Reflash LTE modem, or flash whole firmware. It must reset nvram settings to defaults, according to messages above.

Add new port ---> Serial/USB Ports ---> Port: "COMxx" (put on the name of your port, mine was COM8) ---> Port Label: "COMxx" (same as before) ---> Ok, done..

Now, you refresh and go to QXDM:

Options ---> Communications ----> Port type --- > Click on your COM port

Target port: COMxx ---> Ok, done..


and all set to keep on at point 12!

As I have Claro here at Argentina, I must change my SIM to try if I got it running or not 7/28 (700).. As soon as I get it, I'll do a capture to confirm either if it works or not.

You tell us my friend

I'm on E+/O2 in germany. They send on LTE band 20 only. Mod tried on my Xiaomi Mi Max Pro (snapdragon 652): LTE Band 20 does definitively NOT work on THIS phone, maybe on others ... Seems to be hardware related ... Apart from that my Mi Max works normal (gprs, edge, hspa hspa+).

Thanks. Mi mi5 has 2 SIM Slot. I don't know what happened but both SIM slot cannot read SIM (after I tap some USA LTE 4 option). Now SIM 2 works fine, thanks to you, Still try to figure how to restore the SIM 1. Many Thanks,

Same case as you. Selected USA Band on SIM 1 and turned into "no service".
And then change sim card to slot 2 and everything going normal.
I've tested this method to my MI5 on sim 1 and now it work perfectly on both sim. I will try to insert "Smartfren 4G" sim card in slot 1
