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...

I am curious whether flashing the baseband on the China Redmi note 5 pro will unlock LTE band 20.
Anyone tried it before on another Redmi device?
Or is there a sure fire way of unlocking B20?
No, it doesn't work that way with Qualcomm modems. You can't do software unlock cause there's nothing to unlock, it's all hardware.
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
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
Excuse my writing (I am using Google Translate)

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.
Hello all.
I just bought a Xiaomi Note 8T and i realiced i have received a EUROPEAN version and i need the GLOBAL version.
My country (argentina) uses LTE bands 2, 4, 7, 8, 28, and my phone just have 7, 8 and 28. So, i don't know if the phone will work fine because i dont have the band 4, very important band in Argentina.
1) Can i unlock the band 4 in the european version? there is a chance modifying the firmware or is a hardware process? I readed some guides, like this https://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774 , but just i dont know if that it may work.
2) If i flash a GLOBAL ROM, this may work?
Thanks.
bump, I have this issue too.
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

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.
