Hi! Xiaomi redmi note 5 (china)

NV 06828(29) - 2070308978911

*00011110001000001000000010000000000011011111‬

Please Lte band 20. Thanks
[Redmi Note General] marpelo:
I've tested this on a china Redmi Note 8 and works!!!

I live in Argentina and I needed to unlock band 4, that is the most common here.

I've changed the NV 06828 and 06829 values like this:

the original value was 2070174236821, that is bands 1 3 5 8 34 38 39 40 and 41. I´ve modified the value for 687195291871, that is bands 1 2 3 4 5 7 8 20 38 and 40 and now the phone is conecting to the local LTE network.

The weird thing is when I open network signal guru I can only see the original bands, and it says I'm connected to band 5, which is impossible here in argentina, we have band 4. But the LTE conection is working full speed

thanks a lot
[Redmi Note General] busybox11:
Damnnn you successfully enabled additional bands ON RN8 ?

I'm trying to enable 700MHz (B28) with no success.

But the weird thing is that I should have the international variant with 700MHz enabled.

If you can provide me your QCN file, I'll be very happy !
[Redmi Note General] marpelo:
Band28 is not supported either in china and global version, see the attachment with the supported bands for RN8View attachment 5002953

Enviado desde mi Redmi Note 8 mediante Tapatalk
[Redmi Note General] busybox11:
This is only for Global and China variants, but there are two others : Indian and International (the one I use and which was principally in sale in Singapore).

International does support B28, so I sohould have it.

Also, RN8T has the exact same hardware as the RN8, ans it supports B28. So i'm sure @ 200% that there is a way to grab their (radio / modem / whatever you call it) config file and implement it to RN8.

___

EDIT : So, how did you unlocked those bands ? They weren't listed on the page too...

Do you use a dual SIM RN8 ? How did you *precisely* edited those values (eg. which software, what steps, such as checking the "Multi SIM" button...) ?
[Redmi Note General] Mariano.:
This may work to unlock LTE BAND 4 for a Xiaomi NOTE 8T EUROPE? Thanks.-
[Redmi Note General] D.Price:
doesnt work for ya
[Redmi Note General] busybox11:
Actually, band 4 is unlocked out of the box...
[Redmi Note General] Mariano.:
But my phone have 1/3/8/20/28/38/40 bands. My country, Argentina, uses the band 4.
[Redmi Note General] busybox11:
Well, those papers are not always true. Try to see the band you're using with NetMonster and if you're rooted, see what bands are unlocked with Network Signal Guru.
[Redmi Note General] Mariano.:
4G:

3G:

So, i have signal with 4G LTE but not with 3g and 2g. Can i use the phone perfectly with that band, or it may work bad?
[Redmi Note General] busybox11:
Of course you can!

As long as your carrier supports those bands, it will work.

(And the majority of 3G bands are nearly the same in all countries so that's not a big deal.)
[Redmi Note General] ntwrld:
it works thanks.

:good:

thank you. i am from india so adusted your solutions to my situation but it definitely works. thanks a lot. stay safe stay blessed.
[Redmi Note General] busybox11:
Oh wow!

How did you succeeded to to it with QXDM?

What bands did you unlocked in which phone?
[Redmi Note General] ntwrld:
yes with qxdm and unlocked lte band 1 and 8 in redmi mido
[Redmi Note General] JoelitoZV:
Isn't it safe just to replace the actual Baseband version for the Global Baseband version in order to get all those bands in the Global version?

Please, post the guide clean again!
[Redmi Note General] busybox11:
I don't really understand what you're telling us, can you precise your explanation please?
[Redmi Note General] JoelitoZV:
Unlocking 4G LTE bands by replacing baseband versions

Ok, what I'm trying to say (so that you understand) whether it is possible just to replace the phone modem (baseband) driver of a chinese or indian version for the working driver of the global version, not the whole ROM. For example, my model is Indian (MIUI 12.0.1.0 (QGGINXM)) with Baseband MOLY.LR13.R1.TC8.SP.V2.P40 (that's the modem). So, if I get the corresponding Baseband of the Global model and replace it for the one I have, should it work. My 4G LTE bands are: B1/B3/B5/B8/B40/B41 whereas the Global model are: B1/B2/B3/B4/B5/B7/B8/B20/B28/B38/B40. In my imagination it is like replacing a physical modem for another as we do with PC and laptops! That's what I have seen in a couple of Youtube tutorials.

