Siguiendo con las dudas y desconfianza que tenía acerca de si verdaderamente se encuentra el IMEI en alguna de la carpetas de /EFS y que posteé en mi anterior reply de este post, he seguido investigando sobre este tema y parece que a día de hoy aún no hay método para realmente hacer backup del IMEI en el S4 Mini:

Normally, phones IMEI in previous galaxy devices (don't know about current S4, I own S4 Mini LTE), was stored in nv_data.bin file which was located in /efs folder on root. (which is a mount point for mmcblk0p10 partition in S4 Mini LTE). But, in this device, there is no nv_data bin file and IMEI is not stored nowhere close to efs partition. Not too many people own S4 Mini's and almost everybody whom I asked an information based their knowdledge on another devices and were feeding me false information I heard over and over again.

To clarify something, I know, that EFS partition doesn't contain IMEI, because:

• No file in efs mount point contains IMEI.
• No IMEI found checking EFS Professional backup (tar) on HEX level using various search methods. Even through-looked it, file is not that big.
• No IMEI found through-looking .raw backup made using cygwin (which contains every single byte of partition, even though it is not a part of a file), which is 95+% warrant, that IMEI is not in EFS partition.

Así que por si acaso, no os confiéis al trastear. Chucky no sé si tú que estás mucho más puesto en este smartphone puedes confirmar o desmentirlo, yo llevo sólo un mes con el teléfono y estoy de acuerdo con lo que dicen en XDA, porque no he visto el IMEI en ningún fichero de los que hay en /EFS
