ZTE Packages Expert for Network Configuration

I'm in dire need of a Telecommunication Engineer, specifically experienced in both hardware and software aspects of ZTE packages.

For the packages, first of all I need B8200 board software packages like: FW-LTE-5.50.20.20.pkg, LTE-FDD-SW-5.50.20.20.pkg SW-UMTS, NB-IOT and so on.

Also UME R18, Elastic NET UME GULN-ITRAN-5.55.29.19p20RKJX, LMT, U31, OMMB are needed for those 5.50 packages.

Also I need ZTE account for support.zte.com.cn for downloading docs from ZTE.
