After flash a rom,my gt-n7100 imei show 000490..........,S/N 000000000,H/W version not active or unknown and cannot make or receive any call,it show not register on network.So i ask a friend who work at a mobiles shop to repair it,now i got my phone back,the imei is correct and can make or receive call and everything is look like ok.Here is my problem,the S/N still is 000000000,H/W version are also unknown or not active,RF Call Date unknown,but i can make or receive call and my friend told me not to flash any rom again because the imei will collapse again.Can somebody help me,i can't stop flash rom,it just like heroin will get addiction.If i want to flash rom,which one rom i should chose.
