Sorry to break your bubble, but every Android phone with USB-C can use these Display Link Adapters to get HDMI output. The thing with K20 AND Poco is that a display link adapter is necessary to get HDMI output, because these phones have USB C 2.1 and not USB C 3.0 (which is capable of directly outputting to HDMI).

Hi,

If you only root the phone and custom firmware has not been installed, do you still get OTA updates?

Thank you :)
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
As seems Xiaomi unfortunately decided not to bring the pro version to Europe (no mi 9t pro) I am wondering if it is possible to make the missing B20 available on the Redmi K20 pro.

I am guessing it is not hardware limitation, right?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] kumoilain:
It's maybe not hardware limited. But need the current Qualcomm QPST tool to configure LTE bands for 845 and later SOC 855.

The previous version QPST tool (can find in XDA)can only add bands for old SOCs like 820/835 etc.

Some newer QPST tool can be downloaded from other site, but need a available account to log in.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
isn't mi 9 using the same modem (x24)? Perhaps we can use its baseband
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] kumoilain:
Same hardware, different configuration file, maybe the baseband partition is strongly encrypted by Qualcomm.

I've tried to force flashing mi 8 firmware into poco f1 (same SOC, and f1 lacks some frequency bands), no baseband is added to poco f1.

So I guess, if users force flashing mi 9 firmware into k20pro, k20pro's baseband may not change.:rolleyes:
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
Sounds not promising :(

Hopefully we'll find something anyway
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] BCE111:
Started looking into this for the Redmi Note 7 Pro which as we know never had a global release. I live in the United States and need more bands to get decent coverage. Sounded complicated with the possibility of bricking the phone. I'll have to wait for the official global release if it does come. They didn't rule it out yet as they did before the Redmi Note 7 global version came out. These were some comments earlier on GSMArena about possible delays. https://xdaforums.com/k20-pro/how-to/redmi-k20-pro-xiaomi-mi-9t-pro-global-t3939580

Does not sound promising, indeed.

I really need B20 for Germany, so I am really thinking about getting the Lenovo Z6 instead. Yes I know, it has a small notch but I need a replacement. :)

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] majimbo:
If I remember correctly Xiaomi Mi Note has Snapdragon 810. To be functional in the Xiaomi K20 Pro we would need a version of QPST and QXDM updated and functional with SD 845 and 855, as the partner above said.

Maybe it will be possible soon, do not dismiss it. We must be optimists.

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Mattewsb:
I thought the same when I saw this info, but if you look further at other releases and ROMs for another device, you'll notice they are very careful with this info. You will notice too that it's many bands, but it's not all.

That's great news! I can almost definitively say that we'll be able to unlock at least some of the missing bands if Xiaomi did not incorporate anything that would automatically revert any changes made to NV items.

I'm in Australia and the phones working fine. B20 Is the only missing band that's needed here. But from my experience if I'm with Telstra I shouldn't need B20 at all. Would like to see a way to add it in the future though

I'm not familiar with the baseband firmware stuff - how likely is it, that when the Mi 9T Pro is released, we'll be able to flash its baseband firmware onto the K20 Pro?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Robbo.5000:
From what I've read elsewhere, when people have tried to do this with other phones, it appears to flash OK, but nothing changes.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] skleppo:
So it seems, can't find any 100% confirmations of this ever working. There are many topics on it though, but I haven't seen conclusive proof.

What a huge bummer, this is really the phone that checks all my boxes, and now because of something so basic as them not enabling a few LTE bands it might make it totally unworkable for me :( Oneplus has the right idea here, they enable pretty much every band, c'mon Xiaomi do it too!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] OMG|OTG|OTA:
Do you think the same obstacles concerning changing the baseband firmware would occur if simply flashing a K20 Pro device with an official Global ROM (related to the supposed/anticipated Mi 9T Pro release)?

