I could repeate the procedure without errors (the new value was saved) but still it did not help... ;(
On the other hand it did not harm the phone so, u are not loosing anything for trying.

has anyone had success yet just order this phone for my fiancee at a super deal i see people got the nv values to stick but still no lte where any of you on custom roms and kernals when you did this?

After read all of the reply in the thread carefully, I found my Mi 4 is a TD-Scdma and TD-LTE version, so it seems really no hope there

How to install the diag driver?

 

[meet_mehul]

in my case driver is not installing what to do now

I've done everything like this described by olokos, but something must be changed for our device. Do step 1 and 2 like in the link, download the attached modified diag drivers for Xiaomi from this post. Next you enable the diag port with *#*#717717#*#* and connect your phone to the computer.
Now go on with step 11, but find MI_00 instead of MI_04 and install the driver from this post.
Do everything including step 33, then you disable diag port by dialing *#*#717717#*#* again, reboot your phone and you're done.


Now the question - many people discussed about enabling LTE on MI3, but this wasn't possible due to the Snapdragon built in this device... But in our MI4, there's a Qualcomm Snapdragon 801 MSM8974AC, which supports LTE. So, how to enable it? I think some NVs must be changed using QXDM!? Anything else?
