Hi,
Thanks for reply . i have done both still IMEI is 000000000000.
Bump
Any help will be highly appriciated
Believe you can't do anything about it, if you don't have an EFS backup, you can't "recover" the IMEI, Serial #, etc. You can probably use this and change the IMEI to a screenshot of your own IMEI, but I am not entirely sure if it works or not.
Hope this might help.
