Hello.

The problem is the Security was not wiped successfully, IMEI should be Unknown after wiping. In some cases, is necessary to repeat the "Wipe Security" operation several times or re-flash the phone. Try to do the next:

1. Fully charge phone's battery.
2. Make Factory data reset and wipe cache partition.
3. Root the phone and make Wipe Security several times and check, whether IMEI becomes "Unknown". Also try to re-flash the phone with different firmwares and make Wipe Security.
4. When the IMEI becomes "Unknown", Write Certificate.

Also, look here:

Also, You ctry to Wipe Security via phone's menu, as it is shown in the following video: https://www.youtube.com/watch?v=1DtPT2MmNhg.

Post here full Software log with all of your actions.

The problem is the Security was not wiped successfully, IMEI should be Unknown after wiping. In some cases, is necessary to repeat the "Wipe Security" operation several times or re-flash the phone. Try to do the next: 1. Fully charge phone's battery. 2. Make Factory data reset and wipe cache partition. 3. Root the phone and make Wipe Security several times and check, whether IMEI becomes "Unknown". Also try to re-flash the phone with different firmwares and make Wipe Security. 4. When the IMEI becomes "Unknown", Write Certificate. Also, look here: http://forum.gsmhosting.com/vbb/f684.../#post10681731, http://forum.gsmhosting.com/vbb/f684.../#post10705160, http://forum.gsmhosting.com/vbb/f684.../#post10708907. Also, You ctry to Wipe Security via phone's menu, as it is shown in the following video: https://www.youtube.com/watch?v=1DtPT2MmNhg. Post here full Software log with all of your actions.
