Hello. Please help me. I have a Poco F3 with Miui 12.5 and Android 11. I tried to lock LTE band on B7 using radio band mode, but it did not work. Is there a way to solve this problem?!

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)

Use netmonster app and see yourself which band currently available for in your area

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

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.
Is there anyway to use CDMA network on Poco F3 ? May xiaomi.eu rom bring this future ?
This is a GSM phone, it does not have a CDMA modem in the first place.
