i have flashed my phone but IMEI has been changed automatically
and now when i want to change IMEI my NS Pro displays "operation failed ! "
and when i turn the phone on it shows this message for 2 seconds :
"user fault on illegal trial"
what should i do now ?

buy testbox 2,they say they can fix this

khm... in last 7 days i have 4 phones with same problems... :/

when i flash or unlock via NS pro - imei is 00000000000000000 or 0000;;;;00000 :/

and i try with UFS, UST and 3-4 cracked or free programs - but without result :(

p.s. meybe for your problem - you can flash with special files on NS pro support area - name of this files is full flash for repair imei :) try and give the repport.
