Trying to unlock bands (e.g. LTE Band 4, 20, 28) - Xiaomi Mi 6 Guides, News, & Discussion

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.

Current Ascent Mate 7 is not US-carrier compatible, a new model being release will be

My apologies for the multiple threads. If the moderators see the other one, please delete it.
i spent part of tonight emailing back and forth with Huawei's customer support. You would have to scroll through the public emails I posted and their public responses. What I don't get is why NO reporter NO journalist NO ONE in tech thought to ask Huawei straight out if there is ANOTHER model coming out for the US market? NOTHING I've read talked abou it, so, I asked them, and they responded:

Huawei Ascend Mate7 specification is the same, but the 4G frequency is not the same, it support 4G LTE FDD Band 1/2/3/4/5/7/8/20/28(Aphase), It will be released in the United States.

But with all those LTE frequencies, doesn't it kind of have to be compatible? AT&T uses band 2, 4 and 17 so this phone should work on AT&T LTE since it supports band 4.

Thanks for the youtube link. I think I'm going to wait until I know that it is supportrd by T-mobile's LTE network. He states in the video that he put a T-mobile SIM in therr and it worked fine, just want to double-check with Huawei and see what they say. It's a lot of money for a new devuce, just want to be sure.

Don't waste your time ask Huawei service team.. They doesnt know the phone much than you.
There is 2GB+16GB ROM version FDD-LTE band: B1/B3 1800MHz/2100MHz
3GB RAM+32GB ROM version FDD-LTE band: B1/B3/B7 1800MHz/2100MHz/2600MHz
T-Mobile FDD-LTE: 1700/2100 ?
There are only B1/B3/B7 now because the MIIT(Ministry of Industry and Information Technology,Chinese Telecom manage department) limited.
You will enjoy more bands after un-limited-- Need 2-3 months since Chinese FDD-LTE marketing develop slowly.
Yes, Need flash NEW ROM un-limited then.

This still doesn't answer the question as to why the hell the Mate 7 works on T-Mobile LTE (at least according to the guy that reviewed it in the video). Huawei says it doesn't, your spec images say it doesn't, but it does?

If the T-mobile LTE band is 2100MHz, works no problem.
You will unlock the band after NEW ROM released out.

THIS is why it makes sense to wait. The device is very expensive. rather than plunk down that kind of money for something that "may" work with US carriers, wouldn't it make sense to just wait and see what else is released?

Just because it was working doesn't mean he got full LTE speed. As far as my research took me Band 4 (AWS) of T-Mobile uses a 2100 MHz range downlink and 1700 MHz range uplink.
Specs on the Huawei site lists a whole slew of bands, including band 4. It is strange though that sellers on Alibaba and emails from oppomart.com state to the contrary. I just asked oppomart about this and pointed them to the Huawei spec page, and they said then it should support band 4...

I am guessing (keyword) that it may be like the Note 3 where Samsung will say no but realistically the phones are all the same regardless carrier. You would just have to unlock a Big 3 phone and you would be good to go.

Is it likely the V20 will get decent Dev support/activity/ROMs?

So I've been looking through the V10 Android Development threads and wondering what it's been like on XDA with the V10 in terms of Dev support/ROMs/ etc. I've asked over there for feedback. Doesn't look like there's been much interest in the V10 phone from Devs? Is there a reason why? Locked bootloader? No "sources" released? Is there a CM ROM available anywhere?
Reason I ask is because I'm seriously considering getting a V20 which looks like a great phone and I've always had Nexus phones in the past. Currently rocking a Nexus 5 which I still love. The V20 looks to me almost like a larger more modern and advanced Nexus 5 (both made by LG). The G5 I saw in a phone shop and it really didn't appeal to me (build quality seemed poor). What's the likelihood the V20 will get decent Dev support? Is there anything that will make it more likely?
What specifically was wrong with the G5 build? My wife has the phone and we both think its pretty nice. At least as good as the Galaxy it replaced and probably a bit nicer.
I'm also interested in your original question. How much support will this phone get and will the boat loader enforce secure boot?

v10 was abandoned in short order after the bootlooping SNAFU.
This phone is starting life too expensive, unique snowflake hardware SKUs for every US carrier, And more than likely a locked bootloader (hopefully it can be unlocked). All those combined are a development death sentence. Assume no development, and be happy if there is any. Combined they make people who can develop firmware not even want to bother.
Remember the v20 has been on sale in Korea for a month now. How many buyers/users even post on XDA about it? Basically none AFAIK. There should already be a development charge, and maybe a root worked out or at least actively being tested. And there isn't any, not that has been made public.
lol dude we get it. every post of yours is the phone is too expensive and there's carrier versions of it... like every. other. phone. if you're so upset by price and carrier versions, why are you looming around these forums? go buy a 300 dollar phone and stop trying to sell everyone else on your opinion.

Considering there is an unlocked US model that seems will work for all carriers, I would think that would be the one that gets development and is quite conducive to it.
No development is getting slowed down because a phone is $800. That's the new norm if you want this high quality of a phone. Pixel will get tons of development, Note 7 was actually going really well despite the $864 price, and many others will too. The fact that it's LG and people overlook the brand continually will be the primary reason for lack of development, if that's the case.

