Carrier Aggregation - Xiaomi Redmi 6 Pro Questions & Answers

Does redmi 6 pro support carrier aggregation ? The chipset does support it but i think xiaomi has disabled it .
Does it work in custom rom or Mi A2 lite ?

On cacombos.com this device is not yet listed so please submit your device log to cacombos.com/contribute so then could listed and see if it support Carrier Aggregation.
I think this device do not support well due limitation of RF. Example A2 have very limited support: https://cacombos.com/device/M1805D1SG

I don't know about mi a2 lite , but the stock ROM on R6P doesn't support it .my carrier supports it though . Chances are r6p doesn't have the additional hardware required .

Carrier Aggregation Band Combinations

Hi , Where can i find the Carrier Aggregation Band Combinations , for the Redmi Note 8 Pro Global Model ?
For exemple B3+B7+B28 or B1+B7 ....
I know it's 3CA , but there's no info about Band Combinations , inter-band , intra-band ...
About this Carrier Aggregation , is there a difference between global rom and EU rom ?
I just found this : LTE FDD: B1/B2/B3/B4/B5/B7/B8/B20/B28
LTE TDD: B38/B40
but no info on CA .
With Engeneer code *#*#3646633#*#* , i can see bands , but no Carrier Aggregation Band Combinations .
I searched everywhere , but I did not find anything concerning the Carrier Aggregation Band Combinations .
I just found an option to activate CA .
Tengo el mismo inconveniente... B7+B28=4G+ (Chile)

After many tests, it is obvious that some applications like Netmonster are not always reliable.
The best way to check for the presence of any aggregation is to check with the code *#*#4636#*#*
You have to enable developer mode to use the code: Go to "Settings", "About phone", and click 7 times on "MIUI version" .
Hi
I think we can see carrier Aggregation Band Combinations available on Qualcomm with QPST Flash Tools , QxDM Professional , LTE Band Calculator ...
Is it possible to find the carrier Aggregation Band Combinations available on RN8 Pro Mediatek with Maui Meta , EFT dongle , SP Tool MTK + FlashROM ... ?
Thank you
I have build CA Combo databases, but i don't have Xiaomi Redmi 8 Pro combos. I think closest i have Redmi Note 8 https://cacombos.com/device?model=M1908C3JG or Redmi Note 8T: https://cacombos.com/device?model=M1908C3XG
You can collect these from your device. I have instruction for that: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/ (Check Xiaomi section) Can you then send logs to [email protected] (with your phone model number and provider name) so i can parse these and update combos to my site? If you also have any other device, you can try get CA combos out so we can build together better database.
There is also another database https://smartphonecombo.it/ but there neither have Redmi 8 Pro.
I think RN 8 Pro supports only B1+B3... I have problem with that because it is not enabled B3+B20 in this device. With RN 8T and Mi 9T Pro everything works fine...
With RN 8 Pro (EEA) I don't have nowhere 4G+ (B3+B20). I noticed in very few location that appears for a second 4G+ (B3 1800+).
If I disable B20 in Engineering mode, I get for a short 4G+ (1800 or 1800+1800 or 1800+2100 or 1800+1800+2100). If I disable B3 I get only 4G (but shows 800+1800 or 800+2100 or 1800+1800 or 800+1800+1800 or 800+1800+2100 or 800+1800+1800+2100). So definetely is some problem/ROM bug with B3+B20 in my case.
You are right - it support 1+3 and Intra-CA. I just got device on my hand and i can confirm these bands and combinations are supported: https://cacombos.com/device?model=M1906G7G
I also noticed problem with aggregation on B3+B20. My network provider recently added B1 in my location so aggregation on B1+B3 started to work, bot not at all 3 carriers like in other device. The same problem I had with other Chinese phone, but is was dedicated for Chinese market. I am surprised by such a savings policy in a not the cheapest model.
Question about carrier aggregation, is it possible to copy the LTE NVRAM configuration files from a phone with 4G+ enabled and replace them to another phone with the same chipset that has it's CA disabled using modem odem meta, I have been looking at this files but don't know where to start

Unlock BAND 20 LTE

Hello folks, i need your help to unlock the band 20 of redmi K30 5G. Currently i have Chinese rom installed .
Is a way to unlock the band 20 ? I saw new Xiaomi MI 10, if you change the rom will enable the band 20 . ( in that case is a software limitation)
In our case ?
Thank you !
Nobody can help me ?

Any update? Id love to own this phone but need band 20 here in switzerland. Its the only one deactivated that i would need
People tried to unlock bands at the poco F1, but, there was no success, And people tried a lot
I found the possible files causing the restrictions on LTE and 5G bands, but I have no idea how to modify them to unlock bands.
In the policyman folder, the files:
- china_msim_restrictions.xml
- disable_nsa_mmwave_bands.xml
- lte_feature_restrictions.xml
regards

These files doesn't unlock B20 - this is hardware limitation. Bands are configured to nvitems but on 5G phones many things changed.
But could you please share to me your modem log file so i can list all hardware supported 4G bands to my cacombos.com website? I have here instruction how to get log file: https://mt-tech.fi/en/how-to-get-4g...phone/#Method_for_Qualcomm_Devices_after_2020 and you can send it to: https://cacombos.com/contribute . This help me understand what bands & combinations this device support.

