not sure about OP6 as it's a different brand all together.

As for getting poco modem.

if you adb shell into the device

and go to

/dev/block/platform/

you will see a file/folder called .sdhci

to get list of partitions we need to do

ls -l filenamewith.sdhci/by-name

example

ls -l 7824900.sdhci/by-name

this will give is partitions with name, then we can backup our partitions and also restore if needed.
[Xiaomi Poco F1 Questions & Answers] jondo24:
So I looked up a guide and it only mentions modemst1, modemst2, and fsg. Would fsg be the modem firmware? Or would it be something else?
[Xiaomi Poco F1 Questions & Answers] Heronicola:
Modemst1 and modemst2 are the actual efs partitions which have settings for the modem firmware. The modem firmware has its own large partition named "modem". fsg I've read is also part of the EFS partitions, but is used as a backup partition for modemst1 and modemst2.

I went and downloaded and unpacked a bunch of MI MIX 2. I found a modem.img in:

MI MIX 2S Global_8.8.28 ROM:

http://bigota.d.miui.com/8.8.28/miui_MIMIX2SGlobal_8.8.28_0f28e75344_9.0.zip
[Xiaomi Poco F1 Questions & Answers] Heronicola:
I flashed the Mi MIX 2S modem and then the modem + boot image individually. I observed no change in band recognition with the modem and default POCO boot image, and then no changes in band recognition as well as a lack of WiFi support when I flash the MIX modem and boot images. This is the same result that I received when attempting the same process with the Mi8 modem and boot images.

However, the EFS partitions remained the same since we do not have a copy available yet. A copy from a MIX, Mi8, or OnePlus will hopefully be the needle in the heystack.
[Xiaomi Poco F1 Questions & Answers] jondo24:
Hey so just an update, his bootloader hasn't been unlocked yet so we have to wait for that to happen in order to back up the efs partitions.

[Xiaomi Poco F1 Questions & Answers] jondo24:
So my roommate isn't too happy about the whole wiping data part of unlocking the bootloader. Is there a way to unlock without wiping data? Or is this inevitable. I know that the xiaomi a1 is able to using adb commands. I wonder if there is a similar way for the mi mix 2s?
[Xiaomi Poco F1 Questions & Answers] Heronicola:
To my knowledge, the wiping is built into the firmware as a security feature, and the mi a1 had a bug where the unlock could occur without the wipe. This behavior would theoretically be patchable if the bootloader were flashable, but the flashing feature is locked to begin with (hence the locked bootloader). Wiping the data is probably going to be necessary. There may still be bugs which allow another mi a1 unlock to work, however I am not aware of any such bugs on the mix 2s.
[Xiaomi Poco F1 Questions & Answers] munchy_cool:

The only idea I have in mind would be to try this version of Mi Unlock if you have not already https://www.mediafire.com/file/ykvjawchrhtekwc/MiFlashUnlock_3.3.525.23.zip, as it worked for me on the Pocophone. Versions released more recently gave me account errors as well.

I will be unlocking the bootloader on the MIX 2s as well, so hopefully I can come back with some insight if the error remains unsolved by then.

Based on the thread's OP's attitude and focus, I derived that he/she is demanding attention over the rant about how we did not "find out" in time and his/her misinformed purchase. There is no actual content in that thread besides random claims and quite a bit of anger. The image is what you get when you open up QXDM and select the LTE tab in NV Browser, which does not show us anything besides what QXDM looks like when you first open it up. If savorymilkman is reading this, prove me wrong. I am open to having what I said be completely false. I just cannot determine much, if anything about that thread without the work written down. When determining what may have been done by factoring in the language and attitude used, my hopes turn pessimistic.

And yeah his picture evidence didn't seem that compelling to me. I'm curious as to every step he did take and what he has attemped though, maybe we could learn something?

Would be nice to know if the pissed off guy who used QPST had tried this guide to unlock bands: https://xdaforums.com/showpost.php?p=56577252&postcount=455 obviously needs to be rooted and bootloader unlocked...
[Xiaomi Poco F1 Questions & Answers] pringlet:
I don't know about the pissed off guy in that thread, but I tried unlocking the bands multiple times following that guide you linked to and other guides using QPST and QXDM using the NV Editor. If you go back through this thread, another user on here also attempted this. All attempts to unlock additional bands through QXDM have failed. It appears they are locked some other way, potentially in the modem software.

So apparently the product manager of Pocophone even posted a comment on Reddit warning US users to not buy the phone because it probably wouldn't be compatible.

I guess that says it all :(.
[Xiaomi Poco F1 Questions & Answers] jondo24:
I feel like that's just implied by the official bands supported. It doesn't make sense that they would say that then release the phone in Mexico which also uses bands 2 and 4 for lte...
[Xiaomi Poco F1 Questions & Answers] adibeckett:
Is Mexico getting a different global version from everyone else? Maybe they use bands 5 and 7 over there.
[Xiaomi Poco F1 Questions & Answers] jondo24:
I believe they have the same global version. And no, they use bands 2 and 4 in Mexico https://www.frequencycheck.com/countries/mexico

[Xiaomi Poco F1 Questions & Answers] dindu11:
Guys, I was looking at pocophone reviews on Amazon Mexico, and it's a mixed bag.

