Hi,
I want to take your approach on my Redmi Note 9S. Is there any guide I can take to enable 4G+ carrier aggregation?

For some reason, it didn't work even after following so many guides on XDA. This inclusive.
I think there's more to just editing values on QXDM for my device.

There are some useful guide for sony phones there, might also work elsewhere, or at least help you to understand how it works.

Nubia Z7 mini (NX507J): Adding LTE bands

For the beginnings of this thread read posts 838-844 here.
alain57 said:
I did the modification on cucuo92 rom
i went back to CM12.1 and noticed that TWRP restaure an NV partition... So i first told TWRP to NOT restaure this partition => phone did not boot
So i had no choice and restaured this partition after all
well I went to a town where there is ONLY LTE 800Mhz, and like I expected did not work :/
So I guess that the NV partition backup in TWRP contains the NV changes :/
Nevertheless, i'll retry this with Cucuo92 rom to be sure that this mod is working on my phone
if it is, i will create a NV backup and try to compare it with the backup I already have (cucuo rom without changes)
and then I'll try to do the exact same difference on the CM12.1 NV backup... maybe this could work
you need to use another tool to do the LTE mod, the window you are showing is the one for UMTS (3G) modification
this window need to stay open, but the LTE mod are done in one other tool

So I was reading a little deeper in the thread and a few interesting things came out to me.
CM is known (as of last September) to have added a commit to their code to prevent these changes (my guess is because of their rapid growth and wanting to play with the big manufacturers), so CM12 or CM12.1 may not successfully do this.
It seems that this only works with custom ROM's/kernels that have been compiled from source (meaning Cuoco's ROM is built off of Nubia and they likely are preventing it in the kernel)
It seems the phone has the correct modem to make this happen, but we may also need a custom radio compiled to enable these bands to work - although it seems some people in the other thread have had issues with this. Some say it works and others not so much.
There's more but I don't have time at the moment. I'll try and add more later.

The guy that stated he tried it said to use Cuoco 2.50 or so, and that it didn't work on CM. Maybe Nubia does not have the temper code in its firmware.

Exact I stay under Cuoco 2.51 because I love this rom, but maybe the guide work with CM...

This is true, they may not. It was only a presumption on my part. They have been so reluctant (okay, flat out refusing to do so) to release the source code and device tree, it wouldn't surprise me that they have this, I just don't know. Nubia/ZTE really seems like they don't care about anyone outside of China.

From what I understand from reading many of the replies in the guide, people have had a hard time making it work with CM. They have to use a different ROM.

well fo me, i enabled band 3, 7 and 20 only with the code number : 524356
I then went to a town where to only LTE is on band 20 (800Mhz) (i checked this on a french 4G => http://www.reseau4g.info/couverture-4g-orange)
and ....
NOT WORKING only 3G (too good to be true)
good part about this : i now has no reason to stay on that ****ty nubia based rom, can switch back to CM12.1

Are you sure you have activates 4G in settings > Msim Settings > Mobile Network > Phone Card One or Two ( Where is your Orange sim card ) > 4G mode, enable LTE 4G networks

yes as I have currently 4G in roaming on a 2600Mhz antenna
these are the settings i setup (i also wrote the second line just in case, but this didn't help :/)
and like I said, i'm currently in 4G but on a 2600Mhz antenna somewhere else
---------- Post added at 11:19 AM ---------- Previous post was at 10:47 AM ----------
at least i can confirm that disabling a band really disable it
i just setup my phone to ONLY accept band 20, rebooted it and no more 4G at the place I am (with 4G 2600Mhz)
I guess that some manufacturer disable some bands by software (and in this case, this mod works)
and some other may actually have some hardware limitations (maybe the LTE radio can't find signals bellow 1000mhz ?
nevertheless, i will do a last test by activation all 800Mhz bands (and for course the 3 an 7 bands)
so it will be bands :
3 6 7 18 19 20 27
for code i received 68026468
I'll test this this afternoon... and update the post after getting some results
edit : i went eating in the other nearby town (800Mhz) and no 4G
so this modification is useless :/

Okay, so it seems that we've had someone on Cuoco and on Nubia test this out without success. Next we need someone with one of the versions of CM to see if it works. I'm on CM12.1 and would try, but I don't have a PC; only Mac and Linux and I'm not sure how to make this work with either one.

