So this is tutorial that i'm putting together after i bricked the signal of my phone. It took me week of digging and learning of usb debugging tens of posts read and I managed to repair it plus additionally unblock various regions in radio settings menu (*#*#4636#*#*).
I should mention that there is no warranty on anything I'm about to write
Step by step:
1) phone has to be rooted and has superSu so flash it with appropriate rom
2) download and install following:
https://mega.nz/#F!RA83UTjA!M4v2djifO27mcL1OSzO9Ew
3) Download and install android SDK package
4) set your phone to USB debugging
5) on your PS go to \Users\(your user name)\AppData\Local\Android\sdk\platform-tools
hold SHIFT+right click--->Open command window here
Have your phones screen on and type in command window on your PC :
adb shell (enter)
su (phone will ask to grant permission)
setprop sys.usb.config diag (enter)
6) Go to device menager--->COM Ports-->Hs lenovo diadnostic click properties and change driver to the one you downloaded. It should come as HTC diagnostic
7) open QXDM Professional (you downloaded) go to Options-->Communication-->target port. Now set the COM port where your phone is installed. Go back to the main window and from "View" dropdown menu select "NV Browser".
8) You will now locate following lines and change their values to the one i provide(remember to backup original values). Select item hit "Read" change the value then hit "write":
441: 0x380
946: 0x0FFF
1877: 1970325105345408
2954: 0
You might have some values already on your phone...I messed mine in the first place so I'm not sure which ones are original
9) go to your phone deselect USB debugging then restart now you should have additional menu to change band settings in *#*#4636#*#* phone info.
10) to unblock additional LTE bands (experimental) go to this thread:

11) to improve signal strenght edit build.prop on your phone located in /root/system
find line "ro.ril.hsxpa=1" and change the value to 2 then start adding lines as follows:
ro.ril.enable.dtm=0
ro.ril.gprsclass=10
ro.ril.hep=0
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=8
ro.ril.hsupa.category=6
ro.ril.enable.a53=1
Some of it might not work for specific countries/carriers so just experiment