I hope you can now understand what I mean (I desperately need to get B4 unlocked) ...
[Redmi Note General] busybox11:
Oh, yeah, I see.

Could you help me with that?

I have (probably) an International (sometimes recognized as Chinese) ginkgo variant with global rom.

I flashed the Chinese firmware earlier but it didn't changed my LTE bands.
[Redmi Note General] D.Price:
Just give up this idea, you have to "modify" your QC in order to activate missing bands, changing only a rom or a part wont unlock any band
[Redmi Note General] busybox11:
I know that.

The modem / firmware / EFS is responsible for this.

Can't figure out how to activate it tho.

Tried QPST / QXDM but it turns out it didn't changed anything.
[Redmi Note General] rav101:
Out of curiosity,

I'm wondering if this methodology would work for a Chinese Xiaomi Mi 10 Pro or Mi 10 Ultra to get 4g band 20 working? That's the only one missing that I would need (that's currently missing from the Chinese variant) to be fully working on my network providor.

I can see that this was originally posted in 2017 and that people are still using this in 2020 but on other devices. Wouldnt want to take that much of a leap in price if it definitely won't work.
[Redmi Note General] D.Price:
As it concerns QC SD, theorically yes
[Redmi Note General] 08sv80:
Hello everyone, I have AT&T Z999, I tried to change the bends to LTE 1, 3, 20. according to the instructions, I wrote the value in 06828 (lte_bc_config) according to the instruction 2061584826436, but I just don't have a network. the phone sees a SIM card, I can register an APN access point, but there is no network. tell me what can be done?
[Redmi Note General] D.Price:
Hope you've saved original one before modifying.

Only restore original file or modifying as original was can save you
[Redmi Note General] jcgarcia011:
unfortunately its not going to work. QXDM that is available for download is too old and unable to make changes on newer phones. I have a mi 10 pro and its giving me an error when I tried unlocking my bands.

Hi guys,

Someone tried to get able the B2 and B7 for LTE (4G) for a Redmi K60 (Chinese Version) (SD 8+ Gen1)?

I read all the thread but I dont see nothing about it.
[Redmi Note General] skezza:
I saw them too. Difficult to tell if they're actually of use though.
[Redmi Note General] blackysan:
i had the same info on my HK model Redmi NOTE 4G and China model Redmi NOTE 4G. my China model Redmi NOTE 4G's 06828 value was 1099511627781 (FDD-LTE band 1, 3, TDD-LTE 41), but interestingly, my HK model only shows 79 (FDD-LTE band 1, 2, 3, 4, 7) as the 06828 value. I follow his method to calculate my desire 06828 value (FDD-LTE band 1, 2, 3, 4, 7) with the calculator and it DID came out to "79". i even copied all the NV values from the HK model to the China model and nothing happens....like u said..must be the antenna was hardward litmited.

US LTE network uses band 2 and 4, if your phone or tabalet support those 2 band then u should have no problem connect to LTE.