One Telcel user has screenshots of LTE reception on Telcel

. However there are some indeed who're complaining of no LTE reception.

One interesting reply to a review I saw:

Marcelo Salgado4 days ago

I commented the SIM slot has 2 Slots to work in 4G well you have to do the following: You have to put the SIM in the SIM1 slot, if you put it in SIM 2 it will not work, unless you enter the configuration of SIM and activate the option to use 4G in both SIM slots. If you do not do this and put the SIM in slot 2, it WILL NOT WORK YOU IN 4G. regards

Can anyone please confirm if they try with Sim in slot 1 does it work?

Mexico has LTE bands 2 and 4, and Xiaomi hasn't released a separate Mexico version, only the Global. So it's baffling how they're able to get LTE at all.
[Xiaomi Poco F1 Questions & Answers] pringlet:
I tried multiple SIMs in both slots. I tried 2 AT&T SIMs as well as a Mexico Telcel SIM. I even reset multiple times and set my region to Mexico. (Note: I was not physically in Mexico) No LTE for me. Using Signal Guru, band 2 and 4 never showed up.

[pt]
[Xiaomi Poco F1 Questions & Answers] dindu11:
I guess Mexico hasn't had an official release yet. And upon further research apparently Telcel has Band 7 in some cities which might explain the LTE reception. :eek:

I highly doubt Xiaomi will exclude these bands when they officially release it in Mexico. The other two major carriers ATT, Movistar are on Band 4 and 2 respectively.

Anyone with Twatter care to ask Jai Mani when they anticipate a Mexico release? I don't have Twatter :crying:

just received my poco and it show 4g on tmobile network ( i'm living in california san jose ) . i'm not sure it is Lte or not i ran speed test app and it show 3g 3mb down and 1.5 up . i use Lte discover app and it show hspa+ it doesn't show what band i'm using tho, but i got LTE on my Zuk z2 plus so i guess no LTE for me

Flash these partitions from other device will brick it
[Xiaomi Poco F1 Questions & Answers] munchy_cool:
source of information?

please dont make claims without backing it up with information. we are trying to flash partitions from a very similar device and hence Mi8 was chosen. It's not that we are cross flashing among oems.
[Xiaomi Poco F1 Questions & Answers] tmacfeng:
I want to get band39 on poco f1...
[Xiaomi Poco F1 Questions & Answers] SubwayChamp:
I would can to put you here more than a 100 of links for reference, the rule number one about flashing is not to flash ANY partition file from other device, no matter if it is from the same OEM at all.

Time ago I bricked my device for an enthusiast guy that uploaded a rom with a file inside from other extremely very similar device and from the same OEM in an unrecoverable way, it´s permanent bricked and the file not even was a modem or an efs partitions (most sensitive) but a file of a few kbs.

Sorry if this discourage someone but first the truth and some not advanced users need to know this.

I don´t state, I can´t sure you that this definitely or without a doubt brick your device but it is a high risk to do it and this warning is something the users need to know, is their right.

If you want to do this is so simple like download a rom from Mi8 and flash this partition replacing them inside your rom, use MiFlashTool or if you prefer throug EDL mode.
[Xiaomi Poco F1 Questions & Answers] munchy_cool:
Thanks for your concern. We already know advanced users need to do this hence there are no instructions in the OP on how to flash the partitions.

Your first rule might be applicable for cross flashing partitions from different OEMs.

Go to the Mi A2 forum and check if they can convert a Mi A2 to Mi 6x and you will be surprised that you can.

As for your device getting bricked, sorry about that and I wont comment on that until I have full details.

As for users knowing, again we are NOT asking anyone to flash anything. There are no instructions on how to flash the partitions and there are no files to flash.

Thanks for your concern.
[Xiaomi Poco F1 Questions & Answers] SubwayChamp:
I´m not agreed that it is sure to flash a partition from the same OEM no matter if it is from a different device according you but It´s ok; it´s your opinion, anyway anyone that read this is advertised, just a last comment; Mi A2 is exactly the same device than Mi 6X with the only difference that Mi A2 come with Android One and Mi 6X with the usual MiuiOs.

Regards.
[Xiaomi Poco F1 Questions & Answers] munchy_cool:
like I said, there are no instructions in the post on how to flash partitions and no files.

Also, how did someone know that Mi A2 and Mi 6x were same? someone took the risk and tried it, right? or did Xiaomi come and tell everyone?

we are not asking anyone to take the risk. when we do it will be mentioned. You are on xda developers, and everyone knows that flashing a device can result in a brick.

Like I said before, thanks for your concern and warning.

While in the subject of band modding, how do you enable Carrier aggregation on the already working bands?
[Xiaomi Poco F1 Questions & Answers] Heronicola:
The goal with the MIX 2S dumps was to flash the partitions directly onto the Pocophone via DD. IMEI and WiFi MAC Address were hopefully removed from those backups. The behavior that could result from such an operation is unknown in this instance, and anything could happen. At the very least, IMEI will need to be swapped to the IMEI of the Pocophone of whatever user is attempting this mod. [MENTION=5415319]villahed94[/MENTION] can you tell the original provider of the firmware to replace the IMEI with a placeholder such as 000000000000000 or aaaaaaaaaaaaaaa and then tell us the placeholder? This would allow us to pinpoint what we need to change in the EFS dump.
