You can't crossflash with SEUS and CDA trick. SEUS uses the imei to identifiy the phone model, the CDA only identifies the customization.
There is no G705 firmware available for download right now.
You can flash it with A2Uploader to a W705 or W715 if you want, it works. But you won't be able to revert to a G705 until the fw files are released somewhere.
