Lenovo Z6 Pro Unlock all bands - Lenovo Z6 Pro Questions & Answers

Does anyone know if it is possible to unlock all the LTE bands on this phone? With the current enabled bands it wouldn't really work in the USA which I live, but wanted to see if it was possible.
Thank you in advance!

Bands are hardware. Best thing to do is to move out of the US.

Thank you for that sarcasm
As the link below states it has been done, but it is from 2014 so I just want to know if the hardware for this specific phone supports it but the software doesn't

Unlock LTE bands

Is it possible or will it be possible to unlock LTE bands on the chinese version?
no
So it will never be possible then? I've seen threads were they have unlocked bands on phones like OPO, S5, G4

I think its possible. If you can change bands for quallcomm SOCs(Like OPO, One m7, m8). But I think we need guide for this.
I've read this time around the modem is a different SKU depending on what version of the phone you have so I do not think it will be possible.
Of course you can activate the software... But you don't have the hardware antena...

May I ask where have you read this? What's the source?

Trying to unlock bands (e.g. LTE Band 4, 20, 28)

As you might know, the Mi 6 was announced today. The specs look great for the price (see http://www.pcadvisor.co.uk/new-product/mobile-phone/xiaomi-mi6-news-release-date-price-features-specifications-3653263/) and I thought I finally found the phone I really wanted.
But then the old story hit me again. No support for LTE band 20. As I live in Germany this means no matter what provider I have, I will be affected with less LTE coverage.
So I created this thread to gather any news that involve the possibility and efforts of unlocking the LTE band 20 on the Mi 6.
I hope there are maybe similarities with the ongoing efforts of unlocking the bands of the Mi 5 (http://en.miui.com/thread-242834-1-1.html or here https://forum.xda-developers.com/mi-5/how-to/progress-trying-to-unlock-bands-t3337476).
When the Mi 6 is shipped, I hope this will get some attention and we may find a way to unlock it together. :fingers-crossed:
I have the Mi Note Pro and I never spotted anyone succeeding in unlocking band 20.
I live in France and band 20 is one of the 3 main bands but I never suffered any need for band 20. I even had a Sony Z5 premium which had all French bands and I had to switch to 3g because it wouldn't receive well when I am in bed.
Depending on your carrier if you have just another band and live in a city, not having band 20 is not a deal breaker in my humble opinion.
If you really need it I wouldn't wait for sure for a way to unlock band 20.
Mi6 can work with AT&T network?

Yes that is a valid point. As I live in Berlin I won't have any problems here. But since I travel around a lot for work countryside coverage would be a good benefit. But as you mentioned band 20 won't stop me from getting the Mi6.
This thread is just if anybody comes up with a good idea on how this could be done. Just as a 'bonus'.
The most active in unlocking lte bands are people in the OnePlus forum as far as I know.

Because it needs to do a lot, such as patents, internal structure, and so on.
Maybe Xiaomi note3 will behave better.
Band 20 in mi5 CAN NOT be unlocked. It is hardware limited. Please read thread mi5, page 76.
You only need schematic diagram, then you can see.

It depends on power amplifier and rf modules. In some case it can be unlocked with software or hardware changing.
If somebody find which power amplifier and rf modul are used in mi6, let me known, i tell you if unlock possible.

But still shouldn't the network setup be kept stock... I mean why waster resources on a freaking modem... When u can divert them to something else....
And if I am not wrong Qualcomm​ gives the chipset/modem with all the bands unlocked.. quite like apple .. hence making s truly global phone

You could say the same for Oneplus's global and China variant. They must have their reasons. I'm sure everyone, let alone, Xiaomi, know that they don't benefit for locking the bands. So, there's no point speculating on why and rather to just accept the obvious that it was not for the US market or any other country that It's not being sold officially.

What is your phone model (601/602) ?
ATT/Verizon use which bands / spectrum for LTE ?
I am trying to buy one and before I buy it need to confirm whether I could use it on ATT network
ATT LTE bands:
1,2,3,4,5,7,17,20,66

You can but corrupt IMEI/hard brick is a real danger. In some cases only a JTAG board can help you revive the phone.

I assume you know the difference between hard & soft brick. In case of a hard brick, you will have to revive the phone first before flashing your modem backup

I just moved to LA, USA and confirm that At&t works on this mobile but only band 5(850). I tried T-Mobile and 3G/4G/ LTE didn't work except 2G.

Can Mi9T's firmware on K20 bring new lte bands?

That's the question holding me before buy one of these models. I need B28 lte band present on Mi9T but K20 is cheaper than Mi9T.
Can somebody try it?
Dont expect any more bands than what already is on the device. LTE bands are configured on Qualcomms firmware and that's not something we can change at this time or probably ever. Dont buy a new phone with that expectation. You will almost certainly just brick the phone so no one will try.

That was with a leaked tool for old SoCs. Currently we can't do anything about snapdragon 730 or 855 and similar and probably won't ever. It's better to not purchase this phone with the expectation that you can, it's very unlikely to ever work.
Somebody on this forum bricked his phone trying, just search.

network band limitations

are the network bands limited by the hardware or software?
do i need to buy the in2015/2025 to get 5g on tmobile or can i flash the correct region rom onto a different device?

It comes down to the hardware (radio/baseband modem, afaik) being able to 'listen and talk on' a given band's frequencies. But bands could certainly be disabled via software. Not sure of any OEM who does that, though.
