Add LTE Band 3 to OP3?

Hi guys, so after a bit of research I found that you can add/enable bands on the OP1 as shown here
http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
and Here
http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455
My question is can I add LTE band 3 to my OP3 A3000?
Mine currently supports:
North America model(A3000)
FDD-LTE: Bands 1/2/4/5/7/12/17/30
The other models support:
Europe / Asia model
FDD-LTE: Bands 1/3/5/7/8/20
TDD-LTE: Bands 38/40
China model
FDD-LTE : Bands 1/3/7
TDD-LTE: Bands 38/39/40/41
If anyone has done this or attempted to do this please let me know

Looking for the same information.

Also been searching for this. Found another thread which says hopefully in the next month or two it will be looked into.

Could this even be possible? Aren't bands hardware dependant?

Its possible to add bands in Qualcomm devices .. i added h+ band in my Xiaomi mi note 1year ago. (Snapdragon 801) ... Somewhere in xda exist a tutorial to add bands in xiaomi mi note pro. Try the steps in oneplus ... But make sure you nandroid backup and EFS backup.

This is what I'd assume as well, but it looks like some have been successful in the past with Oneplus devices. Especially since Oneplus' response to the band omissions seemed a bit vague IMO.

Any updates?
I have a A3000 US model (Does not support LTE band 3)
AND NOW
I have just got a A3000 HK model (For my dad) (support's LTE band 3)
and the "about phone" part is identical apart from the baseband version.
Is there any way to tell them apart. And does this mean I can somehow unlock LTE band 3 on my US version of the OP3?
If there was someway to backup the basband and restore it on on my US OP3 that would also be great!

The HK model is A3003 so you actually have a China model.

Opps, either way, it still has LTE band 3 which I need on my US version

Any news on adding bands to the OP3?

AFAIK there isn't yet a way, but I would suggest to follow the most active thread on the subject:
http://forum.xda-developers.com/oneplus-3/help/unlocking-lte-bands-t3425871/page6
Hopefully something will come up..

Can this work on all carriers? Whether in North America or over seeas?

I've got OP3T A3000, tried multiple files and instructions to unlock LTE band 3 on it, no luck so far. Downgraded to Nougat, Oreo, different zip files, qcn files, hex editing stuff, most of these process went error free with still no band 3.

Hello..
I own a China "Global" Edition Redmi Note 5.
I'm on MetroPCS (T-Mobile towers) and I get LTE in the Urban (City) areas and HSPA+ on the outskirts. It NEVER drops down to 3G or (Heaven Forbid) 2G.. I'm pretty sure AT&T provides the best overall coverage.. but MetroPCS has the best cost for my needs.. hope this helps if you have a Global Edition.

How can I find out with certainty that LTE is covered

In my location considering the li ited amount amount of 4G Bands the Mi Max 3 handles? I don't mind using ATT or T-Mobile but I am less then confident relying on their sale person's answers.
Thanks!

I use Cricket which is part of AT&T...so for 3G and LTE, both signals is quite spot on. I just got mly Mix Max 3 yesterday and i switch my sim from another Xiaomi device to give you an idea that Xiaomi Phones can handle that company, but you can go to Tmobile and have them test it out.

Global, but have tried Chinese Rom.. there is no difference.

Celmapper uses data collected by volunteers using the cellmapper apps for Android and IOS. It will show you LTE and GSM bands used in areas where volunteers have collected data. https://www.cellmapper.net/Index

I have exactly the same question:
According to official Mi Max 3 website:
LTE band support: B1, B3, B4, B5, B7, B8, B20
I just bought a Global version model: M1804E4A:
The user guide indicates band support: 1/3/7/8/20/34/38/40 (Bands 4 & 5 are missing !!??)
WIthout Bands 4 & 5 - I'm guessing I can't get onto AT&T and TMobile ?
ALso is there a code dialler to check what LTE band is being support by model: M1804E4A?
For folks using mi max 3 in USA successfully - may I know what is your model number?
Thanks !!

I see 3 model variants on various websites: M1804E4A , M1804E4C, M1804E4T - anyone knows what the differences are?
Thanks !!

Screenshot from same global model. All those listed online are supported. Looks like they copied user guide from Mi Max 1/2 to save money...
For model #s nobody knows and until we start collecting data nobody will know for sure. My guess would be China 4GB and 6GB RAM, and Global. Second guess - diffident hardware variants regarding display and touchscreen, 2 each in kernel -> 4 possible configurations...

Wow thanks for your reply, how do you you get your phone to display the LTE bands? Is it difficult to do? Thanks

Change LTE bands (Unlock band 20)

Hi all
I bought a Chineese Version of the Redmi Note 8 pro. I installed now V10.4.1.0 Global Rom and it works. Last problem is that i need band 20 to have a good 4G connection.
Is it somehow possible that i can unlock and set this band ?
Kind Regards

You cant add new BANDS. China modem no support him !Re-flashing does not help!

Yes, but you have probably the global version. I have only 4G on the Chinese one. Until I go on holiday to China, where it will be 4G+!

Yes. I have EU version. I thought that I cant have 4G+ like on Note 7 , because this RN8 pro dont have all bands..

has anyone been able to access Engineer Mode? Mediatek SoCs used to be able to enable bands through it.

cool, but has anyone verified if changes in BandMode enable LTE bands? The G90T has the WorldMode modem and is capable of picking up just about every LTE band used throughout the world.

Redmi NOte 8 Pro has big problems with LTE 4G + tape management. The phone does not keep the 4G + it switches and stays in 4G all the time. It's a modem management problem that does not support the double-banding needed for 4G +.

Hello, could you please specify what kind ofLTE band issues this phone have? I've just ordered Global vers. with 128 GB ROM, where Band 20 (800) is the most important for me, as it is the most frequently used one in Türkiye. It doesn't exist in my Mi5, so hope the signal and speed would be better with Redmi Note 8 Pro.

anyone played around with trying to unlock more bands? pretty sure the modem has the ability to get them all, and is just software locked for one reason or another

Even I go to engineering mode. It still cannot unlock the band 7 / 20.
it seem Chinese version cannot unlock the band.
I hope some expert can do it later and share with us.

How do you use themes?

what do you mean by "tape management"? If it's a modem management problem, then it is software related. Helio G9T's HAVE the WorldMode modem, what you're describing doesn't make sense and doesn't answer my question.

it's probably a modem firmware issue. the problem is the Helio G90T is only available on the RN8 Pro, so swapping modem firmware from another device isn't happening. I wonder if anyone with the Global variant has tried though.

I have Note 8 pro Global Version and band 7,20 is enable by default.

may work
