Yes i have the exact same question,,, can we do this?? because non of the custom roms are supporting 4G even after manually updating the apns... any idea please?
i think you have to mess with the processor NV value or something.There is a unlock LTE bands thread here somewhere.It only unlocks LTE bands for Qualcomm based phones.Doesn't not add new bands that were not there to begin with but just unlocks them.LTE Apn's won't work unless the band is avaliable, you will just get HSPA or HSPA+.Note 4 snapdragon does have band 3 support, so you're in luck but the process is very risky as it involves editing the heart of your device.I was about to do it but it was too risky lol.Lots of people have had success with the unlocking, notiably Samsung users.

were you able to make it work?
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?
Hi, I´m from Portugal and my Carrier is MEO. For 4G they support band 20/3/7.
I want to buy LeTV LeEco Le Pro 3 X727 and it says he only supports 4G FDD-LTE: 2/4/5/7/12/17/29/30/38.
LeEco Le Pro 3 X720 support 4G FDD-LTE: B1/2/3/4/5/7/8/20.
IF i install Lineage rom, or another Rom for X720 on x727 model, do he gonna support the same bands as 720? the 2/7/20?
Thx in advance and sorry for my poor English.

This is not right. X727 have band 3 100%...
Yes I confirm it has B3, I checked on the official LeEco website.

Also to answer your question, the supported bands are written to the NVRAM of the phone and aren't part of the rom. So no, if you flash a X720 rom on an X727 you won't unlock any addition bands.

Yeah, the baseband chip support all bands as it's part of the SoC. The modem driver is kind of generic. It reads a bit of read only storage on the phone called NV_RAM which contains stuff like the bands the phone supports, the IMEI, etc. So it is sometimes possible to unlock additional bands by editing the NV_RAM

So editing this in the Build.prop makes all x720 custom roms compatible with x727 (in theory)
*EDIT - Of-topic: Melbourne look likes the best city ever. Moving as soon as possible
I have the LEX 727 from Amazon but no working bands 2 or 4, any ideas to help me? changing the rom to the chinese version? something in the modem, baseband?

NVRAM isn't in the build prop, its a special bit of persistent memory in the phone. To edit it you need to put the phone into diagnostic mode and use QPST.
And yeah, Melbourne is pretty sweet. I hope to see you here soon!
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 !

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.
