No luck using the guides for adding LTE bands yet. - Xiaomi Mi Note Pro

I tried all last night and today at adding US LTE bands and additional 3G bands. The phone took and is keeping the new NV values so far. However, as of yet, I haven't had any luck connecting to the T-Mobile LTE yet. With my limited knowledge, I think the Qualcomm chip is definitely capable of running those frequencies however the phones modem firmware doesn't have the coding to do so. I'll try and do a lot more research and figure out if I can pry into the modem firmware. If anyone has any knowledge about it then please share. This phone is simply amazing however LTE would just amplify that even more.
Here are the values I have been using in case you want to try them yourself. I kept all of the native 3g and LTE bands active in these as well.
New Values:
NV1877
0010000000000000000000000111111111000000001111000111 (Binary)

DF000100E001 (Byte Swapped hex)
2061584367839 (Decimal value for QXDM)
Just a note as well, you need build 422 of QPSD in order to do this. I tried 411 however the phone just kept showing up as an unknown device. Once I upgraded, everything was working fine.

Long time lurker, first time poster here
I'm looking into the same as you, tho I only need to add one frequency to lte to have all the needed frequencies in Norway
Did you have any success yet?

Not long
I have 4 weeks left of my contract, so unless someone finds away to unlock band 20 I will be changing after probably about 25 years.

I do not know why, but after last update, 5.7.2 now I have 4G working like a charm (in Spain)...

4G, as in WCDMA (HSDPA+) or LTE? Sorry I have to ask for clarification, different carrier/operator call them differently :/

Who you with and do you know which bands they use?

I'm with TELUS, here in Ontario/Canada, band 4.
But I'm also on another carrier, BELL, which has 2 (limited areas), 4, 7 and 17 (limited areas)

Has anyone tried this app to enable more LTE bands on the MI Note Pro? Im not total geek in understanding this, but I read on a post that a few people have enabled bands in Europe that were disabled...
play.google.com/store/apps/details?id=tw.rmstudio.mt.android.ltebandcalculator

Just switched providers today the 4G symbol is there, although speedtest says not as fast as H+ damn.

How do you enable all the bands?

Do you use the same guide for unlocking LTE on qualcomm?
Really interested to unlock the band 5, although band 40 served me well for now...

I got LTE on Rogers by following this guide and inputting my values:

Hello, I am just amazed at reading the thread you're linking to: that means one can get frequency not listed in phones specs??
I am wandering around xda for two years and I thought this was impossible.
I would love to get the 800Hz's LTE band if it is possible.

NO drawbacks, I went camping with it and I got a better reception comparing to the iPhone 6... My wife had EDGE, I had H+... I have dropped calls because changing the bands, now I don't

AWS would be cool.. is LTE 1900 doable?
I'm doing some more reading and am not scared of a hardhack.. glad to see there's a success story here.
Also a T-Mobile convert here. HSPA+ is still faster than what I had with Sprint LTE (laf), but I got spoiled with my brief foray into One Plus One full on both guns blazing LTE.

[Q] Would the T-Mobile HTC One work on Wind Mobile in Canada?

If I scavenge around this site and Google hard enough, I can find this question asked a few times, but none have definitive answers. This is a phone that I'm extremely interested in purchasing, as the Sony XPeria Z and Samsung Galaxy S 4 don't have an appeal remotely close to that of the HTC One's. Wind Mobile is a hard carrier to find phones for it seems, but I'd really love to use this phone on my network. Since the international and LTE variant lack the AWS 3G band to support Wind, would the T-Mobile version be compatible? On T-Mobile's website, it states that the UMTS Band IV is 1700/2100, which should be compatible with Wind's 3G network. I would just like to confirm this is true? Normally, I don't like to start new threads to a simple natured question like this, but I'm pretty much desperate to confirm whether or not I can use this phone. That way I'll know whether or not to get excited, or just stick with my S3. Thanks, it's much appreciated.

