Hi,
Can somebody help me?
I have a question.
Is the LTE B20/B17 difference in hardware or software?
If I buy one Mi 9 Chinese version phone and than I put the phone a Global ROM the B20 frekvency is will working?
Sorry for my poor English.

no - just no.
its not a software unlock, frequencies were locked in hardware.
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?
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.
isn't mi 9 using the same modem (x24)? Perhaps we can use its baseband

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.
Sounds not promising
Hopefully we'll find something anyway

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://forum.xda-developers.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.
Will this work? https://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774
No go for Band 20, but lots of people managed to unlock Band 4 in this thread. I'd love to hand band 4 on the K20 Pro.

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.

if it so, why does lineageOS for poco unlock all possible bands ?

I doubt that is true. Bands have nothing to do with the ROM

I saw a post on how to Flash stock rom on Oppo Reno 10x Zoom (Snapdragon 855) using QPST_2.7.460, is that the needed tool for band unlock?

Really? I have sold my f1 several months ago due to bands lacking. So I don't pay continuous attention to poco. Please post a site address

"NOTE: This page is auto-generated for the Xiaomi Poco F1, based on the device’s information, located here. You can find similar instructions for every officially-supported device on this wiki."
That is, they are the specifications of the mobile phone, it does not mean that LineageOS activates all the bands.

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.
I guess if Mi9 has already, we'll find a way (eventually) to unlock the bands.
its must be a stuppid question, but what have we got to loose, right...
Did anyone tried Network Signal Guru ?
cheers
Does anyone have their hands on a device currently? If so, are you able to enter qualcomm diag by entering *#*#717717#*#* in keypad?

You will still have all bands but you will lose Widevine L1 --> L3.
Hi. I'm wondering is it possible to unlock 5G 2600MHz band(n38) in China model. I'm using SIM card in Poland and my operator(Plus) provide 5G only in 2600MHz frequency.
Is there someone who succesfully unlocked this band in Mi 11 or Mi 11 PRO? Maybe change ROM to xiaomi.eu unlock this band?
