Help unlock enable carrier agrégation - Xiaomi Mi 8 Questions & Answers

hi friends mi 8 is not compatible b3 + b20 and b7 + b20 for the advanced lte.
who could try to unlock.
thank you

Hi,
I'm currently really interested too.
But I'm afraid there is no possibility to do it.
I'm no expert so I hope I'm wrong.
Will follow this thread anyway.
Thanks for pointing that.

it's possible to do it with QPST and QXDM.
on xiaomi redmi note 5 they did it. if necessary I provide the QCN file

Adding b20 to mi 8 SE

Hi,
can someone will try to add the band b20 (and maybe b28) as it seems there is no global version with b20 ? It could be so cool !

Possible to reveal missing basebands?

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 can't
Is there a way to get bands 2 and 17?
i think nobody can help us u.u
You guys can wait for the QPST for SD855 and hold on to your phones until then... I'm quite also waiting for this tool to unlock B20 baseband.

Question Switching to global rom - modem files

Hello everyone,
Searched the forums and could not find a definitive info regarding this, apologize in advance if i missed it.
I'm soon to receive my mi 11 ultra china version.
Alltough the bands used by all the carriers in my country are all supported, i've read somewhere on the mi 11 forum that the modem settings for china are different from the global/eu rom ( at least for the mi 11 ).
Wanted to know if i flash the original global/eea rom from xiaomi via the official tool, will i also get the modem configuration from the global/eea rom ? ( Just like the global mi 11 ultra )
Cheers !

i think you can BUT, don NOT lock the BL when you have a cn version running global or EEA.
As far as i know you can flash other versions as long as you keep BL unlocked, or it wil brick and you need EDL

You can unbrick now without edl iirc
There is a method on YouTube but I haven't needed to try it yet
When you down load the ZIP document with ROM every week, boot (kernel) & device ... Some instances it is also called modem or baseband (no idea what is the right ... I have Mi4w with miui7 ultimate international builders model.

If you mean the modem configuration like unlock needed bands it won't work.
I am not sure, but I guess it can be done. As far as I know, you can flash other versions after you keep the BL unlocked, I hope it works for you.
I'm on a china model in the US with the global rom installed...I would love to be able to use 5g. I would have to believe that if the hardware supports 5G and the modem software is preventing it there must be a way to get it to work.

Are you on global or EU? I bet if you switch back to Chinese, you'll have it working.

i'm on global. i bet you are correct about switching back to the china version...that's why i am thinking it is a software issue which like the OP I am hoping someone can resolve.

This is an older thread but wondering (1) did the baseband change to global after flashing the global rom? (2) Did it then pick up the band 66 (IF broadcast by your carrier in your area...not necessarily everywhere) Thanks
edit...folks are imo incorrectly focused on 5g (getting 5g or not) as its deployment is very spotty. Further if you check via signal check lite or Lte discovery apps, you will see that even if the phone shows 5G in status bar (lots of folks say they 'get' 5g based on that) the actual band is an LTE band usually (this is even with Apple iphones-have tested them out both on Tmobile and AT&T in my area...the 5G is mostly bunk imo and just marketing). ANyway, I digress. Does the flashing of global rom change the baseband to the global baseband and is the phone then able to pick up LTE 66 IF broadcast in your area?
