Dears,
I would like to know if Redmi 4x supports carrier aggregation between B1 and B3?
I modified CA NV values using QXDM but still not working for me
Did anyone try carrier aggregation for any bands and it worked for him
Thanks

We can check supported 4G Carrier Aggregation combinations of this device by sending log to me. Here is instruction how to get log out: https://mt-tech.fi/en/how-to-get-4g...tions-from-your-android-phone/#Xiaomi_devices . You can send log to: https://cacombos.com/contribute

Hello,
Now with bootloader unlock & Root is it possible to Unlock Band 20 for 4G ?( actually i saw it used to cdma (800mhz) )
I live in France so i don't need CDMA , only 4G and GSM Band.
Regards,

Probably, search for those threads that show how to install the HTC modem driver and use QXDM to change the LTE bands. This is assuming that there is hardware support.
You can use NV Calculator or LTE Band Calculator to get the needed value.
You'll have to boot into bootloader and boot to BP Tools in order to install the modem driver on your computer.
hi tell me the spc code what u using I'm qxdm .. ?? mine 000000 is not working pls help me .. how to get spc code

I don't think I've ever been prompted to enter a code in QXDM. Everything is done from the PC after booting BP Tools on the phone.
OK I will try

Sorry to disappoint you, but can't be done. Many people have tried to enable LTE band 20 on the Moto XT1225 (and it would be seemingly be more possible with that Quark variant which was sold internationally, rather than the U.S. XT1254)
Using NV calculator, QXDM, QPST, etc, the software changes will show LTE band 20 is enabled but you still won't actually receive/send any signal.
Hi! 4G isnt working on my Mi9 with A1 network but they use the suported frequencies. I tried reseting APN and some other changes in developer options nothing worked. Any idea?
I'm gona try and flash the ROM when I unlock it from CN to global or EEA. which one should I chose if there is any big difference?

Which variant do you have? if it's the alita / explorer / transparent edition (8/256GB or 12/256GB) then there's NO BAND 20, which is LTE for many providers. Have you checked this?
EDIT: see here, perhaps you're in an area that doesn't use band 7 and only band 20? If this is the case... No ROM you flash can alter that, it's hardware related. ONLY global devices (64/128GB) support band 20

I have transparet ediotion 8/256gb. Checked there is no band 20 in my area but 4g works everywhere else
Should I still flash the ROM to global or eea? Can I relock it after or is it gona brick..

Do not relock bootloader after flashing rom, it will most likely brick your device. Flash another ROM if you like but you won't get band 20
May I ask, why do you want to relock bootloader after flashing a new ROM?
Hey guys,
Anyone tried flashing xiaomi EEA rom or EEA modem on other devices ( raphaelin, raphael, etc), as the EEA rom supports more of the bands required for carrier aggregation (CA) ?, we will definitely see a bump in network speeds, as the current ones aren't upto the mark, xiaomi cheaped out on CA, not buying licenses from Qualcomm. So i guess, this is worth a shot, I understand that EEA isn't updated as frequently, but still?
Thanks
The ROM has nothing to do with what bands are supported. Flashing a different ROM will not enable or disable any bands
Bands are dependant on the modem which is only editable through a specific qualcomm tool
As far as I know still 855 SoC is not supported in this tool
It is not a file you can flash through fastboot or recovery

Not bands guys, i was talking about ca, which we can enable via tool "Qxdm", but as said above, it doesn't support sd855 yet . Maybe flashing EEA modem will get us carrier aggregation? ?

This is the same tool that had been used to enable bands. It does it by modifying the nvram but the modem on the K20 Pro is locked so the nvram cannot be modified. There is already a similar tool that supports the SD855 but it doesn't work on the K20 Pro because of its locked modem
Hello. 5G network is comming soon . I make today method for unlock 5G on 700mhz for this device . Problematic is only icon od network because 5G network is visible as 4G (have only 4G icon , but work in 5G mode , speedtest say the same) . Unlock method to avalaible soon , and publish in this thread . This method unlock all bands supported by device . Avalaible info about device is on frequencycheck.com with all bands . Unlocked all bands is visible on screenshot's in atach . What do you think about 5G on this device ???? Unlock 5G working only in european region devices and global . Devices from other regions have only unlocked new bands , I don't test this method on devices from other regions .
What you need to do that:
1.Any Qualcomm device - with this guide you unlock only Qualcomm cpu devices
2.NV values
3.QPST and QXDM for edit values
4.Installed lineageos with magisk
5.Network guru app for enable new bands after correct programing
6.ADB and FASTBOOT - with drivers to device too
7.Minimum 1 hour for do that
OK. Let's go:
Download drivers and flash lineageos with twrp - you need to install magisk and lineageos - Method for unlock don't work with stock miui .
Install drivers and turn on developer settings in your device and check 3 adb options for correct set all .
If you have magisk and lineagos , you can start adb and write command adb shell , in shell you need to write and press enter this command setprop sys.usb.config diag .
Start QPST and add port
Start QXDM , and find nv values (look down)
Change values and press write - do the same for second sim card (look up on qxdm and check dual sim , set this values for 0 and 1 if no possible you brick your device without option recovery signal. Write values to 0 and 1 after write press read and check . Do that with all values . Make copy of your values to notepad txt file for your safety . Reboot device , install network signal guru and lock all bands in 2G,3G,CDMA,4G . Device find 5G network on 700mhz as ''4G'' network because radio don't have icon and name for 5G .
More info and know how soon if i find some time for do that.
NV values:
0441: 0x780
0946: 0x0FF8
1877: 3460734838925428608
2954: 268894208
6828: 17591112253439
6829: 17591112253439
For enable total all bands in this device or other device with qualcomm cpu you must enter this values:
NV values:
0441: 0xFFFF
0946: 0xFFFF
1877: 18446744073709551615
2954: 4294967295
Values for LTE is not changed (LTE 6828 and 6829)
6828: 17591112253439
6829: 17591112253439
This values working on all rooted devices with qualcomm cpu inside with all wariants of cpu. If you want to share or publish this values write to me pm.
IMPORTANT: You must disable unused bands in EU if you are in EU in this app by uncheck in lock bands option CDMA frequencies . If you don't do that , your device to be scan all bands next five minutes than find signal !! If you are in other country , you can find in google frequencies used in your country and enable it only .
If you use my guide please press thanks

