I just checked your product code 059J260 which points to RM-696 NDT LTA BLACK 16GB , this means it is Latin America(LTA, my guess).

But FW which is installed on your phone currently is of product code
059L6B8: N9 RM-696 Country Variant United Arab Emirates AE CLI8 Black 16G

This is very strange and depends on from where you bought you phone. Cheaply available N9 in market are done like that.

So you need to download file

Dfl61 Harmattan 40.2012.21-3.335.1 Pr Legacy 335 Arm Rm-696 Prd Signed.bin from following link and do cmt only flash.

If this doesn't work you can try other UAE product code fw files like 059L6B7 or 059N2D9.

If cmt only flash works, then you can flash any other emmc for content files but that is optional.