Was on wind in the past, yea it's hard to find devices for this carrier because it's strictly on AWS for its data and services.
The HTC One might work...but if I recall correctly you need 1700/1900/2100 frequencies for HSPA+ or something.
If it's anything like the original Galaxy Note, you may have to flash a radio or something to make it compatible with wind IF this phone is pentaband. If it isn't, f forget it because no amount of radio flashing will work if it the hardware doesn't support it.

I'm out of country right now, so once I'm back I will post it. By the way t-mobile uses the same bands as wind mobile, apart from having lte also. Other than that there's no differences...T-mobile one has 1700/2100/850/1900

Sorry if that wasn't clear, but the picture is actually linked to dropbox, if you follow it, you'll see that its a screenshot of my TMo HTC One working with the "WIND Home" carrier ID clearly visible.
Anyone know the Stock ROM/or RUU for WIND Mobile??

I might be in a re-farmed area, but so far I'm getting 4g, and LTE exactly the same as my tmobile iphone 5. Maybe it's already AWS unlocked? How do I tell?
I do want to confirm that I am getting AWS on my factory unlocked S4 Active with no mods. e, 3g, 4g, and LTE. I know this because on my hacked note 2 without the AWS mod i couldn't get all that.

Yes, I got the unlock code from them yesterday and the first thing I did was to pop my TMO sim in. Only 3G for me. So then I check my apn settings and configure it for fast.tmo but that doesn't even connect up, had to us EPC.tmo for the 3g to connect.
Did you have to mess with your APN settings?
It took about 3 minutes after putting the SIM in for it to auto configure. Then rebooted and data came online all bands. APN is epc.
Maybe you need a different SIM?

I'd have to second the notion that you might need a new SIM.
I've been taking screen shots. I've had every data possible. e, 3g, h+, 4g, and LTE. The ATT unlock code definately unlocks the AWS flag in the NVRAM.

When I got the code from AT&T it took less than 10mins and I don't even have AT&T. But now they got a new rule about giving unlock codes I had to call twice because the first person wouldn't give me the code but the second did.

If you refer to my post, my point was only that there's a little app that shows the Android service menu. The band is indicated (mine says HSPA - my contract doesn't allow LTE, so I can't say anything about that).

that app your referring to is the same menu as going into *#*#4636#*#*
also, HSPA, LTE, GSM, etc is not the band type, its a network type.. by Band type I mean LTE: Bands: 1/3/4/7/17/38/40, which is also another way to describe radio frequency
as you can see in the first pic of my first post, in the Samsung device, it shows Band 4
but my question was for mindblizzard,
I don't think the phone can show that information

That's all fine and dandy, but it's not like your carrier is operating multiple frequencies that you're likely to see ever. Maybe if you live in an incredibly dense population center, but even then... Perhaps I'm missing something.

Fair enough, if you have LTE already, and they are simply deploying a new frequency, you likely won't notice any change, to any of the service. Speeds don't increase between bands, the only reason a carrier deploys a new band, is to fight radio interference from other carriers. Given the cost of a single radio, carriers generally only deploy these new radios in VERY congested areas. Meaning, that in a city that has, say 15 towers, 2-3 of them would actually get the upgrade, in the area that suffers from the most interference. (You have to bear in mind, that a full tower build, requires 6 radios, each radio costing about $18,000 for the radio, another $1000 for the antenna, another $500-1500 for the power supply and cabling. They don't just "upgrade" an entire area, it takes too long to recoup costs)

Ah my mistake, i had in my head he meant to check for bands in the area which he can use with the 'unlocked' frequency mod..for some reason. My total mistake!
However what i meant with what i said when i get my 4g is that i can confirm that the unlock mod will enable band 20 since our OPO is restricted/doesnt support it by default. The band app would be good though!

Exynos variant

Can anyone confirm the compatibility of the Exynos variant with T-mobile? Frequency check websites show 100% compatibility but looking for personal experience feedback. Also curious if B66 works as intended in the US.

