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?

Had anybody been able to flash the Hong Kong T705 update to a Canadian T705? The Canadian model is SM-T705W vs SM-T705 (US and most of the world)... I haven't been able to flash ANY T705 firmware other than the Canadian firmware which is kind of old (Even the KitKat rom).
Any ideas??
EDIT: My tablet is locked, currently waiting for an unlock code. But can't seem to find any info on whether or not this will actually make a difference.

Your best bet is to sell off your Canadian version for a dirt cheap price on ebay and get an International SM-T705 version instead, as firmware updates for localized versions are usually wayy too long to wait or nonexistent.
If you have any trouble with your unlock code go to cellunlocker.net
They had me my code in two hrs and it worked first try.
No BS, no runnarround.
this is how I unlocked my T705W
Cheers!

Joe... Did unlocking the tablet allow you to flash an international T705 firmware? Like the HK Lollipop update? Or are we still stuck with the KitKat 705W firmware?
Not the international one but I did flash the IronRom V1.1.5 T705. This broke my imei and gave me null/null.
The rom worked but radio did not. So I flashed back to stock and radio came back.

Did you try flashing the HK firmware or just the Ironman? Appreciate the replys as this is currently driving me crazy. I bought this tablet 3 weeks ago thinking I would be able to flash Lollipop, only to find out that our Canadian LTE models seem to be locked down and will probably never receive the Lollipop update...

just the Ironman. Patience young grasshopper
For this device it is a bit late, but I notice curous behaviour from observed lte speeds on the SM-t705w klimtkltecan; at leatst my hardcopy of the kilmtkltecan on a t-mobile sim seems to have up/down speeds throttled at 0.5 mbps each on the ookla speed test. Another curious thing is that klimtltecan is the only klimtelte with a upgraded bootloader SW ver 2 with downgrade not possible. Another curious thing is that the kitkat modem does not beget a recognised sim (at least with upgraded lollipop bootloader). Another curous thing unique thist his post in regards to klimtltecan on xda is that it shares a mostly compatible kernel with chagallltecan (sm-t805w), whihc is reason klimtlte roms dont boot on klimtltecan. So, lots of questions there are. Most of all i can't believe the throttleing bs.
So, cna i ask what everyone's speed resutls are on this device sm-t705w klimtltecan?
thanks.

I found out there're 3 different models here.
North America model
Europe / Asia model
China model
Since we are close to China, I think I'm getting a China model. What's bugging me is I don't know if custom ROMs posted in OP3 Android Development sections will compatible with China model. I came from a device which have 14 different models with single-dual sim & regional mixed it's all so confusing that I ended up flashing incompatible ROMs several times. Can anyone help me confirm that please?
Just got my Chinese model today. Unlocked bootloader, flashed OnePlus3Oxygen_16_OTA_011_all_1607052050_0e5983ace5314161 and rooted. Everything seems to work fine.
It came with Hydrogen OS (and full of Chinese crapware)

Could you flash a North American model baseband to test if the China model and US model are essentially the same? Both of the two are named A3000 after all.

Hi guys. I've just found out that there are different versions of Lenovo P2. I've found the p2a42 version on the cheap (less than 190€) but it has no B20 LTE. Is it possible to unlock this band considering the fact that there are some versions that have it active? And apart from LTE bands are there other differences between other phone versions?
Are you sure it doesn't support b20?
Mine does it, that's why I'm asking.
If it's really a version without b20,
you should only buy it, if you can live without it.
I didn't hear of an unlock method for the P2.
Best regards
There are ONLY 2 versions in terms of hardware.
P2a42 has 32GB storage and has B20. (International version )
P2c72 has 64GB storage and does not have B20. (Chinese version )
However, you may get confused because sometimes they take the p2c72 hardware and put the p2a42 software (to get English rom).
You can search p2c72 on these forums for more info.
i have c72 hw but came fashed with a42 .... is my bootloader already unlocked? how to verify if it's locked?
following. i especially want band 28 700mhz and band 7 2600mhz unlocked

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 !
Nobody can help me ?

Let us know if you're making progress... Trying the same thing with a K30 pro.
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.
