Hi, is it possible for me to change (and stay that way) the LTE bands on my phone without root? My network seems very slow on band 5 LTE and I'm looking to change it to band 38 or 40 instead. Thanks
Base on my experience, it's impossible not to root your phone and change system files.
I already have both bands on, it's just the matter of preferring one band over the other. I tried manually to search networks in the advance tab and managed to connect manually for a minute to band 40 network before it automatically changes back to band 5 ( even i selected thr the network manually)

Is there any way to configure the UMTS Band settings on the Trinity / D810? I ask as the ROM provides the following options:
Network Type:
Auto
GSM
WCDMA
GSM/UMTS Band:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Now ... for the HSDPA Network in Australia for Telstra (Next G), I need the phone to work on the UMTS(850) Band. However, by selecting the option above where the only UMTS(850) is available means that the alternate 3G Band (not HSDPA) of UMTS(2100) is not available, and the GSM Bands in the same selection are not valid for the Australian market.
Couple of queries, and I hope there are ways of configuring the device to achieve this (without getting a new ROM to support it):
When a Band selection is made, what is the order which the device uses the connections? ... i.e. if the selection was GSM(1900+850)+UMTS(1900+850), will it look for UMTS or GSM first? If UMTS, which band - 1900 or 850?
When Auto is selected, I am guessing it uses each option in the list until it finds a valid network? This would mean that for Australia, if left on Auto, you would never select HSDPA for Telstra as it would find the 3G UMTS(2100) network first (non-HSDPA).
My assumptions are that if left on Auto, it looks based on list order (which is the network order in the registry). So, for Australia, I need a setting like the following:
GSM(900+1800)+UMTS(850+2100)
Is it possible to create this Band Selection without a new ROM?

The new Dopod ROM has the same band selections as yours does. I tried changing the selections to manual with bad results. I just leave it on auto now.

I could do that to, but it would mean I don't get HSDPA. I have verified this. The only way to get HSDPA is to set the Band selection to the one with UMTS(850) in it ... this is not ideal, and that's why I posed the question to this forum.
No one??
I am guessing that no one has ever come across this, or needed to do it?
Registry Patch
This Registry patch works for the Hermes. It might work on the Trinity.
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhoneSetting\BandType]
"ItemCount"=dword:00000006
"ItemName1"="Auto"
"ItemName2"="GSM(900+1800)+UMTS(2100)"
"ItemName3"="GSM(1900+850)+UMTS(1900+850)"
"ItemName4"="UMTS(2100+800)"
"ItemName5"="GSM(900+1800)+UMTS(2100+850)"
"ItemName6"="GSM(900+1800)+UMTS(850)"
"ItemValue1"=dword:00000000
"ItemValue2"=dword:00000001
"ItemValue3"=dword:00000002
"ItemValue4"=dword:00000003
"ItemValue5"=dword:00000004
"ItemValue6"=dword:00000005
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\UMTS\BandSelection]
"Band"=dword:00000005
You really just need to add ItemName5 and 6, and ItemValue5 and 6, and change the ItemCount from 4 to 6 (as you added two options) using your favorite Registry Editor.
Do a soft reboot of the phone. Now you can select the NextG option GSM(900+1800)+UMTS(850)
3G connection
I drive around the Perth Metro area a lot for work and am finding that if left on Auto the connection is lost quite often mid call. How have you found the 810's management of the bands? And the auto fallback? Is there a way to set the fallback threshold so it drops back if under 2 bar signal strength? At the moment it sits on 1 bar strength and drops out mid call.
Is there anyway to force LTE band change between bands 13 and 4? At home, I have one bar on band 4, but get 60 dl, and 30 up. However, on band 13 I'll get full bars and get 30 dl, 15 up. I don't use my data at home as I am always on wifi, so this cell standby battery drain is murder. If I reset my data connection it will connect to band 13 initially, but it will then change to band 4. Switching my carrier is not an option as T-Mobile, Sprint, and AT&T get equally crap reception and I'm still under contract with Verizon which ends in October. Maybe then I might think about switching to project fi.
I've seen other threads on disabling certain bands, but those bands are only used by T-Mobile and Sprint, so they are of no use to me. Any ideas?
There is a thread about 4G/LTE.

Further search the play store for 4g switching apps.

I've seen that thread but it doesn't say anything about removing or blocking certain bands. As for the 4g switcher apps they only have he ability to change LTE modes via CDMA or GSM
The last idea, in case you use a Nexus 6.
There is thread with flashable radio's.
Maybe you can find an older radio that doesn't have the bands you don't want.

Yeah, i tried flashing the oldest radio listed and it's still a no go, band 4 still seems to be enabled. :/

No more ideas; think it is not possible to disable band 4, without hacking/patching the radio image.

For now I have my connection as 2g whenever I'm on wifi so that should fix the cell standby for now.

