I've installed an ATT 4.0.4 firmware from sbf.android.org in a China Cellphone. It's work, but I'm not able to install any other ROM as CyanogenMod, 4.1.2 official leak, etc...
I've tried flash some custom roms and sbf rom in RSD Lite, but for both return the message: "Failed flashing process 6/21 flash "cdt.bin" phone returned fail ...".
I looked for for CDT.BIN and I don't conclude WTF that file is , or how to fix that.
Someone knows somethings about it?