Well for cm12 we first need to find how to enable the dialog USB.
Cm12 only get adb and mtp or USB mass storage
And noe of the service code worked...

You have it explained here - http://forum.xda-developers.com/showpost.php?p=57561965&postcount=1
You may actually control all the possible USB configs in a similar way.
And it works on a fully booted phone, and not when swiched-off.

intresting thread, i want to buy a z9 mini... there is also no FDD-LTE 20 (800mhz) for being usable in Germany...
anybody tried this? http://forum.xda-developers.com/showpost.php?p=55560160&postcount=148
other question, could it be that the reciever isnt possible to get 800mhz? Then the Software edit would be not useful

Had not seen that specific thread; although, the person who wrote it was a major contributor to the one that had been pointed out earlier. A couple of the people here tried adding band 20 (in France I think) and it didn't work. From what I understand, the qualcomm modem should work without a problem, it's the radio that may be the issue. From what I've read elsewhere, if the phone is being used for bands 38-41 in China, the antenna should be suitable for the other bands people are looking into activating on the phone.

Yes, it does, but those bands aren't available in all countries. Those are TDD bands primarily used in Asian countries (thought there are others too).

yes , but you said:

but the OPO hast 38-41 and the FDD20 didnt work, see my last link
thats y iam asking.... depends on antenna, or software? Because Qualcomm Tool should be able to active FDD 20 on Qualcomm based phones.. but if the antenna doesnt support, this all is useless, thats the question now?? mhm

https://www.qualcomm.com/products/snapdragon/modems
this is also very intressting... the LTE modem is buidl in @ processor , so it shoudl be able to add all LTE bands...
but now there is also the question if the antenna is a impotant thing or not?
for exmaple on the Nubia z9 mini, there is snapdragon 615, which is alos build in htc desire 820, Oppo R5 , Coolpad F2 LTE, Samsung Galaxy A7, ZTE Blade S6
only F2 and blade s6 dont support the 800mhz LTE band, the other 3 do...
br
edit: i see the s6 also has b20 support now
http://www.comebuy.com/brandpage/specification.html

The B20 band is possible or not on Z7 mini ?
I'm sorry but i don't have the capacities to test it.
But actually the procedure for SOC qualcomm don't work for our device ?

hello
Hi everyone, I am trying to enable some lte bands.
I can not make service programming to read my phone. is it totally necessary? becasue qspt and qxdm are reading my phone.
I wrote with qxdm 65609 for bands 1, 4 17 (by the way, is this code alright?) but I can not get 4g to work. Any idea?
I am using quoco's rom
Thanks

LTE band 20 800MHz FDD
Hi did anyone successfull add band 20? Is it working? Can someone help me please? btw have cuocos rom

need someone with a redmi note 3 pro special edition- with root and twrp installed!

hey guys,
if someone of you ownes a redmi note 3 pro special edition and have root and twrp(alka) installed please contact me!
Thanks

I'm searching too and guess for the same reason (Band 20/28? ).
User wtfjajaja claims that he has a kate but he is not responding to my pm or in his thread :/
Also I found a user on MIUI with a kate but he is not responding either. Maybe I'm not polite enough

you are correct! it would be a huge help for us having a willing person with a special edition

Maybe you can PM him too and ask nicely for him to dump his device

Nobody haves a Kate

I'm sure there are people (why would they ask about porting kenzo fw to kate if they don't have one) but they are too lazy to help or fear that we could do something with their IMEI and such
edit: maybe we should try to trick people by saying our goal is to port cm to kate device hehehe

follow, soon to be redmi note 3 special edition owner. i would love to find out how to root and install twrp on this device!

Somebody have it in the forum but they say that special edition is 2 mm longer than kenzo. Some phsycal changes might be happen in hardware.

