Band 17 support?

So I was about to buy the phone but wanted to verify LTE bands first. The seller lists B17 support, but the Mi9 web page at Xiaomi's site does NOT list band 17 support. I find this strange, since the Mi8 does support B17 and the Mi Mix 3S supports B17. So Is there any real confirmation on whether the Mi 9 does or does not support this LTE band? Is the lack of it being listed at Xiaomi site just a type?

So does that mean only Chinese versions support this and I must buy Chinese version and run Chinese ROM to get band 17 support to work with ATT? I would rather flash to Global ROM, but I am thinking that Global kernel or other firmware may remove B17 support? Can the Global ROM be run on China firmware? They do say China ROM support English....

I'd definitely trust Xiaomi's official site more than anywhere else, if you check Xiaomi's official site for Spain (which sells the Global variant) it doesn't list band 17..
Flashing Global on a Chinese device or vice versa doesn't affect the bands as far as I'm aware, there's evidence of Xiaomi hardware locking the bands on the Pocophone, forum links below:

https://forum.xda-developers.com/poco-f1/how-to/pocophone-lte-band-unlock-report-t3848193
If you buy a Chinese Mi 9 then you should be able to flash the Global ROM, same as all previous Xiaomi's, however you have to keep the bootloader unlocked once flashed, trying to relock will result in a brick

These steps were for a MI Note, but may work with the MI 9:

Thanks for the reply. I ended up buying the chinese version phone just now since that is the one Xiaomi says supports the bands I need. I will work on it when I get the phone in and verify whether I can unlock and install global ROM and still have the bands :good:
Thank you for your help

I'm seeing some contrary information out there about what phone has what bands. Is there a code I can enter in dialer to see all available bands on my device? All I see is that I'm currently connected with B2 in *#*#4636#*#* and various apps I've picked up. I'm wanting to see exactly what's available in the device in my hand rather than specs on 4 different websites(with different values). The primary website I'm looking at is showing me I made a mistake with getting the 8/256 transparent china rather than the 12/256 but I'd really like to know for sure(especially since I'm currently not experiencing any problems with AT&T). It was easy with my W10M phone(##2382#) but I'm a bit lost with Android.

Unfortunately for me it didn't work. Like I said, 4G + appears on my phone screen, but the apps don't connect and I can't even use the browser because it says I'm not connected. Already tried to fix APN settings, checked if I had LTE on, but nothing worked. The internet only works if I have H+ on the screen. And now I have another problem: I downloaded my original parameters before switching to the modified ones, but now when resetting my original parameters and restarting, the phone remains without a network signal. The IMEI numbers are correct, the settings are ok, but I still have no network signal. Does anyone know how to fix this, or have the original .xqcn file to send me? Thanks.

are you posting in the wrong thread? there are no instructions in this thread.

Will the K20 Pro being sold on Flipkart tomorrow be the chinese model?

I'm very confused.
Flipkart are selling K20 Pros in a flash sale tomorrow. Are these the same as the ones sold on other websites?
I read somewhere that Indian K20 Pros will have a different devie codename and take different ROMs. Some people say they won't have NFC, and others say it's a software limitation.

Any model sold in India via official partners like Mi.com/Flipkart will be the Indian Model codename Raphaelin. NFC is not of much use currently in India and its forced disabled from the software at the time being on 10.3.3.0 Future OTA's might trigger and activate it but no one knows that for sure as there was no mention of NFC during the launch, however users who have unlocked and flashed EU roms have NFC enabled so the hardware is definitely present.
The Chinese variant is not sold here and the code name is Raphael.
You may visit this thread running to mention the existing issues users have reported.

Thanks, so just to confirm, I can flash raphael ROMs (and it'll change to Raphael in the build.prop) but I'll loose Widevine L1?

Also, are the radio bands the same?

Yes, but you'll need to flash a fastboot ROM with the Mi Flash Tool.
You'll lose Widevine L1 and gain NFC.

Not quite, the Chinese model appears to have a couple of extra bands available (comparing specs on the official Indian and Chinese Xiaomi websites).

Flashing different region stock from 960N (Korea) to 960F (Asia)

The specs for both models are same including CPU but 960F (Asia) support DUAL sim whereas Korea only SINGLE sim.
If I odin 960F to my Korea model phone, will it still work? or probably freeze on E.g. Settings when I click Sim 2?
How about the Samsung Pay?
If firmware 960F can work, can I use Samsung Pay in Asia? or they are some in-built mechanism E.g. Knox that will prevent this?