An obviously quite so easy-to-carry-out experiment would be to flash a Redmi K20 device with the Mi 9T (official Global) ROM and see whether additional bands thereby are made available (given that one has access to the required resources). This could at least give us some kind of indication whether there is a chance this could be solved.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] skleppo:
I've been looking for exactly that, but haven't found anything yet. You'd need to flash the modem firm though, the ROM itself wouldn't be enough AFAIK.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
But to try it we have to wait for an official global rom/baseband firmware
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] skleppo:
They're talking about taking the Mi 9T modem firmware -> K20 (not the pro versions). That's something that can be done already, and the difference should be pretty much the same (same basebands on the K20 as the K20 pro). If that works, it stands to reason that Mi 9T pro -> K20 pro would work as well.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] OMG|OTG|OTA:
If this is true wouldn't this imply that if one would flash, e.g. the Redmi K20 with the official Global ROM of Mi 9T, additional bands (e.g. B20) won't yet be made available?

Correct me if I'm wrong but I doubt that SD855 has the same modem as SD730
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] OMG|OTG|OTA:
I agree with you on that, but that was neither ever [meant to be] my point. The idea was simply that if a Redmi K20 device is flashed with the (also available) official Global ROM of the Mi 9T and this results in the K20 getting more functional bands (e.g. B20), wouldn't this thereby imply that the ROM also has something to do with the baseband firmware?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Guido83:
Ah I see. Yes I agree this test might be helpful
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] OMG|OTG|OTA:

I think at least there was one guy on the K20/Mi 9T Forum that told he had flashed a K20 with the official Global ROM:

The analogy "Flashing a global rom will fix the missing/hidden/locked carrier bands" is the dumbest idea ever. There are people in Mi EU waiting for the sd855 band unlock tool, because flashing another rom doesn't involve unlocking all the SoC's telcom bands.

I can consider it quite fair to agree and settle with that. In the end it's merely a question of [ordinary but likewise inevitable] setbacks in the “learning curve” (seen from my own perspective). I suppose most of us have experienced something of the sort. In short: errare humanum est

to try to unlock bands someone would have to try QPST.

I tried it on the Poco F1 (same hardware as Mi 8) but couldnt read the necessary values. looks like Xiaomi disabled the bands from hardware.

Actually that graph is not detailed enough what it says is that vodafone uses 2100Mhz but it does not say if it's for 4G or 3G, assuming it's for 3G it shouldnt be a problem as the k20pro does support 2100 for 3g. i used https://play.google.com/store/apps/details?id=com.novvia.fispy to check what my current phone (oneplus 3t) is using for 4G on vodafone egypt and it says it's using band 3 1800Mhz which is supported aswell. I suggest you check for yourself aswell.

As I said before I compared the frequencies with the honor 8x to be sure as lots of my colleages have that one and have no problems with 4G on it. I ordered my k20 pro based on this info I will receive it next week if you can wait that long I can report back when I have it

Hi guys, here's my story and a little update.

I live in Germany and I don't need 4G / LTE. I use WiFi at home and at work, I don't need LTE on the Autobahn.

I didn't even have LTE in my data plan using LidlConnect which is in the Vodafone network.

I bought the K20pro mainly because I didn't need Band20.

However, now LidlConnect added LTE to my data package and I was very surprised to see the 4G icon on my K20pro. I analyzed the network connection with a cell info app and saw it is using Band 1 which should be 1700 MHz, right? So at least in Germany Vodafone uses Band 1 (and Band20 simultaneously, I believe) for 4G

The earliest reference to the Snapdragon 855 was on release 2.7.470 (08/18/2017):

Inside the QPST installation folder there is a Documents folder with a Readme.txt in it describing the changes for every release. Eric1084 was referring to a readme file from QPST 2.7.477. I can't post the links as I'm a new user but here it is: gist.github(.)com/DarkFlamex1/7464f77d9b55a3b63e07456a69ccc122

If you look at Change #4 of QPST 2.7.470 it states

4) Add Chip id of SDM855, SDM670 & SDC670.

which is what Eric1084 was referring to. Hopefully this means the latest QPST we currently have supports a snapdragon 855!