Say what?
The unlocked version WILL NOT WORK on Sprint at all (the model # and IMEI range will be completely wrong to pass their whitelist)...and unless you have an already active SIM, your new VZW SIM will not activate as the model number is wrong and your account will show "unauthorised device". This of course sets aside the problems of radio bands that are missing or wrong for your specific carrier. So at best you'll have poor service if any depending on where you are and the tower deployments in the areas you travel. Also we don't know how updates will be handled on the unlocked device--take for example recent Nexus devices that got carrier fed updates rather than direct from Google (although that at least was an option if you ADB'd factory images) Every carrier is a unique SKU with unique firmware. You may never get updates even from LG (it is a serious possibility and risk).
I hope you have lots of cash hoarded when your $800 gamble, that it will work on all carriers, screws you over
The ZTE Axon 7 could be a much better device with much more development potential that is 50% the frickin price. "$800 the new normal" indeed. Buy an iPhone 7 for less cash, not an iPhone wannabe with less long-range OS support and let's be honest worse standby battery life. Because yea let's be honest, in 12-18 months LG will quit updating the device while in 3 years the iPhone7 will probably still be getting OS updates.

Because folks ask questions...and get tremendously wrong answers. Like "the unlocked version that will work on all carriers". Echo chambers benefit no one. Until you see and know what having a unified hardware platform (like Nexus) does to accelerate development you don't get how screwed over you are by unique snowflake SKUs.
I too was excited for the v20, but LG fumbled the ball. in 3 months when the price comes down from the early-adopter surcharge (hopefully) I'll think about getting one. Depending on what I see.

Um, the unlocked version has all the Verizon bands and is completely compatible with all carriers from everything I have read.
The iPhone 7 is not a valid comparison at all. Different type of phone. iPhone 7+ model with more than 32GB of storage... That'll set you back over $800, like these other phones.
You're clearly an Apple lover so I'm not going to bother continuing to argue. LG V20 >>>>>> iPhone 7 that it's absurd to even compare, for me. I'd be really unhappy with that iPhone because it still lacks most qualities I desire in a phone. To each their own.

Then you clearly need to read more, not repeat flat out wrong info. The unlocked version is missing IIRC 1 Verizon CDMA 3G band (of 3), it is missing IIRC at least 1 WCDMA bands (out of 2 or 3), and it is missing IIRC 2+ LTE bands (Of 6 or 7 OTTOMH). The FCC filings showing that are available online. The same way that the unlocked version is similarly missing Spring CDMA/WCDMA/LTE bands. The radio support IS NOT THE SAME between VS995 and US996 and S997. It is NOT "completely compatible"-it is only sort of compatible....presuming it gets past carrier whitelisting of the IMEI and model number which on Sprint it 100% WILL NOT DO, and on Verizon it probably will presuming you already have a working SIM....then you have other problems to worry about (radio band support and updates).

I'm not an Apple lover at all. I'm fed up with Android OEM shortsighted foolishness.
The unlocked version also doesn't have AT&T's bands 29 & 30 and T-Mobile's Band 66. Personally, I plan to get the AT&T V20. I don't mind the (expected) lack of updates so much as long the current version doesn't have glaring bugs. For AT&T you also need a branded device for VoLTE.
I currently have the Nexus 5 and Google left it with major bugs for a few months (one of them was broken car Bluetooth). So my experience with Google wasn't that great. The Pixel devices look like bad iPhone and Galaxy copies.

Interesting. I'll look into it more.
I honestly don't care about development anyway - I left my Note 5 alone and loved it. I'm planning to do the same with the V20, but I do hope there is some development eventually just for fun.

The development is what I find cool. It is why I keep ending up being a tester for ROM teams (did it on Note 2, and still on Nexus 6)....but Android generally is getting really f'ing annoying on some of this crap. SafetyNet for example isn't just a framework for AndroidPay and stopping you from using your phone from paying for a burger due to Xposed, corporate email servers are now using it....so if you modify your firmware in any unauthorised way your employer may well not let your phone talk to your work email servers anymore (one of mi amigos on Team Twisted has this problem-nothing we can do). Google seems to be wanting to go iron-fisted in security and sacrificing FOSS development for "security".
There was a post on r/Android tonight outlining some of the more obscure technical problems, and outright annoyances for developers as well in the current Android landscape generally: https://www.reddit.com/r/Android/comments/56qr4z/why_i_am_giving_up_on_android/
FWIW....he mentions specifically kernel 3.18; that kernel is not only used by the upcoming Pixel but according to the posted v20 system dump, a few subforums down, is the kernel v20 is going to ship with as well. When that OP is speaking about shipping a brand new device in Q4 2016 with a 2-year-old+ kernel ceasing upstream patching in 2-3 months as being insanity.....he's not just talking Pixel, he's also talking v20.
I wouldn't borderline rant on it unless the device had a ton of potential...which v20 especially does, and seeing LG squander it with shortsighted planned obsolescence is frustrating.
Personally I am okay with not too many roms. All I need is root for Viper and a few other apps.
I really think that I'll get this phone to replace my G4. I had to come to terms that the bootloader will never be unlocked on all models except T-Mobile and certain international models. I've also accepted that there will be absolutely zero dev support.
Don't fault me for being pessimistic. Being optimistic with the possibility of Dev support and observing how the G4, G5 and V10 turned out is plain foolish.

