Perfect ! I have try to install Imei Changer with Xposed Framework and not work

Only one module change in *#06# the imei and set both slots with the same Imei, because however it does not support two imei numbers. But also in this last case nothing work, as if the module worked only at software level not at the radio level.
now I am looking for documentation about the decrypt of the EFSv2 format of the nv_data.bin file that generates two files in the folder /data/misc/radio, named ahrh and ahrh2 for second slot imei.
it is encryped using id model number but I'm at zero and I do not find much on the net
