    This is in no way a tutorial or official guide for doing such hardware tricks, but if i am not wrong, what guys are doing on hardware level is getting a 3.9 nordump or even the eeprom dump itself, and from this file, they get the first 2048 bytes, which is the 3.9 bootloader data. Then you take out your eeprom containing actual 4.6 bootloader, put in an eeprom programmer and implant those 2048 bytes at the same logical position. Add eeprom back to phone and it's supposedly working.

    3.9 bootloader was floating around on IRC not so long ago, but i think NORDump contains same data you need.

    But i can be missing something. Either way, wait for a post from whose which had, in fact, done it or are more in touch with Devs.