Tweaked system and unlocked radio give better speed of internet.

1.Mod move my thread here , from software development
2.I make test's with radio and calculations - possibly I unlock to 5G for 3,5Ghz+ if documentation of soc allow me for do that
3.I makeing know/how for users with instruction how to unlock radio
4.I make patched lineageos based on last available (look up) , with deodex for next unlocking
5.I need testers listen to me how to do all step by step , because one mistake, one point not do and you have hard brick radio and phone without signal ... i must end my work , users must have lineageos for correct unlock because magisk with stock rom not working and device don't have su libaries and busybox needed for unlock . Users and you bro must wait not too long . Say me what is your contry , i need to check bands for lte in your country and what is your model - I have from -EG series (backside phone have model) ????

Your device is fully support all bands in your country . https://www.frequencycheck.com/compatibility/05AZu0k/xiaomi-redmi-7a-dual-sim-td-lte-in-32gb-m1903c3ei-mzb7989in-mzb7800in-mzb8008in-xiaomi-pine/india .
Unlock bands for you don't do for you to much . But if you want to have option select band for faster internet do somthing for you . You need to install lineageos and to lineageos magisk and app guru network from play store .After unlock bands you find in network guru extra bands . You can try to check what what's band after select to be faster for you .
Soo... After update unlocked is all bands avalaible for this CPU . Actually soon I publish how to unlock all bands + 5Ghz Wi-Fi mode . All bands working correct.

On my device after little ''re-work'' agregation working , but i testing now it . Working stable .
5G network on 700mhz , but 700mhz working only in EU and maybe in US . 5 GHZ wifi , i plan to enable because CPU support that . I don't know why wifi on 5Ghz is disable , but I enable it later .
In india 5G network working , but i'm not sure band .

First try to use lineageos + network guru app and unlock all bands to values from second values and reboot . In guru app disable all cdma bands , activate all wcdma , gsm , lte and reboot . This possbile activate it automaticly , if not add comment .
Big thanks for that, I didn't know that is possible. Here in Germany we have Band 28 (700 MHz) for LTE (But also for 5G). Will it also be activated when I follow your instructions, or only for 5G? LTE B32 (1500 MHz) would be good too. Could you name the values for it? Or a guide on how to find them out?

Soo... Possbile you activate 2 bands 4G and 5G for 700mhz . You need only lineageos because i'm not sure how it working in stock rom . First published values unlock all bands of LTE and 5G too . For correct working please install network app guru , gapps
if you need , magisk for correct working of network guru app and lock bands all after unlock and reboot . If you after reboot lock in app all bands of lte you activate too 5G working . You can see in app band actually working , 700mhz working correct after unlock . I waiting for 700mhz in Poland because we don't have this band but i test in germany 700mhz (travel to germany in moment of tests 700mhz ) . Soon i Publish fixed lineageos for 5G and 4G network speed . My result of speed test in Poland after patch system and modem is actually : https://www.speedtest.net/my-result/a/6179268278 In Germany your speed test result can be faster than I have in Poland. You decide what you want to do with your device . 50% of unlocked bands for this device is here: https://www.frequencycheck.com/mode...al-dual-sim-td-lte-32gb-m1903c3eg-xiaomi-pine

Dear Experts,
Anyone here can confirm that SM-G781B has the 5G n40 capability? I was stuck in configuring my device to camp on this band, including:
- changing CSC,
- changing policyman files,
- forcing network by *#2263# (using G781BXXU1ATK1_THL can do this)
- upgrading to Android v11 by G781BXXU1BUA5_THL (to maintain it on Binary 1)
Is there any other way that I missed to make it work on n40? Any suggestion is welcome...
Thank you
xe
Yes it have but Samsung have Carrier Policy for 5G combinations and bands so may not be enabled your network.
Here you can check supported EN_DC combinations: https://cacombos.com/device/SM-G781B
hello olkitu,
Thanking you for your reply.... Is there any method to configure different EN-DC set of this device? My network do this: n40+b3+b1 and seems not supported by SM-G781B
