Where did you buy it? On aliex there are two "global" phones. One is "global rom" version which does not have B20 support (it is actually a chinese version with global rom pre-installed by the seller), and the other is "global version" of the phone which supports B20.
Search on the forum, there were attempts of unlocking B20.

I buy it on Amazon

Check on the box to see if it supports B20

Because a someone write in comment that he hasn't b20, but this after that i buy it.
On Amazon they just write global.... it Comes from Germany...
It comes tomorow to my Home, and i really hope that i have this b20, otherwise i'm f****d
In case of that i don't have this b20, is there a way to unlock it?

So you don't even have the phone yet and you are complaining about it not having B20.... smh. Nice one :good::silly:

Sorry your question ist very silly...
Global Version has band 20. In Germany band 20 is the Most used on. If you bought it from Amazon Germany you have band 20. If Not you can send it Back.
An No, its not unlockable. Maybe we can Help you to unlock your VW Polo to Porsche gt?!

A question is always silly when you know the answer. I didn't know that band 20 is the most used in Germany, like in France!
And why do you talk about polo and Porsche ? I didn't ask to boost the phone performances. If i want a "Porsche", than i just buy one! I know that i didn't buy one.

You can lock or delete this post if you want

Same situation here. I bought a Xiaomi Redmi note 7 pro, and it doesn't have the B20 band. My fault.
Some hope I can solve it with a software-based solution (e.g. installing an app, or flashing a custom ROM without a Windows PC) or it is really an hardware based problem ?

Unlock FDD LTE Band 20 on OnePlus 2?

Hello,
I received my Oneplus 2 today and it does not support the LTE Band 20. It`s the chinese Version and i would like to ask if anyone figured out a method to unlock the LTE Band 20. It`s because the Hardware of the Oneplus Chinese version is the same like the European version.

Sounds like the OPO all over again. Remember seeing varying reports of success with that.

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.

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.

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.

LeEco Le Pro3 X728

Hi,
yesterday I got my new 4GB/64GB Pro3.
Surprisingly it's branded Lex728 instead of Lex720.
Does anybody know the difference?
More important: Is it SW compatible (Rom/TWRP) to X720?
EUI seems newish: 5.9.020S
Greetings

Hi mike. I think its compatible. Look at the rom of tora at leeco.ru forums. Its compatible with the x720,x727 and x728. I bought one of this but it didnt arrive. I think one more week to arrive.
Enviado desde mi XT1635-02 mediante Tapatalk
I'm interested in the differences between x720 and x728 though. I can't find relevant informations anywhere...
Is the same as x720 but not Lte Band 20
LTE Bands 1/2/3/4/5/7/8/12/17/29/30/38
Hi,
that would be really bad!
Any chance to switch band20 on using a (Qualcom) tool?
I had a qick look using CPU-X and found no differences to X720 so far.

Looking with Network Signal Guru from Playstore.You can see had Band 20 or not.But you must be a rooted Phone
No B20, that sucks. And for the same price as a x720 I imagine...
Hi,
today I tried with a LTE-enabled SIM,
and network signal guru showed the use of Band20 ?!?
If it can use Band20, whats the real difference to Lex720 then?
Sent from my Elephone P8000 using XDA Free mobile app
I have this phone since yesterday.
The real bands of the phone are LTE 1, 3, 7.
I flashed other roms like Grossoshop, Tora, Turbo and in the signal guru app appear all the bands, like 4, 20, etc.
The problem is im in a country with band 4 and the phone never worked with LTE. Only 3G.
I think this phone didnt have the hardware for work in LTE 4, 20, etc.
If you will buy a lepro3 buy x727, x720 or x722. Never x728
It could be modem matter. Maybe changing the modem (it's a software driver) with one that will enable band 4 (from Lex 720 or 727) you might solve the problem. Try asking an experienced developer, I think it can help you easily!

