Backup, Generate & Restore IMEI

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



Code:
 /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)

Code:
 su
 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)

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



you can even apply new IMEI by generating a brand new MP0B_001 file. Download their IMEI generation program imei_mtk6516.zip, use the correct executable (PC, Linux, ARM provided) to generate a new MP0B_001 like this:


Code:
 imei.xxx <15digit_IMEI_1> <15digit_IMEI_2>
