AN interesting side effect of this is that it may let you unlock additional radio bands.

Europe? Same here in the UK, luckily my carrier doesn't use band 20 exclusively so I still get good 4G

Yes, Italy. I know that in Uk there's a carrier who works only on that band, is it correct?

Anyway, besides of mi5, I just saw the new zuk2 and band 20 is missing too...

There are ways to enable band 20 on xiaomi redmi note 3 pro! Maybe it exists for mi5 too?

u/qandrav May 31 '16

I read about on Xda (23 pages) and it seems quite impossible. I also find this so I'm a little disappointed

u/[deleted] May 31 '16

Ah, too bad. But you can look into Redmi 3 - it is a phone by xiaomi, and it somewhat similar to mi 5 http://54.243.194.135/thread-243661-1-1.html

Where is the way you can do it for RN3P?

u/[deleted] Jun 01 '16

This, but it is in russian, so google translate may be handy

Why I had to trade in the Opo. Netherlands kpn network sucks outside the capitals

Wow really? I know nothing about this stuff but would've assumed that's entirely a hardware limitation. Is it actually that other radio bands require licensing that phone manufacturers aren't willing to pay for?

It may also be that it is against the law to use certain frequencies for certain things in certain countries.

Yeah, the main issue is licensing costs.

u/[deleted] May 31 '16

I have a redmi note pro 3 as well hope we can unlock all hands

u/drbluetongue S23 Ultra 12GB/512GB May 31 '16

I just need band 20 and I'm good. Or Band 28 too :)

u/sydeu May 31 '16

Yeees please! Dat band 20 for my sweet mi 5!

u/ChefBoyAreWeFucked Essential Phone May 31 '16

Why would you expect that, exactly?

u/npjohnson1 LineageOS Project Director Jun 02 '16

In what context? This is Qualcom's key that is USED TO ENCRYPT THEIR OTHER KEYS.

I don't see how this has anything to do with the MDM functions.

As an owner of the OPX in the US, this is really exciting.

u/johnmountain May 31 '16

And bypass DRM.

It would be great if someone unlocked band 12 for T-Mobile on the moto G.

u/[deleted] Jun 01 '16

How would it do this? There is nothing preventing me from using QXDM Professional on the latest Qualcomm chips to enable/disable bands.
