Well.. my new DX comes tomorrow. Went to Verizon..they tried to fix it (same thing here..error code bootloader screen), but he came back to me and said that after extensively talking with Motorola, that there's no fix at this time because the software update is so new and that others (obviously we know that) are having the same issue. He said NOTHING about or asked anything about rooting.
Overnighted me a phone..comes tomorrow free of charge. Yay! I just hope it's not a refurbished one..I asked him if it would be, and he said most likely not since the X's are so new.
HTH..