Same question. I have a SCV38 - Japanese KDI/AU Galaxy S9. I have only Android 9, but there are a bunch of US Snapdragon Galaxy S9 based on Android 10. Can I flash this (US firm on JP phone)? I just want to get to Android 10. I have a feeling that wont work, and I checked for the S8 - US and JP phones, altough based on QC chipset had other hardware differences...
Anyway, appreciate any advice on the matter.

As long as the specs are the same you can flash any region rom. You will just have to try it yourself and see if both sims work. Google pay shouldn't have any problems. The only problem you might have is some roms have different baseband files so you might not get network connection if it's not right for your region.

Make sure in download mode you don't have RMM prenormal if you flash Android 10 and it's prenormal you will never be able to get rid of it.

[Q] CN to WW

What's the current status on XDA re. CN to WW conversion guides?
Is CN to WW conversion possible for ROG 3? If so how? Is such guide allowed on XDA forum? (previous topics on this subject seem to have links deleted etc)
I am seeking to root ROG 3 & have custom kernel/ custom ROM installed when available - can I do this on CN variant?
Pros/ cons of CN vs WW variants besides Playstore/ GPay/ chinese vs google bloatware etc?

Any takers re. above questions?
If CN to WW conversion is truly possible; does this change the network band coverage in any way?

Asus has said that it is possible to flash the WW firmware onto CN phones, but you will have certificate issues apparently. However my concern is on the radio. Does the CN version have the "Version A" radio or the "Version B" one? The latter is undesirable especially if you're from the Americas since it lacks the 700MHz bands that the continent uses.

I converted and all fine and all work.

Change from G7810 to G781B Please help me

Hi, I wonder if it's possible to convert Hong Kong variant of S20 FE 5G (SM-G7810) to European version (SM-G781B). What I have to do?
Please help me!

it is impossible to do

I am interested too, since I bought a SM-G780 model, which will be delivered to me in the next few days and I would like to carry out the same operation, I have already downloaded the Italian CSC ITV firmware SM-G781B; through Odin, can it be done? The phones have the same features, same processor, change the RAM which in the SM-G780 is 8GB, while in the SM-G781B it is 6GB. Thanks.

do not give people false hope, this method will not work.

Voice HD+ (EVS full band 128kbit/s) you only need to correct the configuration a little.
And flash G7810 to G781B - not possible!

I still have to receive the smartphone, I found the difference between the G7810 and G781global on this forum.
So what are the substantial differences then? And is it possible to put a Firmware / Global Rom while keeping the original phone, that is, without root and with OTAs?

I don't understand what you are trying to say.
First you pasted some screenshot without showing second one for global version (for which rom is it?)
Once you say it will work then you say it won't
As to WiFi calling I am using it all the time at home with Chinese version.

Perfect. While the Google PlayStore, and other services work? There are no problems or report at the software level I mean!
Because for my country Italy, the frequencies of use of the G7810 are fine! So I was more interested in removal or software related problems!
Thanks a lot for the answer

its not posibil to do that and you dont need to do it you will get the update later in february.

Today arrived my 7810. As I need to be avle to use phone-recording I always did the CSC-trick trouwgh the THL-roms on S8, S9, S10 etc.
Therefore I am curious if there is a way to make phone recording work native as described above, or through app as ACR-call recorder on THY ( Hongkong-ROM).
For hardware the difference between 781B ( Global) & 7810 (Hongkong & China) is 6 GB vs 8GB.
That's probably why people think it is possible to flash other ROM into 7810 .

First have you forgotten the fack this is an international forum, where english isnt for a lot of people tghier first language. And secondly being insulting helps no one.
If you can a technical reason as to why the OP can't just flash a G781B stock rom to his G7810 device, that would more productive. Will it for example just not work and soft-brick his device requiring flashing back to G7810 firmware etc..?

Ofcourse I'm not sure about HIS, but MINE is also a 7810 Hong Kong version with 8 GB.
ALL European sold S20 FE 5G are 6 GB.

So what are the software differences within the sm-g7810 and the sm-g781B because i want to buy this phone too.

I'm thinking of buying the hongkong version from Canada. The process of unlocking the bootloader and rooting will be easier in this version right? Will the custom ROMs be compatible with the 8 GB hongkong version?
Otherwise I will go with the Canadian version.