Their listing for the VS995 is incorrect/incomplete compared to what the LG Electronics sent to the FCC and has on file. Read and compare, some of their entries are wrong (VS995 does indeed have Band 25), some like Band 66 are left out or missing (VS995 has that too). WCDMA is either seemingly absent although maybe they call that "UTMS". CDMA support is also flawed (should be 850/1900 for VS995 not 800/1900). I don't have easy to call up numbers for US996 ATM, but one way or another-their band support table is incorrect.

The phones are not radio band identical.
Yes the US996 is compatible with Verizon. I will have it on their network within 30 minutes of unpacking it from the box.

Actually, devs that tried supporting Note 7 are now interested in developing for the V20 from the online polls since the note 7 has been officially canceled

LTE FDD Band 20 - 800 MHz support

Apparently there is hardware support and band 20 is unlockable - For Mi5, some users say certain hardware components are missing, others say that all hardware is there - from RF filters, RF components, SAW filters, etc. and that only RF calibration (software) is missing. The thread is here: https://forum.xda-developers.com/mi-5/how-to/progress-trying-to-unlock-bands-t3337476
Can anyone confirm? Any schematics for Redmi 4 Available?

i searched a lot for that, if it can be done i haven't found a guide on how to unlock band 20. a few other bands yes but not 20 unfortunately. if you are luckier than me please report back.
edit: check this thread. i cannot do it right now, but if you try it please let me know

First of all, are you in an area that is covered by that 4G band?
Second, have you tried to change the NVRAM settings?

I Have redmi 4 pro and connected on some area with 4G. Connection is really fast. I don't know if my device have B20 band etc. How to check that.?

maybe, but indicator 4G is fake? also fast browsing with this.
Also shown H, H+, E.
b20 band is one of few LTE band. Not supporting b20 does NOT mean that your phone does NOT support entire LTE standard. Just b20 band.
I'm everywhere and everytime in 4G with Vodafone (in Italy), only some carriers use b20, the phone support 4G.
In my coutry cariers uses mostly only 800MHz (B20) and 900MHz (B8) so I triend to unlock it. And I can confirm you can't unlock LTE bands via NV Browser on our phone! While I was testing it, I bricked my phone so I don't recomend to do this for newbies.
PS: My phone is fine now I got him back from the silicon heaven
I tried changing the nvram, too. But it does not work... you can disable more bands with the nvram value but not enable anything ....sadly Dunno if this is hardware restriction, modem firmware or other software.
If there's a way to unlock band 20 (800 mhz) please let us know

Xiaomi Mi Mix 3 5G on T-Mobile and unlock 5G bands if possible...

Hi I am interested in buying the Xiaomi Mi Mix 3 5g mainly because T-Mobile is going live with 5g where I live on Decemeber 6th 2019. But from what I know the this phone doesn't support the 5g bands for T-Mobile.
I heard that there is a way to unlock those bands on Qualcomm devices and this phone uses the Snapdragon SOC.
Can this be done?

So the bands for 5g that tmobile supports is not dependent on just the processor, its also dependent on what the manufacturer decides on. As with all phones, you need to see what is the most compatible cell phone provider for that phone. If the mi mix 3 does not support tmobile bands, there's no way to force it to.

Correct. I've had a discussion on a Mi Mix 3 5g thread where this guy says it's a update thing not a hardware thing. Which I feel he's clearly wrong. Cell bands have nothing to do with updates, it's a hardware thing.
Dear slimegpod,
The frequency is supported in hardware but we did trials and only the Vodafone and global rom version has the Vodafone de 5g Network activated.
So I am on eu rom and cannot use Vodafone de 5g only Telekom and I am planning to switch ROMs but waiting for a moment to unlock since I will lose all my data.

Yes but I'm in the States and no carrier supports the Mix 3 5g. What other ROMs are you waiting for to install?
Carrier Support Not needed for mi mix 3 5g
Dear slimegood,
I called my carrier and the result was that they communicated the values to connect to the 5g network to Xiaomi and they need to add it to their firmware. The problem being that some variants of the firmware have not picked up the configuration options.

Any luck? The phone does not support 5G out of the box. According to manufacturers website, "5G function will be available via OTA update. Update times depend on your specific carrier and network."
Let us know if you find a way to do it without the OTA update.

There should be a option under network settings. I it seems the development for this device is crap though (as far as the updates are concerned). It sucks it's on MIUI v10 which I understand why but they still should've had this figured out before releasing it.
Thanks.
Well thanks for the feedback, if the firmware gets released somebody let me know. I really like the phone, but compatibility with USA 5g is really important to me.
i dont think it will ever get 5g support in the states - it uses a different 5g tech than what the us telecoms are proceeding with as far as i was told.
Stating that - i use it on t-mobile and i get great 4g in most places.
