Rooting/flashing on Redmi 3s International Version (w/ LTE Band 20 800MHz) - Xiaomi Redmi 3s Questions & Answers

Hi you guys,
I've been reading here for a while, using my Sony Xperia X8, HTC One S, HTC One M8 and now I got a Xiaomi Redmi 3s Prime, but the version with LTE Band 20.
I haven't found any special Guides for this version and I am just curious, if there is there is anything I have to consider before rooting and flashing any custom roms.
For example, will my Band 20 LTE still work?
I bought my phone on HonorBuy, Model No. 2016031
I would post a URL, but I can't as I'm newly registered, just search "redmi 3s international" that should do the trick.
Oh and I already got my confirmation to unlock my bootloader, so on that side won't be any problems.
So long, thanks in advance for any help

Make sure you tick the "Allow OEM unlock" in Developer Settings and normally after getting the Unlock Permissions from Xiaomi, quite a lot of people had to wait for 5 days to a week for the unlock info to sync to the respective servers. The delay may or may not happen, so give the unlock tool a try. That's it.
One more thing, just to be safe, download the Mi Flash tool and the latest stable global fastboot ROM.
Good luck.

Thanks for the answer!
I have unlocked and rooted the device now, everything works fine
I'll still wait with flashing a custom Rom, is there anyone who knows, if a rom for the "normal" 3s will let me use Band 20 LTE or if there will be any problems?

I have a 3s with 20 lte band and there are no software differences between others 3s. I use same rom (xiaomi.eu one) than other 3s.

Baseband change when updating to Official stable or developers rom

Been looking around trying to find info on this in the xda and Xiaomi forums. Don't want to bork my device...
Received a new Redmi Pro Prime that I purchased from Xiaomi Mi Store online a few days ago. Still waiting for permission to unlock as I want to install TWRP, root and Xiaomi.eu rom(8.1), but thats another issue. My question is this.
New Phone came with Android version 6.0 MRA58K shop rom: MIUI Global 8.0 | Stable 8.0.4.0(LKXCNMA) with baseband MOLY.LR11.W1603.MD.MP.V13.18.P27. This phone is suppost to support LTE FDD-LTE B1:2100/B3:1800/ B5:850/B7:2600/ B8:900 acording to Xiaomi Mi Store (tested and confirmed working). I need B5 and B8 for my location in Canada.
Would updating the phone to the Official China Stable V8.1.2.0.MHQCNDI (MIUI8), or Developers Rom 7.3.16 (MIUI8), result in the new rom changing or overwriting the baseband, possibly removing LTE B5 and B8 from the supported LTE channels ??? Not sure if the LTE bands are locked/hardcoded into the modem/radios or if a new rom with baseband update will screw with supported LTE channels.
Second question: Is there a way to preserve the baseband without bootloader unlock or root ??
anyone able to point me in the right direction to information ??
Thanks
Hi,
Flashing Official, Unofficial (Custom) ROMs will not change your basebands in any way.
The global edition of the Redmi Pro has full LTE band support.

OnePlus 5 A5000

Hey guys,
I am planning to buy a OnePlus 5 from WondaMobile and they sell the A5000 model. Is that a chinese version ?
They also say in the website that they will install the OxygenOS ROM, will it cause any problems and finally is it compatible with all the customs ROMS and TWRP ?
Thanks in advance
EDIT : Got the answer by searching, sorry for the thread
I've got a OnePlus5 N.America and it's a A5000
Apparently there is only one model.
Bands are determined with software - the region rom you flash on setup (it's automatic) determines what software and bands are active.

FDD-LTE by ROM?

So does it matter if I grab any Mi Note 2 and just install the global rom? Meaning that I grab the local and install the Global rom that it will work in the US on LTE? Thanks.
It's a confusing way they've named things but no.
Global rom and global edition are very different things.
The Global rom will run on all editions of the phone and includes Google apps.
The Global edition will run either Global or CN rom and has many more bands available for use.
Changing the ROM will not change the bands that the phone is capable of.

It's a hardware issue, not software.
Just wanted to be sure. I know that there are ways to open up LTE Bands on Snapdragon CPU, but don't know how easy or hard of is

I am not going to dissuade you from trying but I wouldn't try opening that can of worms and just get one of the newer Xiaomis that have global band support out of the box like the Mi Mix 2 or the Mi A1 (check the specs for both devices on gsmarena).
Mi A1

I am trying to find hard specifics on the Mi A1, as far as US Bands. We are about to get the Mi Note 2 Global, but my gawd is it hard to get Global ROMs from the Chinese sites. They can't seem to get shipments in and it's wait, wait, wait....
Been looking on the web for Mi A1 bands and I am under the impression it won't have several bands needed for Verizon/TMBL/AT&T....

LTE Band Xiaomi Mi Note2

Hi, I'm new here. I have a question. is it possible to unlock b20 band on Xiaomi mi note 2? In Poland I need to use LTE 800 Mhz. I apologize for any mistakes but my English is not very good.
There are some ways on the internet for different Snapdragon devices and CPUs .
Never heard any Mi Note 2 user that he succeded doing such operation...
I guess you don't have the global version and need band 20 for LTE...
Maybe someone will come with a different and better answer, but as i know, you can unlock them in software but hardware does not support those additional bands that the Global version come with...
I tried to change the nvram parameters but to no avail

Bro follow me guidelines

Can we flash global rom on chinnese version?

My question isnt about language is about the band frecuency global version can support.
Or we can have issues with antirollback? And need to have unlocked bootloader.
Maybe even with bootloader unlocked bands will not be abailable.
Thanks for reading

The global version of the Redmi K20 as the Xiaomi Mi 9T will be on sale on Monday, June 17th with the 6GB/64GB version on sale for 299 Euros for that day only while supplies last. Phones come down in price after 2-3 months. Bands are shown here under Specs https://www.mi.com/global/mi-9-t/specs/
You need to unlock bootloader first then can flash to any firmware Global EU RU, but this will not give you band support. bands are hardware thing.
