Flash/Recover EFS [Snapdragon only]

Hey guys, i encountered many people complaining about lost efs and what not. So here i am giving everyone a new trick to flash efs. I hope this helps others.

Now, efs partition consist of thre sub partition, that are:
1. modemst1
2. modemst2
3. fsg

All three partition are important and contain imei number and wifi mac address and bluetooth address. Now i will be giving you tips on backing up your efs or if by some chances you lost that partition, then flash another efs.

Backup: Type these codes in terminal emulator.

Code:

---

su
dd if=/dev/block/mmcblk0p13 of=/sdcard/modemst1
dd if=/dev/block/mmcblk0p14 of=/sdcard/modemst2
dd if=/dev/block/mmcblk0p16 of=/sdcard/fsg

---

Now these 3 files will be created in the internal sdcard. Copy/move them to pc and save them somewhere safe.

Restore/Flash:

Code:

---

fastboot flash modemst1 modemst1
fastboot flash modemst2 modemst2
fastboot flash fsg fsg

---

And this command will flash the efs partition completely.

For those who have backed up before, can flash using the above method, but what about those who don't have a backup and want to flash this to recover imei. Well worry not, i have backed it up and willing to share this with others who wish to have their imei back.

Restore IMEI completely:
Remember, the file that i shared have my imei, mac address and bluetooth address, so you will have to tweak it after flashing. Don't worry i'll help you along the way.

1. Flash the 3 files following the above commands.
2. Use the imei changer.
3. Reboot and enjoy.

Note: Thsi procedure only changes the imei. Wifi mac and bluetooth add will remain my own. You will have to use 3rd party apps to change wifi and bluetooth address. Sorry but i don't know about those two.