I tried that. With x727 modem--- no simcard detected.
With x720 modem---simcard detected but only 3G.
I think its more that a hardware limitation.
So does it have band 20 or not...
It is currently sold on banggood (x728 version) and they say it has band20 and all the bands x720 has. Does ROMs for x720 work on x728 ?
Roms for Lex 720 are working for Lex 727 and 728 (same hardware). If something related to specific model is not working as you expected (2 sim support or band/modem related) is to see case by case and (perhaps) there is a solution searching in this forum. Cheeers!

AL-20 vs TL-20 "China Mobile"

Hi,
I am about to buy Huawei Nova, directly from China, and I've found that many sellers offer "AL-20" and "TL-20" versions, where the second has the "China Mobile" printed on the back of the phone. Is it truly the only difference? Sellers say they both have CAN-L12 firmware.

Can you provide the link? Is it through Aliexpress? I'm pretty sure that apart from the logo there's another difference, and most probably it's a frequency band. TL version might offer you the B7 band (4G) , whilst AL not - instead it has B5 incorporated - which is not used at all in some countries.
Also, you should check the duplex, Tdd or Fdd. I believe that Fdd is a more European standard, at least here in Spain it is.
Additionally, TL is also a bit more expensive.
But please, share the link first, to be sure that it's that.

This is the wrong forum as al20 and tl20 are Nova 2 models. To answer, the tl model is specifically for China Mobile whereas the al model is for all three major China carriers (China Mobile, China Unicom, and China Telecom). AL has more radio bands than TL.
Same issue

Flash IN2020 to IN2025

Do we have a clear, step by step on how to do this? I've tried flashing the IN2025 firmware via local update but it still shows as In2020 with disabled camera.
Might want to back up your persist partition before you do that. May break it

Well yes, but I'm trying to get it to flash to IN2025. It's just not doing it.
Flashing software does not change the hardware. You're on an IN2020, and OOS will report as such even when you flash intl OOS.
So essentially, there's no way to get it to re-enable the IR camera.

If the phone does not support your radio bands, changing the firmware to the unlocked Global FW won't enable them.
If your carriers radio bands are supported by the IN2020, you may need to add their band combos as per this guide:

He hasn't changed the hardware, he has changed code to trick the phone to get the photochrom filter back, this will not work on band's for 5G
i have a Photochrome option when i use my camera, does that mean that it's still in though.

Yes if the option is there you will have either a phone that isn't IN2020 or 21 or if you do you have one of those phones you aren't running the latest firmwar for that phone.
Where To Get This Model EDL Mode Firmware , One Plus 8 Pro China (IN2020)
My understanding of 5G support by these different phones is in the link here, https://drive.google.com/file/d/1mgz7Z6TADnXZgpCdCoLeRHX22wC_vLq8/view?usp=sharing . I am currently in the U.S. and a T-Mobile customer but planning to move to Europe one of these days. Though T-Mobile only supports the n71 band today (not supported by IN2020), it will be rolling out the n41 band (supported by IN2020) soon with the merger of Sprint. On the other hand, n78 (supported by IN2020) is quite common throughout Europe. With that said, the Chinese Model, IN2020, seems to be the best compromise if one travels extensively. It overlaps with the European bands over several different frequencies and one US band that I know of (n41).
Unless of course you are an AT&T customer, then IN2025 is the only way to go because they use n5. In this case, you won't get 5G coverage while you are traveling internationally (except on n41 in China) because the US 5G is just so different than overseas.
None of these models support mmWave, and these phones will become antiques first before mmWave is ubiquitous anyway. If even fingers can attenuate the mmWave signal, we are talking about at least several transmitters on every city block to make it practical! That said as of 2020, I wouldn't spend extra $150-200 USD for a phone that supports mmWave. Google's new Pixel 5 could have been $150 cheaper without it.
Other than the radio compatibility, I can't really think of a good reason to convert an IN2020 to IN2025. If I'm missing something, please enlighten me.
The method described by Whoareyou sounds very interesting. I may try that one of these days.

Here's my story.
I got my OP8pro in China, and once it's in my hand I flashed it from H2 OS to Oxygen OS. Through the past two years my model was showing as IN2020 with no issues until I saw a Beta version of Android 12 Oxygen OS. I flashed it and the model turned to IN2025...I googled the difference and that's how I get here.