I would like to know this too. If Kate doesn't receive TWRP, I'd choose Kenzo, as it has such strong dev support. I use XMIUI and/or MIUI Tweaks too, and without TWRP and root, I couldn't install them.
It would be nice to have Marshmallow and band 28, but not at the expense of not having TWRP and root.

Just to bring this thread to a close, software-wise Kate is exactly the same as Kenzo apart from it uses a different modem. Now mine has been reflashed it can use all same ROMs as Kenzo etc.

VoLTE support

Hello. I am coming from a Galaxy Note 9, and I had VoLTE on that.
I currently have an EU version of the 7T Pro, and VoLTE doesn't work.
How can I tell if my device supports it? And is there a way to force it?
I checked my service provider's FDD-LTE bands, and my 7T Pro covers all of them.

Your device would have to be compatible with your carrier.
I have dual sim, so 2 carriers. Only 1 is supported for VoLTE. Not much you can do about it except ask your carrier.

Hi
for my provider (Vodafone Germany) its necessary to enable VOLTE by enabling them in the system config settings not available via menu. An easy way (in case you are rooted with Magisk) would be to install a magisk module doing this, I attached the one I use to this message...

I recall that with the OP devices I had before the 7 Pro VOLTE also didn't automatically work, even with the Magisk mod as this only activates it in the OS settings, but not in the carrier config on your phone.
There was a very helpful thread on a german android forum that outlined the steps to switch this config using a Qualcom tool, but that was for an OP6T and I'm not sure whether the basic procedure is still valid for the OP7T

Thanks a lot for your help, I would be very happy if I got VoLTE working, but this guide from this german forum didn't bring me any closer it seems, I can't even find the "VoLTE switch", "VoWiFi switch" and "VT switch" from step 1... I will be trying to do some research on it if there won't be some easy solution.. Strange thing is T-Mobile VoLTE works, but O2 doesn't, seems like a carrier issue, will try Vodafone some time soon.

I can find the Option under settings/WiFi+internet/Sim+Network/Sim1/VoLTE
Btw. I have O2, it's workig great.

Hello, Hello,
I have tried to to enable Volte and Vowifi with the magisk manager but I have failed to make the VoLTE and VoWifi to work with this way.I have tried a new simple way to enable them.You can download the attached file that is a Logkit that I have grabbed that from an article about activating this services for the OnePlus 7 Pro. I have tested that and I have enabled VoLTE(Greece-Cosmote) with success as you can see in the pictures.Its very simple and you will have to do these steps:
1)Download the attached Logkit
2)Install the Logkit
3)In the dialer type *#800#
4)Go to Oneplus Logkit and -> Function Switch
5)Enable VoLTE switch but don't reboot and enable VoWifi switch and then reboot.
After that you can enable from the sim card to have Volte and Vowifi , you can reboot and profit.
This solution has worked for me and I think that this is a good way to enable these services without magisk.

Works with Vodafone UK

For anyone interested... EE sims work out of the box (in fact you can't disable VoLTE easily for EE!)

I need a suitable profile
I try all profile but no one can make Volte work.

Hello,
100% working VoLTE & VoWiFi with Sosh carrier (Orange carrier digital brand) in France, with a 7t Pro McLaren Edition.
Many thanks!

On a side note for my 7T, does Volte have be in the banner , next to the signal, in order to work, Can I hide it and still be usable?
Thanks

How to enable Carrier Aggregation on CPH 1933 which is Oppo A5 2020?

Hi guys I just wanna know how to enable carrier aggregation on this phone. My carrier claims to have Carrier aggregation and yet I don't seem to be connected to any LTE-A or 4G+ connections. Is this phone CA automatic or do I have to do something about it?
Edit:
On the LTE Physical Channel Configuration, it is only just Primary no secondary.

LTE-A/4G+ should activate automatically if network and device support same combinations. I don't know what combinations Oppo A5 support, but we can check it from modem logs.
You can get it easily from your phone. Here is instruction: https://mt-tech.fi/en/how-to-get-4g...droid-phone/#OnePlus,_Oppo_and_RealMe_devices . Could you please then send it to https://cacombos.com/contribute so i can analyze log file and then list all supported 4G combinations?
I already have some Oppo devices listed: https://cacombos.com/search?key=Oppo

Whenever I end a log, the log file has to be sent to oppo or it will be deleted. Is there any other way?