I have the same because here in the Netherlands we have the so called 4G. But when I am home (inside) there is bad connection. Phone calls are disconnected frequently.
With 2G very good reception at home.
On the road I switch to 4G when I need internet.
I use an app to quickly switch 2G-4G.
It's a rather old app of CurveFish and is in the play store - 2G 3G -
I have exact same problem but problem of speed.
There are 3 lte bands 850mhz,1800mhz and 2300 mhz.
2300 mhz has highest speed which i want my redmi note 3 to run on only but in my home it only switches between 850 mhz and 1800 mhz.
Searched a lot but not able to find any guide which allows to lock the frequency to 2300 mhz band only. The signal bar is also 3-4 on 2300 mhz still it connects to 850 and 1800 mhz most of the time unless i am in open area outside house then it switches to 2300mhz band.
Use QXDM

Hi - not sure if this is still a topic of interest, but you can use QXDM software to achieve this - you just need to change NV line 6828 to be "4096" decimal value. On the Nexus 6, this is a fairly easy process as you just need to boot to bootloader and select "BP Tools" as your boot-up option and then the phone will be in diagnostic mode to connect to a PC. There's info out there on XDA with more detail, but as long as you can successfully install the Motorola/Qualcomm drivers you can fairly easily restrict LTE bands to whatever combination you'd like.
Be aware - some say this is a risky operation but I've not found that to be the case. But there is a chance of messing up your device if you're not careful.
Take a look at the "NV Calculator" app in the Play Store for additional info on determining decimal values for the LTE bands (you might want to keep band 2, for instance, as Verizon uses that sometimes as well).
Here's more info on this on XDA:

Good luck!
Hello all,
I recently changed my phone carrier, and I noticed phone doesn't go in LTE+ mode anymore. Apparently, the phone is able to aggregate band 3 and 1, which was the combination my previous carrier was using, but not 3 and 7.
I read a bit around, and found out some useful discussion here:
http://en.miui.com/forum.php?mod=redirect&goto=findpost&ptid=392070&pid=10016974
which gave me the opportunity to understand how to set the carrier aggregation on different bands, and avoid to add any combination on band 7 which apparently isn't managed properly.
So, I used QXDM to change the nvram values on band 3 CA (default is 5, which is band 3+1 aggregation), and my phone was able to aggregate 3+7 bands, but that leads to a loop between LTE+ and LTE, which ends with phone in H.
After reverting the changes, phone goes normally in LTE.
Is there any way to enable Carrier aggregation on Mi 5, on combinations not originally present in the firmware? Or does Mi 5 lack the hardware to do so?

I dont really have the technical knowledge, but if you look at some of band 1 configs, there's a few values that are set for carrier aggregation that are not set for other bands. I think we need to configure a few more things than just enabling the CA values. Been trying to figure this out for some time. Too bad i don't have any other phone with proper ca support to compare
does the *#*#717717#*#* only works in MIUI ? currently using OMNI rom

There are some, only usable one in Italy is on band 3, it aggregates 3 and 1, but is really rare operators use this config.
You can enable the engineering mode with adb
Hey guys,
xda still going strong. nice to see.
need some help though.
i bought a note 8(yes in 2020) for some reason(side device) and i got stuck with a problem right away.
i noticed that TDD LTE bands(band 34,38,39,40,41) are all missing from my device.
i am having an exynos varient (n950f)
i was monitoring my network from past 2 days and 3ca was working fine. i was connected to 3,5 and band 40 all together.
i wanted better reception so went in network selection mode and selected band 5 preffered. i dialed *#0011# to check my ca status and i was still transmitting on all 3 bands with speeds well over 100mbps.
after some time my speeds died and i no longer see band 40 in *#0011# menu and i have tried restarting device and what not but still cant connect to band 40.
i am pretty sure TDD LTE bands including band 40 was missing from band selection menu earlier too but things were just fine. not i am stuck with a expensive device that fails badly.
please help.
on some inspection i observed that my phones is continously doing 2ca even when using no major data on band 3 and 5.
basic is stuck on band 3 and s1 on band 5. me changing to whatever setting in band selection in hiddennetworksetting dont affect it.
tried selecting bands that my operator dont even support. not in preffered mode but as the only hard selection. makes no diffrence. network signals shuts for a second and i am back on band 3 and 5 combo
So I Tried To Disable Band 40 And Only Enabling Band 3 or 5 But It Didn't work Band 40 Keeps Re-enabling itself,it affects me cause in my area Band 40 is slow Band 3 is Faster Band 5 is the Fastest(Tested with my POCO F1). I also Rooted the Phone and then tried using some apps like network signal guru etc. but they dont work cause they only Support Qualcomm. Is There Anyone who can help me with this?
I am using M2003J15SI Model,Using Jio,MIUI 12
Thank You.

I am also having the same situation with my Redmi Note 9 (Global Version). It keeps rechecking the band 40. However, I think that it just keeps rechecking by display only, when in fact it is really turned off. For example, I am currently in band 40, then I unchecked band 40, leaving only band 3 checked. When I check the band selection again, band 40 was checked. But when I check the band in the "Network Monitor Lite" app, it is connected to band 3. So I think, it only displays (checks) the band 40 when in fact it is really turned off. Thanks