If you change any ROMs from global to China and vice versa won't unlock the bands. This is locked down with hardware, not software. Older Qualcomm devices could unlock bands with Qualcomm tools/programs. This isn't the case with newer models.

Question LE numbers and applicable models

Can people post here with the LE number shown on your phone under Settings > About Phone > Model so we can compile a list of which device is which?
I haven't been able to find a definitive list, if you know of one then by all means post a link.
Please include your country and provider if it's a provider specific model
I'll start :
LE NumberModelRAMStorage (ROM)LE2123OnePlus 9 Pro (EU)8GB128GBLE2123OnePlus 9 Pro (EU)12GB256GBLE2125OnePlus 9 Pro (US) (Verizon?)12GB256GBLE2127OnePlus 9 Pro (US) (T-Mobile?)12GB256GB
One reason I wanted to do this is because there was MSM released but it says it's for the LE2125 so there's no guarantee it would work for anyone with a OnePlus 9 Pro
LE2125 USA Unlocked, using Verizon.
Edit - 12GG Ram, 256GB Rom
LE2127 T-Mobile edition
12G RAM, 256G storage

You are wrong, Oxygen Updater reads the software not hardware model to determine which update you need. So you have the LE2120 China hardware running the DA (India) ROM

The LE2125 is the US unlocked model and ISN'T carrier specific. It should be compatible with most US carriers (Tmobile, Verizon, AT&T, and their MVNO's, etc.) US-Cellular isnt compatible with any oneplus device unless you know someone on the backend who can whitelist your imei.

N78 5g band

Would it be possible to enable/add n78 (3500) radio support on this device? I have an unlocked SKT variant (LM-F100N). GSMarena however doesn't show n78 on the supported 5g bands, but other sites show it has n78 support.
I'm currently here in the Philippines and it's the only 5g band that all telcos are using afaik.
What app do you use to show what bands are active?
I just look it up on Wikipedia on what are the bands that the local telcos are using. I used GSMArena to check what are the supported bands for LG Wing. It seems like no matter whether SK or international, they all have the same bands
having same issue..Im from the philippines too and my LG wing already have n78 band enabled but still no 5g
There could have Carrier Policy to list networks have allowed use 5G with this device. That is common in most of 5G device have allow list.

If you have rooted you can may edit carrier policy depends how it's made to device and use *#*#4636#*#* menu to enable 5G NR.
Also would be intresting see logs from this device. There is way to get without root https://cacombos.com/contribute -> LG . The Log should have information about supported 4G and 5G combinations of devices and can there confirm if 5G enabled or not.

What you can find under of Debug Screen?
dear XDA " poster " , please find below a link to a page with hypertext and to an application where to browse that sheet for LMF100N [ LG WING variant for KR market ] also supporting " sub6Ghz " radio frequency bands thus compatible with wireless cell networks of a latest generation [ " 5G NR " technology with band n78 too. ]
https://www.piucellulare.it/scheda-tecnica/lg/wing/5g-f100n/ [ google translate might help that website homepage also shows a Eng. version switch at the bottom of the page , footer ]
in connection with LG velvet and wing, our experience instead supports ideas " LGE " develops and deploys firmware, also allowing carriers | operators to select a variant depends on a carrier's brand however in " EU ", some LGE official websites report unlocked " LG variant devices " [ LG devices with no carrier brand ] are compatible with " 5G " wireless cell networks of few carriers only - for instance: LG velvet model we owned had no carrier brand and firmware variant turned the smartphone into a device compatible with " 5G NR " network of select operator of Netherlands only and " KPN " in particular [ the firmware is then enabling few " 5g bands " only and depending on the target market ]
on your " LG WING on SKT network " you may still want to replace firmware and remove carrier brand, you'll be selecting a variant that " unlocks more 5G bands " therefore making your smartphone compatible with a network operator | carrier in your country however firmware variant and version must also eventually match that model marketed in South Korea [ LM-F100N ], in addition you don't want to flash | load firmware that was instead developed and deployed for australia; global or US models of the same device [ Lg WING ]
NOTE:
we include two more links to " pages with hypertext " and websites also listing firmware variants and versions for LG Wing [ LM-F100N marketed in South Korea ] however please also note the size of those files [ .KDZ files ] and the two separate websites are stating very much different file property for those same images for firmware.

I need some help guys. I have the LG V50 thinq 5g but the band is not supported in the philippines (N78). Is there any way to change the band to n78? Thank you

Question Will cross flashing modems open up different bands?

Hi I have an LE2120 cross flashed to global and am currently running nameless. I was wondering if flashing a NA modem would allow me to see all the NA bands including the Verizon UW bands. I ask this since as far as I can tell the hardware is the exact same on all the models with just a change in software. I appreciate your answers. Thank you.
Hi, here is a link with more info regarding you question for/on our device.
Modify OnePlus 7 Pro 5G, 8 and 8 Pro, 9 and 9 Pro NR/LTE-A band combos - MT-TECH.FI
On this instruction we will modify OnePlus 7 Pro 5G, 8 and 8 Pro band combo profiles with Qualcomm software. OnePlus has limited 5G access and 4G+/LTE+ Carrier Aggregation combinations and this instruction help you to unlock. However this instruction doesn’t unlock hardware defined combinations...