Sadly, Hongkong, Taiwan, and Singapore model of Redmi NOTE 4G is the ONLY Xiaomi phone that supports US LTE network, nothing else, not Mi4 LTE, Mi NOTE, Redmi 2, Redmi 2A.....i hope the upcoming Mi NOTE PRO and Mi 4i will gonna support Global LTE band....just keep my fingers cross>>>>
[Redmi Note General] skezza:
After unlocking Band 20 manually, I noticed a surprising drop in network performance, in particular 4G. I wonder if there's some logic in the code to prioritize other bands if 4G signal is low or in certain areas or something...? With Band 20 unlocked but not functioning, this means that there would be no signal discovered. In particular, a very good 4G location seemed to revert to HSPDA+ almost entirely apart from a small area which continued to give 4G. Yet 4G networking was possible manually. If I disabled 3G altogether, and just switched to LTE only, 4G network was fine, so I believe there's perhaps some code in the modem to prioritize bands. This would actually make sense because Band 20 is for indoor, long range and more versatile use, whereas other bands are for outdoor and short range. Therefore band 20 would usually be prioritized over other bands otherwise you'd get unstable signal when switching from different bands.

Just a heads up guys.
[Redmi Note General] michalurban:
Great news about this software engineering project moving!!! :good::good::good:

Just to make sure - is band 20 really intended for indoor use? I read about the different use of the FDD frequencies and then I asked our (Czech) three providers about the FDD-LTE frequencies - and they all (of course) stated that the main part of Czechia is and will be covered with FDD 800mHz (Band 20), while only the largest cities are and will be on FDD 1800mHz (Band 3). So I thought band 20 is more for outdoor, while band 3 is more for indoor use.

PS: Don't take this the wrong way - I'm just curious ... :)
[Redmi Note General] skezza:
Short wavelength, therefore the signal travels way further and is less prone to object interference like walls, trees, cars etc. However short wavelength does mean slower 4G.

Long wavelength (2600mhz as in band 7) will travel shortest distance and will be prone to walls etc. However longest wave means fastest speed.

Hope this helps.

International versus China version

George, great tutorial. In beginning of your post you mention something about international version (support b3/7...). Are you aware of different versions with different band configs?

Thanks
[Redmi Note General] hamizal:
guys pls guide me...im want unlock this 3 of band :: 3(1800), 7(2600)41(2500)
[Redmi Note General] michalurban:
Any new information on this, please? Are you running on 4G-only now? And one more question:

The LTE coverage (FDD 800) is quite good in my country. So I was thinking I could enable B20 and set the phone to 2G a 4G only, so that I could use LTE mostly but have some connection when outside of the covered area. Is that possible?
[Redmi Note General] mp3elv:
So in sum and without sidetracking is it possible or not possible to enable LTE Bands, on Xiaomi MI Note, or not, basicly cos i need Bands 2 and 4, which are not supported by the device officially, but as far as i know from this thread only the LTE band 20 in UK wouldnt work? would enabling the bands 2 and 4 work?

Also i read about the Redmi Note 4G hong kong and global posts where it says that this trick wouldnt work, is that an isolated case? would changing the values in the NVRAM enough to enable new bands? is it something tied to physical antennas? or is it tied to the baseband modem besides the NVRAM please someone show some light on this, it's a tad confusing.
[Redmi Note General] kinto92:
Check the the OPO LTE Unlocking guide which you find here.

Bands 5 and 20 are not available on the hardware. However with this you can use the phone in the US.
[Redmi Note General] mp3elv:
I wonder if it is too much to ask for a complete answer, as i said it's confusing and after reading it all there's nothing clear, if someone got it clear could tell me, if this modification of the NVRAM works with this very specific model Xiaomi Mi Note? i know there's a oneplus and oppo threads, but given the answers that i have found in this thread i cant really be sure if it works or not, after all in the 2nd or 3rd page there are entries where people say it doesnt work, so maybe more than a one liner would be good please?

Has anyone successfully unlocked bands 4/12/17?
[Redmi Note General] davekaye:
Tried to unlock AT&T US LTE

Thanks to the instructions from OP, I tried to unlock AT&T USA bands 2,4,5,17. I replaced the original values completely. My DEC result was 65562. Using QXDM I modified my values. Unfortunately, I'm still on AT&T 3G H+. No LTE signals. I bought my Note 4G in Malaysia. I can't believe that Xiaomi is making different hardware models for sale in different countries. How would they keep their costs and inventory in control? So maybe there is something else needed. My OS is MIUI 6.4.2 Stable.

