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.

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 !!

Network Band Frequency

HI,
I operate a Note Pro 5 in the UK on the plusnet network which uses the following bands / frequency's. I use the global ROM
800MHz band, the 1800MHz band, the 2100MHz band
Iam not having much luck with the 4G speed / connection. Iam wondering if that's because the handset does not work with these bands. No point reformatting my phone only to find out if the phone does not work with these bands !!!
Thanks
Mathew

It should work fine, as they use EEs network. I use virgin mobile that also uses EEs network and its fine. Have you tried amending the APN settings?

Yes you are correct Virgin and Plusnet both run off EE but its not that simple.
EE only allow some bands to be avalible for resale the ones I have listed are what Plusnet use.
You have pointed out something I should have done!!!! I have removed the APN and started from scratch I will try this for a few days and see what happens.

So from what I've read plusnet don't seem to offer the 800mhz frequency (EE/virgin do), but if your Redmi Note 5 is the global version it will work with all UK 4G bands (including 800 or band 20 if its available from your provider). Usually band 20/800mhz travels further and so tends to be used more in rural areas to help improve coverage. Were you connecting to 4g OK before or have you just changed to plusnet or just got your RN5?

Yes I thought that but have had conformation directly from Plusnet that they do use the 800mhz range

@MathewRB
Global version of Redmi Note 5 supports all frequences You mentioned. The only problem is that it doesn"t support carrier agregation (LTE+) which can lead to slow data acces when the transmitter which Your"s phone is connected to is clogged

Thats a good bit of information looks like Iam finding more and more of reason (excuse) to upgrade to the 7 Note Pro. But when is the 8Note Pro due to come out any idea?

Thank you!!! I got the phone today and am getting LTE , that was the main reason for getting rid of the china model . thanks for your help

No 4G+ No voLTE

I purchased a Note 8 pro, and I noticed that with Vodafone Italia it does not aggregate nor the bands and I do not have the voLTE, although in the settings it is active.I obviously put the sim to check it was not a temporary disservice and in the Mi 9 I have both 4G + is the voLTE. The model is obviously European EU MIUI 11.

Activated MIMOX4 and CA in MIMO via engineering mode, this will enable LTE-Advance aka LTE+
You should check enable feature, other is depending on your network support and how much you want sacrifice mAH for max speed

I live in Italy too...Have you solved the problem? I'm thinking of buying this phone too, but I want to know about carrier aggregation...what have you managed to get? 2CA or 3 CA? Anyone else have better information about CA? The bands used in my country are B1 B3 B7 and B20 (B32 too but it is supported only on high-end devices).

I have not tried it yet, but I am disappointed being an EU model that does not aggregate bands and does not even support voLTE. everything works well on the Mi9, also an EU model.

Yo soy de chile, y el Carrier Aggregation, es posible juntando dos bandas B7 (4G)+B28 (4G) = 4G+, pero no logro que conecte kas dos bandas en simultáneo

What application is used to check the connected bands? I activated CA and MIMO but nothing has changed. Could someone send a screenshot of what the configuration should look like in engineer mode? Thanks.

*#*#3646633#*#* works on global, i tried, dunno about other versions, try again if u still got global. after restart has some lag before accessing the menu.
its my wifes phone, i have mi 8, also, she ported the number few days ago, tried my sims in her phone and it shows option Use Volte, is checked but when i input *#*#4636#*#* it aint activated volte and wifi calls ... may its a sim problem. also looses carrier a lot, mobile data sucks ... and before the portation didnt had those problems
also, seen on mi.com version 11.0.6.0 based still on pie, after a search on google i saw (pakistan release) 11.0.2.0 android 10... wierd

I think it has something to do with " LTE Physical Channel Configuration "
comparing my Redmi Note 7 pro, It has open and close curly bracket while my Redmi Note 8 pro. There is config written on it.
I've seen a link. Its the same issue regarding 4G+ enabled, I didn't test yet

I hope some will come up a version for Redmi Note 8 pro
