How backup and restore imei

So, you will need YOUR WORKING phone, root and terminal emulator ;)

For backup open emulator and write:

su
(your phone will ask you for root acces)

dd if=dev/block/mmcblk0p3 of=removable/MicroSD/mmcblk0p3.img

dd if=dev/block/mmcblk0p5 of=removable/MicroSD/mmcblk0p5.img
(MicroSD is name of my cd card, so if your sdcard name is storage you will use this command: ...of=removable/storage/mmcblk0p3.img or mmcblk0p5.img)

-now you have your imei restored in your sdcard :o

For restore:

you will need YOUR i say again YOUR backuped mmcblk, of you will use ANOTHER mmcblk0p3 you will get fake imei (some like 0004488xxxx) and your calling will never work.

so, open again terminal:

su
(your phone will ask you for root acces)

dd if=removable/MicroSD/mmcblk0p3.img of =dev/block/mmcblk0p3

dd if=removable/MicroSD/mmcblk0p5.img of =dev/block/mmcblk0p5
(MicroSD is name of my cd card, so if your sdcard name is storage you will use this command: dd if=removable/storage/mmcblk0p3.img or mmcblk0p5.img.....)

now restart phone , and open dialer y will see for some secund "actualising database of contacts"
then press *#06*

you will see your imei