So for the present, unless I hear otherwise, opening up USA LTE bands does not seem to work. :(
[Redmi Note General] thorazine74:
Q: reading some of the guides I've seen some mentions of anti tampering code added to recent versions of android to avoid this band unlocking, if this is the case with miui kernel wouldnt we need a custom kernel with this anti tampering code removed ?
[Redmi Note General] pangster:
I've read the same??.. any ideas??
[Redmi Note General] davekaye:
Until somebody creates a new Kernel for Note that doesn't have anti-tampering code we will not know. Although Xiaomi has released their Kernel source, I can't seem to find any new Kernels here or on the MIUI site. It's beyond my skill capability to build one....
[Redmi Note General] gkan:
Thanks! it worked!

Hi,

I'm not a mobile geek but I followed this master thread and it helped a lot but initially didn't worked on my Redmi Note 1LTE later tried below 2 scenario's and they both worked.

Scenario - 1

I followed the same steps on my Indian version - purchased device through Flipkart.com hope it was manufactured probably for indian carriers and few other Asian carriers as it did not worked on US mobile operators like I tried AT&T & T-Mobile, well I followed same steps as per this master thread including NV memory values and I'm happy to share here that it worked on my mobile - Redmi Note 1LTE. Only tweak I did was values set under and changed them to ID: 06828 to '79' and ID: 06829 to '0' (zero), also update values for ID: 0441 to to 0x380, ID: 01877 to 562950052512131 , ID: 0946 to 0x05E8, ID: 02954 to 131072,

Rest all steps are same as per master thread and it worked!!!

Scenario - 2

use qpst/qxdm soft's take a backup of actively working one and restore onto the one which is not working.

Party time :)

So a couple of questions?

Where are you getting codes, 0441, 01877, 0946, and 02954 you mention in your note that you changed.

My Model # is HM Note 1LTE in the Settings/About Phone. I purchased it in Malaysia, not realizing it wouldn't support USA LTE bands for AT&T or T-Mobile (although works fine on 3G H+). Also, what is scenario #2 in your note. I assume that means finding a working backup from a Singapore or Hong Kong phone that supports USA LTE bands and if so, does anybody know where we can find somebody with that phone who would put the backup into this forum.

Any assistance is appreciated.

Hi!

I config' my Mi Note follow by the instructions. I need unlock only band 1 (2100) because provider in my country use this band to service both of 3G and LTE.

I have a Mi Note Pro, my original values are : 2061584302149 / 11110000000000000000000000000000001000101

Rogers supports the following frequncies:

GSM/EDGE Bands: 850/900/1800/1900

HSPA+/HSPA Bands: 850/1900/2100

The LTE for Rogers is classified as 1700/2100/2600 combined also known as AWS.

Edit: So I changed my value to: 2061584826581 / 11110000000000000000010000000000011010101

Edit: Not working... I get on and off 3G and H+ only... No LTE...Can anyone help? Do I have the correct values?

Edit: Make changes and try to enable these:

4G bands: LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 17(700), 20(800), 28(700)

Which equals to: 11110000000010000000100100010000011011111

nv_lte_bc_config_type.lts_bc_config = 2061853925599

Update: I got LTE on Rogers with the above setting! YAY! It says 4G :)

Which version to buy?

Hello Everybody,

I am from the US, but live in China and would like to buy the Xiaomi Redmi Note 4G and unlock the bands. Which version of the phone should I buy, the international/HK version or the Chinese version and where do you recommend that I buy it? If I buy the Chinese version can I add the necessary bands to get it to work in the US? Seems as though the earlier posts say it's not possible with the Chinese version, I just wanted to confirm. By the way, this is the link to the international version (Model Number 2014715) specs....it will work in the USA right out of the box: http://pdadb.net/index.php?m=specs&id=7029&c=xiaomi_hongmi_note_1__redmi_note_lte_2014715
