Tplink mr6400 lte module

Installing and Using OpenWrt
1

Hi guys
I'm a newbie fo openwrt... I ve tried to install openwrt for my lte router tplink Mr6400 via tftp but after that I cannot access 4g internet. In wan interface there is no protocol for 3g or umts connection (only PPP static addrss PPPoE DHCPv6 client UNMANAGED), I've tried to reverse to original firmware but all the information about ISP and 3 g connection are disappeared (it s alla blank).
send command throught Shh adb shell give me an error in device, rmmod option > device not loaded and 192.168.0.1/login.html no connection.
How can I get back my connection? Maybe I ve bricked LTE module?

I also can t flash/restore via webinterface of original firmware that give me an error
