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.

Is there any way that I can buy the EU\Asia or Chinese variant of OnePlus 3 in US from OnePlus or flash a custom ROM or kernerl to get LTE Band 3 on the US variant?
OnePlus AMA going on over @ Reddit, there is no 32GB model coming.
https://www.reddit.com/r/Android/comments/4o308u/oneplus_ama_oneplus_3dition/
as all three models are sporting the Snapdragon 820 you will most likely find it is a ROM lock to certain bands and so flashing the EU/Asia ROM will open up Band 3, Otherwise CM13.
i am interested in finding this out also?
thank you

It actually might be locked on the Modem side.
Since there were tools to unlock the Bands for OP1, there might some tools coming to do the same for OP3.
Did anybody find a modem file to flash? Or a way to do this?

why would you bump a 3 month old thread instead of the latest one with research and info about people doing it?
I am about to order the Redmi Note 5 AI (Global) and just realised that the code name is still whyred.
So, we have the Indian (RN5 pro), China Ai and Global Ai whyred code-named phones! (to the best of my knowledge)
MIUI Roms do try to specify the difference but most custom Roms just says whyred.
The three whyreds have different LTE bands, therefore, they have different Modems.
I have searched all the threads here in xda about the differences in the modems but not yet clear on the following questions:
1) If I flash Chinse Ai Rom on Global Ai whyred, do I have to still flash Global Ai Modem?
2) Does flashing Global Ai Rom on Chinese Ai phone Unlock more LTE bands
3) What happens if I flash Global Ai Rom on Indian RN5 pro, will it gain more LTE bands?
4) Finally, will flashing general whyred custom Rom affect the Modem or LTE bands in the whyred phones?
5) Final Finally, Can someone explain to me flashing Modems and Anti Roll Back feature? does ARB affect flashing Modems?
Please I need some answers here and if you can use the question number reference while answering any of the questions
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 ?

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

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.
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.
