i try but fail

1.Install the previous firmware before 4.3 update using the 4 part firmware file which includes csc,modem,bootloader pda(this will get you your imei back)
2. root your phone(check xda for rooting) and install ES file explorer and partition backup granting root permissions to both apps
3.using es explorer navigate to efs folder and copy it to your external sd. backup efs and radio partition with partition backup.
4.flash 4.3 update with also 4 part firmware file. if you have 0049 imei, root your phone and install es file explorer. navigate to efs folder and delete efs folder, then reboot. efs folder will be recreated. copy the efs backup from step 3 to the efs directory and reboot. it should get yo your imei back. Or simply restore efs partition with partition backup app.
5. fix not registered on network by downloading patched mk6 kernel and modem for 4.3 firmware
6. reboot rcovery and flash mk6 kernel, reboot phone, reboot to recovery again and flash mk6 modem. reboot phone....enjoy
