Backup, Generate & Restore IMEI

A factory reset of full flash may clean out the IMEI. So it is wise to backup and restore IMEI, or even generate a new file with IMEI

For MediaTek MT6516 the IMEI is located in one of these two locations:

/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001 (older firmwares)
/nvram/md/NVRAM/NVD_IMEI/MP0B_001 (rumored location for newer firmwares)

To backup the IMEI, simply backup the MP0B_001 file (using a rooted shell or adb)
cp /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001 /sdcard/MP0B_001_SAVED

To restore the IMEI, simply restore it, and set proper permissions (using a rooted shell or adb)

cp /sdcard/MP0B_001_SAVED /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
chmod 650 /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