This is strange. I don't have Oppo device so i can't test but i think it will prom't after end log some dialog where you can send log to Oppo or not? When this dialog appear can you copy log to safe location so then phone can't delete log file?

Thank you for the modem log. I have parsed your log file and it's CAT4 device so it doesn't support Carrier Aggregation. But it support 64QAM UL so little bit better upload speed.
Your device support LTE bands 1,3,5,7,8,20,28,38,40,41

Oh it's CAT4? I thought this device is CAT6 cause that was what's written on most specs sites for this device, well they could be just an error. But the SOC seems to be capable of up to CAT12 but it's also not always the SOC right?

My mistake I meant X12 LTE Modem not CAT12.
Edit: I just found out X12 LTE Modem is CAT12.

X12 modem support CAT12 but there is no Carrier Aggregation combinations defined. Maybe this is due Carrier Policy or something.
Qualcomm website show what chip support but that doesn't mean manufacturer will implement all features. I think these feature cost more money for manufacturer so they will removed these on low cost devices. But there maybe have different variant with Carrier Aggregation Combinations defined. If there is full image available then there theory possible extract some data.

Well then so Oppo just didn't add support for CA on this device, I guess there's not much I can do about it. Thanks for the help.

Huawei y7p carrier aggregation ( 4g+ )

Hello guys .. im using huawei y7p week ago ... great phone ... my device is updated to android 10 .... the only problem carrier aggregation is not working ... there is no advanced option in menu to enable CA or inside developer mode ... is this phone support CA or not even the cpu kirin 710f support it
+ is there any code or app the find LTE channel bandwith 10/15/20 mhz from huawei device like samsung service mode ?
thanks to all

i find this option inside shortcut maker

I don't know there is any easy way to check Carrier Aggregation support but i think this device support only Contiguous intra-band CA like most of low-cost Chinese devices. I will try this device to my hand and then we know what combinations this device support.
There is no Service Mode exist in Huawei devices.

Yes mostly do inter-band CA... I think you can't get CA enabled with root but you can try. I don't know what CA your Samsung A7 2017 support - if you like you can get log from Samsung so i can list device to my website. Here is instruction: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices . Custom roms use same baseband as stock - these files are normally signed so there is no way to modify.

Even on gsmarea have same specs that doesn't tell both devices modem configuration are same... Could have different supported combinations. But of course we can guess both devices have same combinations configured...

Huawei forum answer me .. the phone not support carrier aggregation .. is this CA merge inside the cpu modem or need extra IC on motherboard to work like wifi ic ... GSMARENA was put fake specs if this phone not support carrier aggregation

They just guessing because there is no public specs about carrier aggregation. That is big problem. That is reason why i have build cacombos.com where i list devices support Carrier Aggregation.

My experience low cost Huawei and other Chinese devices (example Xiaomi, Realme) support only Carrier Aggregation Combinations used in China and Contiguous Intra-band CA. But please wait - i will test soon this device when i get so i will update then details.
Example CA i think this support is 1C, 3C, 7C, 38C; 40C, 41C and then 1+3.

Yes 3C mean 1800+1800 contiguous intra-band carrier aggregation and yes Redmi Note 8 support that: https://cacombos.com/device?model=M1908C3JG

About redmi note 8 ... gsmarena shows support 4CA .. and the qualcomm Cpu support only 3CA ... Your site shows 2CA intra band ... Whats correct ?

I don't know why it says 4CA in Gsmarea... there is too much wrong details about CA... Yes Qualcomm modem support that but Xiaomi seems haven't implement 3CA feature - i just guess more combinations -> more expensive. It's very common Redmi series support only 2CA because in China CA is much used.
My site data is based of modem logs - if you like you can confirm it in UE Capability Information message. Here is instruction how you could get it from modem: https://mt-tech.fi/en/how-to-get-4g...hone/#Method_for_Qualcomm_Devices_before_2020
