ROM is; once you start having problems you need to go back to stock for some reason). He might also need a try a new USB cable as well. There's no reason it should work from the bootloader. aindfan, what happens when you start the phone in the normal bootloader (not the triggered bootloader) when you have the USB cable plugged in? It stays stuck on serial? Have you tried a new cable and/or other USB port (or possibly another computer?). Regardless, you're going to need to get the stock ROM back on there before going back to Sprint, even if you have to download it over Wi-Fi or something.
