Backup ORIGINAL IMEI/ EFS before unlock/superImei [ANSWERED]

[lexro93290]

Hello , i make this thread to ask to BST TEAM if there is a possibility to make a backup of EFS before doing "W defaut EFS" operation which as you know erase original imei for samsung with new security ?


Because some customer doesn't agree to see their Imei changed after unlock ....it is preferable to keep an alternative to restore phone's original state before start unlocking and give back their handset in case of bad situation ...


And if there is already a way to make a backup of original efs/imei/state please say me how to do it please ; then i'll keep a backup situation



THANKS

Hi, lexro93290

Some of samsung phone (exynos base) can read superIMEI (certs), so you can make as you said: read superIMEI > unlock > write superIMEI back.

we cannot read superIMEI from qualcomm base phone yet.