Anyone play around with the idea of loading the T-mobile S8 firmware onto the Exynos international version of the phone to see if that would be enough to get Wifi calling working? Wifi calling is essential to me since I work in a building with great wifi but no service.

You cannot install Snapdragon firmware on an Exynos based phone. This will lead to a brick. The only thing from a Snapdragon firmware you can install I believe is CSC but don't quote me on that.

I was also wondering if flashing the tmobile CSC to the 955F would enable wifi calling. The only LTE band that the Exynos variant doesn't have that T-mobile uses is 66 and from what I've been able to research that's not sued int he NYC area. But wifi calling is critical. I use it a lot to call back home when I travel abroad.

Thanks but there's something weird about your screenshot. Band 32 is out of order and is not used on any Samsung phone. I think that should be 42. I find it hard to believe that there is a typo in the service menu.
I was using frequencycheck.com and willmydevicework.com as my sources. I agree that on this point I'm positive that the 950 and 955 should be the same.

Yeah it's strange and I do think it's a typo. But that's what service mode shows, regardless of which SIM I select.
With the exynos you'll also lose VoLTE. Meaning in areas where T-Mobile is using B12 LTE to extend the range of its network (B12 LTE 700mhz goes further than their EDGE and HSPA network (1700,1900,2100mhz) so if you're in an area and only have B12 LTE signal you won't be able to make or receive calls or texts. And in an emergency scenario if there was no other network for your phone to roam to, you also wouldn't be able to dial 911. Kinda an important feature imo.
I use the 930F on t-mobile and will likely do the same with the s8. If you care about rooting, you should get a 950f. It can be rooted easily and with root, you can get TKKG1994's CSC selection tool and use it to enable VOLTE/Wifi calling). If you aren't going to root, then the carrier phone is good.
I don't know how gigabit LTE is affected but I doubt in 2017 this is a game changer.

T MOBILE Speed is low on FD models?

I remember when I had the note 8 N Version you had to change csc but don't think csc change does anything lol

i'm using the 960F/DS, with an ATT CSC and i get HD Voice with both ATT and T-Mobile calls (i see the HD symbol on the Google Dialer/Phone). i've been very happy with my T-Mobile LTE cellular internet speeds in my low-signal coverage neighborhood. will test again and post results from current biz trip where T-Mobile has excellent coverage on internet speeds.

i didn't use the flash method; couldn't find a flashable file with an ATT CSC for the Note9. so...i extracted and copied-pasted the ATT CSC folder/files from ATT's most recent full ROM and manually edited the necessary dat files in the omc and /efs/imei folders on my phone. that being said, neither ATT nor T-Mobile WiFi calling and video calling work, but that's not an issue for me. i use the Google Dialer and Duo for video calls.

Clever.
I have both working but I need speed more than voice lte since I barely talk on the phone
And use what'sapp
T-Mo cellular internet speeds in DC... Remember this is with an AT&T CSC configuration on my dual SIM note 9, with TMobile SIM selected for calls, text and data.

What MCCI code did you use to access the services menu on your Note 9?

thanks for the link; i figured out the codes shortly after posting my message.
Rather than turning off band that provider might actually use in some situations, try turning off band that you possibly won't use, like band 39, or whatever.
See if that fixes preference to band 4, while still maintaining band 12 for odd situation.
I'm only saying this, because in Canada for provider freedom, band 66 is the fastest, and international phones actually prefer to connect to band 4 which is the slowest for this particular provider. Since we don't have access to modem settings since oreo, I found that disabling any of the unused bands (30,46,39 whatever), brings back proper behaviour like Canadian model counterparts, choosing band 66 majority of times, while still maintaining band 4 for building penetration.
Just try, give a few minutes, check on *#0011#, see if you're still defaulting to 12, or something else with more throughput, might work, might not.
