[Xiaomi Mi 5 Guides, News, & Discussion] pakidermo5000:
I do not know what drivers you are trying to install and what you want them for.

But use this how to here. It also has the drivers. http://www.androidbrick.com/ultimat...agon-xiaomi-mi5-imei-and-baseband-repair-fix/

This is indeed a bit weird. I would not say it is locked or something. If I remember well, there is a initial step of scanning all possible bands at boot time, so the phone gets a list of preferred bands.

This list is kept in the EFS at

/nv/item_files/modem/lte/rrc/csp/band_priority_list

/nv/item_files/modem/lte/rrc/csp/band_priority_list_Subscription01

/nv/item_files/modem/lte/rrc/csp/band_priority_list_Subscription02

I think that if B7 was already in the list, even though you get B8, it will first set B7.

Yes, this is what we are trying to do. WE have the B20 NVItems and we wrote them to the QCN. We are not sure about the changes that need to be done to the modem. Do you know which ones are they?

In 1+3 it does not work because the modem and QCN is overwritten at boot, but mi5 does not overwrite it.

Hi, did you manage to get the QCN for mi5s? have you seen if there is any B20 NVItem in there ?

They should be these ones
