WELL I KNOW THIS IS AN EARLY STAGE OF ASUS ZENFONE 4 DEVELOPMENT AND THIS TUTORIAL MIGHT NOT BE USEFUL FOR NOW, BUT WHO KNOWS, THE ZENFONE 4 in THE FUTURE MAY OR MAY NOT GET DEVELOPMENT
SO EVERYTHING HERE IS JUST A PREVENTION OF LOSING imei/Radio OF THE ZENFONE 4, so after you cook a custom rom or do something which corrupts the imei/baseband, just take a backup and save it somewhere safe in your PC or CLOUD
SO ALL YOU HAVE TO DO TO HAVE A BACKUP OF YOUR imei NUMBER IS TO just type some lines in the keyboard
NOTICE:::::::****ROOT IS REQUIRED FOR THIS TO WORK****:::::
Instructions for backup
1. Download terminal emulator from GOOGLE PLAY STORE
2.Open terminal emulator and type
Code:
su
3.You will be prompted to grant superuser permissions, select grant(This will work only if you have root)
4.Now type
Code:
dd if=dev/block/mmcblk0p3 of=sdcard/mmcblk0p3.img
5.Open file manager and goto internal storage and check if there is a file with the name
mmcblk0p3.img [Its size is about 21MB] now keep that file in some safe place where it wont get deleted
Instructions for restore imei
1.Open terminal emulator and type
Code:
su
2.Now type
Code:
dd if=sdcard/mmcblk0p3.img of=dev/block/mmcblk0p3
DONE!!!!!
thats it..
